Next Ten Steps You Shouldn't Take to Make Storage Run Faster-6 Next

Automatic tiering software attempts to migrate data depending on its level of use, with “hot” data on the faster tiers. The issue with this tactic is that past behavior is not indicative of the future. Data that may not be used for weeks at a time (like month-end reporting tables) ends up sitting on slow-tiered storage when it is needed. Once used, it moves to faster-tiered storage, replacing the data that may be used on a daily basis. The result is that any irregular usage pattern can have a vast and detrimental ongoing effect on performance.

Typically, compromise can be a great thing – certainly a mandate in most relationships, but not in the world of IT, and especially not in the storage space. In IT, compromise always comes at a cost. For years, IT has been inventing and implementing workarounds to cope with the poor performance of storage systems bound by mechanical hard disks. As processor, memory and network speeds have repeatedly doubled over the years, storage media have failed to keep pace, creating unbalanced ecosystems.

Often, these compromises are so ingrained that they have become second nature. No thought is given to the overhead because no alternatives existed. That is, until now, with the proliferation of flash-based storage systems and the trajectory of the all-silicon data center.

Fahima Zahir, product marketing, Violin Memory, has identified the top 10 coping mechanisms found in today’s storage environments that should be avoided.
