I am new to oVirt, and I am trying to find the right solution for my LAN. On an air-gapped network, I have 3 Dell PowerEdge servers running Alma Linux 9 and 1 IBM SAN. I have 3 iSCSI connections from the IBM SAN to the 3 Dell servers. I am looking to install oVirt as 3 Enterprise Linux hosts on the 3 Dell servers. I need the 3 Enterprise Linux hosts to have shared storage, so all 3 hosts can access all of the virtual machines. I need the storage to have high availability, so if 1 host goes down the virtual machines can run on the other hosts. Which kind of storage do I use for this? NFS, iSCSI, cluster...etc? Also, do I connect the IBM SAN to only 1 host, and share that IBM SAN storage with the other 2 hosts, or would I create 3 separate iSCSI connections to each host? I would really appreciate any assistance from anyone. Thank you.
HI, Each host should have its own iSCSI connection to the SAN. That, most likely, implies an iSCSI connection between each host and the SAN. I suppose you could use NFS instead of iSCSI, but I suspect iSCSI would be better. You do NOT want to have host1 have a connection to the SAN and then hosts 2 and 3 access the SAN via host1, because if host1 goes down, then hosts 2 and 3 lose access to storage. Note that you still have a single point of failure: the SAN itself. -derek On Fri, October 31, 2025 9:44 am, provensen--- via Users wrote:
