information, using an “A” designator for RAID arrays and a “D” designator for
disks in a JBOD array. For example, “StorEdge 3510F D1000” identifies a JBOD array
with SES firmware version 1000, and “StorEdge 3510F A1000” identifies a Sun
StorEdge 3510 FC RAID array with firmware version 1000.
For a list of supported racks and cabinets, refer to the release notes for the model of
array that you are installing. You can find these release notes at:

or

Reliability, availability, and serviceability (RAS) are supported by:
■ Redundant components
■ Notification of failed components
■ Components that are replaceable while the unit is online
For information about specifications and agency approvals, see “Sun StorEdge 3510
and 3511 FC Array Specifications” on page A-1.
1.2 Field-Replaceable Units (FRUs)
This section describes the FRUs contained in the Sun StorEdge 3510 and 3511 FC
Arrays.
1.2.1 RAID I/O Controller Modules
A dual-controller configuration offers increased reliability and availability because it
eliminates a single point of failure, the controller. In a dual-controller configuration,
if the primary controller fails, the array automatically fails over to the second
controller without an interruption of data flow.
Sun StorEdge 3510 and 3511 FC array I/O controller modules are hot-serviceable.
Sun StorEdge 3510 FC array RAID controller modules provide six Fibre Channel
ports. Sun StorEdge 3511 FC array I/O controller modules provide eight Fibre
Channel ports. Single- and dual-controller models are available, with the dual-
controller version supporting active/passive and active/active configurations. Each
RAID controller is configured with 1 gigabyte (Gbyte) of cache.
