We have questions with respect to using these controllers
in ESA10000/ESA12000

1) We've gotten conflicting info about this.

Can we create a RAID 5 array then "partition" the array
and present it to several different machines as different
disks? That is, could we make such a RAID 5 array from 3x9GB
drives, then give several machines a piece of that to store
OS files?

2) Re: switched fibre channel using the HSG80 and redundancy

If we have two Hubs, can we cross connect them so that each controller
is attached to each Hub?

In two-hub/two-controller scenario could we attach half of our
servers to one hub and half to the other, and in the event of a
hub failure simply replug the server cables from the failed hub into the good
hub?
