So, as my sig indicates, I have a full Norco 4220 case with both my production and backup pools housed in hot swap bays. I still have a lot of space left but I was wondering what this group's opinion would be on the best upgrade path if I want to add more drives (might not happen for a while if I instead up-size the drives one at a time).
My plan would be to connect an external SAS enclosure to the system as I have extra SAS ports available. Looking at pre-built SAS expanders with multi-bay (more than 10) hot swap capabilities seems to be pricey, running in the order of ~$2000USD for the chassis (new).
Alternatively, what are your thoughts on just using another 4220 case (20 drives is perfect for the expander that I am using, 24 would also work if I used both of my free SAS channels), PS and SAS expander? My only stumbling block with this is the power supply turn on issue, unless there is a cheap dummy board that you can install that can control the power supply. I would ensure that all pool drives were in the same chassis JIC the external cabinet does not power up with the server. Worst case would be missing pools.
What other options are out there for upgrade paths?
Thank you for your thoughts.
Cheers,
