ISE 2.1 VM Resouce subscription

Hi All,

The install guide highly recommends dedicated VM resources and not to share or oversubscribe resources,

Is this enforced through the OVA or via any other means?

If ISE is run in an oversubscribed manner do we require the customer to vacate other guest on the Esx host if facing issues while trouble shooting through TAC?

Many thanks

Alistair

Re: ISE 2.1 VM Resouce subscription

VMware resource sharing is NOT supported. VMware resource sharing is one of the best ways to guarantee mysterious and intermittent problems with ISE nodes. VMware configuration should be one of the first things a TAC Engineer checks for with certain symptoms because it is so insidious.


The ISE OVAs are explicitly named for their equivalent appliance model and hardware requirements:

     ISE-2.1.0.474-virtual-SNS3415.ova

     ISE-2.1.0.474-virtual-SNS3495.ova


While the ISE OVAs do enforce the hardware requirements for CPU, RAM and Disk, they have no way of knowing if the resourcing is dedicated or shared within VMware.
