ScaleMP – Interesting Twist On Systems Scalability And Virtualization

I just spent some time talking to ScaleMP, an interesting niche player that provides a server virtualization solution. What is interesting about ScaleMP is that rather than splitting a single physical server into multiple VMs, they are the only successful offering (to the best of my knowledge) that allows I&O groups to scale up a collection of smaller servers to work as a larger SMP.

Others have tried and failed to deliver this kind of solution, but ScaleMP seems to have actually succeeded, with a claimed 200 customers and expectations of somewhere between 250 and 300 next year.

Their vSMP product comes in two flavors, one that allows a cluster of machines to look like a single system for purposes of management and maintenance while still running as independent cluster nodes, and one that glues the member systems together to appear as a single monolithic SMP.

Does it work? I haven’t been able to verify their claims with actual customers, but they have been selling for about five years, claim over 200 accounts, with a couple of dozen publicly referenced. All in all, probably too elaborate a front to maintain if there was really nothing there. The background of the principals and the technical details they were willing to share convinced me that they have a deep understanding of the low-level memory management, prefectching, and caching that would be needed to make a collection of systems function effectively as a single system image. Their smaller scale benchmarks displayed good scalability in the range of 4 – 8 systems, well short of their theoretical limits.

My quick take is that the software works, and bears investigation if you have an application that:

  1. Either is certified to run with ScaleMP (not many), or one where that you control the code.
  2. You understand the memory reference patterns of the application, and

Oracle Rolls Out Private Cloud Architecture And World-Record Transaction Performance

On Dec. 2, Oracle announced the next move in its program to integrate its hardware and software assets, with the introduction of Oracle Private Cloud Architecture, an integrated infrastructure stack with Infiniband and/or 10G Ethernet fabric, integrated virtualization, management and servers along with software content, both Oracle’s and customer-supplied. Oracle has rolled out the architecture as a general platform for a variety of cloud environments, along with three specific implementations, Exadata, Exalogic and the new Sunrise Supercluster, as proof points for the architecture.

Exadata has been dealt with extensively in other venues, both inside Forrester and externally, and appears to deliver the goods for I&O groups who require efficient consolidation and maximum performance from an Oracle database environment.

Exalogic is a middleware-targeted companion to the Exadata hardware architecture (or another instantiation of Oracle’s private cloud architecture, depending on how you look at it), presenting an integrated infrastructure stack ready to run either Oracle or third-party apps, although Oracle is positioning it as a Java middleware platform. It consists of the following major components integrated into a single rack:

  1. Oracle x86 or T3-based servers and storage.
  2. Oracle Quad-rate Infiniband switches and the Oracle Solaris gateway, which makes the Infiniband network look like an extension of the enterprise 10G Ethernet environment.
  3. Oracle Linux or Solaris.
  4. Oracle Enterprise Manager Ops Center for management.

Open Data Center Alliance – Lap Dog Or Watch Dog?

In October, with great fanfare, the Open Data Center Alliance unfurled its banners. The ODCA is a consortium of approximately 50 large IT consumers, including large manufacturing, hosting and telecomm providers, with the avowed intent of developing standards for interoperable cloud computing. In addition to the roster of users, the announcement highlighted Intel with an ambiguous role as a technology advisor to the group. The ODCA believes that it will achieve some weight in the industry due to its estimated $50 billion per year of cumulative IT purchasing power, and the trade press was full of praises for influential users driving technology as opposed to allowing rapacious vendors such as HP and IBM to drive users down proprietary paths that lead to vendor lock-in.

Now that we’ve had a month or more to allow the purple prose to settle a bit, let’s look at the underlying claims, potential impact of the ODCA and the shifting roles of vendors and consumers of technology. And let’s not forget about the role of Intel.

First, let me state unambiguously that one of the core intentions of the ODCA, the desire to develop common use case models that will in turn drive vendors to develop products that comply with the models based on the economic clout of the ODCA members (and hopefully there will be a correlation between ODCA member requirements and those of a wider set of consumers), is a good idea. Vendors spend a lot of time talking to users and trying to understand their requirements, and having the ODCA as a proxy for the requirements of a lot of very influential customers will be a benefit to all concerned.

What Will Be The Fate Of SUSE Linux?

As an immediate reaction to the recent announcement of Attachmate’s intention to acquire Novell, covered in depth by my colleagues and synthesized by Chris Voce in his recent blog post, I have received a string of inquiries about the probable fate of SUSE LINUX. Should we continue to invest? Will Attachmate kill it? Will it be sold?

Reduced to its essentials the answer is that we cannot predict the eventual ownership of SUSE Linux, but it is almost certain to remain a viable and widely available Linux distribution. SUSE is one of the crown jewels of Novell’s portfolio, with steady growth, gaining market share, generating increasing revenues, and from the outside at least, a profitable business.

Attachmate has two choices with SUSE – retain it as a profitable growth engine and attachment point for other Attachmate software and services, or package it up for sale. In either case they have to continue to invest in the product and its marketing. If Attachmate chooses to keep it, SUSE Linux will behave as it did with Novell. If they sell it, its acquirer will be foolish to do anything else. Speculation about potential acquirers has included HP, IBM, Cisco and Oracle, all of whom could make use of a Linux distribution as an internal product component in addition to the software and service revenues it could engender. But aside from an internal platform, for SUSE to have value as an industry alternative to Red Hat, it would have to remain vendor agnostic and widely available.

With the inescapable caveat that this is a developing situation, my current take on SUSE Linux is that there is no reason to back away from it or to fear that it will disappear into the maw of some giant IT company.

SUSE users, please weigh in.

Checking In With Cisco UCS – Continued Momentum, Decoupled From Corporate Malaise

I met recently with Cisco’s UCS group in San Jose to get a quick update on sales and maybe some hints about future development. The overall picture is one of rapid growth decoupled from whatever pressures Cisco management has cautioned about in other areas of the business.

Overall, according to recent disclosure by Cisco CEO John Chambers, Cisco’s UCS revenue is growing at a 550% Y/Y growth rate, with the most recent quarterly revenues indicating a $500M run rate (we make that out as about $125M quarterly revenue). This figure does not seem to include the over 4,000 blades used by Cisco IT, nor does it include units being consumed internally by Cisco and subsequently shipped to customers as part of appliances or other Cisco products. Also of note is the fact that it is fiscal Q1 for Cisco, traditionally its weakest quarter, although with an annual growth rate in excess of 500% we would expect that UCS sequential quarters will be marching to a totally different drummer than the overall company numbers.

Oracle Releases Solaris 11 — Game Changer Or Place Keeper?

Oracle recently announced the availability of Solaris 11 Express, the first iteration of its Solaris 11 product cycle. The feature set of this release is along the lines promised by Oracle at their August analyst event this year, including:

  • Scalability enhancements to set it up for future systems with higher core counts and requirements to schedule large numbers of threads.
  • Improvements to zFS, Oracle’s highly scalable file system.
  • Reduction of boot times to the range of 10 seconds — a truly impressive accomplishment.
  • Optimizations to support Oracle Exadata and Exalogic integrated solutions. While some of these changes may be very specific to Oracle’s stack, most of them are almost certain to improve any application that requires some combination of high thread counts, large memory and low-latency communications with either 10G Ethernet or Infiniband.
  • Improvements in availability due to reductions on the number of reboot scenarios, improvements in patching and improved error recovery. This is hard to measure, but Oracle claims they are close to an OS which does not need to come down for normal maintenance, a goal of all of the major UNIX vendors and long a signature of mainframe environments.

Lies, Damned Lies, And Statistics . . . And Benchmarks

I have been working on a research document, to be published this quarter, on the impact of 8-socket x86 servers based on Intel’s new Xeon 7500 CPU. In a nutshell, these systems have the performance of the best-of-breed RISC/UNIX systems of three years ago, at a substantially better price, and their overall performance improvement trajectory has been steeper than competing technologies for the past decade.

This is probably not shocking news and is not the subject of this current post, although I would encourage you to read it when it is finally published. During the course of researching this document I spent time trying to prove or disprove my thesis that x86 system performance solidly overlapped that of RISC/UNIX with available benchmark results. The process highlighted for me the limitations of using standardized benchmarks for performance comparisons. There are now so many benchmarks available that system vendors are only performing each benchmark on selected subsets of their product lines, if at all. Additionally, most benchmarks suffer from several common flaws:

  • They are results from high-end configurations, in many cases far beyond the norm for any normal use cases, but results cannot be interpolated to smaller, more realistic configurations.
  • They are often the result of teams of very smart experts tuning the system configurations, application and system software parameters for optimal results. For a large benchmark such as SAP or TPC, it is probably reasonable to assume that there are over 1,000 variables involved in the tuning effort. This makes the results very much like EPA mileage figures — the consumer is guaranteed not to exceed these numbers.

Fujitsu – Ready To Play In North America?

Fujitsu? Who? I recently attended Fujitsu’s global analyst conference in Boston, which gave me an opportunity to check in with the best kept secret in the North American market. Even Fujitsu execs admit that many people in this largest of IT markets think that Fujitsu has something to do with film, and few of us have ever seen a Fujitsu system installed in the US unless it was a POS system.

So what is the management of this global $50 Billion information and communications technology company, with a competitive portfolio of client, server and storage products and a global service and integration capability, going to do about its lack of presence in the world’s largest IT market? In a word, invest. Fujitsu’s management, judging from their history and what they have disclosed of their plans, intends to invest in the US over the next three to four years to consolidate their estimated $3 Billion in N. American business into a more manageable (simpler) set of operating companies, and to double down on hiring and selling into the N. American market. The fact that they have given themselves multiple years to do so is very indicative of what I have always thought of as Fujitsu’s greatest strength and one of their major weaknesses – they operate on Japanese time, so to speak. For an American company to undertake to build a presence over multiple years with seeming disregard for quarterly earnings would be almost unheard of, so Fujitsu’s management gets major kudos for that. On the other hand, years of observing them from a distance also leads me to believe that their approach to solving problems inherently lacks the sense of urgency of some of their competitors.

Walking The Walk – Mobile Devices And The Infrastructure & Operations Group

Recently I’ve been living a double life. By day a mild-mannered functionary for Forrester Research, helping I&O professionals cope with the hurly-burly of our rapid-paced world. By night I have been equipping myself with an iPhone, iPad and trying out any other mobile devices I can get my hands on, including Dell Stream, Android phones, and the incredibly appealing new Apple Macbook Air. While my colleague Ted Schadler has been writing on these devices from a more strategic perspective, I wanted to see what the daily experience felt like and simultaneously get a perspective from our I&O customers about their experiences.

So, the first question, is the mobile phenomenon real? The answer is absolutely yes. While the rise of mobile devices is a staple of every vendor’s strategic pitch, it also seems to be a real trend. In conversations with I&O groups, I have been polling them on mobile devices in their company, and the feedback has been largely the same – employees are buying their own consumer devices and using them for work, forcing I&O, security and email/collaboration application owners, often well outside of plan, to support them. Why can’t IT groups “just say no”? The answer is that IT in rational companies is fundamentally in the fundamental business of enabling business, and the value and productivity unlocked by these devices is too much to pass up.

IBM Acquires BNT – Nuclear War In The Converged Infrastructure World?

There has been a lot of press about IBM’s acquisition of BNT (Blade Network Technologies) focusing on the economics and market share of BNT as a competitor to Cisco and HP’s ProCurve/3Com franchise. But at its heart the acquisition is more about defending and expanding a position in the emerging converged server, networking, and storage infrastructure segment than it is about raw switch port market share. It is also a powerful vindication of the proposition that infrastructure convergence is driving major realignment in the vendor industry.

Starting with HP’s success with its c-Class blade servers and Virtual Connect technology, and escalating with Cisco’s entrance into the server market, IBM continued its investment in its Virtual Fabric and Open Fabric Manager technology, heavily leveraging BNT’s switch platforms. At some point it became clear that BNT was a critical element of IBM’s convergence strategy, with IBM’s plans now heavily dependent on a vendor with whom they had an excellent, but non-exclusive relationship, and one whose acquisition by another player could severely compromise their product plans. Hence the acquisition. Now that it owns BNT, IBM can capitalize on its excellent edge network technology for further development of its converged infrastructure strategy without hesitation about further leveraging BNT’s technology.
