Hi all
Last night I made a massive mistake and managed to delete the 2 vmdk's containing my Exchange Mailboxes and Logs.
Never fear, for I had done a full backup of the VMDK's earlier that day with VMWare Data Recovery.
At 2:30am it had completed 20%. Its now 13:45 the next day and its still on only. 75%
Monitoring the SAN using Resource Monitor, I can see Disk I/O is sitting at around 5-10MB/sec. Network Utilisation is around 100-120Mbps.
This was done on a bit of a budget as detailed below but it still should not be this slow in my opinion. Where is my bottleneck?
THe iSCSI SAN Disks are NL SATA disks. Yes I know, but still should not be this slow?
There are 5 1Gb links going into the SAN Switch (seperate network to Data), but only 1 of these are operational as I messed up the Link Teaming (chose wrong type).
Could it be this? Surely if this was maxing out, it'd be at 90%+ utilisation?
The disks are 4 NL SAS (SATA) disks in Raid 5 or 6 (cant rememebr which, and I cant access the concole right now).
Using DiskSpeed, the Max Read speed is clocked at 229.82MB/sec. Which is miles from 5-10MB/sec its operating at for this restore.
The Data network (which is the VM Management and Client Access network) is only 100Mbps (this will change to a GB Switch later this week), but I dont think the restore needs to even touch the data network?
Where is my bottleneck?
I'll see if I can knock up a quick diagram.
Where is the vDR repositiy stored?
and where is the target destination?
