Rack Installation Requirements
Direct Attach Cable (Twinax SFP+ Cable)
For the ETERNUS AX/HX series, one controller is equivalent to one node and a high availability (HA) pair com-
prises two nodes. To configure HA pairs, a "direct attach cable" (10Gb, SFP+/SFP+, 0.5m) must be used for connec-
tions between nodes.
Two 0.5 m direct attach cables are provided with each controller self.

Cables Used Between Nodes and Switches
For the ETERNUS AX/HX series, a cluster comprises multiple HA pairs.
For a cluster configured with two or more HA pairs (four or more nodes), the cluster network connection must be
used.
Cluster switches are used for the cluster network connection.
Cluster switches are also used for the MetroCluster configuration.
Two cluster switches are used for each cluster system.
