Our ESXi hosts have always been slow booting when it came to iscsi_vmk loaded successfully - sitting here for almost 5 minutes.

In all a full server reboot takes almost 12 minutes.

We have 9 iSCSI targets per host (5 SANs with redundant interfaces) configured as dynamic discovery targets.

Has anyone experienced this? Can it be remedied with static discovery mode? Are there any debug steps we can work through to help diagnose this?

(All our targets are accessible at boot so i'm assuming the host isn't stuck retrying to connect to a target)

VMWare ESXi, change the default path for a VM

as seen on Server Fault - Search for 'Server Fault'
For some reason VMWare ESXi has decided that one of my VMs is on a completely different path to the path it is actually on. So my VM is on /vmfs/volumes/long-guid-here/my-vm-name but when I try to open it I get the message "File < unspecified filename was not found." Which is not really surprising… >>> More

I need to get VMWare Server running inside of a VMWare ESXi virtual machine

as seen on Server Fault - Search for 'Server Fault'
Yes, I know running a virtual machine inside of a virtual machine is a bad idea. Yes, I know it will be very slow. However, our production system required VMs in VMWare server and I do not want to setup a real server for each of our developers for testing. I would like to be able to setup all of… >>> More
Eject disk on Mac Pro running VMWare ESXi

as seen on Server Fault - Search for 'Server Fault'
I'm almost embarrassed to ask this, but I'm stuck. I installed VMWare ESXi on a Mac Pro. It's working great! The problem is that you press F12 to eject the disk, and F12 is what you use to shutdown ESX. I can power down, open the case, pull out the CD drive and use a paper clip to force the drawer… >>> More

Do I need VMWare vSphere?

I'm planning use vmware to upgrade some of very aged server instead replace with all new bunch of server. VMWare vSphere sounds great but because of low budget I can't afford for both licenses and SANs. Without SAN, is vSphere worth the price?
