What industry pundits love and loathe about data storage

Drew Robb has a good article about what IT industry pundits including vendors, analysts, and advisors loath including comments from myself.

In the article Drew asks: What do you really love about storage and what are your pet peeves?

One of my comments and perspectives is that I like Hybrid Hard Disk Drives (HHDDs) in addition to traditional Hard Disk Drives (HDD) along with Solid State Devices (SSDs). As much as I like HHDDs, I also believe that with any technology, they are not the best solution for everything, however they can also be used in many ways than being seen. Here is the fifth installment of a series on HHDDs that I have done since June 2010 when I received my first HHDD a Seagate Momentus XT. You can read the other installments of my momentus moments here, here, here and here.

Molly Rector VP of marketing at tape summit resources vendor Spectra Logic mentioned that what she does not like is companies that base their business plan on patent law trolling. I would have expected something different along the lines of countering or correcting people that say tape sucks, tape is dead, or that tape is the cause problem of anything wrong with storage thus clearing the air or putting up a fight that tape summit resources. Go figure…

Another of my comments involved clouds of which there are plenty of conversations taking place. I do like clouds (I even recently wrote a book involving them) however Im a fan of using them where applicable to coexist and enhance other IT resources. Dont be scared of clouds, however be ready, do your homework, listen, learn, do proof of concepts to decide best practices, when, where, what and how to use them.

Speaking of clouds, click here to read about who is responsible for cloud data loss and cast your vote, along with viewing what do you think about IT clouds in general here.

Mike Karp (aka twitter @storagewonk ) an analyst with Ptak Noel mentions that midrange environments dont get respect from big (or even startup) vendors.

I would take that a step further by saying compared to six or so years ago, SMB are getting night and day better respect along with attention by most vendors, however what is lacking is respect of the SOHO sector (e.g. lower end of SMB down to or just above consumer).

Granted some that have traditional sold into those sectors such as server vendors including Dell and HP get it or at least see the potential along with traditional enterprise vendor EMC via its Iomega . Yet I still see many vendors including startups in general discounting, shrugging off or sneering at the SOHO space similar to those who dissed or did not respect the SMB space several years ago. Similar to the SMB space, SOHO requires different products, packaging, pricing and routes to market via channel or etail mechanisms which means change for some vendors. Those vendors who embraced the SMB and realized what needed to change to adapt to those markets will also stand to do better with the SOHO.

Here is the reason that I think SOHO needs respect.

Simple, SOHOs grow up to become SMBs, SMBs grow up to become SMEs, SMEs grow up to become enterprises and not to mention that the amount of data being generated, moved, processed and stored continues to grow. The net result is that SMBs along with SOHO storage demands will continue to grow and for those vendors who can adjust to support those markets will also stand to gain new customers that in turn can become plans for other solution offerings.

Cloud conversations

Not surprising Eran Farajun of Asigra which has been doing cloud backups decades before they were known as clouds loves backup (and restores). However I am surprised that Eran did not jump on the its time to modernize and re architect data protection theme. Oh well, will have to have a chat with Eran on that sometime.

What was surprising were comments from Panzura who has a good distributed (e.g. read also cloud) file system that can be used for various things including online reference data. Panzura has a solution that normally I would not even think about in the context of being pulled into a Datadomain or dedupe appliance type discussion (e.g tape sucks or other similar themes). So it is odd that they are playing to the tape sucks camp and theme vs. playing to where the technology can really shine which IMHO is in the global, distributed, scale out and cloud file system space. Oh well, I guess you go with what you know or has worked in the past to get some attention.

Molly Rector of Spectra also mentioned that she likes High Performance Computing, surprised that she did not throw in high productivity computing as well in conjunction with big data, big bandwidth, green, dedupe, power, disk, tape and related buzzword bingo terms.

Also there are some comments from myself about cost cutting.

While I see the need for organizations to cut costs during tough economic times, Im not a fan of simply cutting cost for the sake of cost cutting as opposed to finding and removing complexity that in turn remove costs of doing work. In other words, Im a fan of finding and removing waste, becoming more effective and productive along with removing the cost of doing a particular piece of work. This in the end meets the aim of bean counters to cut costs, however can be done in a way that does not degrade service levels or customer service experience. For example instead of looking to cut backup costs, do you know where the real costs of doing data protection exist (hint swapping out media is treating the symptoms) and if so, what can be done to streamline those from the source of the problem downstream to the target (e.g. media or medium). In other words, redesign, review, modernize how data protection is done, leverage data footprint reduction (DFR) techniques including archive, compression, consolidation, data management, dedupe and other technologies in effective and creative ways, after all, return on innovation is the new ROI.

The blame game: Does cloud storage result in data loss?

I recently came across a piece by Carl Brooks over at IT Tech News Daily that caught my eye, title was Cloud Storage Often Results in Data Loss. The piece has an effective title (good for search engine: SEO optimization) as it stood out from many others I saw on that particular day.

Industry Trend: Cloud storage

What caught my eye on Carls piece is that it reads as if the facts based on a quick survey point to clouds resulting in data loss, as opposed to being an opinion that some cloud usage can result in data loss.

Data loss

My opinion is that if not used properly including ignoring best practices, any form of data storage medium or media 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 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.

Data loss

Technology failure: Not if, rather when and how to decrease impact
Any technology regardless of what it is or who it is from along with its architecture design and implementation can fail. It is not if, rather when and how gracefully along with what safeguards to decrease the impact, in addition to containing or isolating faults differentiates various products or solutions. How they automatically repair and self heal to keep running or support accessibility and maintain data integrity are important as is how those options are used. Granted a failure may not be technology related per say, rather something associated with human intervention, configuration, change management (or lack thereof) along with accidental or intentional activities.

Walking the talk
I have used public cloud storage services for several years including SaaS and AaaS as well as IaaS (See more XaaS here) and knock on wood, have not lost any data yet, loss of access sure, however not data being lost.

I follow my advice and best practices when selecting cloud providers looking for good value, service level agreements (SLAs) and service level objectives (SLOs) over low cost or for free services.

In the several years of using cloud based storage and services there has been some loss of access, however no loss of data. Those service disruptions or loss of access to data and services ranged from a few minutes to a little over an hour. In those scenarios, if I could not have waited for cloud storage to become accessible, I could have accessed a local copy if it were available.

Had a major disruption occurred where it would have been several days before I could gain access to that information, or if it were actually lost, I have a data insurance policy. That data insurance policy is part of my business continuance (BC) and disaster recovery (DR) strategy. My BC and DR strategy is a multi layered approach combining local, offline and offsite as along with online cloud data protection and archiving.

Assuming my cloud storage service could get data back to a given point (RPO) in a given amount of time (RTO), I have some options. One option is to wait for the service or information to become available again assuming a local copy is no longer valid or available. Another option is to start restoration from a master gold copy and then roll forward changes from the cloud services as that information becomes available. In other words, I am using cloud storage as another resource that is for both protecting what is local, as well as complimenting how I locally protect things.

Minimize or cut data loss or loss of access
Anything important should be protected locally and remotely meaning leveraging cloud and a master or gold backup copy.

To cut the cost of protecting information, I also leverage archives, which mean not all data gets protected the same. Important data is protected more often reducing RPO exposure and speed up RTO during restoration. Other data that is not as important is protected, however on a different frequency with other retention cycles, in other words, tiered data protection. By implementing tiered data protection, best practices, and various technologies including data footprint reduction (DFR) such as archive, compression, dedupe in addition to local disk to disk (D2D), disk to disk to cloud (D2D2C), along with routine copies to offline media (removable HDDs or RHDDs) that go offsite,  Im able to stretch my data protection budget further. Not only is my data protection budget stretched further, I have more options to speed up RTO and better detail for recovery and enhanced RPOs.

If you are looking to avoid losing data, or loss of access, it is a simple equation in no particular order:

  • Strategy and design
  • Best practices and processes
  • Various technologies
  • Quality products
  • Robust service delivery
  • Configuration and implementation
  • SLO and SLA management metrics
  • People skill set and knowledge
  • Usage guidelines or terms of service (ToS)

Unfortunately, clouds like other technologies or solutions get a bad reputation or blamed when something goes wrong. Sometimes it is the technology or service that fails, other times it is a combination of errors that resulted in loss of access or lost data. With clouds as has been the case with other storage mediums and systems in the past, when something goes wrong and if it has been hyped, chances are it will become a target for blame or finger pointing vs. determining what went wrong so that it does not occur again. For example cloud storage has been hyped as easy to use, don’t worry, just put your data there, you can get out of the business of managing storage as the cloud will do that magically for you behind the scenes.

The reality is that while cloud storage solutions can offload functions, someone is still responsible for making decisions on its usage and configuration that impact availability. What separates various providers is their ability to design in best practices, isolate and contain faults quickly, have resiliency integrated as part of a solution along with various SLAs aligned to what the service level you are expecting in an easy to use manner.

Does that mean the more you pay the more reliable and resilient a solution should be?
No, not necessarily, as there can still be risks including how the solution is used.

Does that mean low cost or for free solutions have the most risk?
No, not necessarily as it comes down to how you use or design around those options. In other words, while cloud storage services remove or mask complexity, it still comes down to how you are going to use a given service.

Shared responsibility for cloud (and non cloud) storage data protection
Anything important enough that you cannot afford to lose, or have quick access to should be protected in different locations and on various mediums. In other words, balance your risk. Cloud storage service provider toned to take responsibility to meet service expectations for a given SLA and SLOs that you agree to pay for (unless free).

As the customer you have the responsibility of following best practices supplied by the service provider including reading the ToS. Part of the responsibility as a customer or consumer is to understand what are the ToS, SLA and SLOs for a given level of service that you are using. As a customer or consumer, this means doing your homework to be ready as a smart educated buyer or consumer of cloud storage services.

If you are a vendor or value added reseller (VAR), your opportunity is to help customers with the acquisition process to make informed decision. For VARs and solution providers, this can mean up selling customers to a higher level of service by making them aware of the risk and reward benefits as opposed to focus on cost. After all, if a order taker at McDonalds can ask Would you like to super size your order, why cant you as a vendor or solution provider also have a value oriented up sell message.

Poll:  Who is responsible for cloud storage data loss?

Taking action, what you should (or not) do
Dont be scared of clouds, however do your homework, be ready, look before you leap and follow best practices. Look into the service level agreements (SLAs) associated with a given cloud storage product or service. Follow best practices about how you or someone else will protect what data is put into the cloud.

For critical data or information, consider having a copy of that data in the cloud as well as at or in another place, which could be in a different cloud or local or offsite and offline. Keep in mind the theme for critical information and data is not if, rather when so what can be done to decrease the risk or impact of something happening, in other words, be ready.

Data put into the cloud can be lost, or, loss of access to it can occur for some amount of time just as happens with using non cloud storage such as tape, disk or ssd. What impacts or minimizes your risk of using traditional local or remote as well as cloud storage are the best practices, how configured, protected, secured and managed. Another consideration is the type and quality of the storage product or cloud service can have a big impact. Sure, a quality product or service can fail; however, you can also design and configure to decrease those impacts.

Wrap up
Bottom line, do not be scared of cloud storage, however be ready, do your homework, review best practices, understand benefits and caveats, risk and reward. For those who want to learn more about cloud storage (public, private and hybrid) along with data protection, data management, data footprint reduction among other related topics and best practices, I happen to know of some good resources. Those resources in addition to the links provided above are titled Cloud and Virtual Data Storage Networking (CRC Press) that you can learn more about here as well as find at Amazon among other venues. Also, check out Enterprise Systems Backup and Recovery: A Corporate Insurance Policy by Preston De Guise (aka twitter @backupbear ) which is a great resource for protecting data.

Supporting IT growth demand during economic uncertain times

Doing more with less, doing more with what you have or reducing cost have been the mantra for the past several years now.

Does that mean as a trend, they are being adopted as the new way of doing business, or simply a cycle or temporary situation?

Reality is that many if not most IT organizations are and will remain under pressure to stretch their budgets further for the immediate future. Over the past year or two some organizations saw increases in their budgets however also increased demand while others saw budgets fixed or reduced while having to support growth. On the other hand, there is no such thing as an information recession with more data being generated, moved, processed, stored and retained for longer periods of time.

Industry trend: No such thing as a data recession

Something has to give as shown in the following figure which is that on one curve there is continued demand and growth, while another curve shows need to reduce costs while another reflects the importance of maintaining or enhancing service level objectives (SLOs) and quality of service (QoS).

Enable growth while removing complexity and cost without compromising service levels

One way to reduce costs is to inhibit growth while another is to support growth by sacrificing QoS including performance, response time or availability as a result of over consolidation, excessive utilization or instability as a result of stretching resources to far. Where innovation comes into play is finding and fixing problems vs. moving or masking them or treating symptoms vs. the real issue and challenge. Innovation also comes into play by identifying both near term tactical as well as longer term strategic means of taking complexity and cost out of service delivery and the resources needed to support them. For example determining the different resources and processes involved in delivering an email box of a given size and reliability. Another being supporting a virtual machine (VM) with a given performance and capacity capability. Yet another scenario is a file share or home directory of a specific size and availability. By streamlining work flows, leveraging automation and other tools to enforce polices as well as adopting new best practices complexity and thereby costs can be reduced. The net rest is a lower cost to provide a given service to a specific level which when multiplied out over many users or instances, results in cost savings however also productivity gains.

The above is all good and well for longer term strategic and where you want to go or get to, however what can be done right now today?

Here are a few tips to do more with what you have while supporting growth demands

If you have service level agreements (SLAs) and SLOs as part of your service category, review with your users as to what they need vs. what they would like to have. What you may find is that your users want or expect a given level of service, yet would be happy and ok with moving to a cloud service that had lower SLO and SLA expectations if lower cost. The previous scenario would be an indicator that you users want and thus you give them a higher level of service, yet their requirements are actually lower than what is expected. On the other hand if you do not have SLOs and SLAs aligned with cost for the services then set them up and review customer or client expectations, needs vs. wants on a regular basis. You might find out that you can stretch your budget by delivering a lower (or higher) class of services to meet different users requirements than what was assumed to be the case. In the case of supporting a better class of service, if you can use an SSD enabled solution to reduce latency or wait times and boost productivity, more transactions or page views or revenue per hour, that could prompt a client to request that capability to meet their business needs.

Reduce your data footprint impact in order to support growth using the ABCDs of data footprint reduction (DFR), that is Archive (email, file, database), Backup modernization, Compression and consolidation, Data management and dedupe, storage tiering among other techniques.

Storage, server virtualization and optimization using capacity consolidation where practical and IO consolidation to fast storage and SSD where possible. Also review storage configuration including RAID and allocation to identity if any relatively easy changes can improve performance, availability, capacity and energy impact.

Investigate available upgrades and enhancements to your existing hardware, software and services that can be applied to provide breathing room within current budgets while evaluating new technologies.

Find and fix problems vs. chasing false positives that provide near term relief only to have the real issue reappear. Maximize your budgets by identifying where people time and other resources are being spent due to processes, work flows, technology configuration complexity or bottlenecks and address those.

Enhance and leverage existing management measurements to gain more insight along with implementing new metrics for End to End (E2E) situational awareness of your environment which will enable effective decision making. For example you may be told to move some function to the cloud as it will be cheaper, yet if you do not have metrics to indicate one way or the other, how can that be an informed decision? If you have metrics that show your cost for the same service being moved to a cloud or managed service provider as well as QoS, SLO, SLA, RTO, RPO and other TLAs, then you can make informed decisions. That decision may still be to move functions to a cloud or other service even if in fact it is more expensive compared to what you can provide it for in order that your resources can be directed to supporting other important internal functions.

Look for ways to reduce cost of a service delivered as opposed to simply cutting costs. They sound like one and the same, however if you have metrics and measurements providing situational awareness to know what the cost of a service is, you can also then look at how to streamline those services, remove complexity, reduce workflow, leverage automation there by removing cost. The goal is the same, however how you go about removing cost can have an impact on your return on innovation not to mention customer satisfaction.

Also be an informed shopper, have a forecast or plan on what you will need and when, along with what you must have (core requirements) vs. what you would like to have or want. When looking at options, balance what is needed and then if you can get what you want or would like for little or no extra cost if they add value or enable other initiatives. Part of being an informed shopper is having support of the business to be able to procure what you want or need which means aligning technology resources and their cost to delivery of business functions and services.

What you need vs. what you want
In a recent interview with the associated press (AP) the reporter wanted to know my comments about spending vs. saving during economic tough times (you can read the story here). Basically my comments were to spend within your means by identifying what you need vs. what you want, what is required to keep the business running or improve productivity and remove cost as opposed to acquiring nice to have things that can wait. Sure I would like to have a new 85 to 120" 3D monitor for my workstation that could double as a TV, however I do not need or require it.

On the other hand, I recently upgraded an existing workstation adding a Hybrid Hard Disk Drive (HHDD) and some additional memory, about a $200USD investment that is already paying for itself via increased productivity. That is instead of enjoying a cup of dunkin donut coffee while waiting for some tasks to complete on that system, Im able to get more done in a given amount of time boosting productivity.

For IT environments this means looking at expenditures to determine what is needed or required to keep things running while supporting near term strategic and tactical initiatives or pet projects.

For vendors and vars, if things have not been a challenge yet, now they will need to refine their messages to show more value, return on innovation (ROI) in terms of how to help their customers or prospects stretch resources (budgets, people, skill sets, products, services, licenses, power and cooling, floor space) further to support growth, while removing costs without compromising on service delivery. This also means a shift in thinking of short term or tactical cost cutting to longer term strategic approaches of reducing costs to deliver a service or resources.

Industry trend: People plus data are aging and living longer

Lets face it, people and information are living longer and thus there are more of each along with a strong interdependency by both.

People living and data being retained longer should not be a surprise, take a step back and look at the bigger picture. There is no such thing as an information recession with more data being generated, processed, moved and stored for longer periods of time not to mention that a data object is also getting larger.

Industry trend and performance

By data objects getting larger, think about a digital photo taken on a typical camera ten years ago which whose resolution was lower and thus its file size would have been measured in kilo bytes (thousands). Today megapixel resolutions are common from cell phones, smart phones, PDAs and even larger with more robust digital and high definition (HD) still and video cameras. This means that a photo of the same object that resulted in a file of hundreds of Kbytes ten years ago would be measured in Megabytes today. With three dimensional (3D) cameras appearing along with higher resolution, you do not need to be a rocket scientist or industry pundit to figure out what that growth trend trajectory looks like.

However it is not just the size of the data that is getting larger, there are also more instances along with copies of those files, photos, videos and other objects being created, stored and retained. Similar to data, there are more people now than ten years ago and some of those have also grown larger, or at least around the waistline. This means that more people are creating and relying on larger amounts of information being available or accessible when and where needed. As people grow older, the amount of data that they generate will naturally increase as will the information that they consume and rely upon.

Where things get interesting is that looking back in history, that is more than ten or even a hundred years, the trend is that there are more people, they are living longer, and they are generating larger amounts of data that is taking on new value or meaning. Heck you can even go back from hundreds to thousands of years and see early forms of data archiving and storage with drawings on walls of caves or other venues. I Wonder if had the cost (and ease of use) to store and keep data had been lower back than would there have been more information saved? Or was it a case of being too difficult to use the then state of art data and information storage medium combined with limited capacities so they simply ran out of storage and retention mediums (e.g. walls and ceilings)?

Lets come back to the current for a moment which is another trend of data that in the past would have been kept offline or best case near line due to cost and limits or constraints are finding their way online either in public or private venues (or clouds if you prefer).

Thus the trend of expanding data life cycles with some types of data being kept online or readily accessible as its value is discovered.

Evolving data life cycle and access patterns

Here is an easy test, think of something that you may have googled or searched for a year or two ago that either could not be found or was very difficult to find. Now take that same search or topic query and see if anything appears and if it does, how many instances of it appear. Now make a note to do the same test again in a year or even six months and compare the results.

Now back to the future however with an eye to the past and things get even more interesting in that some researchers are saying that in centuries to come, we should expect to see more people not only living into their hundreds, however even longer. This follows the trend of the average life expectancy of people continues to increase over decades and centuries.

What if people start to live hundreds of years or even longer, what about the information they will generate and rely upon and its later life cycle or span?

More information and data

Here is a link to a post where a researcher sees that very far down the road, people could live to be a thousand years old which brings up the question, what about all the data they generate and rely upon during their lifetime.

Ok, now back to the 21st century and it is safe to say that there will be more data and information to process, move, store and keep for longer periods of time in a cost effective way. This means applying data footprint reduction (DFR) such as archiving, backup and data protection modernization, compression, consolidation where possible, dedupe and data management including deletion where applicable along with other techniques and technologies combined with best practices.

Will you out live your data, or will your data survive you?

These are among other things to ponder while you enjoy your summer (northern hemisphere) vacation sitting on a beach or pool side enjoying a cool beverage perhaps gazing at the passing clouds reflecting on all things great and small.

Clouds: Dont be scared, however look before you leap and be prepared

Ok, nuff said for now.

Cloud and Virtual Data Storage Networking

For those who have read any of my previous posts, seen some of my articles, news letters, videos, pod casts, web casts or in person appearances you may have heard that I have a new book coming out this summer.

Here in the northern hemisphere its summer (well technically the solstice is just around the corner) and in Minnesota the ice (from the winter) is off the lakes and rivers. Granted, there is some ice floating that fell out of coolers for keeping beverages cool. This means that it is also fishing (and catching) season on the Scenic St. Croix River.

Karen of Arcola catches first fish of 2011 season, St. Croix river, stripe bassGreg showing his first catch of the 2011 season, St. Croix walleye aka Walter or Wanda

FTC disclosures (and for fun): Karenofarcola is wearing a StorageIO baseball cap and Im wearing a cap from a vendor marketing person who sent several as they too enjoy fishing and boating. Funny thing about the cap, all of the river rats and fishing people think it is from the people who make rod reels instead of solutions that go around tape and disk reels. Note, if you feel compelled to send me baseball caps, send at least a pair so there is a backup, standby, spare or extra one for a guest. The mustang survival jacket that Im wearing with the Seadoo logo is something I bought myself. I did get a discount however since there was a Seadoo logo on it and I used to have Seadoo jet boats. Btw, that was some disclosure fun and humor!

Ok, enough of the fun stuff, lets get back to the main theme of this post.

My new book which is the third in a series of solo projects including Resilient Storage Networks: Designing Flexible Scalable Data Infrastructures (Elsevier) and The Green and Virtual Data Center (CRC).

While the official launch and general availability will be later in the summer, following are some links and related content to give you advance information about the new book.

Using Removable Hard Disk Drives (RHDDs)

Removable hard disk drives (RHDD) are a form of removable media which includes magnetic tape that address many common use cases. Usage scenarios include enabling bulk data portability for larger environments or for D2D backup where the media needs to be physically moved offsite for small and mid sized environments. RHDDs include among others those from Imation such as the Odyssey (which is what I use) and the Prostor RDX (OEMed by Imation and others). RHDD, tape along with other forms of portable media including those that use flash by being removable and portable presumable should have some extra packaging protection to safeguard against static shock in addition to supporting encryption capabilities.

Compared to disks including RHDD, tape for most and particularly larger environments should have an overall lower media cost for parking, preserving and when needed serving inactive or archived data (e.g. the changing roll of tape from day to back up to archive). Of course your real costs will vary by use in addition to how combined with data footprint reduction and other technologies.

A big benefit of RHDDs is that they are random meaning data can be searched and found quickly vs. tape media which has great sequential or streaming capabilities if you have a system that can support that ability. The other benefit of RHDD is that depending on their implementation, they should plug and play with your systems appearing as disk without any extra drivers or configuration or software tools making for ease of use. Being removable they can be used for portability such as sending data to a cloud or MSP as part of an initial bulk copy, or sending data offset or taking home as part of an offsite backup, data protection or BC/DR strategy as well as being used for archiving. The warning with RHDD is their cost per TByte will generally be higher than compared to tape as well as having to have a docking station or specific drive interface depending on specific product and configuration.

RHDD are a great compliment to traditional fixed or non removable disk, Hybrid Hard Disk Drive (HHDD) and Solid State Device (SSD) based storage as well as coexist with cloud or MSP backup and archive solutions. The smaller the environment the more affordable using RHDD become vs. tape for backup and archive operations or when portability is required. Even if using a cloud or managed service provider (MSP) backup provider, network bandwidth costs, availability or performance may limit the amount of data that can be moved in a cost effective way. For example placing an archive and gold or master copy of your static data on a RHDD that may be kept on site in a safe off-site place and then sending data that is routinely changed to the cloud or MSP provider (think full local and offsite plus partial full and incremental in the cloud).

By leveraging archiving and data footprint reduction (DFR) techniques including dedupe and compression, you can stretch your budget by sending less data to cloud or MSP services while using removable media for data protection. You would be surprised how many TBytes of data can be kept in a safe deposit box. For my own business, I have used RHDDs for several years to keep gold master copies as well as archives offsite as part of a disk to disk (D2D) or D2D2RHDD strategy. The data protection strategy is also complimented by sending active data to a cloud backup MSP (encrypted of course). It might be belt and suspenders, however it is also eating my own dog food practicing what I talk about and the approach has proven itself a few times.

Tape talk time (tape summit and tape is alive, for some)

Welcome to the tape summit resources and tape summit resources micro site with links for those who are interested in magnetic tape for backup, archive, BC, DR, big and little data

For being a declared dead or zombie technology (here, here or here) tape remains very much alive however its role is changing. There is no disputing that hard disk drives (HDDs) are continuing to expand their role for data protection including backup/restore, BC and DR where tape has been used  for decades.

What is also occurring is that tapes role is changing from day to day backup to that of longer term data preservation including archiving with more data stored on tape today than in past history at a lower cost. In fact the continued reduced cost per tape and improved capacity as well as utilization has worked against tape from a marketing competitive standpoint. For example if you look at a chart showing tape (media and drive) revenues you see a decline, similar to what was seen a couple of years ago for HDDs.

What is not shown on some charts are how many units (drives or media) shipped with more capacity for a given price (again what was reported for HDDs a few years ago) when net capacity had increased. Vendors of tape technology have also had a rather low profile particular for those with other technologies that have received more marketing resources (people, time, money). After all, if a product is on a plateau of productivity and profitability why spend time or effort on extensive marketing or promotion vs. directing resources to get new items into the market.

As a result, for those looking to make a case that tape is on the decline based on revenues to convince customers to move away from that technology should have a marketing freebie. Recently Oracle announced a new large capacity tape drive and media following on previous announcements of enhanced LTO roadmap and future 35TByte  tape capabilities announced January 2010 by Fujifilm and IBM.

For those who are interested following are some links to various topics including how SSD, HDD and tape can coexist complementing each other for different roles or functions. As to those who do not like tape, feel free to read if you like as there is also material on SSD, HDD, dedupe, cloud, data protection and other topics.

Some previous blog posts:

Here are some additional articles, commentary and reports pertaining to tape related topics:

Something tells me we will be hearing, reading or watching more about tape being alive in the months to come.

IBMs Storwize or wise Storage, the V7000 and DFR

A few months ago IBM bought a Data Footprint Reduction (DFR) technology company called Storwize (read more about DFR and Storwize Real time Compression here, here, here, here and here).

A couple of weeks ago IBM renamed the Storwize real time compression technology to surprise surprise, IBM real time compression (wow, wonder how lively that market focus research group study discussion was).

Subsequently IBM recycled the Storwize name in time to be used for the V7000 launch.

Now to be clear right up front, currently the V7000 does not include real time compression capabilities, however I would look for that and other forms of DFR techniques to appear on an increasing basis in IBM products in the future.

IBM has a diverse storage portfolio with good products some with longer legs than others to compete in the market. By long legs, that means both technology and marketability for enabling their direct as well as partners including distributors or vars to effectively compete with other vendors offerings.

The enablement capability of the V7000 will be to give IBM and their business partners a product that they will want go tell and sell to customers competing with Cisco, Dell, EMC, Fujitsu, HDS, HP, NEC, NetApp and Oracle among others.

What about XIV?

For those interested in XIV regardless of if you are a fan, nay sayer or simply an observer, here, here and here are some related posts to view if you like (as well as comment on).

Back to the V7000

A couple of common themes about the IBM V7000 are:

  • It appears to be a good product based on the SVC platform with many enhancements
  • Expanding the industry scope and focus awareness around Data Footprint Reduction (DFR)
  • Branding the storwize acquisition as real-time compression as part of their DFR portfolio
  • Confusion about using the Storwize name for a storage virtualization solution
  • Lack of Data Footprint Reduction (DFR) particularly real-time compression (aka Storwize)
  • Yet another IBM storage product adding to confusion around product positioning

Common questions that Im being asked about the IBM V7000 include among others:

  • Is the V7000 based on LSI, NetApp or other third party OEM technology?

    No, it is based on the IBM SVC code base along with an XIV like GUI and features from other IBM products.

  • Is the V7000 based on XIV?

    No, as mentioned above, the V7000 is based on the IBM SVC code base along with an XIV like GUI and features from other IBM products.

  • Does the V7000 have DFR such as dedupe or compression?

    No, not at this time other than what was previously available with the SVC.

  • Does this mean there will be a change or defocusing on or of other IBM storage products?

    IMHO I do not think so other than perhaps around XIV. If anything, I would expect IBM to start pushing the V7000 as well as the entire storage product portfolio more aggressively. Now there could be some defocusing on XIV or put a different way, putting all products on the same equal footing and let the customer determine what they want based on effective solution selling from IBM and their business partners.

  • What does this mean for XIV is that product no longer the featured or marquee product?

    IMHO XIV remains relevant for the time being. However, I also expect to be put on equal footprint with other IBM products or, if you prefer, other IBM products particularly the V7000 to be unleashed to compete with other external vendors solutions such as those from Cisco, Dell, EMC, Fujitsu, HDS, HP, NEC, NetApp and Oracle among others. Read more here, here and here about XIV remaining relevant.

  • Why would I not just buy an SVC and add storage to it?

    That is an option and strength of SVC to sit in front of different IBM storage products as well as those of third party competitors. However with the V7000 customers now have a turnkey storage solution to sell instead of a virtualization appliance.

  • Is this a reaction to EMC VPLEX, HDS VSP, HP SVSP or 3PAR, Oracle/Sun 7000?

    Perhaps it is, perhaps it is a reaction to XIV, and perhaps it is a realization that IBM has a lot of IP that could be combined into a solution to respond to a market need among many other scenarios. However, IBM has had a virtualization platform with a decent installed base in the form of SVC which happens to be at the heart of the V7000.

  • Does this mean IBM is jumping on the using off the shelf server instead of purpose built hardware for storage systems bandwagon like Oracle, HP and others are doing?

    If you are new to storage or IBM, it might appear that way, however, IBM has been shipping storage systems that are based on general purpose servers for a couple for a couple of decades now. Granted, some of those products are based on IBM Power PC (e.g. power platform) also used in their pSeries formerly known as the RS6000s. For example, the DS8000 series similar to its predecessors the ESS (aka Shark) and VSS before that have been based on the Power platform. Likewise, SVC has been based on general purpose processors since its inception.

    Likewise, while only generally deployed in two node pairs, the DS8000 is architected to scale into many more nodes that what has been shipped meaning that IBM has had clustered storage for some time, granted, some of their competitors will dispute that.

  • How does the V7000 stack up from a performance standpoint?

    Interestingly, IBM has traditionally been very good if not out front running public benchmarks and workload simulations ranging from SPC to TPC to SPEC to Microsoft ESRP among others for all of their storage systems except one (e.g. XIV). However true to traditional IBM systems and storage practices, just a couple of weeks after the V7000 launch, IBM has released the first wave of performance comparisons including SPC for the V7000 which can be seen here to compare with others.

  • What do I think of the V7000?

    Like other products both in the IBM storage portfolio or from other vendors, the V7000 has its place and in that place which needs to be further articulated by IBM, it has a bright future. I think that the V7000 for many environments particularly those that were looking at XIV will be a good IBM based solution as well as competitor to other solutions from Dell, EMC, HDS, HP, NetApp, Oracle as well as some smaller startups providers.

Comments, thoughts and perspectives:

IBM is part of a growing industry trend realizing that data footprint reduction (DFR) focus should expand the scope beyond backup and dedupe to span an entire organization using many different tools, techniques and best practices. These include archiving of databases, email, file systems for both compliance and non compliance purposes, backup/restore modernization or redesign, compression (real-time for online and post processing). In addition, DFR includes consolidation of storage capacity and performance (e.g. fast 15K SAS, caching or SSD), data management (including some data deletion where practical), data dedupe, space saving snapshots such as copy on write or redirect on write, thin provisioning as well as virtualization for both consolidation and enabling agility.

IBM has some great products, however too often with such a diverse product portfolio better navigation and messaging of what to use when, where and why is needed not to mention the confusion over the current product dejur.

As has been the case for the past couple of years, lets see how this all plays out in a year or so from now. Meanwhile cast your vote or see the results of others as to if XIV remains relevant. Likewise, join in on the new poll below as to if the V7000 is now relevant or not.

Note: As with the ongoing is XIV relevant polling (above), for the new is the V7000 relevant polling (below) you are free to vote early, vote often, vote for those who cannot or that care not to vote.

Re visiting if IBM XIV is still relevant with V7000

Over the past couple of years I routinely get asked what I think of XIV by fans as well as foes in addition to many curious or neutral onlookers including XIV competitors, other analysts, media, bloggers, consultants as well as IBM customers, prospects, vars and business partners. Consequently I have done some blog posts about my thoughts and perspectives.

Its time again for what has turned out to be the third annual perspective or thoughts around IBM XIV and if it is still relevant as a result of the recent IBM V7000 (excuse me, I meant to say IBM Storwize V7000) storage system launch.

For those wanting to take a step back in time, here is an initial thought perspective about IBM and XIV storage from 2008, as well as the 2009 revisiting of XIV relevance post and the latest V7000 companion post found here.

What is the IBM V7000?

Here is a link to a companion post pertaining to the IBM V7000 that you will want to have a look at.

In a nut shell, the V7000 is a new storage system with built in storage virtualization or virtual storage if you prefer that leverages IBM developed software from its San Volume Controller (SVC), DS8000 enterprise system and others.

Unlike the SVC which is a gateway or appliance head that virtualizes various IBM and third party storage systems providing data movement, migration, copy, replication, snapshot and other agility or abstraction capabilities, the V7000 is a turnkey integrated solution.

By being a turnkey solution, the V7000 combines the functionality of the SVC as a basis for adding other IBM technologies including a GUI management tool similar to that found on XIV along with dedicated attached storage (e.g. SAS disk drives including fast, high capacity as well as SSD).

In other words, for those customer or prospects who liked XIV because of its management GUI interface, you may like the V7000.

For those who liked the functionality capabilities of the SVC however needed it to be a turnkey solution, you might like the V7000.

For those of you who did not like or competed with the SVC in the past, well, you know what to do.

BTW, for those who knew of Storwize the Data Footprint Reduction (DFR) vendor with real time compression that IBM recently acquired and renamed IBM Real time Compression, the V7000 does not contain any real time compression (yet).

What are my thoughts and perspectives?

In addition to the comments in the companion post found here, right now Im of the mind set that XIV does not fade away quietly into the sunset or take a timeout at the IBM technology rest and recuperation resort located on the beautiful someday isle.

The reason I think XIV will remain somewhat relevant for some time, (time to be determined of course) is that IBM has expended over the past two and half years significant resources to promote it. Those resources have included marketing time, messaging space and in some instances perhaps inadvertinly at the expense of other IBM storage solutions. Simiarly, a lot of time, money and effort have gone into business partner outreach to establish and keep XIV relevant with those commuities who in turn have gone to their customers to tell and sell the XIV story to some customers who have bought it.

Consequently or as a result of all of that investment, I would be surprised if IBM were simply to walk away from XIV at least near term.

What I do see as happening including some early indicators is that the V7000 (along with other IBM products) now will be getting equal billing, resources and promotional support. Weather this means the XIV division finally being assimilated into the mainstream IBM fold and on equal footing with other IBM products, or, that other IBM products being brought up to an elevated position of XIV is subject to interpretation and your own perception.

I expect to continue to see IBM teams and subsequently their distributors, vars and other business partners get more excited talking about the V7000 along with other IBM solutions. For example, SONAS for bulk, clustered and scale out NAS, DS8000 for high end, GMAS and Information Archive platforms as well as N and DS3K/DS4K/DS5K not to mentiuon the TS/TL backup and archive target platforms along with associated Tivoli software. Also, lets not forget about SVC among other IBM solutions including of course, XIV.

I would also not be surprised if some of the diehard XIV loyalist (e.g. sales and marketing reps that were faithful members of Moshe Yani army who appears to be MIA at IBM) pack up their bags and leave the IBM storage SANdbox in virtual protest. That is, refusing to be assimilated into the general IBM storage pool and thus leaving for Greener IT pastures elsewhere. Some will stick around discovering the opportunities associated with selling a broader more diverse product portfolio into their target accounts where they have spent time and resources to establish relationships or getting thier proverbial foot in the door.

Consequently, I think XIV remains somewhat relevant for now given all of the resources that IBM poured into it and relationships that their partner ecosystem also spent on establishing with the installed customer base.

However, I do think that the V7000 despite some confusion (here and here) around its recycled Storwize name that is built around the field proven SVC and other IBM technology has some legs. Those legs of the V7000 are both from a technology standpoint as well as a means to get the entire IBM systems and storage group energized to go out and compete with their primary nemesis (e.g. Dell, EMC, HP, HDS, NetApp and Oracle among others).

As has been the case for the past couple of years, lets see how this all plays out in a year or so from now. Meanwhile cast your vote or see the results of others as to if XIV remains relevant. Likewise, join in on the new poll below as to if the V7000 is now relevant or not.

Note: As with the ongoing is XIV relevant polling (above), for the new is the V7000 relevant polling (below) you are free to vote early, vote often, vote for those who cannot or that care not to vote.

Have VTLs or VxLs become Zombies, Declared dead yet still alive?

Have you heard or read the reports and speculation that VTLs (Virtual Tape Libraries) are dead?

It seems that in IT the all to popular trend is to declare something dead so that your new product or technology can have a chance of making it in to the market or perhaps seen in a better light.

Sometimes this approach works to temporary freeze the market until common sense and clarity returns to the market or until something else fun to talk about comes along and in other cases, the messages can fall on deft ears.

The approach of declaring something dead tends to play well for those who like shiny new toys (SNT) or new shiny toys (NST) and being on the popular, cool trendy bandwagon.

Not surprisingly, while some actual IT customers can fall into the SNT or NST syndrome, its often the broader industry including media, bloggers, analysts, consultants and other self proclaimed or anointed pundits as well as vendors who latch on to the declare it dead movement. After all, who wants to talk about something that is old, boring and already being sold to paying customers who are using it. Now this is not a bad thing as we need a balance of up and coming challengers to keep the status quo challenged, likewise we need a balance of the new to avoid death grips on the old and what is working.

Likewise, many IT customers particularly larger ones tend to be very risk averse and conservative with their budgets protecting their investments thus they may only go leading bleeding edge if there is a dual redundant blood bank with a backup on hot standby (thats some HA humor BTW).

Another reason that declaring items dead in support of SNT and NST is that while many of the commonly declared dead items are on the proverbial plateau of productivity for IT customers, that also can mean that they are on the plateau of profitability for the vendors.

However, not all good things last and at sometime, there is the need to transition from the old to the new and this is where things like virtualization including virtual tape libraries or virtual disk libraries or virtual storage library or what ever you want to call a VxL (more on what a VxL is in a moment) can come into play.

I realize that for some, particularly those who like to grasp on to SNT, NST and ride the dead pool bandwagons this will probably appear as snarky or cynical which is fine, after all, for some, you should be laughing to the bank and if not, you may in fact be missing out on an opportunity for playing in the dead pool marketing game.

Now back to VxL.

In the case of VTLs, for some it is the T word that bothers them, you know T as in Tape which is not a SNT or NST in an age where SSD has supposedly killed the disk drive which allegedly terminated tape (yeah right). Sure tape is not being used as much for backup as it has in the past with its role shifting to that of longer term retention, something that it is well suited for.

For tape fans (or cynics) you can read more here, here and here. However there is still a large amount of backup/restore along with other data protection or preservation (e.g. archiving) processing (software tools, processes, procedures, skill sets, management tools) that still expects to see tape.

Hence this is where VTLs or VxLs come into play leveraging virtualization in an Life Beyond Consolidation (and here) scenario providing abstraction, transparency, agility and emulation and IMHO are still very much alive and evolving.

Ok, for those who do not like or believe in or of its continued existence and evolving role, substitute the T (tape) with X and you get a VxL. That is, plug in what ever X word that makes you happy or marketable or a Shiny New TLA. For example Virtual Disk Library, Virtual Storage Library, Virtual Backup Library, Virtual Compression Library, Virtual Dedupe Library, Virtual ILM Library, Virtual Archive Library, Virtual Cloud Library and so forth. Granted some VxLs only emulate tape and hence are VTLs while others support NAS and other protocols (or personalities) not to mention functionality ranging from replication, DFR as well as automated policy management.

However, keep in mind that if your preference is VTL, VxL or what ever other buzzword bingo name that you want to use or come up with, look at how virtualization in the form of abstraction, transparency and emulation can bridge the gap between the new (disk based data protection) combined with DFR (Data Footprint Reduction) and the old (existing backup/restore, archive or other management tools and processes.

Here are some additional links pertaining to VTLs (excuse me, VxLs):

  • Not to mention here, here, here, here or here.

Ok, nuff said.
