Hi,  In terms of whitepapers, the one that comments the most on this question would be the Host Configuration Guide located here:[URL]  Specifically your situation is called out here: [IMAGE]  I think the minimal approach from the guides would be break your hosts up per x-brick as depicted above given you have a dual-HBA host and probably reduce your zoning some unless you want more than 4 paths per host. This approach would require you to have some understanding of balancing the server load across the bricks as you added new servers.  If you wanted to go to the max of 8 paths per host given dual-hba's and not really have to worry about any loads across the bricks, you would maintain the zoning you have above as depicted here: [IMAGE]  In terms of the actual zoning, you can do either single-init/single-tgt or put all of the XtremIO tgts into one zone with a single initiator if you are constrained on zone counts in your fabric. The main goal is that an HBA should have at least one path to each storage controller on a given X-Brick for availability.  HTH
Today we had our XtremIO Two Brick Storage Array Configured. I'm looking for some guidance on Zoning Best Practices to our FC Switches. With the Two Bricks we have a total of Eight Fiber Channel connections, Four Fiber Connections to Fabric A and Four Fiber Connections to Fabric B. Below are examples of the FC initiators "Aliases" from XtremIO connections Fabric A & B.  How would I implement zoning for a new server that has two HBA's "One HBA per fabric"  For Example: Server Name: UCS01 - (HBA1 "UCS01_HBA1" & "UCS01_HBA2"). Is it best to zone each HBA using one-to-one, or create one big zone set with all four XtremIO FC connections and my Server HBA?   Does our servers see storage from both X-Bricks? If so would we just zone one server to one X-Brick? Looking for guidance, whitepapers, best practices, etc...   Switch "Fabric A" aliases   "UCS01_HBA1"     "X1_SC1_A" "X1_SC2_A" "X2_SC1_A" "X2_SC2_A"  Switch "Fabric B" aliases "UCS01_HBA2" "X1_SC1_B" "X1_SC2_B" "X2_SC1_B" "X2_SC2_B"  Thank You Terry
