![]() I had 2 servers with P400i controllers that had no problems and 2 servers with P400 controllers that had the serious problem. And my VM's were very fast in their copy jobs of large files. But when I copied to /root from one machine to another, it was blazing fast. Then I thought it was the Service Console specifically, because migrating VM's was taking hours and hours and with VEEAM FastSCP, I could actually see the transfer rate when copying files from /vmfs/volumes/storage. I fortunately had the P800's to work with.Īt first I thought the issue was with the network because the customers were VLAN'ing from one server room to another. Other people have posted they had success with a Battery-Backed Write-Cache Module (BBWC) from HP, but I didn't get the chance to try that. So, I pulled the P400 out of the system and connected the drive array to the P800 controller. My customer happened to also purchase the Smart Array P800 controller (supported by 3.0.2 and an auxilliary driver CD for 3.0.1). ![]() Turns out it was the Smart Array controller. When I copied to file systems other than VMFS, it was fast. The VMFS was extremely slow (1000Kbps transfer rate on a Gigabit Ethernet connection, for example). I just had an issue with an HP D元80 G5 local storage Smart Array P400 (not P400i) SCSI controller: ESX versions 3.0.1, 3.0.2, 3.0.2 Update 1.
