Data Proteciton for Virtual Environments

Storage I/O trends

Server virtualization continues to be a popular industry focus, particularly to discuss IT data center power, cooling, floor space and environmental (PCFE) issues commonly called green computing along with supporting next generation virtualized data center environments. There are many challenges and options related to protecting data and applications in a virtual server environment.

Here’s a link to a new white paper by myself that looks at various issues, challenges and along with various approaches for enabling data protection for virtual environments. This in-depth report explains what your organization needs to know as it moves into a virtual realm. Topics include background and issues, glossary of common virtual terms, re-architecting data protection, technologies and techniques, virtual machine movement, industry trends and much more …

The report is called Data Protection Options for Virtualized Servers: Demystifying Virtual Server Data Protection, Have a look for yourself.

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!

Do Disk based VTLs draw less power than Tape?

The tape is dead debates rage on as they have for a decades which make for good press and discussion or debate during slow times, similar to coverage of what Britney Spears or Paris Hilton are or are not wearing.

In the on-going debates and Greenwashing of what technology or vendor is greener to prevent global warming, some recent tape is dead flare-ups have occurred including one hinting that tape libraries can draw more power than a disk based VTL with de-dupe are discussed over on Tony Pearson of IBM fame blog site as well as Beth Pariseau of TechTarget StorageSoup site.

I posted some comments on those sites along along with a link to a StorageIO Industry Trends and Perspective report titled “Energy Savings without Performance Compromise” as an example (look for an updated version of the comparison charts in the report in the not so distant future). The report looks at how different storage tiers including on-line disk, MAID, MAID 2.0 and tape libraries vary to address different PCFE (power, cooling, floor-space, environment) issues while supporting various service levels including performance, availability, capacity and energy use.

Additional related material can be found at www.storageio.com and www.greendatastorage.com including the Industry Trends and Perspective Report Business “Benefits of Data Footprint Reduction in general covering archiving, compression (on-line and off-line) along with de-duplication

SNW Spring 2008

The Spring 2008 edition of SNW was this past week in Orlando FL and I spent a couple of days there for some briefings as well as give a presentation.

From an attendance standpoint, certainly it did not feel or look like one of the largest SNW events that I have been to over that past several years and yes there were in fact some real IT personal there, however nothing like on the scale of what you would see at a Storage Decisions, VMworld or any of the other customer/IT personal focused show.

However keeping in mind that SNW is first a vendor and SNIA event that just happens to have some IT customers attending. This edition of SNW seemed more sparse given the size of the venue and how spread out things were along with the high degree of over-subscription or number of concurrent sessions (which had from 7 to up to 8 sessions at the same time) that are trying to be squeezed into a small timeframe with a relatively small audience compared to other events.

For me it was time well spent with the great meetings and ad-hoc discussions that I had in the short period while in Orlando even with the decline in attendance compared to past years. There is a shift going on and there are certainly many other large events to compete with SNW for attendees and participants many of which particularly for IT customers seem to be growing in popularity.

IMHO its time for the SNW show organizers to take a good look at the model of SNW Europe for some ideas on how to tweak and tune the US-based event especially if they want to continue to do a twice a year event.

Here’s a link to download a copy of my presentation Beyond Green-wash: Power, Cooling, Floor-space, Environmental (PCFE) and green Issues, Trends and Solutions from SNW.

On the StorageIO website you can find links to industry Trends and Perspective white papers as well as other content addressing PCFE and green related issues including MAID, Intelligent Power Management and MAID 2.0, SSD, Virtualization and Data Footprint Reduction among others.

Drop me a note or comment about what you are encountering or your thoughts or any interesting findings about IT data center PCFE and green issues and check out storageioblog.com if you have not recently done so.

Wide World of Archiving – Life Beyond Compliance

Earlier this week I did a keynote talk at a TechTarget event in the New York city area titled the “Wide World of Archiving – Life Beyond Compliance” with the basic theme that archiving and data preservation for future or possible future use is not unique or exclusive to SARBOX, HIPPA, CFR, PCI, OHSAS, ISO or other members of the common alphabet soup of governmental or industry regulatory compliance needs.

The basic theme is that archiving can be used to discuss many IT and business pain points and issues from preserving project oriented or seasonal data to off-loading un-used or seldom used data to free up resources to meet power, cooling, floor space and environmental (PCFE) issues
“aka Green”
along with boosting performance for on-line access as well as backup, BC and DR.

The challenge however is that archiving while a powerful technique, is also complex in that it requires hardware and mediums to park your data onto, software to find and then execute policies defined by someone to move data to the archive medium and if applicable, delete or cleanup data that has been moved all of which has cost and application specific issues. Then the human side which is more involved than simply throwing head count at the tasks and avoiding the mistakes of the Mythical Man Month.

The human side of archiving is the glue to make it work in that similar to cleaning out your garage, attic, basement or store-room, you can have someone come and do the real work, however do they have the insight to know what to keep and what to discard? Sure that’s an overly simple example, and there are plenty of search and discovery software management tool vendors who will be more than happy to show you a demo of their wares that will discovery and classify and categorize and index what data you have as well as interface with policy managers, data movers and archiving devices.

However who is going to tell the management tools what policies are applicable and the different variances for your different business segments or activities? Consequently the key to making archiving work particularly on a broader basis is to get internal personal familiar with your business, IT personal, as well as external subject matter experts involved all of which leads to a challenge and dilemma of is it cheaper to just buy more energy-efficient, space-saving storage than to pay the fees to find, manage, move and archive data. Talking with one of the attendees who brought up some good points that this all makes sense however there is a scaling challenge and when dealing with 100’s of TBytes or PBytes, the complexity increases.

This is where the notion of scaling with stability comes into play in that many solutions exist to address different functionality for example archiving, de-duping, compression, server or storage virtualization, thin-provisioning among many others however how do they scale with stability. That is, how stable or reliable do the solutions remain when scaling from 10s to 100’s to 10,000’s or even 100,000’s users, email boxes, sessions, streams or from 10’s of TBytes to 10’s of PBytes? How does the performance hold up, how does the availability hold up, how does the management and on-going care and feeding change for the better or worse? Concerns around scaling is a common issue I hear from IT organizations pertaining to both hardware and software tools in that what works great during a WebEx demo or PowerPoint or pdf slide show may be different from real-world performance, management, reliability and complexity concerns. After all, have you ever seen a WebEx or live office or PowerPoint or PDF slide deck showing a hardware or software based solution that could not scale or provide transparent interoperability? That would be akin to finding a used car sales rep who gives you a tour of how a car was refurbished inside and out after it was declared totaled by the previous owners insurance company after the last great flood or hurricane.

Getting back to archiving, and not trying to conquer all of your data at one time, take a divide and conquer approach, go for some low hanging fruit where your chances of success go up that you can then build some momentum and perhaps a business case to do a larger project. Also, one solution particularly one archiving software solution may not be applicable to all of your needs in that you may need a tool specialized for email, one for databases and another general purpose tool. Likewise you may need to engage different subject matter experts to help you with policy definition and establishing rules to meet different requirements which is where business partners can come into play with either their in-house staff, partners, or associates that they work with for different issues and needs.

Look beyond the hardware and software, look at the people or human and knowledge side of archiving as well as look beyond archiving for compliance as there is a much bigger wide world of archiving and opportunity. If you remember the ABC sports TV show “Wide World of Sports” you may recall Jim McCay saying “Spanning the globe to bring you the constant variety of sports… the thrill of victory… and the agony of defeat… the human drama of athletic competition… This is “ABC’s Wide World of Sports!”.

From an archiving perspective, keep this in mind in that there is a wide world of opportunities for archiving, the thrill of victory are the benefits, the agony of defeat are the miss-steps, lack of scaling, out of control costs or complexity, the human drama is how to make or break a solution, this is the “Wide World of Archiving”…

Rest assured, some form of archiving structured database, semi-structured email with attachments and un-structured word, PowerPoint, PDF, MP3 and other data is in your future, it’s a matter of when. Archiving is just one of many tools available for effectively managing your data and addressing data footprint sprawl particular for data that you can not simply delete and ignore, if you need it to go forward, you need to keep it. Or, as a friend of mine says You can’t go forward unless you can go back. Likewise, you can’t manage what you don’t know about; you can’t move and delete what you can’t manage.

Look for solution providers who are not looking to simply get you to buy the latest and greatest archiving storage device, or, the slickest archiving management tool with a Uhi Gui that rivals those on an Wii or Xbox, or, that is looking to simply run up billable hours. That’s a balancing act requires investing time with different business solution providers to see where their core business is, how they can scale, where and how they make their money to help you decide where and how they are fit as opposed to simply adding complexity to your environment and existing issues.
