With a couple of months' perspective, I’m pretty convinced that Intel has made a potentially disruptive entry in the market for programmable computational accelerators, often referred to as GPGPUs (General Purpose Graphics Processing Units) in deference to the fact that the market leaders, NVIDIA and AMD, have dominated the segment with parallel computational units derived from high-end GPUs. In late 2012, Intel, referring to the architecture as MIC (Many Independent Cores) introduced the Xeon Phi product, the long-awaited productization of the development project that was known internally (and to the rest of the world as well) as Knight’s Ferry, a MIC coprocessor with up to 62 modified Xeon cores implemented in its latest 22 nm process.
On Tuesday November 8, after more than a year of pre-announcement disclosures that eventually left very little to the imagination, Intel finally announced the Itanium 9500, formerly known as Poulson. Added to this was the big surprise of HP announcing a refresh of its current line of Integrity servers, from blades to the large Superdome servers, with the new Itanium 9500.
As noted in an earlier post, the Itanium 9500 offers considerable performance improvements over its predecessors, and instantiated in HP’s new Integrity line it is positioned as delivering between 2X and 3X the performance per socket as previous Itanium 9300 (Tukwilla) systems at approximately the same price. For those remaining committed to Itanium and its attendant OS platforms, notably HP-UX, this is unmitigated good news. The fly in the ointment (I have never seen a fly in any ointment, but it does sound gross), of course, is HP’s dispute with Oracle. Despite the initial judgment in HP’s favor, the trial is a) not over yet, and b) Oracle has already filed for an early appeal of the initial verdict, which would ordinarily have to wait until the second phase of the trial, scheduled for next year, to finish. The net takeaway is that Oracle’s future availability on Itanium and HP-UX is not yet assured, so we really cannot advise the large number of Oracle users who will require Oracle 12 and later versions to relax yet.
Earlier this week, in conjunction with ARM Holdings plc’s announcement of the upcoming Cortex A53 and A57, full 64-bit CPU implementations based on the ARM V8 specification, AMD also announced that it would be designing and selling SOC (System On a Chip) products based on this technology in 2014, roughly coinciding with availability of 64-bit parts from ARM and other partners.
This is a major event in the ARM ecosystem. AMD, while much smaller than Intel, is still a multi-billion-dollar enterprise, and for the second largest vendor of x86 chips to also throw its hat into the ARM ecosystem and potentially compete with its own mainstream server and desktop CPU business is an aggressive move on the part of AMD management that carries some risk and much potential advantage.
Reduced to its essentials, what AMD announced (and in some cases hinted at):
Intention to produce A53/A57 SOC modules for multiple server segments. There was no formal statement of intentions regarding tablet/mobile devices, but it doesn’t take a rocket scientist to figure out that AMD wants a piece of this market, and ARM is a way to participate.
The announcement is wider that just the SOC silicon. AMD also hinted at making a range of IP, including its fabric architecture from the SeaMicro architecture, available in the form of “reusable IP blocks.” My interpretation is that it intends to make the fabric, reference architectures, and various SOCs available to its hardware system partners.
[For some reason this has been unpublished since April — so here it is well after AMD announced its next spin of the SeaMicro product.]
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, it 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 a part of SeaMicro’s original Atom-based offering.
Every culture has its coming of age rituals — Confirmation, Bar Mitzvah, being hunted by tribal elders, surviving in the wilderness, driving at high speed while texting — all of which mark the progress from childhood to adulthood. In the high-tech world, one of the rituals marking the maturation of a company is the user group. When a company has a strategy it wants to communicate, a critical mass of customers, and prospects bright enough that it wants to highlight them rather than obscure them, it is time for a user group meeting.
This year, having passed a year since the acquisition of Novell by AttachMate and its subsequent instantiation as a standalone division, as well as being its 20th anniversary, SUSE had its first user group meeting. All in all, the portents were good, and SUSE got its core messages across to an audience of about 500 of its users as well as a cadre of the more sophisticated (IMHO) industry analysts.
Among My Key Takeaways:
SUSE is a stable company with rational management — With profitable revenues of over $200M and a publicly stated plan to hit $234 for the next fiscal year, SUSE is a reasonably sized company (technically a division of $1.3B Attachmate, but it looks and acts like an independent company), with growth rates that look to be a couple of points higher than its segment.
SUSE’s management has done an excellent job of focusing the company — SUSE, acknowledging its size disadvantage over competitor Red Hat, has chosen to focus heavily on enterprise Linux, publicly disavowing desktop and mobile device directions. SUSE’s claim is that their market share in the core enterprise segment is larger than their overall market share compared to Red Hat. This is a hard number to even begin to tweeze out, but it feels like a reasonable claim.
This week the California courts handed down a nice present for HP — a verdict confirming that Oracle was required to continue to deliver its software on HP’s Itanium-based Integrity servers. This was a major victory for HP, on the face of it giving them the prize they sought — continued availability of Oracle’s eponymous database on their high-end systems.
However, HP’s customers should not immediately assume that everything has returned to a “status quo ante.” Once Humpty Dumpty has fallen off the wall it is very difficult to put the pieces together again. As I see it, there are still three major elephants in the room that HP users must acknowledge before they make any decisions:
Oracle will appeal, and there is no guarantee of the outcome. The verdict could be upheld or it could be reversed. If it is upheld, then that represents a further delay in the start date from which Oracle will be measured for its compliance with the court ordered development. Oracle will also continue to press its counterclaims against HP, but those do not directly relate to the continued development or Oracle software on Itanium.
Itanium is still nearing the end of its road map. A reasonable interpretation of the road map tea leaves that have been exposed puts the final Itanium release at about 2015 unless Intel decides to artificially split Kittson into two separate releases. Integrity customers must take this into account as they buy into the architecture in the last few years of Itanium’s life, although HP can be depended on to offer high-quality support for a decade after the last Itanium CPU rolls off Intel’s fab lines. HP has declared its intention to produce Integrity-level x86 systems, but OS support intentions are currently stated as Linux and Windows, not HP-UX.
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.
Earlier this week Dell joined arch-competitor HP in endorsing ARM as a potential platform for scale-out workloads by announcing “Copper,” an ARM-based version of its PowerEdge-C dense server product line. Dell’s announcement and positioning, while a little less high-profile than HP’s February announcement, is intended to serve the same purpose — to enable an ARM ecosystem by providing a platform for exploring ARM workloads and to gain a visible presence in the event that it begins to take off.
Dell’s platform is based on a four-core Marvell ARM V7 SOC implementation, which it claims is somewhat higher performance than the Calxeda part, although drawing more power, at 15W per node (including RAM and local disk). The server uses the PowerEdge-C form factor of 12 vertically mounted server modules in a 3U enclosure, each with four server nodes on them for a total of 48 servers/192 cores in a 3U enclosure. In a departure from other PowerEdge-C products, the Copper server has integrated L2 network connectivity spanning all servers, so that the unit will be able to serve as a low-cost test bed for clustered applications without external switches.
Dell is offering this server to selected customers, not as a GA product, along with open source versions of the LAMP stack, Crowbar, and Hadoop. Currently Cannonical is supplying Ubuntu for ARM servers, and Dell is actively working with other partners. Dell expects to see OpenStack available for demos in May, and there is an active Fedora project underway as well.
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.
In the latest evolution of its Linux push, IBM has added to its non-x86 Linux server line with the introduction of new dedicated Power 7 rack and blade servers that only run Linux. “Hah!” you say. “Power already runs Linux, and quite well according to IBM.” This is indeed true, but when you look at the price/performance of Linux on standard Power, the picture is not quite as advantageous, with the higher cost of Power servers compared to x86 servers offsetting much if not all of the performance advantage.
Enter the new Flex System p24L (Linux) Compute Node blade for the new PureFlex system and the IBM PowerLinuxTM 7R2 rack server. Both are dedicated Linux-only systems with 2 Power 7 6/8 core, 4 threads/core processors, and are shipped with unlimited licenses for IBM’s PowerVM hypervisor. Most importantly, these systems, in exchange for the limitation that they will run only Linux, are priced competitively with similarly configured x86 systems from major competitors, and IBM is betting on the improvement in performance, shown by IBM-supplied benchmarks, to overcome any resistance to running Linux on a non-x86 system. Note that this is a different proposition than Linux running on an IFL in a zSeries, since the mainframe is usually not the entry for the customer — IBM typically sells to customers with existing mainframe, whereas with Power Linux they will also be attempting to sell to net new customers as well as established accounts.
