Continuing my coverage of the annual [2010 System Storage Technical University], I attended some sessions from the System x and Federal track side of this conference.
- Grid, SOA and Cloud Computing
Bill Bauman, IBM System x Field Technical Support Specialist and System x University celebrity, presented the differences between Grid, SOA and Cloud Computing. I thought this was an odd combination to compare and contrast, but his presentation was well attended.
- Grid - this is when two or more independently owned and managed computers are brought together to solve a problem. Some research facilities do this. IBM helped four hospitals connect their computers together into a grid to help analyze breast cancer. IBM also supports the [World Community Grid] which allows your personal computer to be connected to the grid and help process calculations.
- SOA - SOA, which stands for Service Oriented Architecture, is an approach to building business applications as a combination of loosely-coupled black-box components orchestrated to deliver a well-defined level of service by linking together business processes. I often explain SOA as the the business version of Web 2.0. You can download a free copy of the eBook "SOA for Dummies" at the [IBM Smart SOA] landing page.
- Cloud - A Cloud is a dynamic, scalable, expandable, and completely contractible architecture. It may consist of multiple, disparate, on-premise and off-premise hardware and virtualized platforms hosting legacy, fully installed, stateless, or virtualized instances of operating systems and application workloads.
Bill has his own blog, and has an interesting post [Cloud Computing, What it Is, and What it is Not] that appears to be the basis of this presentation.
- Chaos to Cloud
Tom Vezina, IBM Advanced Technical Sales Specialist, presented "Chaos to Cloud Computing". Survey results show that roughly 70 percent of cloud spend will be for private clouds, and 30 percent for public, hybrid or community clouds. Of the key motivations for public cloud, 77 percent or respondents cited reducing costs, 72 percent time to value, and 50 percent improving reliability.
Tom ran over 500 "server utilization" studies for x86 deployments during the past eight years. Of these, the worst was 0.52 percent CPU utilization, the best was 13.4 percent, and the average was 6.8 percent. When IBM mentions that 85 percent of server capacity is idle, it is mostly due to x86 servers. At this rate, it seems easy to put five to 20 guest images onto a machine. However, many companies encounter "VM stall" where they get stuck after only 25 percent of their operating system images virtualized.
He feels the problem is with the fact most Physical-to-Virtual (P2V) migrations are manual efforts. There are tools available like Novell [PlateSpin Recon] to help automate and reduce the total number of hours spent per migration.
- System x KVM Solutions
Boy, I walked into this one. Many of IBM's cloud offerings are based on the Linux hypervisor called Kernel-based Virtual Machine [a href="http://www.linux-kvm.org/page/Main_Page">KVM] instead of VMware or Microsoft Hyper-V. However, this session was about the "other KVM": keyboard video and mouse switches, which thankfully, IBM has renamed to Console Managers to avoid confusion. Presenters Ben Hilmus (IBM) and Steve Hahn (Avocent) presented IBM's line of Local Console Managers (LCM) and Global Console Managers (GCM) products.
LCM are the traditional KVM switches that people are familiar with. A single keyboard, video and mouse can select among hundreds of servers to perform maintenance or check on status. GCM adds KVM-over-IP capabilities, which means that now you can access selected systems over the Ethernet from a laptop or personal computer. Both LCM and GCM allow for two-level tiering, which means that you can have an LCM in each rack, and an LCM or GCM that points to each rack, greatly increasing the number of servers that can be managed from a single pane of glass.
Many severs have a "service processor" to manage the rest of the machine. IBM RSA II, HP iLO, and Dell DRAC4 are some examples. These allow you to turn on and off selected servers. IBM BladeCenter offers an Management Module that allows the chassis to be connected to a Console Manager and select a specific blade server inside. These can also be used with VMware viewer, Virtual Network Computing (VNC), or Remote Desktop Protocol (RDP).
IBM's offerings are unique it that you can have an optical CD/DVD drive or USB external storage attached at the LCM or GCM, and make it look like the storage is attached to the selected server. This can be used to install or upgrade software, transfer log files, and so on. Another great use, and apparently the motivation for having this session in the "Federal Track", is that the USB can be used to attach a reader for a smart card, known as a Common Access Card [CAC] used by various government agencies. This provides two-factor authentication [TFA]. For example, to log into the system, you enter your password (something you know) and swipe your employee badge smart card (something you have). The combination are validated at the selected server to provide access.
I find it amusing that server people limit themselves to server sessions, and storage people to storage sessions. Sometimes, you have to step "outside your comfort zone" and learn something new, something different. Open your eyes and look around a bit. You might just be surprised what you find.
(FTC note: I work for IBM. IBM considers Novell a strategic Linux partner. Novell did not provide me a copy of Platespin Recon, I have no experience using it, and I mention it only in context of the presentation made. IBM resells Avocent solutions, and we use LCM gear in the Tucson Executive Briefing Center.)

It seems everyone is talking about stacks, appliances and clouds.
On StorageBod, fellow blogger Martin Glassborow has a post titled [Pancakes!] He feels that everyone from Hitachi to Oracle is turning into the IT equivalent of the International House of Pancakes [IHOP] offering integrated stacks of software, servers and storage.
Cisco introduced its "Unified Computing System" about a year ago, [reinventing the datacenter with an all-Ethernet approach]. Cisco does not offer its own hypervisor software nor storage, so there are two choices. First, Cisco has entered a joint venture, called Acadia, with VMware and EMC, to form the Virtual Computing Environment (VCE) coalition. The resulting stack was named Vblock, which one blogger had hyphenated as Vb-lock to raise awareness to the proprietary vendor lock-in nature of this stack. Second, Cisco, VMware and NetApp had a similar set of [Barney press releases] to announce a viable storage alternative to those not married to EMC.
On StorageMojo, fellow blogger Robin Harris presents [A deep dive into Cisco’s UCS]. Here is an excerpt:
"Only when it makes sense. Oracle/Sun has the better argument: when you know exactly what you want from your database, we’ll sell you an integrated appliance that will do exactly that. And it’s fine if you roll your own.
But those are industry-wide issues. There are UCS/VCE specific issue as well:
- Cost. All the integration work among 3 different companies costs money. They aren’t replacing existing costs – they are adding costs. Without, in theory, charging more.
- Lock-in. UCS/Vblock is, effectively, a mainframe with a network backplane.
- Barriers to entry. Are there any? Cisco flagged hypervisor bypass and large memory support as unique value-add – and neither seems any more than a medium-term advantage.
- BOT? Build, Operate, Transfer. In theory Vblocks are easier and faster to install and manage. But customers are asking that Acadia BOT their new Vblocks. The customer benefit over current integrator practice? Lower BOT costs? Or?
- Price. The 3 most expensive IT vendors banding together?
- Longevity. Industry “partnerships” don’t have a good record of long-term success. Each of these companies has its own competitive stresses and financial imperatives, and while the stars may be aligned today, where will they be in 3 years? Unless Cisco is piloting an eventual takeover."
Similar questions and concerns were raised by others, including Greg Ferro's [Questions I Have About Cisco] and Gestalt IT's [One Year Later: Questioning Cisco UCS].
Fellow blogger Bob Sutor (IBM) has an excellent post titled
[Appliances and Linux
]. Here is an excerpt:
"In your kitchen you have special appliances that, presumably, do individual things well. Your refrigerator keeps things cold, your oven makes them hot, and your blender purees and liquifies them. There is room in a kitchen for each of these. They work individually but when you are making a meal they each have a role to play in creating the whole.
You could go out and buy the metal, glass, wires, electrical gadgets, and so on that you would need to make each appliance but it is is faster, cheaper, and undoubtably safer to buy them already manufactured. For each device you have a choice of providers and you can pay more for additional features and quality.
In the IT world it is far more common to buy the bits and pieces that make up a final solution. That is, you might separately order the hardware components, the operating system, and the applications, and then have someone put them all together for you. If you have an existing configuration you might add more blades or more storage devices.
You don’t have to do this, however, in every situation. Just from a hardware perspective, you can buy a ready-made machine just waiting for the on switch to be flicked and the software installed. Conversely, you might get a pre-made software image with operating system and applications in place, ready to be provisioned to your choice of hardware. We can get even fancier in that the software image might be deployable onto a virtual machine and so be a ready made solution runnable on a cloud.
Thus in the IT world we can talk about hardware-only appliances, software-only appliances (often called virtual software appliances), and complete hardware and software combinations. The last is most comparable to that refrigerator or oven in your kitchen."
If your company was a restaurant, how many employees would you have on hand to produce your own electricity from gas generators, pump your own water from a well, and assemble your own toasters and blenders from wires and motors? I think this is why companies are re-thinking the way they do their own IT.
Rather than business-as-usual, perhaps a mix of pre-configured appliances, consisting of software, server and storage stacked to meet a specific workload, connected to public cloud utility companies, might be the better approach. By 2013, some analysts feel that as many as 20 percent of companies might not even have a traditional IT datacenter anymore.
Fellow blogger David Salgado (Microsoft) rips into the IT industry for [marketing these "stacks" of components as "private clouds"]. Fellow blogger Mary-Jo Foley (Microsoft) asks ['Private cloud' = just another buzzword for on-premise datacenter?"] adds more attention to the confusion over the terms private and public cloud. Here's an excerpt that shows Microsoft's thinking in this area:
- "The private cloud:
- “By employing techniques like virtualization, automated management, and utility-billing models, IT managers can evolve the internal datacenter into a ‘private cloud’ that offers many of the performance, scalability, and cost-saving benefits associated with public clouds. Microsoft provides the foundation for private clouds with infrastructure solutions to match a range of customer sizes, needs and geographies.
- The public cloud:
- “Cloud computing is expanding the traditional web-hosting model to a point where enterprises are able to off-load commodity applications to third-party service providers (hosters) and, in the near future, the Microsoft Azure Services Platform. Using Microsoft infrastructure software and Web-based applications, the public cloud allows companies to move applications between private and public clouds.”
Finally, I saw this from fellow blogger, Barry Burke(EMC), aka the Storage Anarchist, titled [a walk through the clouds] which is really a two-part post.
The first part describes a possible future for EMC customers written by EMC employee David Meiri, envisioning a wonderful world with "No more Metas, Hypers, BIN Files...."
The vision is a pleasant one, and not far from reality. While EMC prefers to use the term "private cloud" to refer to both on-premises and off-premises-but-only-your-employees-can-VPN-to-it-and-your-IT-staff-still-manages-it flavors, the overall vision is available today from a variety of Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) providers.
A good analogy for "private cloud" might be a corporate "intranet" that is accessible only within the company's firewall. This allowed internal websites where information to be disseminated to employees could be posted, using standard HTML and standard web browsers that are already deployed on most PCs and workstations. Web pages running on an intranet can easily be moved to an external-facing website without too much rework or trouble.
The second part has Barry claiming that EMC has made progress towards a "Virtual Storage Server" that might be announced at next month's EMC World conference.
When people hear "Storage Virtualization" most immediately think of the two market leaders, IBM SAN Volume Controller and Hitachi Data Systems (HDS) Universal Storage Platform (USP) products. Those with a tape bent might throw in IBM's TS7000 virtual tape libraries or Oracle/Sun's Virtual Storage Manager (VSM). And those focused on software-only solutions might recall Symantec's Veritas Volume Manager (VxVM), DataCore's SANsymphony, or FalconStor's IPStor products.
But what about EMC's failed attempt at storage virtualization, the Invista? After five years of failing to deliver value, EMC has so far only publicised ONE customer reference account, and I estimate that perhaps only a few dozen actual customers are still running on this platform. Compare that to IBM selling tens of thousands of SAN Volume Controllers, and HDS selling thousands of their various USP-V and USP-VM products, and you quickly realize that EMC has a lot of catching up to do. EMC's first delivered Invista about 18 months after IBM SAN Volume Controller, similar to their introduction of Atmos being 18 months after our Scale-Out File Services (SoFS) and their latest CLARiiON-based V-Max coming out 18 months after IBM's XIV storage system.
So what will EMC's Invista follow-on "Virtual Storage Server" product look like? No idea. It might be another five years before you actually hear about a customer using it. But why wait for EMC to get their act together?
IBM offers solutions TODAY that can make life as easy as envisioned here. IBM offers integrated systems sold as ready-to-use appliances, customized "stacks" that can be built to handle particular workloads, residing on-premises or hosted at an IBM facility, and public cloud "as-a-service" offerings on the IBM Cloud.

They say "Great Minds think alike" and that imitation is "the sincerest form of flattery." Both of these quotes came to mind when I read fellow blogger Chuck Hollis' (EMC) excellent April 7th blog post [The 10 Big Ideas That Are Shaping IT Infrastructure Today]. Not surprisingly, some of his thoughts are similar to those I had presented two weeks ago in my March 22nd post [Cloud Computing for Accountants]. Here are two charts that caught my eye:
- Telephone Operators
On page 13 of my deck, I had an old black and white photo of telephone operators, as part of a section on the history of selecting "cloud" as the iconic graphic to represent all networks. Chuck has this same graphic on his chart titled "#1 The Industrialization of IT Infrastructure".
Looks like Chuck and I use the same "stock photo" search facility!
- Arms Dealers
On page 45 on my deck, I had a list of major "arms dealers" that deliver the hardware and software components needed to build Cloud Computing. Chuck has a similar chart, titled "#2 The Consolidation of the IT Industry", but with some interesting differences.
Let's look at some of the key differences:
- The left-to-right order is slightly different. I chose a 1-2-4-2-1 symmetrical pattern purely on aesthetic reasons. My presentation was to a bunch of accountants, and so I was trying not to make it sound like an "Infomercial" for IBM products and offerings. My sequence is roughly chronological, in that Oracle announced its intention to acquire Sun, then Cisco, VMware and EMC announced their VCE coalition, followed closely by Cisco, VMware and NetApp announcing they work together well also, followed by [HP extended alliance with Microsoft] on Jan 13, 2010. As the IT marketplace is maturing, more and more customers are looking for an IBM-like one-stop shopping experience, and certainly various "mini-mall" alliances have formed to try to compete in this space.
- I had HP and Microsoft in the same column, referring only to the above-mentioned January announcement. HP is all about private cloud hardware infrastructures, but Microsoft is all about "three screens and the public cloud", so not sure how well this alliance will work out from a Cloud Computing perspective. This was not to imply that the other stacks don't work well with Microsoft software. They all do. Perhaps to avoid that controversy, Chuck chose to highlight HP's acquisition of EDS services instead.
- I used the vendor logos in their actual colors. Notice that the colors black, blue and red occur most often. These happen to be the three most popular ballpoint pen ink colors found on the very same paper documents these computer companies are trying to eliminate. Paper-less office, anyone? Chuck chose instead to colorize each stack with his own color scheme. While blue for IBM and orange for Sun Microsystems make some sense, it is not clear if he chose green for Cisco/VMware/EMC for any particular reason. Perhaps he was trying to subtly imply that the VCE stack is more energy efficient? Or maybe the green refers to money to indicate that the VCE stack is the most expensive? Either way, I would pit IBM's server/storage/software stack up against anything of comparable price from these other stacks in any energy efficiency bake-off.
- What about the Cisco/VMware/NetApp combination? All three got together to assure customers this was a viable combination. IBM is the number one reseller of VMware, and VMware runs great with IBM's N series NAS storage, so I do not dispute Cisco's motivation here. It makes sense for Cisco to two-time EMC in this manner. Why should Cisco limit itself to a single storage supplier? Et tu VMware? Having VMware chose NetApp over its parent company EMC was a bit of a shock. No surprise that Chuck left NetApp out of his chart.
- No love for Dell? I give Dell credit for their work with Virtual Desktop Images (VDI), and for embracing Ubuntu Linux for their servers. Dell's acquisitions of EqualLogic iSCSI-based disk systems and Perot Systems for services are also worth noting. Dell used to resell some of EMC's gear, but perhaps that relationship continues to fade away, as I [predicted back in 2007]. Chuck's decision to leave Dell off his chart speaks volumes to where this relationship stands, and where it is going.
Perhaps we are all in just one big ["echo chamber"], as we are all coming up with similar observations, talking to similar customers, and reviewing similar market analyst reports. I am glad, at least this time, that Chuck and I for the most part agree where the marketplace is going. We live in interesting times!

The marketshare data for external disk systems has been released by IDC for 4Q09. Overall, the market dropped 0.7 percent, comparing 4Q09 versus 4Q08. While EMC was quick to remind everyone that they were able to [maintain their #1 position] in the storage subset of "external disk systems", with the same 23.7 percent marketshare they had back in 4Q08 and revenues that were essentially flat, the real story concerns the shifts in the marketplace for the other major players. IBM grew revenue 9 percent, putting it nearly 5 points of marketshare ahead of HP. HP revenues dropped 7 percent, moving it further behind. Not mentioned in the [IBM Press Release] were NetApp and Dell, neck and neck for fourth place, with NetApp gaining 16.8 percent in revenues, while Dell dropped 13.5 percent. Both NetApp and Dell now have about 8 percent marketshare each. These top five storage vendors represent nearly 70 percent of the marketshare.
Given that HP is IBM's number one competitor, not just in storage but all things IT, this was a major win. Bob Evans from InformationWeek interviews my fifth-line manager, IBM executive Rod Adkins [IBM Claims Hardware Supremacy] where he shares his views and opinions about HP, Oracle-Sun, Cisco and Dell.
I'll add my two cents on what's going on:
- Shift in Servers causes Shift in Storage
Hundreds of customers are moving away from HP and Sun over to IBM servers, and with it, are chosing IBM's storage offerings as well. IBM's rock-solid strategy (which I outlined in my post [Foundations and Flavorings]) has helped explain the different products and how they are positioned. HP's use of Itanium processors, and Sun's aging SPARC line, are both reasons enough to switch to IBM's lastest POWER7 processors, running AIX, IBM i (formerly i5/OS) and Linux operating systems.
- Thunder in the Clouds
Some analysts predict that by 2013, one out of five companies won't even have their own IT assets. IBM supports all flavors of private, public and hybrid cloud computing models. IBM has its own strong set of offerings, is also the number one reseller of VMware, and has cloud partnerships with both Google and Amazon. HP and Microsoft have recently formed an alliance, but they have different takes on cloud computing. HP wants to be the "infrastructure" company, but Microsoft wants to focus on its ["three screens and a public cloud"] strategy. Microsoft has decided not to make its Azure Cloud operating system available for private cloud deployments. By contrast, IBM can start you with a private cloud, then help you transition to a hybrid cloud, and finally to a public cloud.
In the latest eX5 announcement, IBM's x86-based servers can run 78 percent more virtual machines per VMware license dollar. This will give IBM an advantage as HP shifts from Itanium to an all x86-based server line.
- Network Attached Storage
There seems to be a shift away from FC and iSCSI towards NAS and FCoE storage networking protocols. This bodes bad for HP's acquisition of LeftHand, and Dell's acquisition of EqualLogic. IBM's SONAS for large deployments, and N series for smaller deployments, will compete nicely against HP's StorageWorks X9000 system.
- Storage on Paper no longer Eco-friendly
HP beats IBM when you include consumer products like printers, which some might consider "Storage on Paper". At IBM, we often joke that 96 percent of HP's profits come from over-priced ink cartridges. With the latest focus on the environment, people are printing less. I have been printing less myself, setting my default printer to generate a PDF file instead. There are several tools available for this, including [CutePDF] and [BullZip]. As IBM employees switch from Microsoft Office to IBM's [Lotus Symphony], it has built-in "export-to-PDF" capability as well. People are also going to their local OfficeMax or CartridgeWorld to get their cartridges refilled, rather than purchase new ones. That has to be hurting HP's bottom line.
- Don't Forget About Storage Management
The leading storage management suites today are IBM's Tivoli Storage Productivity Center and EMC's Control Center. HP's Storage Essentials doesn't quite beat either of these, and management software is growing in importance to more and more customers.

It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
- Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
- Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
- Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
- Simultaneous Background Tasks
The TSM server has many background administrative tasks:
- Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
- Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
- Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
- Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
- Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.

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?

From Timothy Morgan of [The Register
"With Cisco Systems, EMC, and VMware teaming up to sell integrated IT stacks, Oracle buying Sun Microsystems to create its own integrated stacks, and IBM having sold integrated legacy system stacks and rolling in profits from them for decades, it was only a matter of time before other big IT players paired off."
Once again we are reminded that IBM, as an IT "supermarket", is able to deliver integrated software/server/storage solutions, and our competitors are scrambling to form their own alliances to be "more like IBM." This week, IBM announced new ordering options for storage software with System x servers, including BladeCenter blade servers and IntelliStation workstations. Here's a quick recap:
- FastBack v6.1
IBM Tivoli Storage Manager FastBack v6.1 supports both Windows and Linux! FastBack is a data protection solution for ROBO (Remote Office, Branch Office) locations. It can protect Microsoft Exchange, Lotus Domino, DB2, Oracle applications. FastBack can provide full volume-level recovery, as well as individual file recovery, and in some cases Bare Machine Recovery. FastBack v6.1 can be run stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution.
- FlashCopy Manager v2.1
FlashCopy Manager uses point-in-time copy capabilities, such as SnapShot or FlashCopy, to protect application data using an application-aware approach for Microsoft Exchange, Microsoft SQL server, DB2, Oracle, and SAP. It can be used with IBM SAN Volume Controller (SVC), DS8000 series, DS5000 series, DS4000 series, DS3000 series, and XIV storage systems. When applicable, FlashCopy manager coordinates its work with Microsoft's Volume Shadow Copy Services (VSS) interface. FlashCopy Manager can provide data protection using just point-in-time disk-resident copies, or can be integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution to move backup images to external storage pools, such as low-cost, energy-efficient tape cartridges.
- General Parallel File System (GPFS) v3.3 Multiplatform
GPFS can support AIX, Linux, and Windows! Version 3.3 adds support for Windows 2008 Server on 64-bit chipset architectures from AMD and Intel. Now you can have a common GPFS cluster with AIX, Linux and Windows servers all sharing and accessing the same files. A GPFS cluster can have up to 256 file systems. Each of these file systems can be up to 1 billion files, up to 1PB of data, and can have up to 256 snapshots. GPFS can be used stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution with parallel backup streams.
For full details on these new ordering options, see the IBM [Press Release].

Wrapping up my coverage of the Data Center Conference 2009, the week ends with a celebration. This year we had six "Hospitality Suites" sponsored by various different vendors. Each suite has its own theme, decorations and entertainment. The first suite was VMware's "Cloud 9 Ultra Lounge" which offered blue cotton candy martinis. IBM is the leading reseller of VMware.
When the red martini liquid was poured on top of the blue cotton candy, the result was a nasty muddish brown grey color. The guy on the left chose to get the martini without the blue cotton candy. We joked that this is perhaps a good metaphor for cloud computing in general. It looks good on paper, until you actually put it all together and realize it does not look as blue and puffy as you were expecting. However, it tasted good!
||Next suite was sponsored by Cisco, one of IBM's storage networking partners. Cisco also decorated in blue, as the guy Jake in the middle demonstrates.|
Next suite was sponsored by Brocade, our supplier for IBM-branded networking gear. They went with a red-and-black color scheme. Sadly, many of my pictures inside involved straight jackets and unicycles, so not appropriate for this blog. However, it was easy to remember that they were talking about their "extraordinary networks". Makes you want to help out Brocade by contacting your nearest IBM storage sales rep and buy yourself a SAN768B or two.
Somewhere along the way, we picked up Hawaiian leis at the "Margaritaville" Hospitality Suite, compliments of sponsor APC by Schneider Electric. We had the best "Filet Mignon" appetizers at "Club Dedupe" by our competitor DataDomain, and some fun with my friends over at Computer Associates' "Top Gun" suite. Pictured at right are Paula Koziol with Christian Barrera from Argentina. A good time was had by all.

Continuing my coverage of the Data Center Conference 2009, held Dec 1-4 in Las Vegas, the title of this session refers to the mess of "management standards" for Cloud Computing.
The analyst quickly reviewed the concepts of IaaS (Amazon EC2, for example), PaaS (Microsoft Azure, for example), and SaaS (IBM LotusLive, for example). The problem is that each provider has developed their own set of APIs.
(One exception was [Eucalyptus], which adopts the Amazon EC2, S3 and EBS style of interfaces. Eucalyptus is an open-source infrastrcture that stands for "Elastic Utility Computing Architecture Linking Your Programs To Useful Systems". You can build your own private cloud using the new Cloud APIs included Ubuntu Linux 9.10 Karmic Koala termed Ubuntu Enterprise Cloud (UEC). See these instructions in InformationWeek article [Roll Your Own Ubuntu Private Cloud].)
The analyst went into specific Virtual Infrastructure (VI) and public cloud providers.
Private Clouds can be managed by VMware tools. For remote management of public IaaS clouds, there is [vCloud Express], and for SaaS, a new service called [VMware Go].
For private clouds based on Hyper-V, there is the [Dynamic Data Center toolkit]. For public PaaS cloud, Microsoft offers [Azure]. For remote management of SaaS, Microsoft offers [System Center Online Services].
Citrix is the Open Service Champion. For private clouds based on Xen Server, they have launched the [Xen Cloud Project] to help manage. For public clouds, they have [Citrix Cloud Center, C3], including an Amazon-based "Citrix C3 Labs" for developing and testing applications. For SaaS, they have [GoToMyPC and [GoToAssist].
Amazon offers a set of Cloud computing capabilities called Amazon Web Services [AWS]. For virtual private clouds, use the AWS Management Console. For IaaS (Amazon EC2), use [CloudWatch] which includes Elastic Load Balancing.
If you prefer a common management system independent of cloud provider, or perhaps across multiple cloud providers, you may want to consider one of the "Big 4" instead. These are the top four system management software vendors: IBM, HP, BMC Software, and Computer Associates (CA).
A survey of the audience found the number one challenge was "integration". How to integrate new cloud services into an existing traditional data center. Who will give you confidence to deliver not tools for remote management of external cloud services? Survey shows:
- 28 percent: VI Providers (VMware, Citrix, Microsoft)
- 19 percent: Big 4 System Management software vendors (IBM, HP, BMC, CA)
- 13 percent: Public cloud providers (Amazon, Google)
- 40 percent: Other/Don't Know
For internal private on-promise Clouds, the results were different:
- 40 percent: VI Providers (VMware, Citrix, Microsoft)
- 21 percent: Big 4 System Management software vendors (IBM, HP, BMC, CA)
- 13 percent: Emerging players (Eucalyptus)
- 26 percent: Other/Don't Know
Some final thoughts offered by the analyst. First, nearly a third of all IT vendors disappear after two years, and the cloud will probably have similar, if not worse, track record. Traditional server, storage and network administrators should not consider Cloud technologies as a death knell for in-house on-premises IT. Companies should probably explore a mix of private and public cloud options.
