If March 31st is backup day, dont be fooled with restore on April 1st

With March 31st as world backup day, hopefully some will keep recovery and restoration in mind to not be fooled on April 1st.

Lost data

When it comes to protecting data, it may not be a headline news disaster such as earthquake, fire, flood, hurricane or act of man, rather something as simply accidentally overwriting a file, not to mention virus or other more likely to occur problems. Depending upon who you ask, some will say backup or saving data is more important while others will standby that it is recovery or restoration that matter. Without one the other is not practical, they need each other and both need to be done as well as tested to make sure they work.

Just the other day I needed to restore a file that I accidentally overwrote and as luck would have it, my local bad copy had also just overwrote my local backup. However I was able to go and pull an earlier version from my cloud provider which gave a good opportunity to test and try some different things. In the course of testing, I did find some things that have since been updated as well as found some things to optimize for the future.

Destroyed data

My opinion is that if not used properly including ignoring best practices, any form of data storage medium or media as well as software could result or be blamed for data loss. For some people they have lost data as a result of using cloud storage services just as other people have lost data or access to information on other storage mediums and solutions. For example, data has been lost on cloud, tape, Hard Disk Drives (HDDs), Solid State Devices (SSD), Hybrid HDDs (HHDD), RAID and non RAID, local and remote and even optical based storage systems large and small. In some cases, there have been errors or problems with the medium or media, in other cases storage systems have lost access to, or lost data due to hardware, firmware, software, or configuration including due to human error among other issues.

Now is the time to start thinking about modernizing data protection, and that means more than simply swapping out media. Data protection modernization the past several years has been focused on treating the symptoms of downstream problems at the target or destination. This has involved swapping out or moving media around, applying data footprint reduction (DFR) techniques downstream to give near term tactical relief as has been the cause with backup, restore, BC and DR for many years. The focus is starting to expand to how to discuss the source of the problem with is an expanding data footprint upstream or at the source using different data footprint reduction tools and techniques. This also means using different metrics including keeping performance and response time in perspective as part of reduction rates vs. ratios while leveraging different techniques and tools from the data footprint reduction tool box. In other words, its time to stop swapping out media like changing tires that keep going flat on a car, find and fix the problem, change the way data is protected (and when) to cut the impact down stream.

Here is a link to a free download of chapter 5 (Data Protection: Backup/Restore and Business Continuance / Disaster Recovery) from my new book Cloud and Virtual Data Storage Networking (CRC Press).

Is 14.4TBytes of data storage for $52,503 a good deal? It depends!

A news story about the school board in Marshall Missouri approving data storage plans in addition to getting good news on health insurance rates just came into my in box.

I do not live in or anywhere near Marshall Missouri as I live about 420 miles north in the Stillwater Minnesota area.

What caught my eye about the story is the dollar amount ($52,503) and capacity amount (14.4TByte) for the new Marshall school district data storage solution to replace their old, almost full 4.8TByte system.

That prompted me to wonder, if the school district are getting a really good deal (if so congratulations), paying too much, or if about right.

Industry Trends and Perspectives

Not knowing what type of storage system they are getting, it is difficult to know what type of value the Marshall School district is getting with their new solution. For example, what type of performance and availability in addition to capacity? What type of system and features such as snapshots, replication, data footprint reduction aka DFR capabilities (archive, compression, dedupe, thin provisioning), backup, cloud access, redundancy for availability, application agents or integration, virtualization support, tiering. Or if the 14.4TByte is total (raw) or usable storage capacity or if it includes two storage systems for replication. Or what type of drives (SSD, fast SAS HDD or high-capacity SAS or SATA HDDs), block (iSCSI, SAS or FC) or NAS (CIFS and NFS) or unified, management software and reporting tools among capabilities not to mention service and warranty.

Sure there are less expensive solutions that might work, however since I do not know what their needs and wants are, saying they paid too much would not be responsible. Likewise, not knowing their needs vs. wants, requirements, growth and application concerns, given that there are solutions that cost a lot more with extensive capabilities, saying that they got the deal of the century would also not be fair. Maybe somewhere down the road we will hear some vendor and VAR make a press release announcement about their win in taking out a competitor from the Marshall school district, or perhaps that they upgraded a system they previously sold so we can all learn more.

With school districts across the country trying to stretch their budgets to go further while supporting growth, it would be interesting to hear more about what type of value the Marshall school district is getting from their new storage solution. Likewise, it would also be interesting to hear what alternatives they looked at that were more expensive, as well as cheaper however with less functionality. I’m guessing some of the cloud crowd cheerleaders will also want to know why the school district is going the route they are vs. going to the cloud.

IMHO value is not the same thing as less or lower cost or cheaper, instead its the benefit derived vs. what you pay. This means that something might cost more than something cheaper, however if I get more benefit from what might be more expensive, then it has more value.

Industry Trends and Perspectives

If you are a school district of similar size, what criteria or requirements would you want as opposed to need, and then what would you do or have you done?

What if you are a commercial or SMB environment, again not knowing the feature functionality benefit being obtained, what requirements would you have including want to have (e.g. nice to have) vs. must or have to have (e.g. what you are willing to pay more for), what would you do or have done?

How about if you were a cloud or managed service provider (MSP) or a VAR representing one of the many services, what would your pitch and approach be beyond simply competing on a cost per TByte basis?

Or if you are a vendor or VAR facing a similar opportunity, again not knowing the requirements, what would you recommend a school district or SMB environment to do, why and how to cost justify it?

What this all means to me is the importance of looking beyond lowest cost, or cost per capacity (e.g. cost per GByte or TByte) also factoring in value, feature functionality benefit.

Ok, nuff said for now, I need to get my homework assignments done.

Why SSD based arrays and storage appliances can be a good idea (Part II)

This is the second of a two-part post about why storage arrays and appliances with SSD drives can be a good idea, here is link to the first post.

So again, why would putting drive form factors SSDs be a bad idea for existing storage systems, arrays and appliances?

Benefits of SSD drive in storage systems, arrays and appliances:

  • Familiarity with customers who buy and use these devices
  • Reduces time to market enabling customers to innovate via deployment
  • Establish comfort and confidence with SSD technology for customers
  • Investment protection of currently installed technology (hardware and software)
  • Interoperability with existing interfaces, infrastructure, tools and policies
  • Reliability, availability and serviceability (RAS) depending on vendor implementation
  • Features and functionality (replicate, snapshot, policy, tiering, application integration)
  • Known entity in terms of hardware, software, firmware and microcode (good or bad)
  • Share SSD technology across more servers or accessing applications
  • Good performance assuming no controller, hardware or software bottlenecks
  • Wear leveling and other SSD flash management if implemented
  • Can end performance bottlenecks if backend (drives) are a problem
  • Coexist or complemented with server-based SSD caching

Note, the mere presence of SSD drives in a storage system, array or appliance will not guarantee or enable the above items to be enabled, nor to their full potential. Different vendors and products will implement to various degrees of extensibility SSD drive support, so look beyond the check box of feature, functionality. Dig in and understand how extensive and robust the SSD implementation is to meet your specific requirements.

Caveats of SSD drives in storage systems, arrays and appliances:

  • May not use full performance potential of nand flash SLC technology
  • Latency can be an issue for those who need extreme speed or performance
  • May not be the most innovative newest technology on the block
  • Fun for startup vendors, marketers and their fans to poke fun at
  • Not all vendors add value or optimization for endurance of drive SSD
  • Seen as not being technology advanced vs. legacy or mature systems

Note that different vendors will have various performance characteristics, some good for IOPs, others for bandwidth or throughput while others for latency or capacity. Look at different products to see how they will vary to meet your particular needs.

Cost comparisons are tricky. SSD in HDD form factors certainly cost more than raw flash dies, however PCIe cards and FTL (flash translation layer) controllers also cost more than flash chips by themselves. In other words, apples to apples comparisons are needed. In the future, ideally the baseboard or motherboard vendors will revise the layout to support nand flash (or its replacement) with DRAM DIMM type modules along with associated FTL and BIOS to handle the flash program/erase cycles (P/E) and wear leveling management, something that DRAM does not have to encounter. While that provides great location or locality of reference (figure 1), it is also a more complex approach that takes time and industry cooperation.

Locality of reference for memory and storage
Figure 1: Locality of reference for memory and storage

Certainly, for best performance, just like realty location matters and thus locality of reference comes into play. That is put the data as close to the server as possible, however when sharing is needed, then a different approach or a companion technique is required.

Here are some general thoughts about SSD:

  • Some customers and organizations get the value and role of SSD
  • Some see where SSD can replace HDD, others see where it compliments
  • Yet others are seeing the potential, however are moving cautiously
  • For many environments better than current performance is good enough
  • Environments with the need for speed need every bit of performance they can get
  • Storage systems and arrays or appliances continue to evolve including the media they use
  • Simply looking at how some storage arrays, systems and appliances have evolved, you can get an idea on how they might look in the future which could include not only SAS as a backend or target, also PCIe. After all, it was not that long ago where backend drive connections went from propriety to open parallel SCSI or SSA to Fibre Channel loop (or switched) to SAS.
  • Engineers and marketers tend to gravitate to newer products nand technology, which is good, as we need continued innovation on that front.
  • Customers and business people tend to gravitate towards deriving greatest value out of what is there for as long as possible.
  • Of course, both of the latter two points are not always the case and can be flip flopped.
  • Ultrahigh end environments and corner case applications will continue to push the limits and are target markets for some of the newer products and vendors.
  • Likewise, enterprise, mid market and other mainstream environments (outside of their corner case scenarios) will continue to push known technology to its limits as long as they can derive some business benefit value.

While not perfect, SSD in a HDD form factor with a SAS or SATA interface properly integrated by vendors into storage systems (or arrays or appliances) are a good fit for many environments today. Likewise, for some environments, new from the ground up SSD based solutions that leverage flash DIMM or daughter cards or PCIe flash cards are a fit. So to are PCIe flash cards either as a target, or as cache to complement storage system (arrays and appliances). Certainly, drive slots in arrays take up space for SSD, however so to does occupying PCIe space particularly in high density servers that require every available socket and slot for compute and DRAM memory. Thus, there are pros and cons, features and benefits of various approaches and which is best will depend on your needs and perhaps preferences, which may or may not be binary.

I agree that for some applications and solutions, non drive form factor SSD make sense while in others, compatibility has its benefits. Yet in other situations nand flash such as SLC combined with HDD and DRAM tightly integrated such as in my Momentus XT HHDD is good for laptops, however probably not a good fit for enterprise yet. Thus, SSD options and placements are not binary, of course, sometimes opinions and perspectives will be.

For some situations PCIe, based cards in servers or appliances make sense, either as a target or as cache. Likewise for other scenarios drive format SSD make sense in servers and storage systems, appliances, arrays or other solutions. Thus while all of those approaches are used for storing binary digital data, the solutions of what to use when and where often will not be binary, that is unless your approach is to use one tool or technique for everything.

Are social media and networking a waste of time?

Are social media and networking including twitter, blogs, google+ and linkedin among other venues and mediums a waste of time or only for those who have nothing else to do?

As with most things, the answer is it probably depends.

However IMHO the answer is NO, social media and networking when incorporated as a part of doing business is not a waste unless like anything else you let it become a waste of time.

I have chosen to leverage social media networking along with traditional mediums, venues, news letters, in person events, and other means of communicating, learning and doing business vs. ignoring it.

Does that I mean I jump on or join in every new social networking medium or venue? Nope, however I’m always watching to see where to invest time and effort and find the return or benefit.

 

Some observations about social media and networking include:

You get out of social media and networking what you put into it: When it comes to LinkedIn, Michael Naylor told me several years ago to get involved with and you will get out of what you put into LinkedIn (or other venues for that matter). Now about eight or nine years later, even despite the spam, I completely agree how true Mikes advise has been and remains.

Engagement, interaction, discussion (or debate) are all part of the discourse in and around social media and networking. Louis Gray who got me hooked on twitter and some other mediums years ago has a great blog post that unless you are engaging or interacting, you are not social networking. What that means is simply using social networking media and mediums as a broadcast or one way communication platform is just that, talking at vs. talking with or too people. Thus get out of your comfort zone, step out from behind your pulpit or podium and engage with audiences or participants vs. talking at them to get out of what you put into it.


Dont be afraid of joining different groups or venues, listen, lurk, observe, learn from others in the same or adjacent areas online, however also keep time in perspective to get other tasks completed. This also means you can build your own castle or venue for people to come to or you can do a hybrid including your own site(s) as well as taking discussions and conversations to where other audiences are.

Let me put this a different way, I like to fish and catch. Sometimes I know where the fish are based on experience and when they might bite, then there are other times when they move. This means knowing when and where to go to different locations to catch a fish or catch a conversation.

Going where the fish are, fall on the St. Croix river

Building on the above, don’t be afraid to get involved or start a conversation.

Sure on some venues you will get spammed and a bunch of responses that you might not like particular if venturing out away from the safety of your own castle or site. However use those conversations and engagements to learn and interact, see what is on people’s minds or that they are interested in vs. what you want to tell them.

Where wasting time can come into play is trying to be part of every discussion, watching what everybody is doing or saying in all the various venues. For the trick has been to pick which venues are useful for where I want to invest time along with what I will get out of them in addition to using different tools to help find the applicable conversations and discussions. If you are not using things as basic as Google alerts you are probably spending too much time out looking for conversations or discussions, or, you are missing out on them altogether.

I have also noticed that there tends to be a correlation between those who are involved in one way communication and comment diminishing or dismissing social media and networking as a waste of time or not practical, hmm, go figure.

Otoh, I have also noticed those who tend to be involved in one way or non interactive discussions or that limit comments and discourse tend to also have lower numbers of followers, appear on fewer lists or get shared by others, hmm, go figure.

I have also noticed that some who do very well in cyberspace may not do as well in person and vise versa, however there are many who can do both. Likewise there are those who do well in columns that support interactive comments and those who do not.

Perhaps there is a hadoop big data analytics algorithm out there for someone who has lots of time to do some research on all of this?

In the meantime, for those interested, check out Johnny Bentwood (@JonnyBentwood) and some of the things he has done around analytics and social media and metrics if so interested.


What this all means is that to each their own, that is comfort zones. If your comfort zone and sphere of influence is in one way communication via print, online, video or what ever, then play to your strengths. Likewise, if yours is as a commentator or something else, go with it.

Leverage and get involved, don’t be scared, find your voice, engage, take part, however also be ready to be challenged while increasing your network of contacts, ability to learn and get out of what ever you put into it. Otherwise, stay in your comfort zone or within your sphere of influence.

As to if social media and networking are a waste of time and only for those who have nothing to do, well, if that is the case, last year was a banner year for me and my business. That is both in terms of activity, contacts, coverage, awards and accolades not to mention increasing discussions and experience in other areas as well as being involved in traditional media and venues or activities. I guess if that is the result of being involved or investing in social media and networking it is an honor to be among those who waste time and have nothing better to do.

Why do I take time out of my busy schedule to share this?

Simple, you get out of things what you put into it, and granted some will simply take advantage as opposed to contributing back, maybe they too will evolve to give back what they take out.

Feel free to engage or simply read and lurk, that option is all yours.

Ok, nuff said for now, have to get some other work projects done now.

Cheers

Researchers and marketers dont agree on future of nand flash SSD

Marketers particular those involved with anything resembling Solid State Devices (SSD) will tell you SSD is the future as will some researchers along with their fans and pundits. Some will tell you that the future only has room for SSD with the current flavor de jour being nand flash (both Single Level Cell aka SLC and Multi Level Cell aka MLC) with any other form of storage medium (e.g. Hard Disk Drives or HDD and tape summit resources) being dead and to avoid wasting your money on them.

Of course others and their fans or supporters who do not have an SSD play or product will tell forget about them, they are not ready yet.

Then there are those who take no sides per say, simply providing comments and perspectives along with things to be considered that also get used to spin stories for or against by others.

For the record, I have been a fan and user of various forms of SSD along with other variations of tiered storage mediums using them for where they fit best for several decades as a customer in IT, as a vendor, analyst and advisory consultant. Thus my perspective and opinion is that SSDs do in fact have a very bright future. However I also believe that other storage mediums are not dead yet although their roles are evolving while their technologies continue be developed. In other words, use the right technology and tool, packaged and deployed in the best most effective way for the task at hand.

Memory and tiered storage hirearchy
Memory and tiered storage hierarchy

Consequently while some SSD vendors, their fans, supporters, pundits and others might be put off by some recent UCSD research that does not paint SSD and particular nand flash in the best long-term light, it caught my attention and here is why. First I have already seen in different venues where some are using the research as a tool, club or weapon against SSD and in particular nand flash which should be no surprise. Secondly I have also seen those who don’t agree with the research at best dismiss the findings. Others are using it as a conversation or topic piece for their columns or other venues such as here.

The reason the UCSD research caught my eye was that it appeared to be looking at how will nand SSD technology evolve from where it is today to where it will be in ten years or so.

While ten years may seem like a long time, just look back at how fast things evolved over the past decade. Granted the UCSD research is open to discussion, debate and dismissal as clear in the comments of this article here. However the research does give a counter point or perspective to some of the hype which can mean somewhere between the two extremes, exists reality and where things are headed or need to be discussed. While I do not agree with all the observations or opinions of the research, it does give stimulus for discussing things including best practices around deployment vs. simply talking about adoption.

It has taken many decades for people to become comfortable or familiar with the pros and cons of HDD or tape for that matter.

Likewise some are familiar with (good or bad) with DRAM based SSD of earlier generations. On the other hand, while many people use various forms of nand flash SSD ranging from what is inside their cell phone or SD cards for cameras to USB thumb drives to SSD on drives, on PCIe cards or in storage systems and appliances, there is still an evolving comfort and confidence level for business and enterprise storage use. Some have embraced, some have dismissed, many if not most are intrigued wanting to know more, are using nand flash SSD in some shape or form, while gaining confidence.

Part of gaining confidence is moving beyond the industry hype looking at and understanding what are the pros, cons and how to leverage or work around the constraints. A long time ago a wise person told me that it is better to know the good, bad and ugly about a product, service or technology so that you could leverage the best, configure, plan and manage around the bad to avoid or minimized the ugly. Based on that philosophy I find many IT customers and even some VARs and vendors wanting to know the good, the bad and they ugly not for hanging out a vendor or their technology and products, rather so that they can be comfortable in knowing when, where, why and how to use to be most effective.

Industry Trends and Perspectives

Granted to get some of the not so good information may need NDA (Non Disclosure Agreement) or other confidentially discussions as after all, what vendor or solution provider wants to show or let anything less than favorable out into the blogosphere, twittersphere, googleplus, tabloids, news sphere or other competitive landscapes venues.

Ok, lets bring this back to the UCSD research report titled The Bleak Future of NAND Flash Memory

UCSD research report: The Bleak Future of NAND Flash Memory
Click here or on the above image to read the UCSD research report

I’m not concerned that the UCSD research was less than favorable as some others might be, after all, it is looking out into the future and if a concern, provides a glimpse of what to keep an eye on.

Likewise, looking back, the research report could be taken as simply a barometer of what could happen if no improvements or new technologies evolve. For example, the HDD would have hit the proverbial brick wall also known as the super parametric barrier many years ago if new recording methods and materials had not been deployed including a shift to perpendicular recording, something that was recently added to tape.

Tomorrows SSDs and storage mediums will still be based on nand flash including SLC, MLC, eMLC along with other variants not to mention phased change memory (PCM) and other possible contenders.

Todays SSDs have shifted from being DRAM based with HDD or even flash-based persistent backing storage to nand flash-based, both SLC and MLC with enhanced or enterprise MLC appearing. Likewise the density of SSDs continue to increase meaning more data packed into the same die or footprint, more dies stacked in a chip package to boost capacity while decreasing cost. However what is also happening is behind the scenes which is a big differentiator with SSDs and that is the quality of some firmware and low-level page management at the flash translation layer (FTL). Hence they saying that anybody with a soldering iron and ability to pull together off the shelves FTLs and packaging can create some form of an SSD. How effective a product will be is based on the intelligence and robustness of the combination of the dies, FTL, controller and associated firmware and device drivers along with other packaging options plus the testing, validation and verification they undergo.

Various packaging options and where SSD can be deployed
Various SSD locations, types, packaging and usage scenario options

Good SSD vendors and solution providers I believe will be able to discuss your concerns around endurance, duty cycles, data integrity and other related topics to set up confidence with current and future issues, granted you may have to go under NDA to gain that insight. On the other hand, those who feel threatened or not able or interested in addressing or demonstrating confidence for the long haul will be more likely to dismiss studies, research, reports, opinions or discussions that dig deeper into creating confidence via understanding of how things work so that customers can more fully leverage those technologies.

Some will view and use reports such as the one from UCSD as a club or weapon against SSD and in particular against nand flash to help their cause or campaign while others will use it to stimulate controversy and page hit views. My reason for bringing up the topic and discussion it to stimulate thinking and help increase awareness and confidence in technologies such as SSD near and long-term. Regardless of if your view is that SSD will replace HDD, or that they will continue to coexist as tiered storage mediums into the future, gaining confidence in the technologies along with when, where and how to use them are important steps in shifting from industry adoption to customer deployment.

What say you?

Is SSD the best thing and you are dumb or foolish if you do not embrace it totally or a fan, pundit cheerleader view?

Or is SSD great when and where used in the right place so embrace it?

How will SSD continue to evolve including nand and other types of memories?

Are you comfortable with SSD as a long term data storage medium, or for today, its simply a good way to discuss performance bottlenecks?

On the other hand, is SSD interesting, however you are not comfortable or have confidence with the technology, yet you want to learn more, in other words a skeptics view?

Or perhaps the true cynic view which is that SSD are nothing but the latest buzzword bandwagon fad technology?

IT and storage economics 101, supply and demand

In my 2012 (and 2013) industry trends and perspectives predictions I mentioned that some storage systems vendors who managed their costs could benefit from the current Hard Disk Drive (HDD) shortage. Most in the industry would say that is saying what they have said, however I have an alternate scenario. My scenario is that for vendors who already manage good (or great) margins on their HDD sales and who can manage their costs including inventories stand to make even more margin. There is a popular myth that there is no money or margin in HDD or for those who sell them which might be true for some.

Without going into any details, lets just say it is a popular myth just like saying that there is no money in hardware or that all software and people services are pure profit. Ok, lets leave sleeping dogs lay where rest (at least for now).

Why will some storage vendors make more margin off of HDD when everybody is supposed to be adopting or deploying solid state devices (SSD). Or Hybrid Hard Disk Drives (HHDD) in the case of workstation, desktop or laptops? Simple, SSD adoption (and deployment) is still growing and a lot of demand generator incentives available. Likewise HDD demand continues to be strong and with supplies affected, economics 101 says that some will raise their prices, manage their expenses, make more profits which can be used to help fund or stimulate increased SSD or other initiatives.

Storage, IT and general Economics 101

Economics 101 or basics introduces the concept of supply and demand along with revenue minus costs = profits or margin. If there is no demand yet a supply of a product exists then techniques such as discounting, bundling or other forms of adding value to incentivize customers to make a purchase. Bundling can include offering some other product, service or offering that could be as simple as an extended warranty to motivate sellers. Beyond discounts, coupons, two for one, future buying credits, gift cards or memberships for frequent buyers (or flyers) are other forms of stimulating sales activity.

Likewise if there is a supply or competition for a given market of a product or alternative, vendors or those selling the products including value added resellers (VARS) may sacrifice margin (profits) to meet revenue as well as unit shipped (e.g. expand their customer and installed base footprint) goals.

Currently in the IT industry and specifically around data storage even with increased and growing adoption and demand deployment around SSD, there is also a large supply in different categories. For example there are several fabrication facilities (FABs) that produce the silicon dies (e.g. chips) that form nand flash SSD memories including Intel, Micron, the joint Intel and Micron Fab (IMF) and Samsung. Even with continued strong demand growth, the various FABs seem to have enough capacity at least for now. Likewise manufactures of SSD drive form factor products with SAS or SATA interfaces for attaching to existing servers, storage or appliances including Intel, Micron, Samsung, Seagate, STEC and SANdisk among others seem to be able to meet demand. Even PCIe SSD card vendors have come under pressure of supply and demand. For example the high flying startup FusionIO recently saw its margins affected due to competition which includes Adaptec, LSI, Texas Memory Systems (TMS) and soon EMC among others. In the SSD appliance and storage system space there are even more vendors with what amounts to about one every month or so coming out of stealth. Needless to say there will be some shakeout in the not so distant future.

On the other hand, if there is a demand however limited supply, assuming that the market will support it, prices can be increased from what discounts had applied. Assuming that costs are kept inline any subsequent increase in average selling price (ASP) minus costs should result in higher margins.

Another variation is if there is strong demand and shortage of supply such as what is occurring with hard disk drives (HDD) due to recent flooding in Thailand, not only prices increase, there can also be changes to warranties or other services and incentives. Note some of HDD manufactures such as Western Digital were more affected by the flooding than Seagate. Likewise the Thailand flooding was not limited to just HDD having also affected other electronic chip and component suppliers. Even though HDDs have been declared dead by many in the SSD camps along with their supporters, record number of HDDs are produced every year. Note that economics 101 also tells us that even though more devices are produced and sold, that may not show a profit based on their cost and price. Like the CPU processor chips produced by AMD, Broadcom, IBM and Intel among others that are high volume, with varying margins, the HDD and nand flash SSD market is also high volume with different margins.

As an example, Seagate recently announced strong profits due to a number of factors even though enterprise drive supply and shipments were down while desktop drives were up. Given that many industry pundits have proclaimed a disaster for those involved with HDDs due to the shortage, they forgot about economics 101 (supply and demand). Sure marketing 101 says that HDDs are dead and if there is a shortage then more people will buy SSDs however that also assumes that people are a) ready to buy more SSDs (e.g. demand) and b) vendors or manufactures have supply and c) that those same vendors or manufactures are willing to give up margin while reducing costs to boost profits.

Note that costs typically include selling, general and administrative, cost of goods, manufacturing, transportation and shipping, insurance, research and development among others. If it has been awhile since you looked at one, take a few minutes sometime to look at public companies and their quarterly securities exchange commission (SEC) financial filings. Those public filing documents are a treasure trove of information for those who sift through them and where many reporters, analysts and researchers find information for what they are working or speculating on. These documents show total sales, costs, profits and losses among other things. Something that vendors may not show in these public filings which means you have to look or read between the lines or get the information elsewhere is how many units were actually shipped or the ASP to get an idea of the amount of discounting that is occurring. Likewise sales and marketing expenses often get lumped into or under general selling and administration (SGA). A fun or interesting metric is to look at the percentage of SGA dollars spent per revenue and profits.

What I find interesting is to get an estimate of what it is costing an organization to do or sustain a given level of revenue and margin. For example, while some larger vendors may seem to spend more on selling and marketing, on a percentage basis, they can easily be out spent by smaller startups. Granted the larger vendor may be spending more actually dollars however those are spread out over a larger sales and revenue basis.

What does this all mean?

Look at multiple metrics that have both a future trend or forecast as well as trailing or historical perspective view. Look at both percentages as well as dollar amounts as well as both revenue and margin while keeping units or number of devices (or copies) sold also into perspective. For example its interesting to know if a vendors sales were down 10% (or up) quarter over quarter, or versus the same quarter a year ago or year over year. It is also interesting to keep the margin in perspective along with SGA costs in addition to cost of product acquired for sale. Also important is to get a gauge of if sales were down, yet margins are up, how many devices or copies were sold to get a gauge on expanding footprint which could also be a sign of future annuity (follow up sales opportunities). What Im watching is over the next couple of quarters is to see how some vendors leverage the Thailand flooding and HDD as well as other electronic component supply shortages to meet demand by managing discounts, costs and other items that contribute to enhanced margins.

Rest assured there is a lot more to IT and storage economics, including advanced topics such as Return on Investment (ROI) or Return on Innovation (The new ROI) and Total Cost of Ownership (TCO) among others that maybe we will discuss in the future.

Ok, nuff fun for now, lets get back to work.

AWS (Amazon) storage gateway, first, second and third impressions

Amazon Web Services (AWS) today announced the beta of their new storage gateway functionality that enables access of Amazon S3 (Simple Storage Services) from your different applications using an appliance installed in your data center site. With this beta launch, Amazon joins other startup vendors who are providing standalone gateway appliance products (e.g. Nasuni etc) along with those who have disappeared from the market (e.g. Cirtas). In addition to gateway vendors, there are also those with cloud access added to their software tools such as (e.g. Jungle Disk that access both Rack space and Amazon S3 along with Commvault Simpana Cloud connector among others). There are also vendors that have joined cloud access gateways as part of their storage systems such as TwinStrata among others. Even EMC (and here) has gotten into the game adding qualified cloud access support to some of their products.

What is a cloud storage gateway?

Before going further, lets take a step back and address what for some may be a fundemental quesiton of what is a cloud storage gateway?

Cloud services such as storage are accessed via some type of network, either the public Internet or a private connection. The type of cloud service being accessed (figure 1) will decide what is needed. For example, some services can be accessed using a standard Web browser, while others must plug-in or add-on modules. Some cloud services may need downloading an application, agent, or other tool for accessing the cloud service or resources, while others give an on-site or on-premisess appliance or gateway.

Generic cloud access example via Cloud and Virtual Data Storage Networking (CRC Press)
Figure 1: Accessing and using clouds (From Cloud and Virtual Data Storage Networking (CRC Press))

Cloud access software and gateways or appliances are used for making cloud storage accessible to local applications. The gateways, as well as enabling cloud access, provide replication, snapshots, and other storage services functionality. Cloud access gateways or server-based software include tools from BAE, Citrix, Gladinet, Mezeo, Nasuni, Openstack, Twinstrata among others. In addition to cloud gateway appliances or cloud points of presence (cpops), access to public services is also supported via various software tools. Many data protection tools including backup/restore, archiving, replication, and other applications have added (or are planning to add) support for access to various public services such as Amazon, Goggle, Iron Mountain, Microsoft, Nirvanix, or Rack space among several others.

Some of the tools have added native support for one or more of the cloud services leveraging various applicaiotn programming interfaces (APIs), while other tools or applications rely on third-party access gateway appliances or a combination of native and appliances. Another option for accessing cloud resources is to use tools (Figure 2) supplied by the service provider, which may be their own, from a third-party partner, or open source, as well as using their APIs to customize your own tools.

Generic cloud access example via Cloud and Virtual Data Storage Networking (CRC Press)
Figure 2: Cloud access tools (From Cloud and Virtual Data Storage Networking (CRC Press))

For example, I can use my Amazon S3 or Rackspace storage accounts using their web and other provided tools for basic functionality. However, for doing backups and restores, I use the tools provided by the service provider, which then deal with two different cloud storage services. The tool presents an interface for defining what to back up, protect, and restore, as well as enabling shared (public or private) storage devices and network drives. In addition to providing an interface (Figure 2), the tool also speaks specific API and protocols of the different services, including PUT (create or update a container), POST (update header or Meta data), LIST (retrieve information), HEAD (metadata information access), GET (retrieve data from a container), and DELETE (remove container) functions. Note that the real behavior and API functionality will vary by service provider. The importance of mentioning the above example is that when you look at some cloud storage services providers, you will see mention of PUT, POST, LIST, HEAD, GET, and DELETE operations as well as services such as capacity and availability. Some services will include an unlimited number of operations, while others will have fees for doing updates, listing, or retrieving your data in addition to  basic storage fees. By being aware of cloud primitive functions such as PUT or POST and GET or LIST, you can have a better idea of what they are used for as well as how they play into evaluating different services, pricing, and services plans.

Depending on the type of cloud service, various protocols or interfaces may be used, including iSCSI, NAS NFS, HTTP or HTTPs, FTP, REST, SOAP, and Bit Torrent, and APIs and PaaS mechanisms including .NET or SQL database commands, in addition to XM, JSON, or other formatted data. VMs can be moved to a cloud service using file transfer tools or upload capabilities of the provider. For example, a VM such as a VMDK or VHD  is prepared locally in your environment and then uploaded to a cloud provider for execution. Cloud services may give an access program or utility that allows you to configure when, where, and how data will be protected, similar to other backup or archive tools.

Some traditional backup or archive tools have added direct or via third party support for accessing IaaS cloud storage services such as Amazon, Rack space, and others. Third-party access appliance or gateways enable existing tools to read and write data to a cloud environment by presenting a standard interface such as NAS (NFS and/or CIFS) or iSCSI (Block) that gets mapped to the back-end cloud service format. For example, if you subscribe to Amazon S3, storage is allocated as objects and various tools are used to use or utilize. The cloud access software or appliance understands how to communicate with the IaaS  storage APIs and abstracts those from how they are used. Access software tools or gateways, in addition to translating or mapping between cloud APIs, formats your applications including security with encryption, bandwidth optimization, and data footprint reduction such as compression and de-duplication. Other functionality include reporting, management tools that support various interfaces, protocols and standards including SNMP or SNIA, Storage Management Initiative Specification (SMIS), and Cloud Data Management Initiative (CDMI).

First impression: Interesting, good move Amazon, I was ready to install and start testing it today

The good news here is that Amazon is taking steps to make it easier for your existing applications and IT environments to use and leverage clouds for private and hybrid adoption models with both an Amazon branded and managed services, technology and associated tools.

This means leveraging your existing Amazon accounts to simplify procurement, management, ongoing billing as well as leveraging their infrastructure. As a standalone gateway appliance (e.g. it does not have to be bundled as part of a specific backup, archive, replication or other data management tool), the idea is that you can insert the technology into your existing data center between your servers and storage to begin sending a copy of data off to Amazon S3. In addition to sending data to S3, the integrated functionality with other AWS services should make it easier to integrated with Elastic Cloud Compute (EC2) and Elastic Block storage (EBS) capabilities including snapshots for data protection.

Thus my first impression of AWS storage gateway at a high level view is good and interesting resulting in looking a bit deeper resulting in a second impression.

Second impression: Hmm, what does it really do and require, time to slow down and do more home work

Digging deeper and going through the various publicly available material (note can only comment or discuss on what is announced or publicly available) results in a second impression of wanting and needing to dig deeper based on some of caveats. Now granted and in fairness to Amazon, this is of course a beta release and hence while on first impression it can be easy to miss the notice that it is in fact a beta so keep in mind things can and hopefully will change.

Pricing aside, which means as with any cloud or managed storage service, you will want to do a cost analysis model just as you would for procuring physical storage, look into the cost of monthly gateway fee along with its associated physical service running VMware ESXi configuration that you will need to supply. Chances are that if you are an average sized SMB, you have a physical machine (PM) laying around that you can throw a copy of ESXi on to if you dont already have room for some more VMs on an existing one.

You will also need to assess the costs for using the S3 storage including space capacity charges, access and other fees as well as charges for doing snapshots or using other functionality. Again these are not unique to Amazon or their cloud gateway and should be best practices for any service or solution that you are considering. Amazon makes it easy by the way to see their base pricing for different tiers of availability, geographic locations and optional fees.

Speaking of accessing the cloud, and cloud conversations, you will also want to keep in mind what your networking bandwidth service requirements will be to move data to Amazon that might not already be doing so.

Another thing to consider with the AWS storage gateway is that it does not replace your local storage (that is unless you move your applications to Amazon EC2 and EBS), rather makes a copy of what every you save locally to a remote Amazon S3 storage pool. This can be good for high availability (HA), business continuance (BC), disaster recovery (DR) and compliance among other data management needs. However in your cost model you also need to keep in mind that you are not replacing your local storage, you are adding to it via the cloud which should be seen as complimenting and enhancing your private now to be hybrid environment.

 

Walking the cloud data protection talk

FWIW, I leverage a similar model where I use a service (Jungle Disk) where critical copies of my data get sent to that service which in turn places copies at Rack space (Jungledisks parent) and Amazon S3. What data goes to where depends on different policies that I have established. I also have local backup copies as well as master gold disaster copy stored in a secure offsite location. The idea is that when needed, I can get a good copy restored from my cloud providers quickly regardless of where I am if the local copy is not good. On the other hand, experience has already demonstrated that without sufficient network bandwidth services, if I need to bring back 100s of GBytes or TBytes of data quickly, Im going to be better off bring back onsite my master gold copy, then applying fewer, smaller updates from the cloud service. In other words, the technologies compliment each other.

By the way, a lesson learned here is that once my first copy is made which have data footprint reduction (DFR) techniques applied (e.g. compress, de dupe, optimized, etc), later copies occur very fast. However subsequent restores of those large files or volumes also takes longer to retrieve from the cloud vs. sending up changed versions. Thus be aware of backup vs. restore times, something of which will apply to any cloud provider and can be mitigated by appliances that do local caching. However also keep in mind that if a disaster occurs, will your local appliance be affected and its cache rendered useless.

Getting back to AWS storage gateway and my second impression is that at first it sounded great.

However then I realized it only supports iSCSI and FWIW, nothing wrong with iSCSI, I like it and recommend using it where applicable, even though Im not using it. I would like to have seen a NAS (either NFS and/or CIFS) support for a gateway making it easier for in my scenario different applications, servers and systems to use and leverage the AWS services, something that I can do with my other gateways provided via different software tools. Granted for those environments that already are using iSCSI for your servers that will be using AWS storage gateway, then this is a non issue while for others it is a consideration including cost (time) to factor in to prepare your environment for using the ability.

Depending on the amount of storage you have in your environment, the next item that caught my eye may or may not be an issue that the iSCSI gateway supports up to 1TB volumes and up to 12 of them hence a largest capacity of 12TB under management. This can be gotten around by using multiple gateways however the increased complexity balanced to the benefit the functionality is something to consider.

Third impression: Dig deeper, learn more, address various questions

This leads up to my third impression the need to dig deeper into what AWS storage gateway can and cannot do for various environments. I can see where it can be a fit for some environments while for others at least in its beta version will be a non starter. In the meantime, do your homework, look around at other options which ironically by having Amazon launching a gateway service may reinvigorate the market place of some of the standalone or embedded cloud gateway solution providers.

What is needed for using AWS storage gateway

In addition to having an S3 account, you will need to acquire for a monthly fee the storage gateway appliance which is software installed into a VMware ESXi hypervisor virtual machine (VM). The requirements are VMware ESXi hypervisor (v4.1) on a physical machine (PM) with at least 7.5GB of RAM and four (4) virtual processors assigned to the appliance VM along with 75GB of disk space for the Open Virtual Alliance (OVA) image installation and data. You will also need to have an proper sized network connection to Amazon. You will also need iSCSI initiators on either Windows server 2008, Windows 7 or Red Hat Enterprise Linux.

Note that the AWS storage gateway beta is optimized for block write sizes greater than 4Kbytes and warns that smaller IO sizes can cause overhead resulting in lost storage space. This is a consideration for systems that have not yet changed your file systems and volumes to use the larger allocation sizes.

Some closing thoughts, tips and comments:

  • Congratulations to Amazon for introducing and launching an AWS branded storage gateway.
  • Amazon brings trust the value of trust to a cloud relationship.
  • Initially I was excited about the idea of using a gateway that any of may systems could use my S3 storage pools with vs. using gateway access functions that are part of different tools such as my backup software or via Amazon web tools. Likewise I was excited by the idea of having an easy to install and use gateway that would allow me to grow in a cost effective way.
  • Keep in mind that this solution or at least in its beta version DOES NOT replace your existing iSCSI based storage needs, instead it compliments what you already have.
  • I hope Amazon listens carefully to what they customers and prospects want vs. need to evolve the functionality.
  • This announcement should reinvigorate some of the cloud appliance vendors as well as those who have embedded functionality to Amazon and other providers.
  • Keep bandwidth services and optimization in mind both for sending data as well as for when retrieving during a disaster or small file restore.
  • In concept, the AWS storage gateway is not all that different than appliances that do snapshots and other local and remote data protection such as those from Actifio, EMC (Recoverpoint), Falconstor or dedicated gateways such as those from Nasuni among others.
  • Here is a link to added AWS storage gateways frequently asked questions (FAQs).
  • If the AWS were available with a NAS interface, I would probably be activating it this afternoon even with some of their other requirements and cost aside.
  • Im still formulating my fourth impression which is going to take some time, perhaps if I can get Amazon to help sell more of my books so that I can get some money to afford to test the entire solution leveraging my existing S3, EC2 and EBS accounts I might do so in the future, otherwise for now, will continue to research.

Learn more abut cloud based data protection, data footprint reduction, cloud gateways, access and management, check out my book Cloud and Virtual Data Storage Networking (CRC Press) which is of course available on Amazon Kindle as well as via hard cover print copy also available at Amazon.com.

Ok, nuff said for now, I need to get back to some other things while thinking about this all some more.

My Server and Storage IO holiday break projects

Happy new years!

Following up from a flurry of posts in the closing days of 2011 including industry trends perspective predictions for 2012 and 2013, top blog posts from 2011, top all time posts, along with a couple of other items here and here, its time to get back to 2012 activity. Also if you missed it, here is the Fall (December) 2011 StorageIO news letter.

Actually I have been busy working on some other projects the past several weeks most of which are NDA so not much else can be said about them, however there are some other things I’m working on that will show themselves in the weeks and months to come. Here is a link to a webinar and live chat that I did the first week of January on CDP (Continuous Data Protection) and how it can be applied to many different environments.

But lets take a step back for a moment and let me share with you some of the things I did or started during the holiday break between christmas and the new years.

Like many others, I found time to relax and get away from normal work activities during the recent holiday season.

However like many of you that may also be techniques or geeks or wanna be geeks at heart, I could not get away from server, storage, IO, networking, data protection, video and other things completely. I used some time to discuss a few projects that I had wanted to do or that I had started before the holidays and here is a synopsis.

Increased storage capacity on a DVR by about 5x In order to get this to work, I modified a 3.5 enclosure with a power supply to accept a 2.5 1.5TB SATA HDD with an eSATA connection, the easy part was then attaching it to the external eSATA port on my DVR. The hard part was then waiting for the DVR to reconfigure and start recording information again. Also as part of upgrading the external storage on the DVR was to get the media share option to do more than basic things leveraging audio and video real-time trans coding using the Tversity software along with various codecs on a media server.

Another project involved upgrading a 500GB HHDD to a 750GB HHDD and did some testing Shortly before the holidays I received a new 750GB Seagate Momentus XT II HHDD to compare to my exiting 500GB previous generation model. I have been using the 750GB HHDD for over a month now and it is amazing to see so much space in a laptop that also has good performance. Some follow-up activities are to go back and analyze some performance data that I collected before and after the upgrade. This includes both workload simulation of reads, writes, random, sequential of different IO size as well as comparing Windows startup and shutdown speed and impact to build on what I did last summer (see this post). More on these in the not so distance future.

Speaking of clouds, I had a chance to do some more testing with my Amazon EC2 and EBS accounts in addition to cleaning up my S3 pool in addition to my other cloud backup and storage providers accounts. This also involved refining some data protection backup/restore and archive frequency and retention settings. In addition to refinements for cloud based backup, I’m also in the process of transitioning from Imation Odyssey Removable Hard Disk Drives (RHDD) too much larger capacity 2.5 portable RHDDs that are used for offsite bulk copies. Part of the migration includes seeing that end of year master or gold backups and archives were made and safely secured elsewhere in addition to having data sent to the cloud.

Another project involved doing some more testing and simulations with my SSD along with more windows boot and shutdown tests mentioned above. More on these results in a future post.

Sometime (actually not very much) was also spent adding some new shares to my Iomega IX4 NAS which is filling up so I also did some more research on what I will upgrade or replace it with. While Iomega has been great (knock on wood), Synology is also looking interesting as a future solution however keeping my options open for now. Right now I’m leaning towards keeping the IX4 and adding another NAS filer using the two for different purposes.

Some other server, storage and IO projects also included upgrading some networking components, and to finish decommissioning old drives making them secure for safe disposal when the time comes.

I also was able to spend time on non tech items including outside enjoying the nice weather, cutting up some fallen trees and roasting them on a bonfire among other things.

Ok, nuff said for now, time to get back to work.

2012 industry trends perspectives and commentary (predictions)

2011 is almost over, so its wrap up time of the year as well as getting ready for 2012.

Here is a link to a post of the top 25 new posts that appeared on StorageIOblog in 2011.

As a companion to the above, here is a link to the all time top 25 posts from StorageIOblog.

Looking back, here is a post about industry trends, thoughts and perspective predictions for 2010 and 2011 (preview 2012 and 2013 thoughts and perspectives here).

Im still finalizing my 2012 and 2013 predictions and perspectives which is a work in progress, however here is a synopsis:

  • Addressing storage woes at the source: Time to start treating the source of data management and protection including backup challenges instead of or in addition to addressing downstream target destination topics.
  • Big data and big bandwidth meet big backup: 2011 was a buzz with big data and big bandwidth so 2012 will see realization that big backup needs to be addressed. Also in 2012 there will be continued realization that many have been doing big data and big bandwidth thus also big backups for many years if not decades before the current big buzzword became popular.
  • Little data does not get left out of the discussion even though younger brother big data gets all of the press and praise. Little data may not be the shining diva it once was, however the revenue annuity stream will keep many software, tools, server and storage vendors afloat while customers continue to rely on the little data darling to run their business.
  • Cloud confusion finds clarity on the horizon: Granted there will be plenty of more cloud fud and hype, cloud washing and cleaning going around, however 2012 and beyond will also find organizations realizing where and how to use different types of clouds (public, private, hybrid) too meet various needs from SaaS and AaaS to PaaS to IaaS and other variations of XaaS. Part of the clarification that will help remove the confusion will be that there are many different types of cloud architectures, products, stacks, solutions, services and products to address various needs. Another part of the clarification will be discussion of what needs to be added to clouds to make them more viable for both new, as well as old or existing applications. This means organizations will determine what they need to do to move their existing applications to some form of a cloud model while understanding how clouds coexist and compliment what they are currently doing. Cloud conversations will also shift from low cost or for free focus expanding to discussions around value, trust, quality of service (QoS), SLOs, SLAs, security, reliability and related themes.

Industry Trends and Perspectives

  • Cloud and virtualization stack battles: The golden rule of virtualization and clouds is that who ever controls the management and software stacks controls the gold. Hence, watch for more positioning around management and enablement stacks as well as solutions to see who gains control of the gold.
  • Data protection modernization: Building off of first point above, data protection modernization the past several years has been focused on treating the symptoms of downstream problems at the target or destination. This has involved swapping out or moving media around, applying data footprint reduction (DFR) techniques downstream to give near term tactical relief as has been the cause with backup, restore, BC and DR for many years. Now the focus will start to expand to how to address the source of the problem with is an expanding data footprint upstream or at the source using different data footprint reduction tools and techniques. This also means using different metrics including keeping performance and response time in perspective as part of reduction rates vs. ratios while leveraging different techniques and tools from the data footprint reduction tool box. In other words, its time to stop swapping out media like changing tires that keep going flat on a car, find and fix the problem, change the way data is protected (and when) to cut the impact down stream. This will not happen overnight, however with virtualization and cloud activities underway, now is a good time to start modernizing data protection.
  • End to End (E2E) management tools: Continue focus around E2E tools and capabilities to gain situational awareness across different technology layers.
  • FCoE and Fibre Channel continue to mature: One sure sign that Fibre Channel over Ethernet (FCoE) is continuing to evolve, mature and gain initial traction is the increase in activity declaring it dead or dumb or similar things. FCoE is still in its infancy while Fibre Channel (FC) is in the process of transitioning to 16Gb with a roadmap that will enable it to continue for many more years. As FCoE continues to ramp up over next several years (remember, FC took several years to get where it is today), continued FC enhancements will give options for those wishing to stick with it while gaining confidence with FCoE, iSCSI, SAS and NAS.
  • Hard drive shortages drive revenues and profits: Some have declared that the recent HDD shortages due to Thailand flooding will cause Solid State Devices (SSD) using flash memory to dramatically grow in adoption and deployment. I think that both single level cell (SLC) and multi level cell (MLC) flash SSDs will continue to grow in deployments counted in units shipped as well as revenues and hopefully also margin or profits. However I also think that with the HDD shortage and continued demand, vendors will use the opportunity to stabilize some of their pricing meaning less discounting while managing the inventory which should mean more margin or profits in a quarter or too. What will be interesting to watch will be if SSD vendors drop the margin in an effort to increase units shipped and deployed to show market revenue and adoption growth while HDD margins rise.

Industry Trends and Perspectives

  • QoS, SLA/SLOs part of cloud conversations: Low cost or cost avoidance will continue to be the focus of some cloud conversations. However with metrics and measurements to make informed decisions, discussions will expand to QoS, SLO, SLAs, security, mean time to restore or return information, privacy, trust and value also enter into the picture. In other words, clouds are growing up and maturing for some, while their existing capabilities become discovered by others.
  • Clouds are a shared responsibility model: The cloud blame game when something goes wrong will continue, however there will also be a realization that as with any technology or tool, there is a shared responsibility. This means that customers accept responsibility for how they will use a tool, technologies or service, the provider assumes responsibility, and both parties have a collective responsibility.
  • Return on innovation is the new ROI: For years, no make that decades a popular buzz term is return on investment the companion of total cost of ownership. Both ROI and TCO as you know and like (or hate) will continue to be used, however for situations that are difficult to monitize, a new variation exists. That new variation is return on innovation which is the measure of intangible benefits derived from how hard products are used to derive value for or of soft products and services delivered.
  • Solid State Devices (SSD) confidence: One of the barriers to flash SSD adoption has been cost per capacity with another being confidence in reliability and data consistency over time (aka duty cycle wear and tear). Many enterprise class solutions have used single level cell (SLC) flash SSD which has better endurance, duty cycle or wear handing capabilities however that benefit comes at the cost of a higher price per capacity. Consequently vendors are pushing multi level cell (MLC) flash SSD that reduces the cost per capacity, however needs extra controller and firmware functionality to manage the wear leaving and duty cycle. In some ways, MLC flash is to SSD memory what SATA high-capacity desktop drives were to HDDs in the enterprise storage space about 8 to 9 years ago. What I mean by that is that more cost high performance disk drives were the norm, then lower cost higher capacity SATA drives appeared resulting in enhancements to make them more enterprise capable while boosting the confidence of customers to use the technology. Same thing is happening with flash SSD in that SLC is more expensive and for many has a higher confidence, while MLC is lower cost, higher capacity and gaining the enhancements to take on a role for flash SSD similar to what high-capacity SATA did in the HDD space. In addition to confidence with SSD, new packaging variations will continue to evolve as well.
  • Virtualization beyond consolidation: The current wave of consolidation of desktop using VDI, server and storage aggregation will continue, however a trend that has grown for a couple of years now that will take more prominence in 2012 and 2013 is realization that not everything can be consolidated, however many things can be virtualized. This means for some applications the focus will not be how many VMs to run per PM, rather, how a PM can be more effectively used to boost performance and agility for some applications during part of the day, while being used for other things at different times. For example a high performance database that normally would not be consolidated would be virtualized to enable agility for maintenance, BC, DR load balancing and placed on a fast PM with lots of fast memory, CPU and IO capabilities dedicated to it. However during off hours when little to no database activity is occurring, then other VMs would be moved onto that PM then moved off before the next busy cycle.

Industry Trends and Perspectives

  • Will applications be ready to leverage cloud: Some applications and functionality can more easily be moved to cloud environments vs. others. A question that organizations will start to ask is what prevents their applications or business functionality from going to or using cloud resources in addition to asking cloud providers what new capabilities will they extend to support old environments.
  • Zombie list grows: More items will be declared dead meaning that they are either still alive, or have reached stability to the point where some want to see them dead so that their preferred technology or topic can take root.
  • Some other topics and trends include continued growing awareness that metrics and measurements matter for cloud, virtualization, data and storage networking. This also means a growing awareness that there are more metrics that matter for storage than cost per GByte or Tbyte that include IOPS, latency or response time, bandwidth, IO size, random and sequential along with availability. 2012 and 2013 will see continued respect being given to NAS at both the high end as well as low end of the market from enterprise down to consumer space. Speaking of consumer and SOHO (Small Office Home Office), now that SMB has generally been given respect or at least attention by many vendors, the new frontier will be to move further down market to the lower end of the SMB which is SOHO, just above consumer space. Of course some vendors have already closed the gap (or at least on paper, power point, web ex or you tube video) from consumer to enterprise. Of course Buzzword bingo will continue to be a popular game.
  • Oh, btw, DevOps will also appear in your vocabulary if it has not already.
