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
In the good old days, computer industry trade shows were bigger than life events – booths with barkers and actors, ice cream and espresso bars and games in the booth, magic acts and surging crowds gawking at technology. In recent years, they have for the most part become sad shadows of their former selves. The great SHOWS are gone, replaced with button-down vertical and regional events where you are lucky to get a pen or a miniature candy bar for your troubles.
Enter Oracle OpenWorld. Mix 45,000 people, hundreds of exhibitors, one of the world’s largest software and systems company looking to make an impression, and you have the new generation of technology extravaganza. The scale is extravagant, taking up the entire Moscone Center complex (N, S and W) along with a couple of hotel venues, closing off a block of a major San Francisco street for a week, and throwing a little evening party for 20 or 30 thousand people.
But mixed with the hoopla, which included wheel of fortune giveaways that had hundreds of people snaking around the already crowded exhibition floor in serpentine lines, mini golf and whack-a-mole-games in the exhibit booths along with the aforementioned espresso and ice cream stands, there was genuine content and the public face of some significant trends. So far, after 24 hours, some major messages come through loud and clear:
I just attended IDF and I’ve got to say, Intel has certainly gotten the cloud message. Almost everything is centered on clouds, from the high-concept keynotes to the presentations on low-level infrastructure, although if you dug deep enough there was content for general old-fashioned data center and I&O professionals. Some highlights:
Chips and processors and low-level hardware
Intel is, after all, a semiconductor foundry, and despite their expertise in design, their true core competitive advantage is their foundry operations – even their competitors grudgingly acknowledge that they can manufacture semiconductors better than anyone else on the planet. As a consequence, showing off new designs and processes is always front and center at IDF, and this year was no exception. Last year it was Sandy Bridge, the 22nm shrink of the 32nm Westmere (although Sandy Bridge also incorporated some significant design improvements). This year it was Ivy Bridge, the 22nm “tick” of the Intel “tick-tock” design cycle. Ivy Bridge is the new 22nm architecture and seems to have inherited Intel’s recent focus on power efficiency, with major improvements beyond the already solid advantages of their 22nm process, including deeper P-States and the ability to actually shut down parts of the chip when it is idle. While they did not discuss the server variants in any detail, the desktop versions will get an entirely new integrated graphics processor which they are obviously hoping will blunt AMD’s resurgence in client systems. On the server side, if I were to guess, I would guess more cores and larger caches, along with increased support for virtualization of I/O beyond what they currently have.
