EqualLogic Terminology
The EqualLogic PS series storage array includes storage virtualization
technology. To better understand how these arrays operate, it is helpful to
be familiar with some of the terminology used to describe these arrays and
their functions:
• Member — a single PS series array
•
Group — a set of one or more members that can be centrally managed;
host systems access the data through a single group IP address
•
Pool — a RAID that can consist of the disks from one or more members
•
Volume — a LUN or virtual disk that represents a subset of the capacity
of a pool
Setting up the Dell EqualLogic iSCSI
Storage System
Host systems can be attached to the Dell™ EqualLogic PS5000XV iSCSI
array through an IP SAN industry-standard Gigabit Ethernet switch.
Figure 5-1 shows the recommended network configuration for a dual control
module Dell EqualLogic PS5000XV array. This configuration includes two
Dell PowerConnect™ 6200 series Gigabit Ethernet switches to provide the
highest network availability and the maximum network bandwidth.
