Using tape libraries under ESX 4.1 – Take 2

Posted on

After ruling out SCSI pass-through and iSCSI, I found a link referencing PCI pass-through on ESX servers. This requires a system that supports Intel VT-d and essentially ties a PCI card to a running virtual machine. The VMware feature is called VMDirectPath I/O, and information on configuring it can be found at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1010789 Once I […]

This process worked fine, but left his VM disks using almost their full capacity, even after the files were deleted. When attempting to SVMotion the VM (and re-thin the disks), it failed because there wasnt enough room […]

Recovering from BSOD with crash dump

Posted on

My system just crashed and performed the traditional Blue Screen of Death (BSOD). The bad news is that I had open files that I have now lost. The good news is that it created a dump file to review and see what caused it. 90% of all crashes are due to a driver of some […]
