Hi All,

Ive been playing with scaleio for a couple of weeks now with Xenserver as a hypervisor still trying to get better performance out of it. We have 3 nodes.

Im wondering:

We are still on a 1 gig network as our read sequential is hitting 1 gig however the writes are no where near to the reads. If I can increase the performance to at least a gig Ill get hold of some 10gig pci cards.

1) Does the entire pool only operate as fast as the slowest drive in the entire cluster ?

2) Would 1 slower network card effect performance of the entire cluster or would that server just serve less data ?

3) Would 1 slow hard disk in the cluster effect everyones performance or would the faster drives just process more operations than the slower ones.

4) Could it effect the cluster negatively by adding in a slow PC "server" with multiple drives to try increase iops.

Thanks so much.
