Introduction to PS Series Storage Arrays

EqualLogic PS Series storage arrays deliver the benefits of consolidated storage in a storage area network (SAN) that is affordable and easy to use—regardless of its size. With intelligent, automated management and fast, flexible scalability,

PS Series arrays greatly reduce storage acquisition and management costs. This QuickStart describes how to start using your PS Series array.

By grouping together one or more PS Series arrays connected to an IP network, you can create a PS Series group—a highly-scalable iSCSI SAN with a shared pool of storage space. Integrated virtualization software makes a group easy to manage and provides automatic RAID configuration, data provisioning, and load balancing. To increase SAN capacity and performance, connect another array to the network and add it to the group—data remains online at all times.

To ensure high reliability, PS Series storage arrays include RAID-protected disks, automatic disk sparing, redundant fans and power supplies, and dual high-performance control modules, each with three Gigabit Ethernet interfaces and a battery-backed cache.

A simple setup utility lets you quickly configure an array as a member of a new or existing group. RAID configuration and load balancing (network and data) occur automatically. Both graphical and command line user interfaces are available for group management.

In a multi-member group, you can separate space into storage pools, which allow you to organize storage according to usage, providing more control over resource allocation, while maintaining a single system management view.

Using the Group Manager graphical or command line user interface, you create volumes, assigning to each volume a pool, size, access controls, and other attributes. A volume can be spread across multiple disks and group members and is seen on the network as an iSCSI target. Members and volumes can move between pools to meet business objectives.

To connect to a volume, a host needs only a standards-compliant iSCSI initiator. Volume access can be restricted through IP address, initiator name, or CHAP (Challenge Handshake Authentication Protocol) credentials. Once connected, the volume is seen by the host as a regular disk that can be formatted as usual.

PS Series 3000 QuickStart

Steps for Setting Up and Using an Array

At a minimum, a group consists of one array with one network connection, but you can configure three network interfaces for maximum array bandwidth. Data and network I/O are automatically load balanced across disks and interfaces—with no impact on data availability.

PS Series Group With Multiple Members

You can easily increase group capacity and bandwidth by adding arrays. When an array is added to a group, it obtains the group configuration from the existing members. Once you choose a RAID policy for the member, the pool is automatically expanded, and volume data and network I/O are load balanced across the pool members’ disks and network connections. Volumes continue

to be accessible through the same iSCSI targets, and no host modifications are necessary. Management overhead remains the same, regardless of the group size.

Steps for Setting Up and Using an Array

To start using your PS Series array:

Step 1. Set up the array hardware configuration.

Step 2. Configure the array on the network and create a group.

Step 3. Log in to the group and specify the RAID policy for the array.

Step 4. Create a volume.

Step 5. Connect to the volume from a host system.

Step 1. Set Up the Array Hardware

A. Unpack Shipping Box and Gather Hardware

The order in which you unpack the shipping box is important for safety:

1.Open the outer shipping box and remove the accessory box.

2.Remove the accessories and ensure that you have the contents shown in the figure Shipping Box Contents.

3.Following the unpacking instructions in the shipping box, lift the array and place it on a flat surface that is protected from electrostatic discharge. Do not remove the plastic bag from the array until you are ready to install it in a rack.

4.Gather the hardware that is not included in the box, as described in the table
