- My  storage server  has upto 8 cores  running linux kernel 2.6.32.27.
- I created  a raid5 device of  10  SSDs .

No it is not normal practice.  I 'preach' against it regularly when I
see OPs doing it.  It's quite insane.

There are a couple of sane things you can do today to address your problem:

Hi Stan,
Follow-up question for  2  types of setups i may have to prepare:
1) setup A   has   80   SSDs.    

This is simply silly.  There's no need for exaggeration here.

 2) Setup B  has only 12 SSDs.  Question:  Is it more practical to
have only one raid5  device,  even though I may have 4-5  physically
different  clients or create 2 raid5 devices each having  6 SSDs.

As I repeat in every such case:  What is your workload?  Creating a
storage specification is driven by the requirements of the workload.
