On the contrary, we sell interface adapters that will hook SSA up quite nicely to HP9000, HP3000, SUN, DEC, NT, Netware, SCO, NCR, and a bunch more.

In an Oracle environment, we have had customers seen 200 - 300% better performance with SSA than EMC. It really depends on how it is all set up, and what your data looks like.

Furthermore, the 2MB of cache in each SSA drive is now available for use.
