I do not see why not, I have certainly had a system where the GUI was originally running on a storage node, then later a dedicated server was bought and spun up, and the GUI role moved over to it without an outage Daniel Daniel Kidger HPC Storage Solutions Architect, EMEA daniel.kid...@hpe.com +44 (0)7818 522266 hpe.com -----Original Message----- From: gpfsug-discuss <gpfsug-discuss-boun...@gpfsug.org> On Behalf Of Jonathan Buzzard Sent: Monday, January 8, 2024 5:32 PM To: gpfsug-discuss@gpfsug.org Subject: Re: [gpfsug-discuss] GUI server hardware requirements On 08/01/2024 09:37, ANDREW BEATTIE wrote: > Would be plenty for the gui role as it stands today, The ESS EMS > server does not use SSD at all, and it runs the GUI for an ESS > cluster. > I care not about the GUI role, only the RestAPI support.

Say just spin up a couple more and then retire the old ones. Or replace them one at a time? As it stands the machines are pretty old anyway and are spare because firstly the CPU is not supported in ESXi 7+, and then SAS adaptor is not supported in RHEL8+. Hence they are spare. However they work just fine under Ubuntu LTS 22.04 and we are likely to move away from RHEL after RedHat's stunt last year. However I would want to be able to replace them without downtime if required and as funds allow. JAB. -- Jonathan A.
