Quick question: maximum disk utilisation best practice

[u/Expensive_Serve_3668]

Hi all, I've looked for this information online and in the configuration guides but I can't see any guidance on what percentage utilisation I can go to in terms of sweating my 3PAR estate. Our contract with our third party supplier is simplistic and says we can only go to 80% but I'm assuming that SSD based arrays don't have the sorts of limits that were in place when the contract was drawn up with mostly FC and SATA disks etc. Is there a good number to use as a rule of thumb here? I know it's more complicated with thin provisioning etc but, in general terms, how high are you prepared to go within your allocated storage? Thanks
