The LUN queue depth setting per path in a customer’s environment configured with a dual X-Brick cluster, 8 ESXi hosts with 2 Emulex HBAs, each ESXi host having 8 LUNs, and each LUN visible through 4 paths, should be set to1281.
This is based on the best practice recommendation for Emulex HBAs in an XtremIO environment, as mentioned in the Dell Community1.The LUN queue depth on the Emulex HBA should be set to 1281.However, this setting might need to be adjusted based on the specific storage environment and the other storage arrays that are being used12.
