Best Practice to add SSDs for flash cache ?

[Marc0]

Hi

We just bought 4 SSDs to implement Flash Cache for our 7400.
Now, the 3PAR has 6+1 Cages but where do i place the SSDs ?
All 4 in 1 Cage, all in the Controller Cage or a any other ?
Or is it better to distribute the SSDs over 4 Cages ?
Does this even matter ?

Any advice would be much appreciated.

Hi

you must always install drives in pairs

so I would put them in the controller node cage

if you have four controllers

remember you can configure 768GB per controller pair

and  it is in raid 1
