Data Proteciton for Virtual Environments at VMware VMworld

Storage I/O trends

Data protection for virtual environments including protecting virtual servers and virtual storage as well as using virtualization techniques to protect applications and data on non consolidated servers is gaining plenty of attention building on past, recent and this weeks as well as other forthcoming announcements during VMworld 2008 taking place now in Las Vegas. The last month or so has been busy with the usual analyst pre-briefing sessions for some of the items now announced as well as others that are still in the wings.

Here are a few links, one to a recent webcast (Industry Trends and Perspectives: Data Protection for Virtual Server Environments) along with another to an industry trends and perspective white paper titled “Data Protection Options for Virtual Servers”.

Now its time to get ready to travel off to New Orleans where I will be speaking about data protection and other related topics for virtual server and storage environments tonight at an event and then later this week in Chicago.

Ok, nuff said.

Why XIV is so important to IBMs storage business – Its Not About the Technology or Product!

Storage I/O trends

Ok, so I know I’m not taking a popular stance on this one from both camps, the IBMers and their faithful followers as well as the growing legion of XIV followers will take exception I’m sure.

Likewise, the nay sayers would argue why not take a real swing and knock the ball out of the park as if it were baseball batting practice. No, I’m going a different route as actually, either of the approaches would be too easy and have been pretty well addressed already.

The IBM XIV product that IBM acquired back in January 2008 is getting a lot of buzz (some good, some not so good) lately in the media and blog sphere (here and here which in turn lead to many others) as well as in various industry and customer discussions.

How ironic that the 2008 version of storage in an election year in the U.S. pits the IBM and XIV faithful in one camp and the nay sayers and competition in the other camps. To hear both camps go at it with points, counter points, mud-slinging and lipstick slurs should be of no surprise when it comes vendor?s points and counter points. In fact the only thing missing from some of the discussions or excuse me, debates is the impromptu appearance on-stage by either Senators Bidden, Clinton, McCain or Obama or Governor Palin to weigh in on the issues, after all, it is the 2008 edition of storage in an election year here in the United States.

Rather than jump on the bashing XIV bandwagon which about everyone in the industry is now doing except for, the proponents or, folks taking a step back looking at the bigger non-partisan picture like Steve Duplessie the genesis billionaire founder of ESG and probably the future owner of the New England Patriots (American) Football team whose valuation may have dripped enough for Steve to buy now that their start quarterback Tom Brady is out with a leg injury that will take longer to rebuild than all the RAID 6 configured 1 TByte SATA disk drives in 3PAR, Dell, EMC, HGST, HP, IBM, NetApp, Seagate, Sun and Western Digital as well as many other vendors test labs combined. As for the proponents or faithful, in the spirit of providing freedom of choice and flexible options, the cool-aid comes in both XIV orange as well as traditional IBM XIV blue, nuff said.

In my opinion, which is just that, an opinion, XIV is going to help and may have already done so for IBMs storage business not from the technical architecture or product capabilities or even in the number of units that IBM might eventually sell bundled or un-bundled. Rather, XIV is getting IBM exposure and coverage to be able to sit at the table with some re-invigorated spirit to tell the customer what IBM is doing and if they pay attention, in-between slide decks, grasp the orders for upgrades, expansion or new installs for the existing IBM storage product line, then continue on with their pitch until the customer asks to place another upgraded or expansion order, then quickly grab that order, then continue on with the presentation while touching lightly on the products IBM customers continue to buy and looking to upgrade including:

IBM disk
IBM tape – tape and virtual tape
DS8000 – Mainframe and open systems storage
DS5000 – New version of DS4000 to compete with new EMC CLARiiON CX4s
DS4000 ? aka the Array formerly known as the FastT
DS3000 – Entry level iSCSI, SAS and FC storage
NetApp based N-Series – For NAS windows CIFS and NFS file sharing
DR550 archiving solution
SAN Volume Controller-SVC

Not to mention other niche products such as the Data Direct Networks-DDN based DCS9550 or IBM developed DS6000 or recently acquired Diligent VTL and de-duping software.

IBM will be successful with XIV not by how many systems they sell or give away, oh, excuse me, add value to other solutions. How IBM should be gauging XIV success is based on increased sales of their other storage systems and associated software and networking technologies including the mainframe attachable DS8000, the new high performance midrange DS5000 that builds on the success of the DS4000, all of which should have both Brocade and Cisco salivating given their performance need for more Fibre Channel (and FICON for DS8000) 4GFC and 8GFC Fibre Channel ports, switches, adapters and directors. Then there is the netapp based N series for NAS and file serving to support unstructured data including Web and social networking.

If I were Brocade, Cisco, NetApp or any of the other many IBM suppliers, I would be putting solution bundles together certainly to ride the XIV wave, however have solution bundles ready to play to the collateral impact of all the other IBM storage products getting coverage. For example sure Brocade and Cisco will want to talk about more Fibre Channel and iSCSI switch ports for the XIV, however, also talk performance to be able to unleash the capabilities of the DS8000 and DS5000, or, file management tools for the N-Series as well as bundles around the archiving DR550 solution.

The N-Series NAS gateway that could be used in theory to dress up XIV and actually make it usable for NAS file serving, file sharing and Web 2.0 related applications or unstructured data. There is the IBM SAN Volume Controller-SVC that virtualizes almost everything except the kitchen sink which may be in a future release. There is the DR550 archiving and compliance platform that not only provides RAID 6 protected energy-efficient storage, it also supports movement of data to tape, now if IBM could get the story out on that solution which maybe in the course of talking about XIV, IBM DR550 might get discovered as well. Of course there are all the other backup, archiving, data protection management and associated tools that will get pick-up and traction as well.

You see even if IBM quadruples the XIV footprint of revenue installed in production systems with 400% growth rates year over year, never mind that the nay-sayers that would only be about 1/20 or 1/50th of what Dell/EqualLogic, or LeftHand via HP/Intel or even IBM xseries not to mention all the others using IBRIX, HP/PolyServe, Isilon, 3PAR, Panasas, Permabit, NEC and the list goes on with similar clustered solutions have already done.

The point is watch for up-tick even if only 10% on the installed DS8000 or DS5000 (new) or DS4000 or DS3000 or N-Series (NetApp) or DR550 (the archive appliance IBM should talk more about), or SVC or the TS series VTLs.

Even a 1% jump due to IBM folks getting out and in front of customers and business partners, a 10% jump on the installed based of somewhere around 40,000 DS8000 (and earlier ESS versions) is 4,000 new systems, on the combined DS5000/DS4000/DS3000 formerly known as FasT with combined footprint of over 100,000 systems in the field, 10% would be 10,000 new systems. Take the SVC, with about 3,000 instances (or about 11,000 clustered nodes), 10% would mean another new 300 instances and continue this sort of improvement across the rest of the line and IBM will have paid for not only XIV and Moshe?s (former EMCer and founded of XIV and now IBM fellow) retirement fund.

IBM may be laughing to the big blue bank even after having enough money to finally buy a clustered NAS file system for Web 2.0 and bulk storage such as IBRIX before someone else like Dell, EMC or HP gets their hands on it. So while everyone else continues to bash how bad XIV is performing. Whether this is a by design strategy or one that IBM can simply fall into, it could be brilliant if played out and well executed however only time will tell.

If those who want to rip on xiv really want to inflict damage, cease and ignore XIV for what it is or is not and find something else to talk about and rest assured, if there are other good stories, they will get covered and xiv will be ignored.

Instead of ripping on XIV, or listening to more XIV hype, I’m going fishing and maybe will come back with a fish story to rival the XIV hype, in the meantime, look I forward to seeing the IBM success for their storage business as a whole due to the opportunity for IBMers and their partners getting excited to go and talk about storage and being surprised by their customers giving them orders for other IBM products, that is unless the IBM revenue prevention department gets in the way. For example if IBMers or their partners in the excitement of the XIV moment forget to sell to customers what customers want, and will buy today or are ready to buy and grab the low hanging fruit (sales orders for upgrades and new sales) of current and recently enhanced products while trying to reprogram and re-condition customers to the XIV story.

Congratulations to IBM and their partners as well as OEM suppliers if they can collective pull the ruse off and actually stimulate total storage sales while XIV becomes a decoy and maybe even gets a few more installs and some revenue to help prop it up as a decoy.

Thank you Gartner for generating green awareness for my new book: The Green and Virtual Data Center!

Storage I/O trends

The other day Gartner issued a press release about their new findings that Users Are Becoming Increasingly Confused About the Issues and Solutions Surrounding Green IT.

This however what is missing from the Gartner report and action steps is to also say to read my new book “The Green and Virtual Data Center” (Auerbach).

However in all fairness, since Gartner has not yet seen it, I would seriously doubt that they would endorse anything other than one of their own publications.

Regardless, its great to see Gartner among others joining in and helping to transition industry awareness from Green Hype and help to close the Green gap (read more here and here) and begin addressing core issues that IT organizations can and are addressing to improve efficiency, address costs and enable sustainable business growth in an economic and environmental friendly way.

Thank you Gartner and let me know when and where you want a copy sent for a formal review and endorsement of my new book. Meanwhile, you can learn more at www.thegreenandvirtualdatacenter.com including a variety of green and related power, cooling, floor-space, environmental health and safety-EHS (PCFE) or green topics along with where to pre-order your advance copy from Amazon.com as well as other fine venues around the world.

Optical Storage Oppourtunities or Obsolence?

Storage I/O trends

Is Optical Storage still relevant?

Here’s a piece Alan Earls did for TechTarget on the subject.

I agree with that optical still has a role for preserving compliance and other fixed content data as doe’s magnetic tape. For example optical based CDs and DVDs are great archives for the music and videos that I purchased and transfer to my computer hard drive (or FLASH).

I will leave it to you to be the judge of if optical is still relevant or not.

Intelligent Power Management (IPM) and second generation MAID 2.0 on the rise

Storage I/O trends

In case you missed it today, Adaptec announced that they are the 1st vendor “This Week” to add support for Intelligent Power Management (IPM) to their storage systems. Adaptec joins a growing list of vendors who are deploying, or, who are program announcing some variation of IPM and second generation MAID 2.0 ability including support for different types of tiered disk drives including various combinations of Fibre Channel and SAS as well as SATA.

As a quick refresh, Massive or Monolithic Arrays of Idle or Inactive Disks (MAID) was popularized by 1st generation MAID vendor Copan who spins down disk drives to avoid energy usage. One of the challenges with 1st generation MAID is the poor performance by being able to only have at most 25% of the disk drives spinning at any time to transfer data when needed.

This is a balancing act between achieving energy avoidance and associated benefits vs. maintaining performance to move data when needed particularly for large restoration to support BC/DR or other purposes. Granted, 1st generation MAID systems like those from Copan while positioned as alternatives to high-performance disk storage systems to amplify potential energy savings on one hand, or, to put as an alternative to magnetic tape by providing random restore capability. The reality is that 1st generation MAID systems are finding their niche not for on-line primary or even on-line secondary storage, nor as a direct replacement for tape or even disk based libraries to support large-scale BC/DR, rather, in a sweet spot between secondary and near-line disk libraries and virtual tape libraries with a target application of very infrequently accessed of data.

Second generation MAID, aka MAID 2.0 is an evolution of the general technologies and capabilities extending functionality and flexibility while addressing quality of service (QoS), performance, availability, capacity and energy consumption using IPM also known as Adaptive Power Management (APM), dynamic bandwidth switching or scaling (DBS) among other names. The basic premise is to add flexibility building on 1st generation characteristics including data protection, resiliency and pro-active part or drive monitoring. Another basic premise of IPM. and MAID 2.0. solutions is to allow the performance and subsequent energy usage to vary, which is to cut the amount of performance and energy usage during in-active times, yet, when data needs to be accessed, to allow full performance without penalties for energy savings.

Second generation MAID solutions can be characterized by multiple power saving modes as well as flexible performance to adjust to changing workload and application needs. Another characteristic is the ability to work across different types of disk drives including Fibre Channel, SAS and SATA as opposed to only SATA drives found in 1st generation solutions as well as for the IPM or MAID 2.0 functionality to exist in a standard storage system or array instead of in a purpose-built dedicated storage system. Other capabilities include support for more granular power settings down to a RAID group or LUN level instead of across an entire array or storage system as well as support for different RAID levels among other features.

Examples of vendors who have either announced product or made statements of direction with regard to MAID 2.0 and IPM enabled storage systems include:

Adaptec (Today), Datadirect, EMC, Fujitsu, HDS, HGST (Hitachi Disk Drives), NEC, Nexsan, and Xyratex among others on a growing list of solutions.

For applications and data storage needs that need good performance and QoS over a range of changing usage conditions to balance good performance when needed to efficiently get work done to boost productivity, while saving or avoiding energy when little or no work needs to be done, take a look at current and emerging IPM and MAID 2.0 enabled storage systems as part of a tiered storage strategy to discuss power, cooling, floor-space and EHS (PCFE) related issues.

Closing the Green Gap – Green washing may be endangered, however addressing real green issues is here to stay

Storage I/O trends

Here’s a new article I wrote that just appeared over at Enterprise Storage Forum called Closing the Green Storage Gap.

Not all ‘green’ IT solutions or messages are created equal. Regardless of political views, the reality is that for business and IT sustainability, a focus on ecological issues and more importantly, their economic aspects cannot be ignored.

There are business benefits to using the most energy-efficient IT solutions to meet different data and application requirements. However, vendors are busy promoting ‘green’ stories and solutions that often miss where IT organization challenges and mandates exist. This article examines the growing gap between green messaging, or ‘Green Wash,’ and how to close the gap and enable IT organization issues to be addressed today in a way that sustains business growth in an economic and ecologically friendly way.

Have a read and a good weekend.

Green, Virtual, Servers, Storage and Networking 2008 Beijing Olympics

Storage I/O trends

How about those opening 2008 Beijing Olympic ceremonies on NBC last night?

If you were like me, I had my DVR capture the event while out enjoying the nice August evening with some friends doing some relaxing and fishing (we did catch and release fish!) on the scenic St. Croix river.

John Nelson with a small mouth bass caught and released on the St. Croix River During 2008 Beijing Olympics
Fishing while DVR records 2008 Olympics

Fishing while DVR records 2008 Olympics

A young bald eagle seen during fishing on the St. Croix river during opening of 2008 Olympic games
A young bald eagle seen during fishing while DVR records 2008 Olympics

The reason I bring up the Olympics, servers, storage, networking, virtualization and green topics are a couple of themes. One being all the news and content available to keep track of what is happening with the games taking place all of which is being stored on servers, storage and relying on networks to access the rich media and unstructured data via the web or traditional media. The 2008 summer games are also being described as the on-line and virtual olympics. The amount of storage being used to store digital data from the 2008 Olympics for later playback, which then gets recorded on DVRs if not watched in real-time is staggering as are the number of servers and networking capabilities being used. In addition to the video, audio, still photos, text and blogs, then there are the security cameras in Beijing generating massive amounts of digital data.

For those who track or keep an eye or ear open towards data and storage management, the amount of data that continues to grow and number of copies that get created should be a familiar theme. Of course, you would then have heard that the magic elixir is to simply de-dupe everything. That is reduce your data footprint by eliminating all of those extra copies however easier said then done, especially when a copy of the games is being transmitted and saved to millions of DVRs or other forms of data storage servers around the world.

For the time being, I prefer that my DVR support more usable storage capacity and real-time compression so that I can keep more copies of my favorite shows and of course the Olympics all in HDTV, which of course chews up storage space faster than a highly animated PowerPoint slide deck from your favorite vendors most recent, or, upcoming product announcements.

The other theme is in addition to being Olympic time, as well as late summer here in the northern hemisphere or winter for our friends in the summer hemisphere, its also pre-briefing and early product announcement time for the barrage of fall server, storage, networking, I/O, software, virtualization and green related solutions. So far, Im not sure if its the Olympics or what, however the bait line on the upcoming announcements and briefings include the tags “Industry First”, “Industry Unique”, “Only Vendor”, “Only Product”, “Revolutionary”, “First Vendor” or “First Product”, “Fastest”, “Largest”, “Greenest” among other interesting spins and twists that would even make an Olympic gymnast dizzy.

So enjoy the Olympic , keep those hard disk drives in your DVR cool while managing the usable capacity and watch for more gold medal attempts both from Beijing, as well as from your favorite IT vendors coming to a podium to you soon with their upcoming announcements, some of which may be award winning. Also check out www.greendatastorage.com which is now also pointed to by www.thegreenandvirtualdatacenter.com that has a new look and feel as well as some updated content with more on the way.

Brocade to Buy Foundry Networks – Prelude to Upcoming Converged Ethernet and FCoE Battle

Storage I/O trends

The emerging and maturing Fibre Channel over Ethernet (FCoE) and Converged Ethernet, aka Data Center Ethernet, Converged Enhanced Ethernet, Enterprise Ethernet among others marketing names activity is picking up. Today Brocade took a major step to shore up its already announced FCoE and converged Ethernet story which includes new directors and converged host bus adapters
by announcing intentions of buying

Ethernet high performance switching vendor Foundry Networks in a deal valued around $3B USD and some change. Not a bad deal for Foundry, some would say an expensive deal for Brocade, perhaps paying to much, however given some of the recent storage and networking related deals. For example IBM spending around $300M for a startup called XIV who claims to have shipped a few storage systems to a few customers, or, Dell spending about $1.3B to buy EqualLogic who had a few thousand customers (Could be the deal of the century for Dell compared to IBM and XIV, however time will tell), or EMC and some of its recent purchases like RSA, Avamar or bargains like WysDM, Mozy and Iomega not to mention Cisco having not been bashful about dropping some serious coin for standalone companies like Neuspeed (where are they now) for iSCSI as well as Andimao and more recently Nuovo. Regardless of if Mike Klayko (Brocade CEO) paid too much or not, he did what he had to do as part of his continuing activities to re-invent Brocade and leverage their core DNA and business focus of data infrastructures.

Brocade could probably have made a nice business for a few more years like some of the companies they have recently acquired tried to do including McData, CNT, INRANGE and so forth. However the reality is that sooner or later, they too (Brocade) would probably have been acquired by someone perhaps. With the acquisition of Foundry Networks, along with previous announcements for FCoE technologies and their existing products for NAS or file based storage management and iSCSI solutions, Brocade is signaling that they want to fight for survival as opposed to circle the wagons and guard their installed base and wheel house.

With the up-coming Converged Ethernet and FCoE battle royal shaping up to start in about 12 to 18 months, sooner for the early adopters who like to test and kick around technology early, or for those who want to go right to 10GbE today instead of 8Gb Fibre Channel, or, for those who like bleeding edge solutions. The reality even with recent proof of life plug-fest demos and claims of being ready for primetime, core Brocade customers particularly at the high-end of the market tend to be rather risk averse and cautions with their data infrastructure thus moving at a slower pace. For them, upgrading to 8Gb Fibre Channel may be the near term future while watching FCoE and converged Ethernet or converged enhanced Ethernet evolve and being transitioning in a couple of years. For these risk adverse type customers, bleeding edge technology means having a blood bank nearby and on call as downtime and disruption is not an option.

Rest assured, with Ciscopushing hard to stimulate the FCoE market and get people to skip 8Gb FC and switch over to 10GbE, there will be plenty more plug fest and proof of life demos, plenty of trash talking by both sides that will rival some of the best heavy weight match-ups.

Buyers beware, do your home work and if being an early adopter of FCoE and converged networks is right for you, with due diligence do some testing to see how everything really works in your environment from storage systems, to adapters, to switches, to protocol converters and gateways to management and diagnostic software. How does the whole ecosystem that matches your environment work for your scenario. If you are not comfortable with where the FCoE and converged Ethernet technologies and more importantly supporting ecosystem are at, take your time, monitor the situation as it unfolds over the next year or so leading up to the big battle royal between Brocade and Cisco.

Something that I think is interesting is that here we have Brocade and Cisco squaring off in a convergence battle between a general networking vendor (Cisco) and storage centric networking vendor (Brocade), both of whom have been built on organic growth as well as acquisitions. What?s even more interesting is that around 10 years ago back when Brocade was just getting started and Cisco was still trying to figure out Fibre Channel and iSCSI, 3COM had at the time the foresight to put together an alliance of Storage related partners to get into the then emerging SAN market place. The alliance was to include various storage vendors, switch and HBA as well as router or gateway vendors along with data and backup software vendors. Before the program could be officially launched, it was canceled just as all of the promotional material was about to be distributed due to poor finical health of 3COM. With a few exceptions, most of the participants in that early program, which was probably a year or two ahead of its time have either been bought or disappeared altogether. 3COM could have been a major force in a converged LAN and SAN market place instead of now watching Brocade and Cisco form the sidelines.

For now, congratulations to Mike Klayko and crew for demonstrating that they want to put up a fight and provide an alternative for their customers to Cisco and that they are serious about being a serious contender in the data infrastructure solution provider fight. For Cisco, looks like two of your competitors have now become one. Good luck and best wishes to both sides, Brocade and Cisco and I will be watching this battle from ring side as both parties line up and re-align their partner ecosystems.

Missing Dedupe Debate Detail!

Storage I/O trends

The de-dupe vendors like to debate details of their solutions, ranging from compression or de-dupe ratios, to hashing and caching algorithms, to processor vs. disk vs. memory, to in-band vs. out-of-band, pre or post processing among other items. At times the dedupe debates can get more lively than a political debate or even the legendary storage virtualization debates of yester year.

However one item that an IT professional recently mentioned that is not being addressed or talked about during the de-dupe debates is how IT customers will get around vendor lock-in. Never mind the usual lock-in debates of whose back-end storage or disk drives, whose server a de-dupe appliance software runs and so forth.

The real concern is how data in the future will be recoverable from a de-dupe solution similar to how data can be recovered from tape today. Granted this is an apple to oranges comparison at best. The only real similarity is that a backup or archive solution sends a data stream in a tar-ball or backup or archive save set or perhaps in a file format to the tape or de-dupe appliance. Then, the VTL or de-dupe appliance software puts the data into yet another format.

Granted not all tape media can be interchanged between different tape drives given format, generations and of course using the proper backup or archive application to un-pack the data for use. Probably a more applicable apple to oranges comparison would be how will IT personal get data back from a VTL (non de-duping) disk based storage system compared to getting data back from a VTL or de-dupe appliance.

Today and for the foreseeable future the answer is simple, if your pain point is severe and you need the benefits of de-dupe, then the de-dupe software and appliance is your point of vendor lock-in. If vendor lock-in is a main concern, take your time, do your homework and due diligence for solutions that reduce lock-in or at least give a reasonable strategy for data access in the future.

Welcome to the world of virtualized data and virtualized data protection. Here?s the golden rule for de-dupe and that is like virtualization, who ever controls the software and management meta data controls the vendor lock-in, good, bad or in-different, that?s the harsh reality.

For the record, I like de-dupe technology in general as part of an overall data footprint reduction strategy combined with archiving and real-time compression for on-line and off-line data. I see a very bright future for it moving forward. I also see many of the heavy thinking and heavy lifting issues to support large-scale deployments and processing getting addressed over time allowing de-dupe to move from mid markets to large-scale mainstream adoption.

Now, back to your regularly scheduled de-dupe debate drama!

Comfort Zones – Stating What Might Be Obvious to Some…

Storage I/O trends

Over the past couple of weeks I have talked with many IT professionals who work in IT data centers of varying size from different locations around the world. A couple of interesting patterns or trends if you prefer I have noticed are that while IT and storage professionals in general see disk based backup as the future and for some instances, a good tool today, there is still very much a comfort factor with magnetic tape.

The most cited reasons for continued use of tape being affordability, low power requirements, portability (assuming media is encrypted and secure) and familiar or comfort and confidence with the technology. A related trend or pattern is that while many IT professionals see the value and benefit of SSD including FLASH and RAM, there is also a concern or lack of confidence in the first so called enterprise class FLASH based SSD technology.

A related trend should hardly be a surprise in that enterprise customers I talk to who cling to tape as a data retention medium (even when using disk based backups) are also the most likely to have an early adopter aversion towards FLASH based enterprise storage. During discussions, what I also hear is that given time SSD including both RAM and enhanced or next generation FLASH will be adopted and deployed along magnetic hard disk drives (HDDs) and that HDDs will be used more in the future for backups and other data protection tasks.

Thus the consensus is that while HDDs have been declared dead by some with the arrival of FLASH and SSD, HDDs have joined the “Zombie” list of technologies declared dead, yet that continue to be produced and bought by customers. Other “Zombie” technologies include the IBM Mainframe, Fibre Channel, Magnetic Tapes, Copper based Ethernet and Printers among others. So with the magnetic HDD being over 50 years old, its safe to assume that magnetic HDD will be around for many more years, especially now that HDDs are on the “Zombie” technology list, a rather esteemed list I might add!

Ok, nuff said.
