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.

2 Components

Front panel components

HP MSA 2040 models support small form factor (SFF) and large form factor (LFF) enclosures. The SFF chassis, configured with 24 2.5" SFF disks, is used as a controller enclosure. The LFF chassis, configured with 12 3.5" LFF disks, is used as either a controller enclosure or a drive enclosure.

Supported drive enclosures, used for adding storage, are available in LFF or SFF chassis. The MSA 2040 6 Gb 3.5" 12-drive enclosure is the large form factor drive enclosure used for storage expansion. The HP D2700 6 Gb enclosure, configured with 25 2.5" SFF disks, is the small form factor drive enclosure used for storage expansion. See "SFF drive enclosure" (page 17) for a description of the D2700.

A controller enclosure accommodates two power supply FRUs of the same type—either both AC or both DC—within the two power supply slots (see two instances of callout 1 above). The controller enclosure accommodates two controller module FRUs of the same type within the I/O module slots (see callouts 2 and 3 above).

IMPORTANT: If the MSA 2040 controller enclosure is configured with a single controller module, the controller module must be installed in the upper slot (see callout 2 above), and an I/O module blank must be installed in the lower slot (see callout 3 above). This configuration is required to allow sufficient air flow through the enclosure during operation.

The diagrams with tables that immediately follow provide descriptions of the different controller modules and power supply modules that can be installed into the rear panel of an MSA 2040 controller enclosure. Showing controller modules and power supply modules separately from the enclosure provides improved clarity in identifying the component items called out in the diagrams and described in the tables. Descriptions are also provided for optional drive enclosures supported by MSA 2040 controller enclosures for expanding storage capacity.

NOTE: MSA 2040 controller enclosures support hot-plug replacement of redundant controller modules, fans, power supplies, and I/O modules. Hot-add of drive enclosures is also supported.

SFF drive enclosure

MSA 2040 controllers support the D2700 6 Gb drive enclosure for adding storage. For information about this product, visit http://www.hp.com/support. Pictorial representations of this drive enclosure are also provided in the MSA 2040 Quick Start Instructions and MSA 2040 Cable Configuration Guide.

Cache

To enable faster data access from disk storage, the following types of caching are performed:

•Write-back or write-through caching. The controller writes user data in the cache memory on the module rather than directly to the drives. Later, when the storage system is either idle or aging—and continuing to receive new I/O data—the controller writes the data to the drive array.

•Read-ahead caching. The controller detects sequential array access, reads ahead into the next sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the controller immediately loads the data into the system memory, avoiding the latency of a disk access.

NOTE: See HP MSA 2040 SMU Reference Guide for more information about volume cache options.

Transportable CompactFlash

During a power loss or array controller failure, data stored in cache is saved off to non-volatile memory (CompactFlash). The data is then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.

The CompactFlash card is located at the midplane-facing end of the controller module as shown below.

Controller module pictorial (Midplane-facing rear view)

CompactFlash card

Used	for Do not
	cache		remove
		recovery		only

Figure 8 MSA 2040 CompactFlash card

In single-controller configurations, if the controller has failed or does not start, and the Cache Status LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk (see "Controller failure in a single-controller configuration" (page 57) for more information).

Cache 17

CAUTION: The CompactFlash card should only be removed for transportable purposes. To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to the replacement controller using a procedure outlined in the HP MSA Controller Module Replacement Instructions shipped with the replacement controller module. Failure to use this procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual controller configurations featuring one healthy partner controller, there is no need to transport failed controller cache to a replacement controller because the cache is duplicated between the controllers (subject to volume write optimization setting).

Supercapacitor pack

To protect RAID controller cache in case of power failure, MSA 2040 controllers are equipped with supercapacitor technology, in conjunction with CompactFlash memory, built into each controller module to provide extended cache memory backup time. The supercapacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash in the event of a power failure. Unwritten data in CompactFlash memory is automatically committed to disk media when power is restored. While the cache is being maintained by the supercapacitor, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

Upgrading to MSA 2040

3If the systems are cabled for replication and licensed to use the Remote Snap feature, you can use the Replication Setup Wizard to prepare to replicate an existing volume to another vdisk. See the SMU Reference Guide for additional information.

Connecting controller and drive enclosures

MSA 2040 controller enclosures support up to eight enclosures (including the controller enclosure). You can cable drive enclosures of the same type or of mixed LFF/SFF model type.

The firmware supports both straight-through and fault-tolerant SAS cabling. Fault-tolerant cabling allows any drive enclosure to fail—or be removed—while maintaining access to other enclosures. Fault tolerance and performance requirements determine whether to optimize the configuration for high availability or high performance when cabling. MSA 2040 controller enclosures support 6 Gbit/s internal disk drive speeds, together with 6 Gbit/s (SAS2.0) expander link speeds. When connecting multiple drive enclosures, use fault-tolerant cabling to ensure the highest level of fault tolerance.

For example, the illustration on the left in Figure 11 (page 22) shows controller module 1A connected to expansion module 2A, with a chain of connections cascading down (blue). Controller module 1B is connected to the lower expansion module (5B) of the last drive enclosure, with connections moving in the opposite direction (green).

Cable requirements for MSA 2040 enclosures

IMPORTANT:

•When installing SAS cables to expansion modules, use only supported mini-SAS x4 cables with SFF-8088 connectors supporting your 6 Gb application.

•Mini-SAS to mini-SAS 0.5 m (1.64') cables are used to connect cascaded enclosures in the rack.

•See QuickSpecs for information about which cables are provided with your MSA 2040 products. http://www.hp.com/support/msa2040/QuickSpecs

•If additional or longer cables are required, they must be ordered separately (see relevant MSA 2040 QuickSpecs or P2000 G3 QuickSpecs for your products).

•The maximum expansion cable length allowed in any configuration is 2 m (6.56').

•Cables required, if not included, must be separately purchased.

•When adding more than two drive enclosures, you may need to purchase additional 1 m or 2 m cables, depending upon number of enclosures and cabling method used:

•Spanning 3, 4, or 5 drive enclosures requires 1 m (3.28') cables.

•Spanning 6 or 7 drive enclosures requires 2 m (6.56') cables.

•See Quickspecs (link provided above) regarding information about cables supported for host connection:

•Qualified Fibre Channel SFP and cable options

The illustration above shows a sample maximum enclosures configuration. The diagram shows mixed model drive enclosures within the dual-controller array using fault-tolerant cabling. In this example, the LFF drive enclosures follow the SFF drive enclosures. Given that both drive enclosure models use 6 Gb SAS link-rate and SAS2.0 expanders, they can be ordered in desired sequence within the array, following the controller enclosure. MSA 2040 controller enclosures support up to eight enclosures (including the controller enclosure) for adding storage.

IMPORTANT: For comprehensive configuration options and associated illustrations, refer to the HP MSA 2040 Cable Configuration Guide.

26 Installing the enclosures

Testing enclosure connections

NOTE: Once the power-on sequence for enclosures succeeds, the storage system is ready to be connected to hosts, as described in "Connecting the enclosure to data hosts" (page 31).

Powering on/powering off

Before powering on the enclosure for the first time:

•Install all disk drives in the enclosure so the controller can identify and configure them at power-up.

•Connect the cables and power cords to the enclosures as explained in the quick start instructions.

NOTE: MSA 2040 controller enclosures and drive enclosures do not have power switches (they are switchless). They power on when connected to a power source, and they power off when disconnected.

•Generally, when powering up, make sure to power up the enclosures and associated data host in the following order:

•Drive enclosures first

This ensures that disks in each drive enclosure have enough time to completely spin up before being scanned by the controller modules within the controller enclosure.

While enclosures power up, their LEDs blink. After the LEDs stop blinking—if no LEDs on the front and back of the enclosure are amber—the power-on sequence is complete, and no faults have been detected. See "LED descriptions" (page 73) for descriptions of LED behavior.

•Controller enclosure next

Depending upon the number and type of disks in the system, it may take several minutes for the system to become ready.

•Data host last (if powered down for maintenance purposes)

TIP: Generally, when powering off, you will reverse the order of steps used for powering on.

Power cycling procedures vary according to the type of power supply unit included with the enclosure. For controller and drive enclosures configured with the switchless AC power supplies, refer to the procedure described under AC power supply below. For procedures pertaining to a) controller enclosures configured with DC power supplies, or b) previously installed drive enclosures featuring power switches, see "DC and AC power supplies equipped with a power switch" (page 28).

IMPORTANT: See "Power cord requirements" (page 86) and QuickSpecs for more information about power cords supported by MSA 2040 enclosures.

AC power supply

Enclosures equipped with switchless power supplies rely on the power cord for power cycling. Connecting the cord from the power supply power cord connector to the appropriate power source facilitates power on; whereas disconnecting the cord from the power source facilitates power off.

Testing enclosure connections

27

Power cord connect

Figure 16 AC power supply

To power on the system:

1.Obtain a suitable AC power cord for each AC power supply that will connect to a power source.

2.Plug the power cord into the power cord connector on the back of the drive enclosure (see Figure 16). Plug the other end of the power cord into the rack power source. Wait several seconds to allow the disks to spin up.

Repeat this sequence for each power supply within each drive enclosure.

3.Plug the power cord into the power cord connector on the back of the controller enclosure (see Figure 16). Plug the other end of the power cord into the rack power source.

Repeat the sequence for the controller enclosure’s other switchless power supply.

To power off the system:

1.Stop all I/O from hosts to the system [see "Stopping I/O" (page 53)].

2.Shut down both controllers using either method described below:

•Use the SMU (Storage Management Utility) to shut down both controllers, as described in the online help and web-posted HP MSA 2040 SMU Reference Guide.

Proceed to step 3.

•Use the command-line interface (CLI) to shut down both controllers, as described in the HP MSA 2040 CLI Reference Guide.

3.Disconnect the power cord male plug from the power source.

4.Disconnect the power cord female plug from the power cord connector on the power supply.

N-m (15 in-lb) and 2.3 N-m (20 in-lb), to securely attach the cable to the DC power
supply module.	(left side view)

4.To complete the DC connection, secure the other end of each cable wire component of the DC power cable to the target DC power source.

Check the three individual DC cable wire labels before connecting each cable wire lug to its power source. One cable wire is labeled ground (GND) and the other two wires are labeled positive (+L) and negative (-L), respectively (shown in Figure 18 above).

CAUTION: Connecting to a DC power source outside the designated -48V DC nominal range (-36V DC to -72V DC) may damage the enclosure.

Connect power cord to legacy AC power supply

Obtain two suitable AC power cords: one for each AC power supply that will connect to a separate power source. See the illustration at right [in Figure 17 (page 28)] when performing the following steps:

1.Verify that the enclosure power switches are in the Off position.

2.Identify the power cord connector on the power supply, and locate the target power source.

3.For each power supply, perform the following actions:

a.Plug one end of the cord into the power cord connector on the power supply.

b.Plug the other end of the power cord into the rack power source.

4.Verify connection of primary power cords from the rack to separate external power sources.
