vSphere 6: Modify DCUI Idle Timeout

In ESXi 6.0, VMware introduced the DCUI idle  timeout. You can modify DCUI idle timeout via the Direct User Console Interface. You can specify the number of idle minutes that can elapse before you must log in again in DCUI.

Set the DCUI idle timeout to zero to disable it. The maximum value for the idle timeout is 1440 ~ 23.3hrs.

Speed Up Your Horizon View Operations

How to speed up your Horizon View operations, you might ask? Well, you don’t have to buy an all-flash storage system or beef up your ESX hosts.

VMware Horizon View Administrator has some settings on max concurrent operations with vCenter and VMware View Composer. Increasing some of those settings can decrease the time of those operations, however when decreasing those settings, you can limit the amount of IOPs pushed to your underlying storage system, too.

Limit IOPs Per VMDK

One of the many features in VMware vSphere, which I didn’t know, is the capability, to limit IOPs per VMDK without setting any limitations on the underlying storage system or for the whole Virtual Machine.

LimitIOPerVM

As you can see on the image above, it is easy to limit the IOPs per VMDK within the vSphere web-client.
Just browse to your Virtual Machine and go to edit settings. Select the “Hard drive”, which you would limit on IOPs and expand it.

Note: By default, all VMDKs are set to unlimited IOPs.
