This week, July 26-30, 2010, I am in Washington DC for the annual [2010 System Storage Technical University]. As with last year, we have joined forces with the System x team. Since we are in Washington DC this time, IBM added a "Federal Track" to focus on government challenges and solutions. So, basically, offering attendees the option to attend three conferences for one low price.
This conference was previously called the "Symposium", but IBM changed the name to "Technical University" to emphasize the technical nature of the conference. No marketing puffery like "Journey to the Private Cloud" here! Instead, this is bona fide technical training, qualifying attendees to count this towards their Continuing Professional Education (CPE).
(Note to my readers:The blogosphere is like a playground. In the center are four-year-olds throwing sand into each other's faces, while mature adults sit on benches watching the action, and only jumping in as needed. For example, fellow blogger Chuck Hollis (EMC) got sand in his face for promising to resign if EMC ever offered a tacky storage guarantee, and then [failed to follow through on his promise] when it happened.
Several of my readers asked me to respond to another EMC blogger's latest [fistful of sand].
A few months ago, fellow blogger Barry Burke (EMC) committed to [stick to facts] in posts on his Storage Anarchist blog. That didn't last long! BarryB apparently has fallen in line with EMC's over-promise-then-under-deliver approach. Unfortunately, I will be busy covering the conference and IBM's robust portfolio of offerings, so won't have time to address BarryB's stinking pile of rumor and hearsay until next week or later. I am sorry to disappoint.)
This conference is designed to help IT professionals make their business and IT infrastructure more dynamic and, in the process, help reduce costs, mitigate risks, and improve service. This technical conference event is geared to IT and Business Managers, Data Center Managers, Project Managers, System Programmers, Server and Storage Administrators, Database Administrators, Business Continuity and Capacity Planners, IBM Business Partners and other IT Professionals. This week will offer over 300 different sessions and hands-on labs, certification exams, and a Solutions Center.
For those who want a quick stroll through memory lane, here are my posts from past events:
- 2007 Storage Symposium: [Day 1,
- 2009 Storage Symposium: [
Day 2-Server Virtualization,
Day 3-Extraordinary Networks,
Day 5-Meet the Experts]

Continuing coverage of my week in Washington DC for the annual [2010 System Storage Technical University], I attended several XIV sessions throughout the week. There were many XIV sessions. I could not attend all of them. Jack Arnold, one of my colleagues at the IBM Tucson Executive Briefing Center, often presents XIV to clients and Business Partners. He covered all the basics of XIV architecture, configuration, and features like snapshots and migration. Carlos Lizarralde presented "Solving VMware Challenges with XIV". Ola Mayer presented "XIV Active Data Migration and Disaster Recovery".
Here is my quick recap of two in particular that I attended:
- XIV Client Success Stories - Randy Arseneau
Randy reported that IBM had its best quarter ever for the XIV, reflecting an unexpected surge shortly after my blog post debunking the DDF myth last April. He presented successful case studies of client deployments. Many followed a familiar pattern. First, the client would only purchase one or two XIV units. Second, the client would beat the crap out of them, putting all kinds of stress from different workloads. Third, the client would discover that the XIV is really as amazing as IBM and IBM Business Partners have told them. Finally, in the fourth phase, the client would deploy the XIV for mission-critical production applications.
- A large US bank holding company managed to get 5.3 GB/sec from a pair of XIV boxes for their analytics environment. They now have 14 XIV boxes deployed in mission-critical applications.
- A large equipment manufacturer compared the offerings among seven different storage vendors, and IBM XIV came out the winner. They now have 11 XIV boxes in production and another four boxes for development/test. They have moved their entire VMware infrastructure to IBM XIV, running over 12,000 guest instances.
- A financial services company bought their first XIV in early 2009 and now has 34 XIV units in production attached to a variety of Windows, Solaris, AIX, Linux servers and VMware hosts. Their entire Microsoft Exchange was moved from HP and EMC disk to IBM XIV, and experienced noticeable performance improvement.
- When a University health system replaced two competitive disk systems with XIV, their data center temperature dropped from 74 to 68 degrees Fahrenheit. In general, XIV systems are 20 to 30 percent more energy efficient per usable TB than traditional disk systems.
- A service provider that had used EMC disk systems for over 10 years evaluated the IBM XIV versus upgrading to EMC V-Max. The three year total cost of ownership (TCO) of EMC's V-Max was $7 Million US dollars higher, so EMC counter-proposed CLARiiON CX4 instead. But, in the end, IBM XIV proved to be the better fit, and now the customer is happy having made the switch.
- The manager of an information communications technology service provider was impressed that the XIV was up and running in just a couple of days. They now have over two dozen XIV systems.
- Another XIV client had lost all of their Computer Room Air Conditioning (CRAC) units for several hours. The data center heated up to 126 degrees Fahrenheit, but the customer did not lose any data on either of their two XIV boxes, which continued to run in these extreme conditions.
- Optimizing XIV Performance - Brian Cormody
This session was an update from the [one presented last year] by Izhar Sharon. Brian presented various best practices for optimizing the performance when using specific application workloads with IBM XIV disk systems.
- Oracle ASM: Many people allocate lots of small LUNs, because this made sense a long time ago when all you had was just a bunch of disks (JBOD). In fact, many of the practices that DBAs use to configure databases across disks become unnecessary with XIV. Wth XIV, you are better off allocating a few number of very large LUNs from the XIV. The best option was a 1-volume ASM pool with 8MB AU stripe. A single LUN can contain multiple Oracle databases. A single LUN can be used to store all of the logs.
- VMware: Over 70 percent of XIV customers use it with VMware. For VMFS, IBM recommends allocating a few number of large LUNs. You can specify the maximum of 2181 GB. Do not use VMware's internal LUN extension capability, as IBM XIV already has thin provisioning and works better to allow XIV to do this for you. XIV Snapshots provide crash-consistent copies without all the VMware overhead of VMware Snapshots.
- SAP: For planning purposes, the "SAPS" unit equates roughly to 0.4 IOPS for ERP OLTP workloads, and 0.6 IOPS for BW/BI OLAP workloads. In general, an XIV can deliver 25-30,000 IOPS at 10-15 msec response time, and 60,000 IOPS at 30 msec response time. With SAP, our clients have managed to get 60,000 IOPS at less than 15 msec.
- Microsoft Exchange: Even my friends in Redmond could not believe how awesome XIV was during ESRP testing. Five Exchange 2010 servers connected two a pair of XIV boxes using the new 2TB drawers managed 40,000 mailboxes at the high profile (0.15 IOPS per mailbox). Another client found four XIV boxes (720 drives) was able to handle 60,000 mailboxes (5GB max), which would have taken over 4000 drives if internal disk drives were used instead. Who said SANs are obsolete for MS Exchange?
- Asynchronous Replication: IBM now has an "Async Calculator" to model and help design an XIV async replication solution. In general, dark fiber works best, and MPLS clouds had the worst results. The latest 10.2.2 microcode for the IBM XIV can now handle 10 Mbps at less than 250 msec roundtrip. During the initial sync between locations, IBM recommends setting the "schedule=never" to consume as much bandwidth as possible. If you don't trust the bandwidth measurements your telco provider is reporting, consider testing the bandwidth yourself with [iPerf] open source tool.
Several members of the XIV team thanked me for my April 5th post [Double Drive Failure Debunked: XIV Two Years Later]. Since April 5th, IBM has sold more XIV units this quarter than any prior quarters. I am glad to have helped!

Monday morning of the [Oracle OpenWorld 2011] conference had Joe Tucci, CEO of EMC, present the keynote. Joe indicated that I.T. stands for "Industry in Transition". He had a chart that showed the history of IT, from the mainframe and mini-computer, to the PC and client/server era, and now to the Cloud era. He called these "waves of disruption". The catalysts for change are a "Budge Dilemma", "Information Deluge" and "Cyber Security". The keynote was very similar to what EMC presented at [VMworld] conference earlier this summer.
"We have failed our customers. Over the past 10 years, they spend 73% to maintain their existing systems, and only 27% for new."
--- Joe Tucci, EMC
While many people equate "EMC" and "Failure", I believe Joe was referring not just to his own company, but most of the other IT vendors as well. Analysts predict that from January 1, 2010 to December 31, 2019, the world of stored data will grow from 0.9 ZB to 35.2 ZB, which represents a 44x increase. During that same time, IT staff is only expected to grow 50 percent. A staggering 90 percent of this data will be unstructured (non-database) content. Meanwhile, the average company gets cyber-attacked 300 times per week.
The answer is Cloud Computing. A few years ago, EMC was trying to get people to go "private cloud" route instead of "public cloud", they now have a more realistic "hybrid cloud" approach similar to IBM. Of the clients that EMC works with, 35 percent are implementing some form of cloud, and another 30 percent are planning to. The tenents of Hybrid Cloud are "Efficiency", "Control" and "Choice" which equals "Agility".
Joe also mentioned that there is now a new "layering" for IT. Instead of storage, switches and servers, we have a cloud platform of shared resources, mobile devices like smartphones and tablets, and management.
Joe feels there is a massive opportunity where Cloud meets Big Data. A cute video showed a driver wearing a motorcycle helmet so you can't see his face get into an under-powered car with "VNXe" on the license plate. He punches in "Cloud and Big Data" into the GPS navigation system, and starts out on city streets. Then the car transforms to an under-utilized family sedan "VNX" on a highway in the middle of the desert, then transforms to an over-priced sports car labeled "VMAX" as it climbs into the mountains surrounded by fog. The video borrowed the "CARS" theme from the videos IBM developed for its 2008 launch of "Information Infrastructure" initiative.
EMC's Pat Gelsinger (CTO) and fellow blogger Chad Sakac did some demos of VMware vCenter. They called the VMware vSphere "the Datacenter-wide OS" indicating that EMC storage has 75 points of integration with their "partner" (VMware is majority-owned by EMC, so I am not sure if partner is the right term). If you don't count Itanium, SPARC, POWER and IBM Syste z architectures, VMware enjoys over 80 percent marketshare for server virtualization.
(Full disclosure: IBM is the leading reseller of VMware.)
Pat claims that 40 percent of Oracle Apps at EMC run VMware. For the longest time, Oracle refused support its apps on VMware, but they relaxed this restrictive policy back in 2009. Today, nearly 25 percent of Oracle Apps run virtualized. EMC claims that they can support 5 million VMs on a single VMAX, and can generate 1 million IOPS from a single VMware ESX host.
Chad did a demo of vFabric which allows a vCenter plug-in to kick up Database instances of OracleDB, MySQL, Hadoop, PostgreSQL, and GreenPlum (GreenPlum is EMC's version of open-source PostgreSQL).
Chad showed that VMware vMition could move workloads from servers without solid-state, to servers that are flash-enabled. Lightweight workloads can be moved from DAS-enabled servers to compute-enabled storage devices like their EMC Isilon. (EMC acquired Isilon to offer their me-too version of IBM's Scale-Out NAS [SONAS] product.) EMC announced their first "Solid-State on a PCIe card" from their Project Lightning initiative. These are 320 GB capacity, so they sounded like a me-too versino of IBM's [Fusion-io IOdrive] cards that IBM has had available for quite some time now.
Next, Pat and Chad talked about Big Data. The world is transforming from a manual scale-up model to an automated scale-out architecture. Moving from "islands" to "pools". They used a cute example of Car Insurance. Business Analytics were able to review a safe drivers record, including the driver's Facebook and Twitter activity, and give him a discount, and then review the bad driving habits of another driver, and raise the bad driver's rates.
EMC announced their "GreenPlum Analytics Platform" (GAP?). I often tell people that if you want to predict what EMC will announce next, just look at what IBM announced 18 months ago. This new platform sounds like their me-too version of IBM's [Smart Analytics System].
After EMC, Judith Sim from Oracle introduced the Ed Lee, the Mayor of San Francisco which was just named the "Greenest city in North America". He thanked the audience for contributing an estimated $100 million USD to his local economy. Also, he was happy that by eliminating paper-based handouts and conference materials, the audience saved 1,636 trees.
Mark Hurd, formerly CEO of HP, and now president of Oracle, gave some highlights of 2011, and what Oracle's strategy is going forward. He said that Oracle plans to provide complete stacks, complete choice, and have each component of the stack be best-of-breed. In 2011, Oracle introduced the new MySQL 5.5 database, Java 7 programming language, and the Solaris 11 operating system with ZFS file system. Oracle spent $4 Billion in R&D, and gained 20 percent growth in software licenses, which gave them 33 percent growth fiscally for 2011 year. Oracle acquired Larry Ellison's [Pillar Data] storage company. Oracle also launched a [Database Appliance].
Thomas Kurian, another Oracle executive, finished the keynote session. He started with yet another chart showing the historical transition from Mainframe to Tablet. He indicated that leading-edge OracleDB and their Fusion middleware combined with industry standard hardware provides 5-30x faster queries, 4-10x less disk space, and simplifies the data center footprint. Their Exadata provides what he likes to call "Hierarchical Storage Management" between DRAM, Flash Solid-State, and spinning disk.
(Note: I started my career at IBM in 1986 working on a product called DFHSM, the Data Facility Hierarchical Storage Manager! It is now a vibrant component of DFSMS, part of IBM's z/OS mainframe operating system.)
ps this new announcement is to address that deficiency.
Finally, Oracle announced their "Exadata Storage Expansion Rack". Many people realized that the Exadata was under-provisioned for storage, which explains why they have only sold a few thousand of them, so perha

I took over a hundred pictures at this event. Here are a few of my favorites from Monday and Tuesday.
- The IBM Booth #1111 Moscone South
I spent most of my time at the booth in the exhibition area. It was a huge booth, covering various software offerings in the front, and servers and storage systems in the back. Here I am next to the "IBM Watson" simulator, allowing people to play Jeopardy! game against Watson.
In the front was "EoS" which stands for "Exchanging Opinions for Solutions" -- an interactive screen developed by Somnio that allows people to enter questions and opinions and get crowd-sourced answers from people following the Twitter stream. The EoS was connected to the [IBM Mobile App] so people could follow the conversation.
- IBM Customer Appreciation Events
On Monday evening we had some customer appreciation events. First was for IBM customers of "JD Edwards", which runs on "IBM i" operating system on POWER servers. This was an elegant affair at the [Weinstein Gallery] surrounded by works of art by Pablo Picasso and Marc Chagall. One customer expressed concern that Oracle would functionally stabilize JD Edwards "World" software and force everyone to move over to "Enterprise One". I told him that I had seen the roadmap for "World" and there are three healthy releases planned for its future. He should have nothing to worry about. IBM and Oracle will work together to make sure our mutual customers get the solutions they need.
Later, we went to the "Infusion" bar for another "IBM appreciation" event with a live band. Here's a Polaroid photo taken of me in the crowd.
- Titan Gala Award Reception
On Tuesday night, Oracle gave out awards in 29 categories. IBM won three this year. I took a photo with the ladies from Beach Blanket Babylon, and a mermaid! Joining me to celebrate the awards were IBMers Carolann Kohler, Boyd Fenton, Sue Haad, and Susan Adomovich.
This is my first time attending Oracle OpenWorld, so naively I asked why there were only 29 categories and not an even 30. The IBMers joked that the 30th might as well have been "Best Server/Storage Platform for Integer Math" which Larry Ellison conceded that IBM's POWER 795 server wins over Oracle's new SPARC T4 Supercluster. As Larry said during his keynote "We still have some work to do to beat IBM!"
The event was held at the San Francisco City Hall, I got to walk on the red carpet, with lavish food and drink. I was even given a hand-rolled cigar! Thank you Oracle! We are proud to be your "Diamond Partner" helping our mutual customers get the most out of our solutions.
- The "Booth Babes" Controversy
At the EMC booth, these three lovely ladies, Jennifer, Tamara and Manuela, were just a few of the dozen so-called booth babes EMC hired from a local agency. Attendees with technical questions were directed to the EMC guys in the back of the booth, behind the wall.
IBM stopped using "booth babes" a long while ago. At IBM Booth #1111, we had a healthy balance of real men and women executives, technical experts, and support staff at the IBM booth.
Other IT vendors are starting to follow suit. Back in 2009, fellow blogger Stephen Foskett wrote
[(Don’t) Make Your Startup Look Stupid With Booth Babes And Chotchkies!], Denise Dubie, from NetworkWorld, discussed the debate in her post
[Booth babes don't wear glasses]. Wendy Shuchart weighs explains
[Why the VMworld 2011 booth babes are bad for IT]. Matt Simmons takes this a step further, suggesting an "Eliminate Booth Babes" campaign in his post
[Seriously, Stop with the Booth Babes].
A guy from EMC came over to our booth later to explain that EMC is at two other events this same week, and their technical staff is spread thin. EMC is a small company, and skilled technical people are in short supply. We get it. Not every IT vendor has an army of experts in every category like IBM.
I want to thank the IBM-Oracle Alliance team, especially Nancy Spurry and Carolann Kohler for having me involved in these events.

In keeping with the spirit to be a more kinder, gentler 2011, I decided last week to refrain from being the rain on someone else's parade that occurs immediately before, during or after a competitor's announcement or annual conference, and let EMC have their few moments in the spotlight last week. This of course allows me more time to learn about the announcements and reflect on marketplace reactions. Here's a quick look at the [EMC Press Release]:
- A new VNXe disk system
Of the 41 new storage technologies and products EMC announced last week, the VNXe is EMC's "me-too" product to compete against other low-end disk systems like the IBM System Storage DS3524 and N3000 series. It looks truly new, developed organically from the ground up, with a new architecture, new OS. It comes in either the 2U-high VNXe3100 or the 3U-high VNXe3300. These employ 3.5-inch SAS drives to provide Ethernet-based NFS, CIFS and iSCSI host attachment. The $10K USD price tag appears to be for the hardware only. As is typical for EMC, they charge software features in bundles or "suites", so the actual TCO will be much higher. I have not seen any announcements whether Dell plans to resell either the VNXe nor the VNX models, now that they have acquired Compellent.
- A new VNX disk system
Despite having a similar name as the VNXe, the VNX appears to be a re-hash of the Celerra/CLARiiON mess that EMC has been selling already, based on the old FLARE and DART operating systems of these older disk systems. This scales from 75 to 1000 SAS drives. While EMC calls the VNX "unified", it currently is only available in block-only and file-only models, with a future promise from EMC that they will offer a combined block-and-file version sometime in the future. EMC claims that the VNX will be faster than the predecessors, so hopefully that means EMC has joined the rest of the planet and will publish SPC-1 and SPC-2 benchmarks to back up that claim. They can compare against the SPC-1 benchmarks that our friends at NetApp ran against EMC CLARiiON.
- New software for the VMAX
A long time ago, EMC announced they would provide non-disruptive automated tiering. Their first delivery "FAST V1" handled entire LUNs at a time. EMC now has finally "FAST VP" which we expected was going to be called "FAST V2", which provides sub-LUN automated tiering between Solid-state and spinning disk drives.. Meanwhile, IBM has been delivering "Easy Tier" on the IBM System Storage DS8000 series, SAN Volume Controller, and Storwize V7000 disk systems.
- Data Domain Archiver
Competing against IBM, HP and Oracle in the tape arena, EMC's latest addition to the Data Domain family is designed for the long-term retention of backups? Archives of backups? Backups are short-lived, protecting against the unexpected loss from hardware failure or data corruption. Keeping backups as "archives" is generally a bad mistake, as it makes it hard to e-Discover the data you need when you need it, and may not have the appropriate hardware tor restore these old backups when you do find them.
I will have to dig deeper into all of these different technologies in separate posts in the future.
Am I dreaming? On his Storagezilla blog, fellow blogger Mark Twomey (EMC) brags about EMC's standard benchmark results, in his post titled [Love Life. Love CIFS.]. Here is my take:
- A Full 180 degree reversal
For the past several years, EMC bloggers have argued, both in comments on this blog, and on their own blogs, that standard benchmarks are useless and should not be used to influence purchase decisions. While we all agree that "your mileage may vary", I find standard benchmarks are useful as part of an overall approach in comparing and selecting which vendors to work with, and which architectures or solution approaches to adopt, and which products or services to deploy. I am glad to see that EMC has finally joined the rest of the planet on this. I find it funny this reversal sounds a lot like their reversal from "Tape is Dead" to "What? We never said tape was dead!"
- Impressive CIFS Results
The Standard Performance Evaluation Corporation (SPEC) has developed a series of NFS benchmarks, the latest, [SPECsfs2008] added support for CIFS. So, on the CIFS side, EMC's benchmarks compare favorably against previous CIFS tests from other vendors.
On the NFS side, however, EMC is still behind Avere, BlueArc, Exanet, and IBM/NetApp. For example, EMC's combination of Celerra gateways in front of V-Max disk systems resulted in 110,621 OPS with overall response time of 2.32 milliseconds. By comparison, the IBM N series N7900 (tested by NetApp under their own brand, FAS6080) was able to do 120,011 OPS with 1.95 msec response time.
Even though Sun invented the NFS protocol in the early 1980s, they take an EMC-like approach against standard benchmarks to measure it. Last year, fellow blogger Bryan Cantrill (Sun) gives his [Eulogy for a Benchmark]. I was going to make points about this, but fellow blogger Mike Eisler (NetApp) [already took care of it]. We can all learn from this. Companies that don't believe in standard benchmarks can either reverse course (as EMC has done), or continue their downhill decline until they are acquired by someone else.
(My condolences to those at Sun getting laid off. Those of you who hire on with IBM can get re-united with your former StorageTek buddies! Back then, StorageTek people left Sun in droves, knowing that Sun didn't understand the mainframe tape marketplace that StorageTek focused on. Likewise, many question how well Oracle will understand Sun's hardware business in servers and storage.)
- What's in a Protocol?
Both CIFS and NFS have been around for decades, and comparisons can sometimes sound like religious debates. Traditionally, CIFS was used to share files between Windows systems, and NFS for Linux and UNIX platforms. However, Windows can also handle NFS, while Linux and UNIX systems can use CIFS. If you are using a recent level of VMware, you can use either NFS or CIFS as an alternative to Fibre Channel SAN to store your external disk VMDK files.
- The Bigger Picture
There is a significant shift going on from traditional database repositories to unstructured file content. Today, as much as [80 percent of data is unstructured]. Shipments this year are expected to grow 60 percent for file-based storage, and only 15 percent for block-based storage. With the focus on private and public clouds, NAS solutions will be the battleground for 2010.
So, I am glad to see EMC starting to cite standard benchmarks. Hopefully, SPC-1 and SPC-2 benchmarks are forthcoming?

In his blog post, [The Lure of Kit-Cars], fellow blogger Chuck Hollis (EMC) uses an excellent analogy delineating the differences between kit-cars you build from parts, versus fully-integrated systems that you can drive off the car dealership showroom lot. The analogy holds relatively well, as IT departments can also build their infrastructure from parts, or you can get fully-integrated systems from a variety of vendors.
Is this what your data center looks like?
Certainly, this debate is not new. In my now infamous 2007 post [Supermarkets and Specialty Shops], I explained that there were clients that preferred to get their infrastructure from a single IT supermarket, like IBM or HP, while others were lured into thinking that buying separate parts from butchers, bakers and candlestick makers and other specialty shops was somehow a better idea.
Chuck correctly explains that in the early years of the automobile industry, before major car manufacturers had mass-production assembly lines, putting a car together from parts was the only way cars were made. Today, only the few most avid enthusiasts build cars this way. The majority get cars from a single seller and drive away. In my post [Resolving the Identity Crisis], I postulated that EMC appeared to be trying to shed itself of the "disk-only specialty shop" image and over to be more like IBM. Not quite a full IT Supermarket, but perhaps more like a [Trader Joe's] premium-priced retailer.
(If you find that EMC's focus on integrated systems appears to be a 180-degree about-face from their historical focus on selling individual best-of-breed products, see my previous discussion of Chuck's contradictions in my blog post: [Is Storage the Next Confusopoly].)
While companies like EMC might be making this transition, there is a lot of resistance and inertia from the customer marketplace. I agree with Chuck, companies should not be building kit-cars or IT infrastructures from parts, certainly not from parts sold from different vendors. In my post [Talking about Solutions not Products], I explained how difficult it was to change behavior. CIOs, IT directors and managers need to think differently about their infrastructure. Let's take a quick look at some choices:
Following Chuck's argument, it makes no sense to build a "kit-car" combining Oracle/Sun servers with EMC storage. Oracle would argue it makes more sense to run on integrated systems, business logic on their "Exalogic" system, and database processing on their "Exadata". Benchmark after benchmark, however, IBM is able to demonstrate that Oracle applications and databases run faster on IBM systems. Customers that want to run Oracle applications can run either on a full Oracle stack, or a full IBM stack, and both do better than a kit-car including EMC parts.
- Hewlett-Packard (HP)
HP has been working hard to keep up with IBM in this area. With their their partnership with Microsoft, and acquisitions of EDS, 3Com and 3PAR, they can certainly make a case for getting a full HP stack rather than a kit-car mixing HP servers with EMC disk storage. The problem is that HP is focused on a converged infrastructure for private cloud computing, but Microsoft is focused on Azure and public cloud computing. It will be interesting when these two big companies sort this out. Definitely watch this space.
If you squint your eyes and focus on the part of the world that only has x86 machines, then Dell can be seen as an IT supermarket. In my post about [Entry-Level iSCSI Offerings], I discuss how Dell's acquisition of EqualLogic was a signal that it was trying to get away from selling EMC specialty shop products, and building up its own set of offerings internally.
Cisco is new on the server scene, but has already made quite a splash. Here, I have to agree with Chuck's logic: the only time it makes sense to buy EMC disk storage at all is when it is part of an integrated "V-block". This is not really an IT supermarket situation, instead you park your car at the "Acadia Mini-Mall" and get what you need from Trader Joe's, Cisco UCS, and VMware stores.
But wait, if what you want is running VMware on Cisco servers, you might be better off with IBM System Storage N series or NetApp storage. In his blog post about [Enhanced Secure Multi-Tenancy], fellow Blogger Val Bercovici (NetApp) provides a convincing argument of why Cisco and VMware run better on an "N-block" rather than a "V-block". IBM N series provides A-SIS deduplication, and IBM Real-time Compression can provide additional capacity and performance improvements. That might be true, but whether you get your storage from EMC, NetApp or IBM, to me, you are still working with three different vendors in any case.
Of course, following Chuck's logic, it makes more sense for people with IBM servers, whether they be mainframes, POWER systems or x86 machines, to integrate these with IBM storage, IBM software and IBM services. IBM is the leading reseller of VMware, but also has a lot of business with Microsoft Hyper-V, Citrix Xen, Linux KVM, PowerVM, PR/SM and z/VM. While IBM has market leading servers, disk and tape systems, to compete for those RFP bids that just ask for one component or another, it prefers to sell fully-integrated systems, which IBM has been doing successfully since the 1950s.
Back in 2007, I mentioned how IBM's fully-integrated InfoSphere Balanced Warehouse [Trounced HP and Sun]. For business analytics, IBM offers the fully-integrated [IBM Smart Analytics Systems]. Today, IBM expanded its line of fully-integrated private cloud service delivery platforms with the announcement of the [IBM CloudBurst for on Power Systems], which does for POWER7 what the IBM CloudBurst for System x, Oracle Exalogic, or Acadia's V-block, do for x86.
IBM estimates that private clouds built on Power systems can be up to 70 percent less expensive than stand alone x86 servers.
Before he earned his PhD in Mechanical Engineering, my father was a car mechanic. I spent much of my teenage years covered in grease, helping my father assembling cars, lifting engines, and rebuilding carburetors. Certainly this was good father-son time, and I certainly did learn something in the process. Like the automobile industry, the IT industry has matured, and it makes no financial sense to build your own IT infrastructure from parts from different vendors.

This week, I am in beautiful Sao Paulo, Brazil, teaching Top Gun class to IBM Business Partners and sales reps. Traditionally, we have "Tape Thursday" where we focus on our tape systems, from tape drives, to physical and virtual tape libraries. IBM is the number #1 tape vendor, and has been for the past eight years.
(The alliteration doesn't translate well here in Brazil. The Portuguese word for tape is "fita", and Thursday here is "quinta-feira", but "fita-quinta-feira" just doesn't have the same ring to it.)
In the class, we discussed how to handle common misperceptions and myths about tape. Here are a few examples:
- Myth 1: Tape processing is manually intensive
In my July 2007 blog post [Times a Million], I coined the phrase "Laptop Mentality" to describe the problem most people have dealing with data center decisions. Many folks extend linearly their experiences using their PCs, workstations or laptops to apply to the data center, unable to comprehend large numbers or solutions that take advantage of the economies of scale.
For many, the only experience dealing with tape was manual. In the 1980s, we made "mix tapes" on little cassettes, and in the 1990s we recorded our favorite television shows on VHS tapes in the VCR. Today, we have playlists on flash or disk-based music players, and record TV shows on disk-based video recorders like Tivo. The conclusion is that tapes are manual, and disk are not.
Manual processing of tapes ended in 1987, with the introduction of a silo-like tape library from StorageTek. IBM quickly responded with its own IBM 3495 Tape Library Data Server in 1992. Today, clients have many tape automation choices, from the smallest IBM TS2900 Tape Autoloader that has one drive and nine cartridges, all the way to the largest IBM TS3500 multiple-library shuttle complex that can hold exabytes of data. These tape automation systems eliminate most of the manual handling of cartridges in day-to-day operations.
- Myth 2: Tape media is less reliable than disk media
For any storage media to be unreliable is to return the wrong information that is different than what was originally stored. There are only two ways for this to happen: if you write a "zero" but read back a "one", or write a "one" and read a "zero". This is called a bit error. Every storage media has a "bit error rate" that is the average likelihood for some large amount of data written.
According to the latest [LTO Bit Error rates, 2012 March], today's tape expects only 1 bit error per 10E17 bits written (about 100 Petabytes). This is 10 times more reliable than Enterprise SAS disk (1 bit per 10E16), and 100 times more reliable than Enterprise-class SATA disk (1 bit per 10E15).
Tape is the media used in "black boxes" for airplanes. When an airplane crashes, the black box is retrieved and used to investigate the causes of the crash. In 1986, the Space Shuttle Challenger exploded 73 seconds after take-off. The tapes in the black box sat on the ocean floor for six weeks before being recovered. Amazingly, IBM was able to successfully restore [90 percent of the block data, and 100 percent of voice data].
- Myth 3: Most tape restores fail
Why do people still believe that most tape restores fail? Curtis Preston, on his Backup Central blog, has a great post [Gartner Never Said 71 percent of Tape Restores Fail].
Analysts are quite upset when they are quoted out of context, but in this case, Gartner never said anything closely similar to this. Nor did the other analysts that Curtis investigated for similar claims. What Garnter did say was that disk provides an attractive alternative storage media for backup which can increase the performance of the recovery process.
Back in the 1990s, Savur Rao and I developed a patent to help backup DB2 for z/OS by using the FlashCopy feature of IBM's high-end disk system. The software method to coordinate the FlashCopy snapshots with the database application and maintain multiple versions was implemented in the DFSMShsm component of DFSMS. A few years later, this was part of a set of patents IBM cross-licensed to Microsoft for them to implement a similar software for Windows called Data Protection Manager (DPM). IBM has since introduced its own version for distributed systems called IBM Tivoli FlashCopy Manager that runs not just on Windows, but also AIX, Linux, HP-UX and Solaris operating systems.
Curtis suspects the "71 percent" citation may have been propogated by an ambitious product manager of Microsoft's Data Protection Manager, back in 2006, perhaps to help drive up business to their new disk-based backup product. Certainly, Microsoft was not the only vendor to disparage tape in this manner.
A few years ago, an [EMC failure brought down the State of Virginia] due to not just a component failure it its production disk system, but then made it worse by failing to recover from the disk-based remote mirror copy. Fortunately, the data was able to be restored from tape over the next four days. If you wonder why nobody at EMC says "Tape is Dead" anymore, perhaps it is because tape saved their butts that week.
(FTC Disclosure: I work for IBM and this post can be considered a paid, celebrity endorsement for all of the IBM tape and software products mentioned on this post. I own shares of stock in both IBM and Google, and use Google's Gmail for my personal email, as well as many other Google services. While IBM, Google and Microsoft can be considered competitors to each other in some areas, IBM has working relationships with both companies on various projects. References in this post to other companies like EMC are merely to provide illustrative examples only, based on publicly available information. IBM is part of the Linear Tape Open (LTO) consortium.)
Last year, Google lost the email data for half a million Gmail accounts due to a software error. Once again, tape came to the rescue, with [Google restoring lost Gmail data from tape backups].
- Myth 4: Vendors and Manufacturers are no longer investing in tape technology
IBM and others are still investing Research and Development (R&D) dollars to improve tape technology. What people don't realize is that much of the R&D spent on magnetic media can be applied across both disk and tape, such as IBM's development of the Giant Magnetoresistance read/write head, or [GMR] for short.
Most recently, IBM made another major advancement with tape with the introduction of the Linear Tape File Systems (LTFS). This allows greater portability to share data between users, and between companies, but treating tape cartridges much like USB memory sticks or pen drives. You can read more in my post [IBM and Fox win an Emmy for LTFS technology]!
Next month, IBM celebrates the 60th anniversary for tape. It is good to see that tape continues to be a vibrant part of the IT industry, and to IBM's storage business!

Continuing my post-week coverage of the [Data Center 2010 conference], Thursday morning had some interesting sessions for those that did not leave town last night.
- Interactive Session Results
In addition to the [Profile of Data Center 2010] that identifies the demographics of this year's registrants, the morning started with highlights of the interactive polls during the week.
- External or Heterogeneous Storage Virtualization
The analyst presented his views on the overall External/Heterogeneous Storage Virtualization marketplace. He started with the key selling points.
- Avoid vendor lock-in. Unlike the IBM SAN Volume Controller, many of the other storage virtualization products result in vendor lock-in.
- Leverage existing back-end capacity. Limited to what back-end storage devices are supported.
- Simplify and unify management of storage. Yes, mostly.
- Lower storage costs. Unlike the IBM SAN Volume Controller, many using other storage virtualization discover an increase in total storage costs.
- Migration tools. Yes, as advertised.
- Consolidation/Transition. Yes, over time.
- Better functionality. Potentially.
Shortly after several vendors started selling external/heterogeneous storage virtualization solutions, either as software or pre-installed appliances, major storage vendors that were caught with their pants down immediately started calling everything internally as also "storage virtualization" to buy some time and increase confusion.
While the analyst agreed that storage virtualization simplifies the view of storage from the host server side, it can complicate the management of storage on the storage end. This often comes up at the Tucson Briefing Center. I explain this as the difference between manual and automatic transmission cars. My father was a car mechanic, and since he is the sole driver and sole mechanic, he prefers manual transmission cars, easier to work on. However, rental car companies, such as Hertz or Avis, prefer automatic transmission cars. This might require more skills on behalf of their mechanics, but greatly simplifies the experience for those driving.
The analyst offered his views on specific use cases:
- Data Migration. The analyst feels that external virtualization serves as one of the best tools for data migration. But what about tech refresh of the storage virtualization devices themselves? Unlike IBM SAN Volume Controller, which allows non-disruptive upgrades of the nodes themselves, some of the other solutions might make such upgrades difficult.
- Consolidation/Transition. External virtualization can also be helpful, depending on how aggressive the schedule for consolidation/transition is performed.
- Improved Functionality/Usability. IBM SAN Volume Controller is a good example, an unexpected benefit. Features like thin provisioning, automated storage tiering, and so on, can be added to existing storage equipment.
The analyst mentioned that there were different types of solutions. The first category were those that support both internal storage and external storage virtualization, like the HDS USP-V or IBM Storwize V7000. He indicated that roughly 40 percent of HDS USP-V are licensed for virtualization. The second category were those that support external virtualization only, such as IBM SAN Volume Controller, HP Lefthand and SVSP, and so on. The third category were software-only Virtual Guest images that could provide storage virtualization capabilities.
The analyst mentioned EMC's failed product Invista, which sold less than 500 units over the past five years. The low penetration for external virtualization, estimated between 2-5 percent, could be explained from the bad taste that left in everyone considering their options. However, the analyst predicts that by 2015, external virtualization will reach double digit marketshare.
Having a feel for the demographics of the registrants, and specific interactive polling in each meeting, provides a great view on who is interested in what topic, and some insight into their fears and motivations.

Continuing my coverage of last week's Data Center Conference 2009, held Dec 1-4 in Las Vegas, I find some of the best sessions are those "user experiences" by the CIO or IT directors that successfully completed a project and showed the benefits and pitfalls. Matt Merchant, CTO of General Electric (GE), gave an awesome presentation on tapping Cloud Storage to reduce their backup and archive costs.
They were concerned over their lack of e-Discovery tools, the high fixed cost and large administrator personnel load of their Veritas NetBackup software environment, the possibility of corrupted tape media, new compliance and regulatory issues, and the risk of moving unencrypted cartridges to remote vaulting facilities like Iron Mountain. I found it interesting their backup/archive approach is that backups are re-classified as archive after they are 35 days old.
GE's Disk-to-Disk-to-Tape (D2D2T) approach was costing them 50 cents per GB/month. Changing to a D2D with remote replication addressed some of their concerns over tape, but was more costly at 79 centers per GB/month. Given that Backup and Archive represent 30 percent of their IT budget, the largest non-application expense, they reviewed their options:
- Continue with their Traditional BU/Archive approach
- Adopt Internal DAS using cheaper SATA disk drives
- Implement an Internal Cloud
- Use External Cloud services
General Electric had a long list of requirements:
- 99.99 percent Availability
- 99.999 percent Reliability and data integrity of the data
- Location independent access
- Meets HIPAA, SAS70, PCI compliance requirements
- Secure 3rd party access
- Eliminate GE operations management personnel
- Documented APIs
- Large file size uploads and resumable uploads (GE owns NBC Universal and some files are very large, movies can be 1.5 TB in size)
- Encryption at rest
- Multi-node capable, in other words, GE uploads it once and the Cloud Storage provider ensures that it is stored in two or more designated locations.
- Child-level billing/management. Here child relates to department, division or other sub-division for reporting and management purposes.
- Data integrity verification, such as with MD5 hash codes
GE evaluated Nirvanix, Amazon S3 and EMC and chose Nirvanix. They found Cloud storage worked best for backup, archive and large files, but was not a good fit for production/transactional data. However, they were not happy with proprietary APIs and vendor lock-in, so they wrote their own internal "Data Mover" called CloudStorage Manager that works with five different cloud storage providers through an abstraction layer. It is able to handle up to 8.8 GB per minute upload, has a policy engine that does encryption, compression and single-instance storage data deduplication at the file level. Some lessons learned include:
- Challenge the skeptics
- Run small pilot projects to get familiar with the technology and provider
- Socialize (have a beer or coffee with) your Security and Legal teams early and often
- Consider using multiple cloud providers
- Test many different scenarios
The end result? They now have Cloud-based backups and archive for their GE Corp, NBC Universal and GE Asset Management divisions running at only 32 cents per GB/month, representing a 40-60 percent savings over their previous methods. This includes backups of their external Web sites, archives of their digital and production assets, RMAN backups including development/staging databases. They plan to add out-of-region compliance archive in 2010. They also plan to monetize their intellectual property by offering "CloudStorage Manager" as a software offering for others.
