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

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

    How many different combinations of RAID options do you need to consider when designing a storage solution? RAID level 0,1,4,5,6 or 10? What about the drive type? Do you need SAS, SATA, Fibre-Channel or SSD? What would be the best stripe size for this system? In a database environment, would you use the same design for all file-types, or would you need to design separate solutions for the data files, the transaction logs, the temporary files and the backups? How much time needs to be spent looking for the best solution? Let’s stop there. That should sufficiently illustrate the point: RAID is complex.

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.
