3.3 Connection

3.3.1 Overview

Check the following before connecting the disk array unit:
1. Connection cables
 To connect the disk array unit and a disk enclosure, be sure to use the cables that come with the
disk enclosure or SAS cables specified by NEC.
 (For FC) To connect a host bus adapter or FC switch on an application server to the disk array
unit, be sure to use an FC cable specified by NEC.
 (For 1Gbps iSCSI) To connect an NIC or switch on an application server to the disk array unit, be
sure to use a LAN cable in the category 5e or over.
(For 10Gbps iSCSI) To connect an NIC or switch on an application server to the disk array unit,

be sure to use an optical Ethernet cable (conforming to 10GBASE-SR).
 To connect the disk array to power supply, use the power supply cables that come with the disk
array unit.
