1  Basic Storage Array Information 
This chapter includes information about the location and basic operation of the replaceable 
components in a storage array, tools and equipment you will need, protecting hardware from 
electrostatic discharge, and power on and off operations. 
About the PS6610 Array 
The PS6610 array is a PS6x10 10GbE class EqualLogic PS Series array that continues the focus by 
Dell on industry-standard features and capabilities for the midrange iSCSI SAN market. PS Series 
Storage Arrays version 8.0 introduces the PS6610. 
PS6610 Features 
The PS6610 array is a 5U chassis that can be configured with either 42 or 84 drives. Both 2.5-inch 
and 3.5-inch drives are supported in either configuration. Features of the PS6610 include: 
•  Two hot-swappable Type 18 control modules, which contain increased memory (16GB per 
controller) and a more powerful processor than previous generation controllers. 
•  5U SAS Drive Enclosure 
•  Ethernet ports: 
–  Two pairs of 10Gb/s dual-media interfaces (10GBASE-T/SFP+) 
–  Ability to fall back to 1 GB/s interface (10GBASE-T ports only) 
•  Support for ReadyRails™ II 
Front-Panel Features and Indicators 
The main features of the front panel are shown in Figure 1 and identified in Table 1. The left and 
right sides of each drawer on the PS6610 each contain an anti-tamper lock (see Figure 2), a recessed 
handle for opening the drawer, and a sideplane status indicator (see Figure 3) that monitors the 
operation and activity of each sideplane. As you face the front of the chassis, an Enclosure Status 
Indicator is located on the left edge that provides status information for the entire array (see Figure 
4). 
•  Table 2 describes the sideplane status indicators located on the drawers. 
•  Table 3 describes the enclosure indicator.
