Re: SSDs - RAID or Mirror ?

Hi Larry

that's what I have done in the past and that is my preference. Is there an
IBM best practise recommendation I can refer to or do that you know of or
do you have some logic as to why (like, because they are SSD's)

I'm guessing you have something due to the quick answer.. :)

Hi all

I have a customer who has a ordered a system with 4 x 387Gb SSDs in the
CEC
and 24 x 283Gb disks housed in a 5887.

With respect to the SSDs, what is the better approach - Mirroring or RAID
? The system is not pushed for space so mirroring is an option if there is
a reason for doing that, otherwise either approach works fine for this
install.

I normally prefer to hot spare RAID sets these days and I guess I could do
a 3 disk RAID set and hot spare it (not my preference...) but in that case
it seems to me MIrroring would probably be a better approach.

Any opinions as to which approach is better ?
