Hello and thank you for reading.
Currently we have a cluster/ha/fencing of 5 identical Proxmox nodes running roughly 20 virtual machines. Each node is an IBM x3650 M4 with 512Mb Cache and BBU with Raid 1 SAS drives (just for OS), bit overkill. We store all of our Virtual Machines on a Synology iSCSI+LVM storage with each guest set to write-through and get roughly 37,000 iops on the guest.
The Synology white papers states that it supports white-back and I understand this would have nothing to do with the internal BBU and Cache but would it be safe for me to enable this on my guests? We have ran a few tests in write-back mode and get roughly 90,000 iops!
