Hi

I'm new in HDS and we want to connect some IBM Aix P590servers on our new HDS Box for that  i have 2 questions:

1) I have seen in this Forum that 'AIX 5.3 + VIO + HACMP 5.3 aren't supported yet'
The message was:
I've check HiFire and indeed AIX 5.3 + VIO + HACMP 5.3 aren't supported yet.
Is that correct ? What's HiFire ?
Could you send me to some link where i can find what's is supported and what is not ?

2) What's would be the best for performance:

a) Creating Small Ldevs and stripe them at The OS-Level using Volume manager
b) Create Luse using different Small Ldev which use concatenation
c) Create A Big VLL

The Fact i write To cache, instead of disks, is it making any differences if i stripe or not my volume ?

How Front-End process write Data to Cache, and how Back-end Director Destage it to disks

Thanks a lot
