    ESXi 3.5 U4 on HP DL380 G6 has slow disk performance

    Keith001 Novice

       

      I've installed ESXi 3.5 U4 with and without the latest VMware patches on an HP DL380 G6 server with a p410i RAID controller configured with 8 SAS drives in a RAID 50 configuration.  The server firmware (RAID controller and BIOS) have been updated to the most current versions.

       

       

      Unfortunately, a RHEL4 VM only achieves a maximum of 5-6 MB/s in disk IO for write operations.  When I run 2 different RHEL4 VM's simultaneously, the disk write performance is 2.5-3 MB/s each.

       

       

      I'm fairly certain the HW is good because I've performed a native installation of RHEL5U3 on the server and have used that OS to do a local file copy at 250+ MB/s.

       

       

      Does anyone have any knowledge of performance issues regarding the HP Smart Array p410i RAID controller and the VMware ESXi 3.5 U4 cciss driver?
