I dont know if anyone can help on here, We are having issues backing up to some LTO 4 drives on our SAN, the san switches are old brocades running at 2 Gig, the devices are backed up via a HP G5 server running netvault, the servers sit on the LAN and are mainly teamed to 2 GIG using the HP software. We had a consultant come in last week and say the speed is ridiculously slow, someservers are backing up at no more than 10Meg per second data rate, he said he normally see's around 100meg when backing up using LTO 4 drives,
he used a utility called fstfill which created a 1 gig file then wrote to disk, he said the disk performance on the old servers was terrible, some at 8Meg a second, could this be the reason??
Can anyone shed any light on why they would go slow slow??
hope somone can help
