Good day everyone.
We have one Dell Powervault MD3220i with 18x 900GB 10K Rpm drives that currently running out of space. We are going to attach to it an MD1220 with a 6Gb SAS Cable and having 18x 600GB 15K rpm drives and 4x800GB SSD.
We pretend to move to the SSD volume some of the most I/O intensive servers at least one app server and one exchange server and to use this SSD volumen for VMs snapshot so it can improve the time it takes backup software to create/remove the snapshot wich currently limit us to not run backups/replicas on production hours so our RPO is about 24 hours and we are looking to low that.
Please let me know your thoughts/recommendation on this or better ways to improve it.
Thanks in advance
