How to change vCenter Operations Manager session timeout
I’ve been using vCenter Operations Manager for a while now at work for all the great information that can be found about our environment so I tend to log into vCOp at the start of the morning and then come back to as I may or may not need it thoughout the day. One thing that has kind of annoyed me is having to constantly log into the standard UI multiple times a day due to the default 30 minute timeout value.
Luckily, with a bit of SSH and a few commands we can increase this timeout to anything we like or even disable it all together!

Shrink a thin provisioned VMDK disk
When maintaining a Horizon View environment I like to keep my parent images as small as possible and over time a thin provision disk can start to grow on you if you don’t watch it – be it from downloading installers, updates, or even running disk defrag. While there isn’t a simple, one click button in the View Administrator Console there is a fairly easy manual method using vmfkstools.
Before we can use “vmkfstools” to shrink the VMDK file we must zero out any unused space on the thin provisioned disk. A simple way of doing this is by using a free utility called SDelete from Sysinternals.

Increase incremental backup speed by enabling CBT
In a recent VMware environment I was working in, we noticed that our incremental backups was taking a long time (like up to 7-8 hours) to complete. After digging around it was found that VMware actually has a feature built-in since version 4 called Change Block Tracking (CBT). CBT will track any blocks that were changed since the last backup and tag them and stores the information in a -CTK file. The obvious benefit is that now the third party software only backs up the changed block and not the entire VM each time, reducing the amount of data being backed thus speeding up backups and even lowers the CPU utilization on the VM host.
CBT is disabled by default though there are some backup tools that will enable it automatically or you can enable it manually which can easily be done following these steps:
