Before Host Profiles there was vicfg-cfgbackup.pl

This last weekend I was reminded of a RCLI command that creates a backup of your ESXi Host configuration.  A client had an ESXi host where the USB drive failed.  The system didn’t entirely crash, it pinged so HA didn’t kick-in however hostd and vpxa weren’t responding so management from vCenter was impossible. Performing a reboot of the host proved it was a USB failure when it failed to boot. So, HA kicked in finally when the host was powered off - however the remaining hosts in their cluster did not have adequate... [Lire la suite]

Active / Standby etherchannels?

I’ve seen this a couple of times already and just had a very long phone call with a customer who created the following set up: So basically the first two nics are active with load balancing set to IP-Hash and configured as an Etherchannel on the stacked Cisco 3750’s. The second pair are “standby”. Also with load balancing set to IP-Hash and configured as a second Etherchannel on the stacked Cisco 3750’s. A diagram probably makes more sense: Explanation: All NICs belong to the same vSwitch. Etherchannel 01 consist of “vmnic0″... [Lire la suite]

Best Practices: running vCenter virtual (vSphere)

Yesterday we had a discussion on running vCenter virtual on one of the internal mailinglists. One of the gaps identified was the lack of a best practices document. Although there are multiple for VI3 and there are some KB articles these do need seem to be easy to find or complete. This is one of the reasons I wrote this article. Keep in mind that these are my recommendations and they do not necessarily align with VMware’s recommendations or requirements. Sizing Sizing is one of the most difficult parts in my opinion. As of... [Lire la suite]

New feature in VMware Workstation 7 – Auto Protect

AutoProtect – Very convenient way to work and have your VM been snapshotted automatically in the upcoming release of VMware Workstation.
