1 Introduction
Quantum QXS storage enclosures combine strong performance with high reliability, flexibility, and
manageability. Powerful and compact, the LX2 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. Controller
modules (CMs) are Storage Bridge Bay (SBB) v2.1 compatible for interconnects, power budgets and rails,
form factors, and footprints.
All Quantum storage enclosures contain one or more CMs, which each contain a Hewitt Lake processor, 16GB
of cache, and a custom RAID acceleration ASIC.
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 enclosure, and others to the FRUs within it.

Table 1 Storage enclosure variations
You can use the 2U or 5U chassis as a controller storage enclosure when configured with controller modules,
or as an expansion enclosure when configured with input/output modules.
CAUTION Make sure you are not connected to power at any time during installation procedures.
CAUTION Only operate the storage enclosure in a dust-free environment to meet temperature control
and airflow requirements.
For optimum function, use the high availability (HA) model that requires dual paths for data and power to
increase fault tolerance and minimize single points of failure. This manual assumes HA model system
integration using a minimum of one fully populated storage enclosure.
Storage enclosure components
All Quantum QXS storage 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)

Chapter 2 System overview 3
a. 2U enclosures — Direct access to DDICs
b. 5U enclosures — Access to DDICs by opening the related drawer
2. Rear panel area — Contains controller modules and methods for cooling and powering the storage
enclosure
Storage enclosure chassis
Chassis sheet metal is bonded and riveted together and free from non-conductive coatings. Each chassis is
designed specifically for mounting in a rack cabinet.
2U enclosure components

Controller module components
Both controller modules (CMs) manage the flow of data to and from the storage enclosure. Each CM provides
a very specialized, solutions-specific interaction that depends on your system configuration and software
implementation, including RAIDfunctions, management functions, failover and failback procedures, and
multipath procedures.

Chapter 2 System overview 9
The CM has a number of ports and any related LEDs. See "Interpret controller module LEDs" on page52.

Optional components
Occasionally, you may configure the storage enclosure to operate without all of its components. The most
common reason is to perform in-field maintenance. Temperature and airflow requirements for 2U enclosures
mandate you immediately use blanks to replace modules you remove and adhere to all specified time
limitations for replacement.
lCarrier blank— For 2U enclosures not fully populated, occupies any empty drive slot to secure proper airflow
lController blank— For 2U enclosures configured with a single controller, occupies the empty controller slot
to secure proper airflow

10Chapter 3 Initial install preparations
3 Initial install preparations
Each storage enclosure installation requires the same amount of preparation to successfully mount it into your
industry-standard rack cabinet of up to 1.2m in depth.
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
