Perfect RAID 0 stripe size for Adaptec 5805Z & 8 Intel X25-M SSD.....

[symm]

depends on your application

what are you going to be storing ?

VMs, VMs & more VMs.....for Hyper-V R2 via iSCSI SAN set up.

I did some testing on Windows2K8R2x64, seems like bigger stripe size is not showing good performance. But I'm not sure about the characteristics of linux based application like Open-E.

Now I'm also wondering.....do we need to create the right partition size and align it based on the stripe size to see the best results?

Here is a article that explaines the stripe size better,

I hope it helps

Not particularly useful in this case but thanks!

My concern here is, does open-e use a particular block size for data transfer or it can be controlled by user.

When working with RAID controller like Adaptec, does it matter what we could configure at the open-e level? Or it leave it all to the controller?

Last but not least, what is the impact to all when Intel SSD is used? Some engineers claimed that 256KB is optimized but I found out smaller size seems to perform better. That was my testing on Windows2008R2, not sure about Open-e and Linux as I do not have so much time to test all combi so far.

Would see if I could post my results and findings earlier than any sharing here

by the way, I am using 8pcs x25-m with 5805Z.
