Re: 5727 and 5776 (520+ disk options)

As far as I know, the only supported support for the base 4 drives in a 
520 is the embedded controller. To use the 90mb cache controller in the 
520 CEC (cpu) also requires the FC6594, vs the 6574 for the imbedded 
controller.  Take a hard look at your actual disk performance numbers and 
disk space requirements. Adding the PCI-X controller will require a 2nd 
raid set. 

Also earlier you mentioned getting an Express Box. Are you planning to get 
a 2nd tape drive? last I checked All Express systems came with a 30/60gb 
QIC unit. If you can migrate your current SW to the new system, a Value 
Edition with either the internal LT02 or the 8mm may be more cost 
effective.

5727 and 5776 (520+ disk options)








Ok... Who's familiar with the 520+, 5727 (embedded 40mb cache RAID
controller), and 5776 (90mb cache PCI-X RAID controller)?

It looks like I can put a 5776 in our new 520+'s CEC, but i'm trying to
figure out for sure if I can drive all 8 drives in the CEC with it.  One
item i'm reading makes me think I have to drive the 4 drives in the base
slot with the embedded 5727 controller.  Does anyone know this for sure?

If I can drive them all with the 5776, would it be better to drive them 
all
with the 90mb controller, or split them with each controller driving 4
drives?    "It depends", right?  ;)
