Craig - Store-Age is an appliance company. However, to be practical, they must attach to a RAID subsystem. I could write for hours on all the issues and problems that many companies have doing this.

I gave just a few of them in my previous posting, here are some more
- Requalifying solution when RAID vendor changes firmware. (This
- Significant work must be done to qualify enclosures for channel failover. Techniques vary considerably across product models, and sometimes change with firmware
- When/if an enclosure goes into degraded mode, presumably because of a drive or (RAID) controller problem, then additional work may be required to insure painless migration
- Load balancing? For best performance, some RAID engines work best if it is off, others work best if it is on, sometimes it is dependant on the LUN configuration.
- Optimization. All RAID engines have dozens of configurable parameters for everything from block size, flushing algorithms, stripe size, and even just LUN size because they all have their own virtualization. What is best? Is Store-Age going to figure out best balance for all makes and models? No way. Heck, the RAID vendors have enough problems doing that just for their own hardware.
