The following figure shows the recommended FC connectivity between the HBAs and the FC switches and the connectivity between the FC switches and the XtremIO X2 storage array. As shown, each server HBA port connects to two separate FC switches, and the two front-end ports on each XtremIO X2 array controller connect to the same FC switches.
