The current proposal is to replace all of the Samsung SSDs, while simultaneously expanding the RESTBase cluster to 9.6T/host. T205092 proposes to piggy-back this on the already planned (routine) replacement of restbase200[1-6]. Arrangements for the remaining 18 hosts still need to be made.
What we need specifically likely depends upon whether it makes more sense to replace the entire host (for example if a lease or warranty is about to expire).
When replacing the host does not make sense, the final outcome depends upon whether the machine is equipped with Samsung SSDs. Those //with// Samsung SSDs should have them replaced with 5 1.92T devices. Those //without// (those with Intel or HP SSDs), can have >= 3.2T of SSDs provisioned.
(NOTE) Someone with access to information on the status of these 18 machines (lease v purchase, and the remaining time before routine replacement), will need to help out from here.
