The Ramsan has its own on board cpu (other similar devices such as FusionIO don't have this)so there is no impact on the server performance.
  • The config was a hypothetical one based on my own experience, so I can't comment on performance. I can say that based on my experience with SSDs that the proposed config would be able to meet whatever external access load you could place on it with Open-e.

  • The Ramsan values are based on a artificial/benchmarking load levels that would not be experienced in any real world environment you could construct.

  • All RAID controllers have their own CPUs, which offload all IO from the server. Only software based RAID solutions use the server CPU. In this respect the Ramsan solution doesn't provide anything special.
