ARM-Based Servers – Looming Tsunami Or Just A Ripple In The Industry Pond?

Richard Fichera

From nothing more than an outlandish speculation, the prospects for a new entrant into the volume Linux and Windows server space have suddenly become much more concrete, culminating in an immense buzz at CES as numerous players, including NVIDIA and Microsoft, stoked the fires with innuendo, announcements, and demos.

Consumers of x86 servers are always on the lookout for faster, cheaper, and more power-efficient servers. In the event that they can’t get all three, the combination of cheaper and more energy-efficient seems to be attractive to a large enough chunk of the market to have motivated Intel, AMD, and all their system partners to develop low-power chips and servers designed for high density compute and web/cloud environments. Up until now the debate was Intel versus AMD, and low power meant a CPU with four cores and a power dissipation of 35 – 65 Watts.

The Promised Land

The performance trajectory of processors that were formerly purely mobile device processors, notably the ARM Cortex, has suddenly introduced a new potential option into the collective industry mindset. But is this even a reasonable proposition, and if so, what does it take for it to become a reality?

Our first item of business is to figure out whether or not it even makes sense to think about these CPUs as server processors. My quick take is yes, with some caveats. The latest ARM offering is the Cortex A9, with vendors offering dual core products at up to 1.2 GHz currently (the architecture claims scalability to four cores and 2 GHz). It draws approximately 2W, much less than any single core x86 CPU, and a multi-core version should be able to execute any reasonable web workload. Coupled with the promise of embedded GPUs, the notion of a server that consumes much less power than even the lowest power x86 begins to look attractive. But…

Intel Announces Sandy Bridge. A Big Deal? You Bet!

Richard Fichera

Intel today officially announced the first products based on the much-discussed Sandy Bridge CPU architecture, and first impressions are highly favorable, with my take being that Sandy Bridge represents the first step in a very aggressive product road map for Intel in 2011.

Sandy Bridge is the next architectural spin after Intel’s Westmere shrink of the predecessor Nehalem architecture (the “tick” in Intel’s famous “tick-tock” progression of architectural changes followed by process shrink) and incorporates some major innovations compared to the previous architecture:

  • Minor but in toto significant changes to many aspects of the low-level microarchitecture – more registers, better prefetch, changes to the way instructions and operands are decode, cached and written back to registers and cache.
  • Major changes in integration of functions on the CPU die – Almost all major subsystems, including CPU, memory controller, graphics controller and PCIe controller, are now integrated onto the same die, along with the ability to share data with much lower latency than in previous generations. In addition to more efficient data sharing, this level of integration allows for better power efficiency.
  • Improvements to media processing – A dedicated video transcoding engine and an extended vector instruction set for media and floating point calculations improves Sandy Bridge capabilities in several major application domains.

IPv6: Drive Innovation With Rewards, Not Fear

Andre Kindness

I’m a sucker for good, biting humor, and in the spirit of Stephen Colbert’s Medals of Fear that he gave to a few distinguished souls (the press, Mark Zuckerberg, Anderson Cooper) at the rally in Washington D.C., I would like to hand a medal to the U.S. State Department for its 1999 publication of a country-by-country set of "Y2K" warnings — “End of Days” scenarios and solutions — for Americans doing business in 194 nations. I would give another medal to IPv6, the most drawn-out killer technology to date — and one that has had the longest run at trying to scare everyone about the end of IPv4. At Forrester, we are starting to see the adoption freighter slowly turning via the number of inquiries rolling in; governments accelerating their adoption with new mandates; vendors including IPv6 in their solutions; and the Number Resource Organization escalating its announcements about the depletion of IPv4 addresses (only 5% left!). To add to the drama, vendors are in the process of creating IPv4 address countdown clocks to generate buzz and differentiation. These scare tactics haven’t worked because technology pundits haven’t spoken about IPv6 in business terms. There is enormous business value in IPv6; those who embrace it will be the new leaders in their space.

HP's Acquisition Of Palm: InfoWorld Should Read Its Own Articles

Tom Grant

Within 24 hours, InfoWorld published two seemingly unrelated articles. One covered HP's announcement of its intent to acquire Palm, which led people to speculate aloud, "What the heck were they thinking?" The first part of the article spent a couple of paragraphs musing about how this move might or might not help HP's interest in the slate computer market. The path from acquiring Palm to becoming an iPad competitor isn't very clear, however, so maybe the real point has nothing to do with slate computers. We can't get enough of talking about slate computers, but what if Palm's products have some potential connection to HP's existing portfolio? Crazy idea, I know.

The next day, InfoWorld published another article with the acidic headline, "Smartphone management becoming a nightmare":

Smartphones and mobile devices are becoming a nightmare for IT shops to manage, with users carrying multiple types of phones with different operating systems and expecting access to email, video-conferencing, and various types of corporate applications.

In other words, IT departments struggling with these standardization efforts might want to talk to a company that can help. Say, someone with a lot of products and services for solution areas like cloud computing, application transformation, portfolio and asset management. It'd be great if said vendor had mobile technology that factored into these larger IT infrastructure concerns.

Oh, yeah...
