1 Introduction

Seagate Exos E expansion enclosures combine strong performance with high reliability, flexibility, and manageability. Powerful

and compact, the series expandable storage solution supports business with high-capacity and high-availability options.

The system is designed for high availability (HA), with no single point of failure for data or power. Input/output modules

(IOMs) are Storage Bridge Bay (SBB) v2.1 compatible for interconnects, power budgets and rails, form factors, and footprints.

WARNING! Heed all warnings and cautions on labeling and throughout this guide to reduce risk of personal injury or

damage to equipment. You must adhere to all safety requirements in this document. Some relate to the entire system, some to

the rack, some to the storage or expansion enclosure, and others to the FRUs within it.

Knowledge prerequisites

2 System overview

The Seagate Exos E expansion series enclosures consist of a sheet metal chassis that contains an integrated midplane and

module runner system. You can mount the expansion enclosure into a standard 19-inch rack cabinet, occupying either two

(2U) or five (5U) EIA rack space units. All plug-in modules are hot-swappable, but you must adhere to all safety precautions

and time limitations.

Type Typical set of plug-in modules Maximum expansions

2U12 expansion enclosure 2U chassis and rackmount railkit Up to 12

12 3.5-inch large form factor (LFF) drive modules in carriers (DDICs)

Two input/output modules (IOMs)

Two power cooling modules (PCMs)

2U24 expansion enclosure 2U chassis and rackmount railkit Up to 6

24 2.5-inch small form factor (SFF) DDICs

Two input/output modules (IOMs)

Two power cooling modules (PCMs)

5U84 expansion enclosure 5U chassis and rackmount railkit:

Contains two drawers, each with 42 drive modules

Up to 4

84 3.5-inch or 2.5-inch drive modules with adapters in carriers

Two input/output modules (IOMs)

Five fan cooling modules (FCMs)

Two power supply units (PSUs)

Four sideplane printed circuit boards (PCBs), two per drawer

Authorized service personnel only

Table 1 Expansion enclosure variations

Expansion enclosures can be configured as either an EBOD or a JBOD. An EBOD is an expansion enclosure attached to a

controller enclosure (RBOD). A JBOD is an expansion enclosure attached directly to a server that is equipped with a SAS HBA

or SAS RAID adapter.

CAUTION Make sure you are not connected to power at any time during installation procedures.

CAUTION Only operate the expansion enclosure in a dust-free environment to meet temperature control and airflow

requirements.

Expansion enclosure components

All Seagate Exos E expansion enclosures have 2 main access points:

1. Front panel area — Contains the operator's (ops) panel and access to drive modules in their carriers (DDICs)

a. 2U enclosures — Direct access to DDICs

b. 5U enclosures — Access to DDICs by opening the related drawer

2. Rear panel area — Contains input/output modules and methods for cooling and powering the expansion enclosure
