A Rift At The High-End For Server Requirements?

Richard Fichera

We have been repeatedly reminded that the requirements of hyper-scale cloud properties are different from those of the mainstream enterprise, but I am now beginning to suspect that the top strata of the traditional enterprise may be leaning in the same direction. This suspicion has been triggered by the combination of a recent day in NY visiting I&O groups in a handful of very large companies and a number of unrelated client interactions.

The pattern that I see developing is one of “haves” versus “have nots” in terms of their ability to execute on their technology vision with internal resources. The “haves” are the traditional large sophisticated corporations, with a high concentration in financial services. They have sophisticated IT groups, are capable fo writing extremely complex systems management and operations software, and typically own and manage 10,000 servers or more. The have nots are the ones with more modest skills and abilities, who may own 1000s of servers, but tend to be less advanced than the core FSI companies in terms of their ability to integrate and optimize their infrastructure.

The divergence in requirements comes from what they expect and want from their primary system vendors. The have nots are companies who understand their limitations and are looking for help form their vendors in the form of converged infrastructures, new virtualization management tools, and deeper integration of management software to automate operational tasks, These are people who buy HP c-Class, Cisco UCS, for example, and then add vendor-supplied and ISV management and automation tools on top of them in an attempt to control complexity and costs. They are willing to accept deeper vendor lock-in in exchange for the benefits of the advanced capabilities.

Catching Up With SUSE -- The Attachmate Group Clarifies Branding And Role For SUSE

Richard Fichera

I recently had an opportunity to spend some time with SUSE management, including President and General Manager Nils Brauckmann, and came away with what I think is a reasonably clear picture of The Attachmate Group’s (TAG) intentions and of SUSE’s overall condition these days. Overall, impressions were positive, with some key takeaways:

  • TAG has clarified its intentions regarding SUSE. TAG has organized its computer holdings as four independent business units, Novell, NetIQ, Attachmate and SUSE, each one with its own independent sales, development, marketing, etc. resources. The advantages and disadvantages of this approach are pretty straightforward, with the lack of opportunity to share resources aiming the business units for R&D and marketing/sales being balanced off by crystal clear accountability and the attendant focus it brings. SUSE management agrees that it has undercommunicated in the past, and says that now that the corporate structure has been nailed down it will be very aggressive in communicating its new structure and goals.
  • SUSE’s market presence has shifted to a more balanced posture. Over the last several years SUSE has shifted to a somewhat less European-centric focus, with 50% of revenues coming from North America, less than 50% from EMEA, and claims to be the No. 1 Linux vendor in China, where it has expanded its development staffing. SUSE claims to have gained market share overall, laying claim to approximately 30% of WW Linux market share by revenue.
  • Focus on enterprise and cloud. Given its modest revenues of under $200 million, SUSE realizes that it cannot be all things to all people, and states that it will be focusing heavily on enterprise business servers and cloud technology, with less emphasis on desktops and projects that do not have strong financial returns, such as its investment in Mono, which it has partnered with Xamarin to continue development,.

Recent Benchmarks Reinforce Scalability Of x86 Servers

Richard Fichera

Over the past months server vendors have been announcing benchmark results for systems incorporating Intel’s high-end x86 CPU, the E7, with HP trumping all existing benchmarks with their recently announced numbers (although, as noted in x86 Servers Hit The High Notes, the results are clustered within a few percent each other). HP recently announced new performance numbers for their ProLiant DL980, their high-end 8-socket x86 server using the newest Intel E7 processors. With up to 10 cores, these new processors can bring up to 80 cores to bear on large problems such as database, ERP and other enterprise applications.

The performance results on the SAP SD 2-Tier benchmark, for example, at 25160 SD users, show a performance improvement of 35% over the previous high-water mark of 18635. The results seem to scale almost exactly with the product of core count x clock speed, indicating that both the system hardware and the supporting OS, in this case Windows Server 2008, are not at their scalability limits. This gives us confidence that subsequent spins of the CPU will in turn yield further performance increases before hitting system of OS limitations. Results from other benchmarks show similar patterns as well.

Key takeaways for I&O professionals include:

  • Expect to see at least 25% to 35% throughput improvements in many workloads with systems based on the latest the high-performance PCUs from Intel. In situations where data center space and cooling resources are constrained this can be a significant boost for a same-footprint upgrade of a high-end system.
  • For Unix to Linux migrations, target platform scalability continues become less of an issue.

HP And Oracle Customers React – Not Happy, But Coping

Richard Fichera

Since Oracle dropped their bombshell on HP and Itanium, I have fielded multiple emails and about a dozen inquiries from HP and Oracle customers wanting to discuss their options and plans. So far, there has been no general sense of panic, and the scenarios seem to be falling into several buckets:

  • The majority of Oracle DB/HP customers are not at the latest revision of Oracle, so they have a window within which to make any decisions, bounded on the high end by the time it will take them to make a required upgrade of their application plus DB stack past the current 11.2 supported Itanium release. For those customers still on Oracle release 9, this can be many years, while for those currently on 11.2, the next upgrade cycle will cause a dislocation. The most common application that has come up in inquiries is SAP, with Oracle’s own apps second.
  • Customers with other Oracle software, such as Hyperion, Peoplesoft, Oracle’s eBusiness Suite, etc., and other ISV software are often facing complicated constraints on their upgrades. In some cases decisions by the ISVs will drive the users toward upgrades they do not want to make. Several clients told me they will defer ISV upgrades to avoid being pushed into an unsupported version of the DB.

Intel Ups The Ante At The High End With New E7 CPUs

Richard Fichera

Bigger, Better, Faster Xeon CPUs

Intel today publicly announced its anticipated “Westmere EX” high end Westmere architecture server CPU as the E7, now part of a new family nomenclature encompassing entry (E3), midrange (E5), and high-end server CPUs (E7), and at first glance it certainly looks like it delivers on the promise of the Westmere architecture with enhancements that will appeal to buyers of high-end x86 systems.

The E7 in a nutshell:

  • 32 nm CPU with up to 10 cores, each with hyper threading, for up to 20 threads per socket.
  •  Intel claims that the system-level performance will be up to 40% higher than the prior generation 8-core Nehalem EX. Notice that the per-core performance improvement is modest (although Intel does offer a SKU with 8 cores and a slightly higher clock rate for those desiring ultimate performance per thread).
  • Improvements in security with Intel Advanced Encryption Standard New Instruction (AES-NI) and Intel Trusted Execution Technology (Intel TXT).
  • Major improvements in power management by incorporating the power management capabilities from the Xeon 5600 CPUs, which include more aggressive P states, improved idle power operation, and the ability to separately reduce individual core power setting depending on workload, although to what extent this is supported on systems that do not incorporate Intel’s Node Manager software is not clear.

Intel Discloses Details on “Poulson,” Next-Generation Itanium

Richard Fichera

This week at ISSCC, Intel made its first detailed public disclosures about its upcoming “Poulson” next-generation Itanium CPU. While not in any sense complete, the details they did disclose paint a picture of a competent product that will continue to keep the heat on in the high-end UNIX systems market. Highlights include:

  • Process — Poulson will be produced in a 32 nm process, skipping the intermediate 45 nm step that many observers expected to see as a step down from the current 65 nm Itanium process. This is a plus for Itanium consumers, since it allows for denser circuits and cheaper chips. With an industry record 3.1 billion transistors, Poulson needs all the help it can get keeping size and power down. The new process also promises major improvements in power efficiency.
  • Cores and cache — Poulson will have 8 cores and 54 MB of on-chip cache, a huge amount, even for a cache-sensitive architecture like Itanium. Poulson will have a 12-issue pipeline instead of the current 6-issue pipeline, promising to extract more performance from existing code without any recompilation.
  • Compatibility — Poulson is socket- and pin-compatible with the current Itanium 9300 CPU, which will mean that HP can move more quickly into production shipments when it's available.

Checking In On Linux – Latest Linux Releases Show Continued Progress

Richard Fichera

I’ve recently had the opportunity to talk with a small sample of SLES 11 and RH 6 Linux users, all developing their own applications. All were long-time Linux users, and two of them, one in travel services and one in financial services, had applications that can be described as both large and mission-critical.

The overall message is encouraging for Linux advocates, both the calm rational type as well as those who approach it with near-religious fervor. The latest releases from SUSE and Red Hat, both based on the 2.6.32 Linux kernel, show significant improvements in scalability and modest improvements in iso-configuration performance. One user reported that an application that previously had maxed out at 24 cores with SLES 10 was now nearing production certification with 48 cores under SLES 11. Performance scalability was reported as “not linear, but worth doing the upgrade.”

Overall memory scalability under Linux is still a question mark, since the widely available x86 platforms do not exceed 3 TB of memory, but initial reports from a user familiar with HP’s DL 980 verify that the new Linux Kernel can reliably manage at least 2TB of RAM under heavy load.

File system options continue to expand as well. The older Linux FS standard, ETX4, which can scale to “only” 16 TB, has been joined by additional options such as XFS (contributed by SGI), which has been implemented in several installations with file systems in excess of 100 TB, relieving a limitation that may have been more psychological than practical for most users.

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

Richard Fichera

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.

What Will Be The Fate Of SUSE Linux?

Richard Fichera

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.

Oracle Cancels OpenSolaris – What’s The Big Deal?

Richard Fichera

There has been turmoil and angst recently in the 0pen source community of late over Oracle’s decision to cancel OpenSolaris. Since this community can be expected to react violently anytime something is taken out of open source, the real question is whether this action has any impact on real-world IT and operations professionals. The short answer is no.

 Enterprise Solaris users, be they small, medium or large, are using it to run critical applications; and as far as we can tell, the uptake of OpenSolaris as opposed to Solaris supplied and sold by Sun was very low in commercial accounts, other than possibly a surge in test and dev environments. The decision to take Solaris into the open source arena was, in my opinion, fundamentally flawed, and Oracle’s subsequent decision to change this is eminently rational – Oracle’s customers almost certainly are not going to run their companies on an OS that is built and maintained by any open source community (even the vast majority of corporate Linux use is via a distribution supported by a major vendor and under a paid subscription model), and Oracle cannot continue to develop Solaris unless they have absolute control over it, just as is the case with every other enterprise OS. In the same vein, unless Oracle can also have an expectation of being compensated for their investments in future Solaris development, there is little motivation for them to continue to invest heavily in Solaris.
