Energy efficient, high performance storage is not necessarily an oxymoron.

Green is undoubtedly a pertinent issue in today’s business environment. However, business decisions are always based on priority. Although the impending energy crisis is compelling, next to performance and capacity requirements, green status is a nice to have, not a must have. Companies cannot afford to compromise fundamental performance competencies in the name of going green.

However, the common perception is that energy efficiency and high performance are incompatible objectives. That is true with traditional storage architectures but there is an innovative storage option that blends the attributes of high performance storage with energy efficiency.

Atrato Inc recently started shipping their Velocity1000 (V1000), a 3U storage module with a unique packaging philosophy that accommodates 160, 2½” drives, creating a spindle density that delivers 16,000 IOPS in a single array. With 5,333 IOPS/RU and bandwidth approaching 2GB/s Atrato’s V1000 remains unmatched. This performance is delivered with an energy requirement of 50% to 80% less than other comparable solutions. A recent press release from Atrato describes how one of their customers, The Department of Energy, has implemented the V1000 to realize new green objectives in the data center and to eliminate the storage I/O bottlenecks they were experiencing as they implemented their VMware and began growing their virtual desktop infrastructure.

Metrics to measure and monitor performance are well known, however, the practical understanding of these metrics is often foggy. There are two important aspects to consider. First, it is imperative to understand how green will impact the bottom line, and how it will bring value to the data center. Second, it is important to have a working understanding of how to measure green for data storage solutions. These two goals will help IT professionals make intelligent decisions on how to best use green to increase productivity, save money, and reduce management complexity.
