Hi,
I've got a Dell Poweredge server with Esxi 4.1 installed and 3 virtual machines running Windows Server 2008 R2. One of the VMs which is running Exchange 2010 and is running out of disk space. I have consequently added additional hard disks with RAID1 giving me another 930Gb. The existing Datastore is 900Gb made up of 3 hard disks on RAID5. My question is, should I extend the existing datastore's capacity with the new drives or is it best to create a new 930Gb datastore to create the new virtual disks for the Exchange Server? Also, if I create a new Datastore, should it be with a 1Mb or 2Mb Block Size?
Any help and advice would be greatly appreciated.
Thanks in advance.
Mike
