I have heard that a vlan might help, but without a swich or anything, and I doubt it could really be a 10 tims improvement. . The best solution I found was just to go back to three-tier, go with FC or iSCSI, and go that route. Referring to your brand statements, if a user's budget doesn't get them into the Cisco type area, your backplane will rarely manage wirespeed on all ports. I will only write about this in short here, only to quickly show the process and to test availability. You can also use the target that ships with Storage Server 2012.

If not, if go with one client one storage, if the target crashes the client will (probably) crash or at least it won't be able to access the storage. Compared to any shared storage solution we costed the price/ performance ratio of S2D was way ahead of everything else. In S2D, you can build highly available storage using local storage. Can I: Connect the iSCSI target directly to our ESXi host and add it as a datastore. The end result is usually that an application utilising the network hard starts to impact iSCSI performance. the old block storage is what i want to move away from, im not lookng at connecting that up to myS2D setup. I'm building own SAN on Debian 11. Together with the embedded architecture, S2D promises some performance improvements over other HCIs.
