Looking for advice on the concept of running Cold and Hot Storage on a single Unraid box.
I currently have a Dell XC630 (R630 for HCI) head sever running Unraid, connected to a 60 bay Dell MD3060e with about 24 HDD’s installed. I’m currently running Unraid with no array, but solely running 3 zpools (2 zpools on HDD on the 60 bay JBOD and 1 NVME Zpool).
The energy cost and heat output of the MD3060e is not longer acceptable, so I’m looking to deploy 2 NetApp NAJ-1502 12 bay SAS3 units and would like to migrate the 2 HDD zpools from the Dell MD3060e to the NetApp units and run those as the primary (HOT) Storage JBODS and run the MD3060e as a auxiliary (Cold) JBOD for say on-site replica’s once a month or so.
My question is in regards to running Unraid with the Cold Storage unit with minimal downtime. My theory is the Hot Storage 24x7 operation with the Cold Storage powered on at time of sync. Can I within Unraid stop the “array” and poweroff the Cold Storage unit, then power up the “Array” and run solely the Hot Storage or would I have to power off the entire set?
Hope this makes to anyone. Thanks in advance.
