Help for SuperStorage 2028R-DE2CR24L?

[ITMAN]

Hi All,
In SuperStorage 2028R-DE2CR24L manual :
"
The system features eight lanes of PCI-E 3.0 connecting the left server module with the right server module.
This connection is used for high speed data transfers between nodes for High Availability server fail-over.
"
can you help me for how to use from it for HA between two node ?
systems on nodes are linux,

Thanks in Advance,

Didnt even know those existed, but a quick google brings up these.

Quoting @gea from https://forums.servethehome.com/index.php?threads/zfs-vcluster-in-a-box.22460/post-210162

These are the classic hardware solutions for "Cluster in a Box". SM combines two mainboards with shared disk access ex over redundant multipath SAS for both nodes in a single case.

That means you 'see' the drives of the other node (with 8 lanes max bandwith).
For your HA solution I would think that you can implement whatever solution you want to move the active cluster resources between the two nodes.

Its a similar solution (and likely requires similar implementation) as having an external jbod connected to two nodes via external SAS controllers.

Again Thanks,
I want see FC HBA from each two node, is it possible?
if yes, how to?

I dont think that will work, the Bridge is not sharing PCIe resources

Thanks Rand__,
