The transition to various flash-based storage is essentially complete for anything that is inside the actual server (with booting the thing off SD card and that being the only storage inside being somewhat common), but for SAN systems SSDs aren't that much interesting, because the bottleneck is not in the storage media itself, but in the interconnect technology (typical SAN storage shelf can saturate it's FC ports on random IO traffic regardless of whether it is based on flash or spinning rust at 15k RPM)
