Cisco ISE CPU/Memory Upgrade

[Rafael Mendes]

Hello Everyone,

I have a Cisco ISE in Vmware environment and i need upgrade the cpu/memory in my Policy Service Node.

How i can perform this? Its only increase the memory/cpu in vmware machine environment?

Tks.

Rafael,

Since this is a vm environment I would setup a window and provision a completely new virtual machine with the settings from the PSN that doesnt have the resources allocated.

Remember to backup your certificates and private key and deregister the old node prior to making the switch.

Thanks,

Hi Tarik,

So, in vm environment, if i created a machine with 4GB Memory and 4Cores CPU (for example) i cannot change(upgrade or downgrade) it after the ISE installed?

I need create a new  virtual machine resource with new cpu and memory parameters(8GB and 8CPU for example) and reinstall the ISE?

Rafael,

That would be what I would strongly recommend since it is not documented on what the best practices are from Cisco and with ISE database being sensitve to how the hard disk are presented, I would strong suggest starting fresh in order to rule out any stablity related issues (if you face them) in the future.

Thanks,
