vmware esxi server 2003 high pages/sec and disk queue
Host: esxi 4.1
host disk: raid5 sata (yeah, i know...budget constraint)
Guest: Server 2003 32-bit std edition
ram: 4gb
Performance monitor show intermittent (but frequent) high memory pages/sec and high disk queue length. This results in issues with SQL server it is hosting. Clients running an app that connects to the database get connection errors.
The guest was a P2V conversion initially P2V'd to a vmware server 2.x guest, then converted again to esxi.
I noticed the v-disks are IDE:0, 1. Do they need to be converted to scsi?

The ghost method was giving me 80MB/min transfer rate. At that rate, it would have taken over 10 hours to clone the drive.
Would I be better off running the vmware converter or something like that? How about vmfstools? Is there a command line conversion - short of editing the IDE vmdk file and adding a bunch of numbers which seems to be an invitation for trouble.

The ghost took 13 hours for 100GB. Painfully slow, but successful. I'll know over the next few days if that was the problem, but given that it took 13 hours at 75MB/min, I believe it is.
