Deployment/Configuration Guide
4.3 Dell Compellent Storage Array Configuration
The Dell Compellent Storage Center controllers are used to support various I/O adapters including FC,
iSCSI, FCoE, and SAS. A Dell Compellent Storage Center consists of one or two controllers, FC switches,
and one or more enclosures. In the current example, two Compellent SC8000 controllers, one
Compellent SC220 enclosure, two FC switches, and one 4-port FC HBA card on each Compellent
controller is used for the SAN network. The FC switches provide robust connectivity to servers, allowing
for the use of multiple controllers and redundant transport paths.
SAS enclosures hold disks for data storage and connect to the controllers through back-end ports via
SAS cables; you can see how the SC220 enclosure and controllers are cabled together in Figure 5 prior
in this document.
To keep the diagram uncluttered yet detailed, the only connections not shown are the eth0 ports on
each controller connecting to the management network and the eth1 port on each controller
connecting to the eth1 port on the other controller. The eth0 connection supports system login and
access for the software. It’s used to send emails, alerts, SNMP traps, and Phone Home data. The eth1
connection is used for dedicated Inter-Process Communication (IPC) between controllers in a dual-
controller Storage Center. There is no default gateway for eth1 and it does not need to be set. See the
“CT-SC040 and SC8000 Connectivity Guide” and “Compellent Storage Center System Setup Guide” to
get started on cabling and configuring your Compellent storage array.
In this example setup, two SC8000 controllers and one SC220 disk enclosure have been cabled
together. There are two paths available from the server to the FC switches and four paths available from
each FC switch to the Compellent storage array.
1. During initial configuration of the Compellent Storage Center, a disk pool labeled Pool_1 was
created consisting of seven 300 GB drives. The total disk space is 1.64 TB; this can be seen in the
screen shot of the Storage Center System Manager GUI as shown below in Figure 28.
