Earlier this week at its Discover customer event, HP announced a significant set of improvements to its already successful c-Class BladeSystem product line, which, despite continuing competitive pressure from IBM and the entry of Cisco into the market three years ago, still commands approximately 50% of the blade market. The significant components of this announcement fall into four major functional buckets – improved hardware, simplified and expanded storage features, new interconnects and I/O options, and serviceability enhancements. Among the highlights are:
Direct connection of HP 3PAR storage – One of the major drawbacks for block-mode storage with blades has always been the cost of the SAN to connect it to the blade enclosure. With the ability to connect an HP 3PAR storage array directly to the c-Class enclosure without any SAN components, HP has reduced both the cost and the complexity of storage for a wide class of applications that have storage requirements within the scope of a single storage array.
New blades – With this announcement, HP fills in the gaps in their blade portfolio, announcing a new Intel Xeon EN based BL-420 for entry requirements, an upgrade to the BL-465 to support the latest AMD 16-core Interlagos CPU, and the BL-660, a new single-width Xeon E5 based 4-socket blade. In addition, HP has expanded the capacity of the sidecar storage blade to 1.5 TB, enabling an 8-server and 12 TB + chassis configuration.
I said last year that this would happen sometime in the first half of this year, but for some reason my colleagues and clients have kept asking me exactly when we would see a real ARM server running a real OS. How about now?
To copy from Calxeda’s most recent blog post:
“This week, Calxeda is showing a live Calxeda cluster running Ubuntu 12.04 LTS on real EnergyCore hardware at the Ubuntu Developer and Cloud Summit events in Oakland, CA. … This is the real deal; quad-core, w/ 4MB cache, secure management engine, and Calxeda’s fabric all up and running.”
This is a significant milestone for many reasons. It proves that Calxeda can indeed deliver a working server based on its scalable fabric architecture, although having HP signing up as a partner meant that this was essentially a non-issue, but still, proof is good. It also establishes that at least one Linux distribution provider, in this case Ubuntu, is willing to provide a real supported distribution. My guess is that Red Hat and Centos will jump on the bus fairly soon as well.
Most importantly, we can get on with the important work of characterizing real benchmarks on real systems with real OS support. HP’s discovery centers will certainly play a part in this process as well, and I am willing to bet that by the end of the summer we will have some compelling data on whether the ARM server will deliver on its performance and energy efficiency promises. It’s not a slam dunk guaranteed win – Intel has been steadily ratcheting up its energy efficiency, and the latest generation of x86 server from HP, IBM, Dell, and others show promise of much better throughput per watt than their predecessors. Add to that the demonstration of a Xeon-based system by Sea Micro (ironically now owned by AMD) that delivered Xeon CPUs at a 10 W per CPU power overhead, an unheard of efficiency.
Over the last couple of years, IBM, despite having a rich internal technology ecosystem and a number of competitive blade and CI offerings, has not had a comprehensive integrated offering to challenge HP’s CloudSystem Matrix and Cisco’s UCS. This past week IBM effectively silenced its critics and jumped to the head of the CI queue with the announcement of two products, PureFlex and PureApplication, the results of a massive multi-year engineering investment in blade hardware, systems management, networking, and storage integration. Based on a new modular blade architecture and new management architecture, the two products are really more of a continuum of a product defined by the level of software rather than two separate technology offerings.
PureFlex is the base product, consisting of the new hardware (which despite having the same number of blades as the existing HS blade products, is in fact a totally new piece of hardware), which integrates both BNT-based networking as well as a new object-based management architecture which can manage up to four chassis and provide a powerful setoff optimization, installation, and self-diagnostic functions for the hardware and software stack up to and including the OS images and VMs. In addition IBM appears to have integrated the complete suite of Open Fabric Manager and Virtual Fabric for remapping MAC/WWN UIDs and managing VM networking connections, and storage integration via the embedded V7000 storage unit, which serves as both a storage pool and an aggregation point for virtualizing external storage. The laundry list of features and functions is too long to itemize here, but PureFlex, especially with its hypervisor-neutrality and IBM’s Cloud FastStart option, is a complete platform for an enterprise private cloud or a horizontal VM compute farm, however you choose to label a shared VM utility.
Today, after two of its largest partners have already announced their systems portfolios that will use it, Intel finally announced one of the worst-kept secrets in the industry: the Xeon E5-2600 family of processors.
OK, now that I’ve got in my jab at the absurdity of the announcement scheduling, let’s look at the thing itself. In a nutshell, these new processors, based on the previous-generation 32 nm production process of the Xeon 5600 series but incorporating the new “Sandy Bridge” architecture, are, in fact, a big deal. They incorporate several architectural innovations and will bring major improvements in power efficiency and performance to servers. Highlights include:
Performance improvements on selected benchmarks of up to 80% above the previous Xeon 5600 CPUs, apparently due to both improved CPU architecture and larger memory capacity (up to 24 DIMMs at 32 GB per DIMM equals a whopping 768 GB capacity for a two-socket, eight-core/socket server).
Improved I/O architecture, including an on-chip PCIe 3 controller and a special mode that allows I/O controllers to write directly to the CPU cache without a round trip to memory — a feature that only a handful of I/O device developers will use, but one that contributes to improved I/O performance and lowers CPU overhead during PCIe I/O.
Significantly improved energy efficiency, with the SPECpower_ssj2008 benchmark showing a 50% improvement in performance per watt over previous models.
Last week it was Dell’s turn to tout its new wares, as it pulled back the curtain on its 12th-eneration servers and associated infrastructure. I’m still digging through all the details, but at first glance it looks like Dell has been listening to a lot of the same customer input as HP, and as a result their messages (and very likely the value delivered) are in many ways similar. Among the highlights of Dell’s messaging are:
Faster provisioning with next-gen agentless intelligent controllers — Dell’s version is iDRAC7, and in conjunction with its LifeCyle Controller firmware, Dell makes many of the same claims as HP, including faster time to provision and maintain new servers, automatic firmware updates, and many fewer administrative steps, resulting in opex savings.
Intelligent storage tiering and aggressive use of flash memory, under the aegis of Dell’s “Fluid Storage” architecture, introduced last year.
A high-profile positioning for its Virtual Network architecture, building on its acquisition of Force10 Networks last year. With HP and now Dell aiming for more of the network budget in the data center, it’s not hard to understand why Cisco was so aggressive in pursuing its piece of the server opportunity — any pretense of civil coexistence in the world of enterprise networks is gone, and the only mutual interest holding the vendors together is their customers’ demand that they continue to play well together.
At its recent financial analyst day, AMD indicated that it intended to differentiate itself by creating products that were advantaged in niche markets, with specific mention, among other segments, of servers, and to generally shake up the trench warfare that has had it on the losing side of its lifelong battle with Intel (my interpretation, not AMD management’s words). Today, at least for the server side of the business AMD made a move that can potentially offer it visibility and differentiation by acquiring innovative server startup SeaMicro.
SeaMicro has attracted our attention since its appearance (blog post 1, blog post 2), with its innovative architecture that dramatically reduces power and improves density by sharing components like I/O adapters, disks, and even BIOS over a proprietary fabric. The irony here is that SeaMicro came to market with a tight alignment with Intel, who at one point even introduced a special dual-core packaging of its Atom CPU to allow SeaMicro to improve its density and power efficiency. Most recently SeaMicro and Intel announced a new model that featured Xeon CPUs to address the more mainstream segments that were not for SeaMicro’s original Atom-based offering.
On Monday, February 13, HP announced its next turn of the great wheel for servers with the announcement of its Gen8 family of servers. Interestingly, since the announcement was ahead of Intel’s official announcement of the supporting E5 server CPUs, HP had absolutely nothing to say about the CPUs or performance of these systems. But even if the CPU information had been available, it would have been a sideshow to the main thrust of the Gen8 launch — improving the overall TCO (particularly Opex) of servers by making them more automated, more manageable, and easier to remediate when there is a problem, along with enhancements to storage, data center infrastructure management (DCIM) capabilities, and a fundamental change in the way that services and support are delivered.
With a little more granularity, the major components of the Gen8 server technology announcement included:
Onboard Automation – A suite of capabilities and tools that provide improved agentless local intelligence to allow quicker and lower labor cost provisioning, including faster boot cycles, “one click” firmware updates of single or multiple systems, intelligent and greatly improved boot-time diagnostics, and run-time diagnostics. This is apparently implemented by more powerful onboard management controllers and pre-provisioning a lot of software on built-in flash memory, which is used by the onboard controller. HP claims that the combination of these tools can increase operator productivity by up to 65%. One of the eye-catching features is an iPhone app that will scan a code printed on the server and go back through the Insight Management Environment stack and trigger the appropriate script to provision the server.[i]Possibly a bit of a gimmick, but a cool-looking one.
In late 2010 I noted that startup SeaMicro had introduced an ultra-dense server using Intel Atom chips in an innovative fabric-based architecture that allowed them to factor out much of the power overhead from a large multi-CPU server ( http://blogs.forrester.com/richard_fichera/10-09-21-little_servers_big_applications_intel_developer_forum). Along with many observers, I noted that the original SeaMicro server was well-suited to many light-weight edge processing tasks, but that the system would not support more traditional compute-intensive tasks due to the performance of the Atom core. I was, however, quite taken with the basic architecture, which uses a proprietary high-speed (1.28 Tb/s) 3D mesh interconnect to allow the CPU cores to share network, BIOS and disk resources that are normally replicated on a per-server in conventional designs, with commensurate reductions in power and an increase in density.
OK, it’s time to stretch the 2012 writing muscles, and what better way to do it than with the time honored “retrospective” format. But rather than try and itemize all the news and come up with a list of maybe a dozen or more interesting things, I decided instead to pick the best and the worst – events and developments that show the amazing range of the technology business, its potentials and its daily frustrations. So, drum roll, please. My personal nomination for the best and worst of the year (along with a special extra bonus category) are:
The Best – IBM Watson stomps the world’s best human players in Jeopardy. In early 2011, IBM put its latest deep computing project, Watson, up against some of the best players in the world in a game of Jeopardy. Watson, consisting of hundreds of IBM Power CPUs, gazillions of bytes of memory and storage, and arguably the most sophisticated rules engine and natural language recognition capability ever developed, won hands down. If you haven’t seen the videos of this event, you should – seeing the IBM system fluidly answer very tricky questions is amazing. There is no sense that it is parsing the question and then sorting through 200 – 300 million pages of data per second in the background as it assembles its answers. This is truly the computer industry at its best. IBM lived up to its brand image as the oldest and strongest technology company and showed us a potential for integrating computers into untapped new potential solutions. Since the Jeopardy event, IBM has been working on commercializing Watson with an eye toward delivering domain-specific expert advisors. I recently listened to a presentation by a doctor participating in the trials of a Watson medical assistant, and the results were startling in terms of the potential to assist medical professionals in diagnostic procedures.
Today HP announced a new set of technology programs and future products designed to move x86 server technology for both Windows and Linux more fully into the realm of truly mission-critical computing. My interpretation of these moves is that it is both a combined defensive and pro-active offensive action on HP’s part that will both protect them as their Itanium/HP-UX portfolio slowly declines as well as offer attractive and potentially unique options for both current and future customers who want to deploy increasingly critical services on x86 platforms.
Bearing in mind that the earliest of these elements will not be in place until approximately mid-2012, the key elements that HP is currently disclosing are:
ServiceGuard for Linux – This is a big win for Linux users on HP, and removes a major operational and architectural hurdle for HP-UX migrations. ServiceGuard is a highly regarded clustering and HA facility on HP-UX, and includes many features for local and geographically distributed HA. The lack of ServiceGuard is often cited as a risk in HP-UX migrations. The availability of ServiceGuard by mid-2012 will remove yet another barrier to smooth migration from HP-UX to Linux, and will help make sure that HP retains the business as it migrates from HP-UX.
Analysis engine for x86 – Analysis engine is internal software that provides system diagnostics, predictive failure analysis and self-repair on HP-UX systems. With an uncommitted delivery date, HP will port this to selected x86 servers. My guess is that since the analysis engine probably requires some level of hardware assist, the analysis engine will be paired with the next item on the list…
