I bought a PowerEdge T110 II server in 2011. It has 2x4GB RAM, and 2 1TB SATA drives in RAID 1 via a PERC H200 controller. It's running fine, but I think that I should replace the hard drives, given their age. I'd also like to add more RAM. I'm running ESXi 5.0; after the proposed RAM/HDD upgrades I'd like to upgrade to ESXi 6.7 which I think is the current version. I'm thinking of upgrading to a pair of 2TB SAS drives.
By searching this forum, I've learned that SAS 3.0 drives won't work in a T110 II; so I'll apparently have to go with SAS 2.0 drives instead. My first (2-part) question is "which 2TB SAS 2.0 drives are compatible with a T110 II and where can I buy them?"
I'm having trouble finding RAM. I need 1333MHz dual ranked UDIMMs (2x4GB) but the places I've checked don't seem to stock it any more. So my second question is "where can I buy RAM for a T110 II?"
Finally, I've briefly outlined my proposed migration to ESXi 6.7 below. Have I got this right, or are there gotchas I need to be aware of? Maybe someone can point me to a detailed outline.
back up all VMs
shutdown/power off VMs
shutdown/power off T110 II
insert new RAM & replace HDDs (with appropriate BIOS changes, if necessary)
