Hi all, We're working on upgrading our storage solution to a proper network attached storage. Before this, we had an NFS share on some mounted disks on the management server. Our new setup is a NAS running TrueNAS (zfs) with 64 GB ram and 8x8TB, 7200 rpm hard disks mounted to cloudstack over NFS.
It seems the performance is however much lower than before, resulting in somewhat unusable virtual machines. In VMs, IOPS can be as low as <10 IOPS, vs 100 with the management server setup. Is there a recommended setup for primary storage to yield better performance? All the best Pierre, kthcloud
