I have a fully-populated Supermicro SSG-6037B, which is a 3U, 16-Bay chassis with two Server blades in the back. Each blade is a dual Xeon with 64GB Ram, booting from a pair of SATA DOM modules internally. Both blades can see the SAS disk array at the front as JBOD, and there is direct PCIe communication between each blade internally for heartbeating purposes.
Each blade has 4x1G and 2x10G ethernet interfaces.
It’s basically a Tegile T3100 which we retired once Tegile were bought by Western Digital and dropped support.
Can I use TrueNas to provide a similar kind of storage platform? I’d like both blades to run TrueNas as an Active/Active cluster, so I can provide seamless connections to the disk array inside, by either iSCSI or NFS.
As far as i know, it’s not supported for two devices to access the storage disks at the same time. The setup sounds similar on how truenas does high availability, with an active and a passive node. But HA is an enterprise feature and only available on hardware purchased from truenas…
Can never be Active/Active as a ZFS pool cannot be accessed by two nodes at the same time. Active/Passive is as good as it gets with ZFS and on failure Passive Node imports the pool. Well thats the idea but if it goes wrong bye bye pool (split brain).
You can have two TrueNAS systems replicating data from A to B quite regularly and then put a global namespace above it and that would give you something similar but second target would only offer read-only by default in the event the primary went away but thats using SMB.
I should also mention that TrueNAS Enterprise does support Active/Passive controllers and manages failover automatically for you using their secret sauce
