I have a Windows 2008 R2 server with:
- 1 x 80GB SCSI, partitioned:
- 100MB reserved
- 79GB NTFS windows
- 2 x 1TB SCSI HDD running in a hardware RAID 0 striped configuration, partitioned:
- 7GB RAW (left for guest swap)
- 877GB RAW (left for guest root)
- 976GB NTFS (used for other VM)
I'm trying to use the 2 RAW partitions for the Linux VM as I've seen that the default emulated virtual HDD seem to hurt I/O performance. I've configured the HDD in Vmware 8 for the VM but the ubuntu 12.10 server install shows the HDD as having the real full size (2TB), not the partition(877GB).
I've read on the internet that SCSI can cause issues with VMware RAW HDD, but I don't know how up to date that information is for VMware 8. If so would VirtualBox's RAW HDD work in this case?
Are there any methods I could use to improve HW I/O, as I want to use a Mysql database in the VM that would require lots of writes and reads.
