The network layer consists of the following switches:
The following figure shows the recommended FC connectivity between the host bus adapters (HBAs) and the FC switches. It also shows 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 those same FC switches.
