True. But distinct separate RAID volumes with their own hot spares would be nice.
You say you ask for the world, but rumour has it you may get what you ask for in 1998. Some of the rumblings I hear coming out for the high-end Netapps sound *very* sexy, and should address almost all high-availability and failover circumstances.
We're living in the age of Wide Ultra SCSI. Maybe a NetApp engineer can comment on whether this would, or would not, make much of a real world performance. I was under the impression that you'd get more TPS...
Wouldn't much of that advantage be masked by the caches?
Straight mirrors....straight concatenating and striping...
Mirroring within a RAID set and cross-chassis mirroring have been two items near the top of our wish list, having migrated from Ultra servers with SparcStorage Arrays. On paper, two Ultras cross- connected via fiber-channel to two SSA's configured to mirror disk sets across two chassis (chasses?) offer much better survivability than a single Netapp. Now if only Netapp could take that idea and implement it in a bulletproof, no-brainer fashion...
