accompany with firmware.
A server with a SCSI HBA.
SCSI cables and terminators.
CAT 5, CAT 5e, or CAT 6 network cables for management port.
Prepare storage system configuration plan.
Management port network information. If using static IP, please

2.2 Storage introduction
Storage has two ”ends” in the connection. These ends are the initiator and the
target. The initiator: Requests, or initiates, any SCSI communications. It requests
all SCSI operations like read or write. An initiator is usually located on the
host/server side (an SCSI HBA).
Figure 2.2.1
The target is the storage device itself or an appliance that controls and serves
volumes or virtual volumes. The target is the device that performs the SCSI
command or bridges it to an attached storage device. The targets can be disks,
tapes, RAID arrays, tape libraries, etc.
