Overview

HP MSA Storage models are high-performance storage solutions combining outstanding performance with
high reliability, availability, flexibility, and manageability. MSA 2040 enclosure models are designed to
meet NEBS Level 3, MIL-STD-810G (storage requirements), and European Telco specifications.

MSA 2040 Storage models

The MSA 2040 enclosures support either large form factor (LFF 12-disk) or small form factor (SFF 24-disk)
2U chassis, using either AC or DC power supplies. HP MSA Storage models include MSA 2040 SAN and
MSA 2040 SAS controllers, which are introduced below.
NOTE: For additional information about MSA 2040 controller modules, see the following subsections:
• "Controller enclosure—rear panel layout" (page 14)
• "MSA 2040 SAN controller module—rear panel components" (page 15)
• "MSA 2040 SAS controller module—rear panel components" (page 16)
The MSA 2040 enclosures support both traditional linear storage and new virtual storage, which uses
paged-storage technology. For linear storage, a group of disks with an assigned RAID level is called a
vdisk or linear disk group. For virtual storage, a group of disks with an assigned RAID level is called a
virtual disk group. This guide uses the term vdisk when specifically referring to linear storage, and uses the
term disk group otherwise.
MSA 2040 enclosure user interfaces
The MSA 2040 enclosures support two versions of the Storage Management Utility (SMU), which is a
web-based application for configuring, monitoring, and managing the storage system. Both SMU versions
(v3 and v2) and the command-line interface are briefly described.
• v3 is the new primary web interface for the enclosures, providing access to all common management
functions for both linear and virtual storage.
• v2 is a secondary web interface for the enclosures, providing access to traditional linear storage
functions. This legacy interface provides certain functionality that is not available in the primary
interface.
• The command-line interface (CLI) enables you to interact with the storage system using command syntax
entered via the keyboard or scripting. You can set a CLI preference to use v3 or v2 terminology in
command output and system messages.
NOTE: For more information about the web-based application, see the HP MSA 2040 SMU Reference
Guide or online help. For more information about the CLI, see the HP MSA 2040 CLI Reference Guide.

MSA 2040 SAN

MSA 2040 SAN models use Converged Network Controller technology, allowing you to select the desired
host interface protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface
protocols supported by the system. You can use the CLI to set all controller module host ports to use one of
these host interface protocols:
• 16 Gb FC
• 8 Gb FC
• 4 Gb FC
• 10 GbE iSCSI
• 1 GbE iSCSI
