Recently we’ve had a chance to look again at two very conflicting views from HP and Facebook on how to do web-scale and cloud computing, both announced at the recent OCP annual event in California.
From HP come its new CloudLine systems, the public face of their joint venture with Foxcon. Early details released by HP show a line of cost-optimized servers descended from a conventional engineering lineage and incorporating selected bits of OCP technology to reduce costs. These are minimalist rack servers designed, after stripping away all the announcement verbiage, to compete with white-box vendors such as Quanta, SuperMicro and a host of others. Available in five models ranging from the minimally-featured CL1100 up through larger nodes designed for high I/O, big data and compute-intensive workloads, these systems will allow large installations to install capacity at costs ranging from 10 – 25% less than the equivalent capacity in their standard ProLiant product line. While the strategic implications of HP having to share IP and market presence with Foxcon are still unclear, it is a measure of HP’s adaptability that they were willing to execute on this arrangement to protect against inroads from emerging competition in the most rapidly growing segment of the server market, and one where they have probably been under immense margin pressure.
Intel has made no secret of its development of the Xeon D, an SOC product designed to take Xeon processing close to power levels and product niches currently occupied by its lower-power and lower performance Atom line, and where emerging competition from ARM is more viable.
The new Xeon D-1500 is clear evidence that Intel “gets it” as far as platforms for hyperscale computing and other throughput per Watt and density-sensitive workloads, both in the enterprise and in the cloud are concerned. The D1500 breaks new ground in several areas:
It is the first Xeon SOC, combining 4 or 8 Xeon cores with embedded I/O including SATA, PCIe and multiple 10 nd 1 Gb Ethernet ports.
It is the first of Intel’s 14 nm server chips expected to be introduced this year. This expected process shrink will also deliver a further performance and performance per Watt across the entire line of entry through mid-range server parts this year.
Why is this significant?
With the D-1500, Intel effectively draws a very deep line in the sand for emerging ARM technology as well as for AMD. The D1500, with 20W – 45W power, delivers the lower end of Xeon performance at power and density levels previously associated with Atom, and close enough to what is expected from the newer generation of higher performance ARM chips to once again call into question the viability of ARM on a pure performance and efficiency basis. While ARM implementations with embedded accelerators such as DSPs may still be attractive in selected workloads, the availability of a mainstream x86 option at these power levels may blunt the pace of ARM design wins both for general-purpose servers as well as embedded designs, notably for storage systems.
I'm at IDF, a major geekfest for the people interested in the guts of today’s computing infrastructure, and will be immersing myself in the flow for a couple of days. Before going completely off the deep end, I wanted to call out the announcement of the new Xeon E5. While I’ve discussed it in more depth in an accompanying Quick Take just published on our main website, I wanted to add some additional comments on its implications for data center operations, particularly in the areas of capacity planning and long-term capital budgeting.
For many years, each successive iteration of Intel’s and partners’ roadmaps has been quietly delivering a major benefit that seldom gets top billing – additional capacity within the same power and physical footprint, and the resulting ability for users from small enterprises to mega-scale service providers, to defer additional data spending capital expense.
Last month I attended Huawei’s annual Global Analyst Summit, for the requisite several days of mass presentations, executive meetings and tours that typically constitute such an event. Underneath my veneer of blasé cynicism, I was actually quite intrigued, since I really knew very little about Huawei. And what I did know was tainted by popular and persistent negatives – they were the ones who supposedly copied Cisco’s IP to get into the network business, and, until we got better acquainted with our own Federal Government’s little shenanigans, Huawei was the big bad boogie man who was going to spy on us with every piece of network equipment they installed.
Reality was quite a bit different. Ancient disputes about IP aside, I found a $40B technology powerhouse who is probably the least-known and understood company of its size in the world, and one which appears poised to pose major challenges to incumbents in several areas, including mainstream enterprise IT.
So you don’t know Huawei
First, some basics. Huawei’s 2013 revenue was $39.5 Billion, which puts it right up there with some much better-known names such as Lenovo, Oracle, Dell and Cisco.
It’s been a long wait, about four years if memory serves me well, since Intel introduced the Xeon E7, a high-end server CPU targeted at the highest performance per-socket x86, from high-end two socket servers to 8-socket servers with tons of memory and lots of I/O. In the ensuing four years (an eternity in a world where annual product cycles are considered the norm), subsequent generations of lesser Xeons, most recently culminating in the latest generation 22 nm Xeon E5 V2 Ivy Bridge server CPUs, have somewhat diluted the value proposition of the original E7.
So what is the poor high-end server user with really demanding single-image workloads to do? The answer was to wait for the Xeon E7 V2, and at first glance, it appears that the wait was worth it. High-end CPUs take longer to develop than lower-end products, and in my opinion Intel made the right decision to skip the previous generation 22nm Sandy Bridge architecture and go to Ivy Bridge, it’s architectural successor in the Intel “Tick-Tock” cycle of new process, then new architecture.
What was announced?
The announcement was the formal unveiling of the Xeon E7 V2 CPU, available in multiple performance bins with anywhere from 8 to 15 cores per socket. Critical specifications include:
Up to 15 cores per socket
24 DIMM slots, allowing up to 1.5 TB of memory with 64 GB DIMMs
Approximately 4X I/O bandwidth improvement
New RAS features, including low-level memory controller modes optimized for either high-availability or performance mode (BIOS option), enhanced error recovery and soft-error reporting
As the new year looms, thoughts turn once again to our annual reading of the tea leaves, in this case focused on what I see coming in server land. We’ve just published the full report, Predictions for 2014: Servers & Data Centers, but as teaser, here are a few of the major highlights from the report:
1. Increasing choices in form factor and packaging – I&O pros will have to cope with a proliferation of new form factors, some optimized for dense low-power cloud workloads, some for general purpose legacy IT, and some for horizontal VM clusters (or internal cloud if you prefer). These will continue to appear in an increasing number of variants.
2. ARM – Make or break time is coming, depending on the success of coming 64-bit ARM CPU/SOC designs with full server feature sets including VM support.
3. The beat goes on – Major turn of the great wheel coming for server CPUs in early 2014.
4. Huge potential disruption in flash architecture – Introduction of flash in main memory DIMM slots has the potential to completely disrupt how flash is used in storage tiers, and potentially can break the current storage tiering model, initially physically with the potential to ripple through memory architectures.
In his 1956 dystopian sci-fi novel “The City and the Stars”, Arthur C. Clarke puts forth the fundamental design tenet for making eternal machines, “A machine shall have no moving parts”. To someone from the 1950s current computers would appear to come close to that ideal – the CPUs and memory perform silent magic and can, with some ingenuity, be passively cooled, and invisible electronic signals carry information in and out of them to networks and … oops, to rotating disks, still with us after more than five decades[i]. But, as we all know, salvation has appeared on the horizon in the form of solid-state storage, so called flash storage (actually an idea of several decades standing as well, just not affordable until recently).
The initial substitution of flash for conventional storage yields immediate gratification in the form of lower power, maybe lower cost if used effectively, and higher performance, but the ripple effect benefits of flash can be even more pervasive. However, the implementation of the major architectural changes engendered across the whole IT stack by the use of flash is a difficult conceptual challenge for users and largely addressed only piecemeal by most vendors. Enter IBM and its Flashahead initiative.
What is Happening?
On Friday, April 11, IBM announced a major initiative, to the tune of a spending commitment of $1B, to accelerate the use of flash technology by means of three major programs:
· Fundamental flash R&D
· New storage products built on flash-only memory technology
With the next major spin of Intel server CPUs due later this year, HP’s customers have been waiting for HP’s next iteration of its core c-Class BladeSystem, which has been on the market for almost 7 years without any major changes to its basic architecture. IBM made a major enhancement to its BladeCenter architecture, replacing it with the new Pure Systems, and Cisco’s offering is new enough that it should last for at least another three years without a major architectural refresh, leaving HP customers to wonder when HP was going to introduce its next blade enclosure, and whether it would be compatible with current products.
At their partner conference this week, HP announced a range of enhancements to its blade product line that on combination represent a strong evolution of the current product while maintaining compatibility with current investments. This positioning is similar to what IBM did with its BladeCenter to BladeCenter-H upgrade, preserving current customer investment and extending the life of the current server and peripheral modules for several more years.
Tech Stuff – What Was Announced
Among the goodies announced on February 19 was an assortment of performance and functionality enhancements, including:
Platinum enclosure — The centerpiece of the announcement was the new c7000 Platinum enclosure, which boosts the speed of the midplane signal paths from 10 GHz to 14GHz, for an increase of 40% in raw bandwidth of the critical midplane, across which all of the enclosure I/O travels. In addition to the increased bandwidth midplane, the new enclosure incorporates location aware sensors and also doubles the available storage bandwidth.
So what does VMware and EMC’s announcement of the new Pivotal Initiative mean for I&O leaders? Put simply, it means the leading virtualization vendor is staying focused on the data center — and that’s good news. As many wise men have said, the best strategy comes from knowing what NOT to do. In this case, that means NOT shifting focus too fast and too far afield to the cloud.
I think this is a great move, and makes all kinds of sense to protect VMware’s relationship with its core buyer, maintain focus on the datacenter, and lay the foundation for the vendor’s software-defined data center strategy. This move helps to end the cloud-washing that’s confused customers for years: There’s a lot of work left to do to virtualize the entire data center stack, from compute to storage and network and apps, and the easy apps, by now, have mostly been virtualized. The remaining workloads enterprises seek to virtualize are much harder: They don’t naturally benefit from consolidation savings, they are highly performance sensitive, and they are much more complex.
[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.
