Re: Cutover from 820 to i5/520

[Philipp Rusch <philipp.rusch@xxxxxxxxxxxx>]

But Kirk,
you did not move your "old" RAID controller, did you ?

Mike, I doubt that a 2748 will work in a 520, besides you have to have
another system frame (0595) for the number of disks you are moving.
The main system frame holds only up to 8 disks which are controlled by
the internal controller.

HTH,
Philipp
