As shown in the attached log, I am experiencing constant datastore disconnection issues. This is an IBM/Lenovo RD120 rack server with an adaptec 8K controller. I have 3 disk arrays on the server: a RAID1 array that the sbs2003 resides on, a 3 disk RAID5 array that hosts some XP vm's, and a single disk that the server backs up to. This does not seem to be an IO issue as problem occurs with very little load on the system. The logs attached were taken then the system was completely quiet except for the server running the backup. So far, I have updated the motheboard and RAID controller bios without any results. Can anyone shed any light on this issue for me? Thanks!
