Solid-state storage showing up in more shops
Cloud storage might be experiencing some growing pains, but solid-state storage appears well on its way to becoming a data center mainstay. Slightly more than 16% are using solid-state storage now, representing a year-over-year gain of nearly six percentage points. Another 10.5% said they’ll implement solid-state this year (vs. last year’s 5.9%). And one-third will evaluate the technology in 2011, leaving only 40% without any specific solid-state storage plans.

On average, current solid-state users have 6.8 TB of the stuff installed, which is a pretty impressive figure when you consider the cost of solid-state. Those who said they’ll be adding solid-state storage this year will be upping their installed capacity by an average of 5.9 TB.
Most of that solid-state storage (75%) is finding its way into arrays; that option has emerged as the preferred implementation choice. Thirty percent -- much of which likely represents solid-state in PCIe form factors -- is installed in servers, and another 27% of solid-state storage is used in laptops and desktop PCs.
Striving toward efficiency
“Efficiency” has become the byword of many storage shops over the last few years, not because it has a catchy marketing ring, but because a shifting economy has permanently altered the data storage landscape. Storage managers are eager to pursue technologies that can help them make better use of their installed systems by ensuring that data resides on the appropriate gear, by using available capacity effectively and by removing data that’s no longer accessed.
By pooling available storage resources, storage virtualization can help achieve some of these efficiencies. But despite improvements in the technology and its implementation alternatives, adoption of storage virtualization has been relatively slow. Now, however, our survey reveals that 34% of respondents have virtualized at least some of their storage. That may be a relatively modest number that hasn’t budged an awful lot over the past year and a half, but if the 39% of survey takers who said they plan to acquire storage virtualization technology this year follow through on those plans, adoption rates should improve.
