Microservers, designed for specific workloads, low power, and tight spaces, are widely thought to be the future of the data center. The disagreements come when you start talking timelines.
Like most new technologies, the enthusiasm for new developments usually outpaces the revolution. Fifteen years ago, Linux was going to take over the world. Today, Linux is everywhere and no one blinks when a company builds on an open source stack.
Microservers may be the same way. But this revolution will take some time to play out. In our microserver special report, Nick Heath noted that microservers, ARM and Intel-based, are being used for specific workloads such as serving Web content, but enterprises are all about multipurpose computing for a wide range of applications.
In other words, microservers won't be pushing their cousins out the door anytime soon. However, new computing tasks may change that equation. Heath wrote:
The range of workloads handled by microservers is broadening. The first generation was focused on relatively CPU-light tasks, such as serving static elements on web pages, but the second generation employed a wider range of more powerful (but still energy-frugal) SoCs — and, importantly, added support for 64-bit processing and more memory. This expanded microservers' capabilities to tasks such as serving dynamic web elements (those updated by AJAX, for example), serving hosted desktops, and digital signal processing for telcos.
Errol Rasit, research director for data center dynamics at Gartner, said the number of tasks suited to being scaled across microserver clusters would continue to grow as new workloads, such as big data analytics, emerge.
In January, Frank Frankovsky, president of the OCP and Facebook's hardware design lead, said that ARM processors will take over the data center as they rode the microserver wave. He also said his prognostication was a bit optimistic and off six months to a year. Three months have passed since Frankovsky said that and the ARM developments haven't exactly snowballed. He may be off by a few more years.
There's little doubt, however, that Frankovsky is on to something.
The spectrum of workloads that microservers can carry out is increasing, as more enterprises take on tasks that can be distributed across microserver clusters and processed in parallel, such as big data analytics. Microservers also provide an alternate platform for executing specialist jobs previously restricted to high-cost proprietary technology, such as digital signal processing. And as the capabilities of the low-power chipsets underpinning microservers grow, more tasks will become possible using the platform.
Whether ARM, AMD, or Intel lead the microserver charge remains to be seen, but the revolution will happen. It'll just take a bit more time than you thought. IT buyers need to stay on top of microserver developments, experiment when possible and then plot larger installations as workloads evolve.
