MSA 2040 Storage models 11
1 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)
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
Alternatively, you can use the management interfaces to set Converged Network Controller ports to support
a combination of host interface protocols. When configuring a combination of host interface protocols,
host ports 1 and 2 are set to FC (either both16 Gbit/s or both 8 Gbit/s), and host ports 3 and 4 must be
set to iSCSI (either both 10 GbE or both 1 GbE), provided the Converged Network Controller ports use the
qualified SFP connectors and cables required for supporting the selected host interface protocol. See
"MSA 2040 SAN controller module—rear panel LEDs" (page 77) for more information.
IMPORTANT: See the “HP MSA 2040 SAN Storage array and iSCSI SFPs Read This First” document for
important information pertaining to iSCSI SFPs.
TIP: See the “Configuring host ports” topic within the SMU Reference Guide for information about
configuring Converged Network Controller ports with host interface protocols of the same type or a
combination of types.
MSA 2040 SAS
MSA 2040 SAS models provide four high density mini-SAS (HD mini-SAS) ports per controller module. The
HD mini-SAS host interface protocol uses the SFF-8644 external connector interface defined for SAS3.0 to
support a link rate of 12 Gbit/s using the qualified connectors and cable options. See "MSA 2040 SAS
controller module—rear panel LEDs" (page 79) for more information.
