poweredge T310 -
i had 1 TB hard drive earlier. performace was OK. added a second drive, 1 TB hard drive, SATA, compatible wth poweredge t310. Noticed performace very very slow. sar report shows, i/o wait at very close to 100% and idle is 0%. i am using it for Linix Virtual machines. I notice whatever application running from the first hard drive is OK. When I use the Linux Virtual Box created on the second hard drive, i see extremely slow performance as mentioned earlier. Any suggestion to trobleshoot/fix this issue will be greatly appreciated.
