1Overview

HP MSA Storage models are high-performance storage solutions combining outstanding performance with high reliability, availability, flexibility, and manageability. MSA 1040 enclosure models are designed to meet NEBS Level 3, MIL-STD-810G (storage requirements), and European Telco specifications.

MSA 1040 Storage models

The MSA 1040 controller 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 1040 Storage models are pre-configured at the factory to support one of these host interface protocols:

• 8 Gb FC

• 4 Gb FC

• 10 G bE i S CS I

• 1 GbE iSCSI

The small form-factor pluggable (SFP transceiver or SFP) supporting the pre-configured host interface protocol is pre-installed in the controller module. MSA 1040 controller enclosures do not allow you to change host interface protocols or increase speeds. Always use qualified SFP connectors and cables required for supporting the host interface protocol as described in QuickSpecs.

MSA 1040 enclosures support LFF/SFF Midline SAS, LFF/SFF Enterprise SAS, and SFF SSD disks. For information about creating vdisks and adding spares using these different disk drive types, see the HP MSA 1040 SMU Reference Guide and HPSEDDrivesReadThisFirst document.

Controller enclosure—rear panel layout

The diagram and table below display and identify important component items comprising the rear panel layout of the MSA 1040 controller enclosure.

1 AC Power supplies 2 Controller module A (see face plate detail figures)

4 DC Power supply (2) — (DC model only) 5 DC Power switch

3 Controller module B (see face plate detail figures)

Figure 3 MSA 1040 Array: rear panel

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 1040 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 1040 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 1040 controller enclosures for expanding storage capacity.

NOTE: MSA 1040 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.

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 1040 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.

16 Components

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

Controller module pictorial

CompactFlash card

(Midplane-facing rear view)

Figure 7 MSA 1040 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 51) for more information).

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 1040 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.

Connecting controller and drive enclosures

MSA 1040 controller enclosures support up to four 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 1040 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 10 (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 (4B) of the last drive enclosure, with connections moving in the opposite direction (green).

Connecting the MSA 1040 controller to the SFF drive enclosure

The SFF D2700 25-drive enclosure, supporting 6 Gb internal disk drive and expander link speeds, can be attached to an MSA 1040 controller enclosure using supported mini-SAS to mini-SAS cables of 0.5 m (1.64') to 2 m (6.56') length [see Figure 9 (page 21)].

Connecting the MSA 1040 controller to the LFF drive enclosure

The LFF MSA 1040 6 Gb 3.5"12-drive enclosure, supporting 6 Gb internal disk drive and expander link speeds, can be attached to an MSA 1040 controller enclosure using supported mini-SAS to mini-SAS cables of 0.5 m (1.64') to 2 m (6.56') length [see Figure 9 (page 21)].

Connecting the MSA 1040 controller to mixed model drive enclosures

MSA 1040 controllers support cabling of 6 Gb SAS link-rate LFF and SFF expansion modules—in mixed model fashion—as shown in Figure 12 (page 24), and further described in the HP MSA 1040 Cable Configuration Guide; the HP MSA 1040 Quick Start Instructions; QuickSpecs; and HP white papers (listed below).

Cable requirements for MSA 1040 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 1040 products.

http://www.hp.com/support/msa

• If additional or longer cables are required, they must be ordered separately (see relevant MSA 1040

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 drive enclosures requires 1 m (3.28') cables.

Figure 8 Cabling connections between the MSA 1040 controller and a single drive enclosure

The figure above shows examples of the MSA 1040 controller enclosure—equipped with a single controller module—cabled to a single drive enclosure equipped with a single expansion module. The empty I/O module slot in each of the enclosures is covered with an IOM blank to ensure sufficient air flow during enclosure operation. The remaining illustrations in the section feature enclosures equipped with dual IOMs.

IMPORTANT: If the MSA 1040 controller enclosure is configured with a single controller module, the

controller module must be installed in the upper slot, and an I/O module blank must be installed in the lower slot (shown above). This configuration is required to allow sufficient air flow through the enclosure during operation.

The diagram at left (above) shows fault-tolerant cabling of a dual-controller enclosure cabled to MSA 2040 6 Gb 3.5" 12-drive enclosures featuring dual-expansion modules. Controller module 1A is connected to expansion module 2A, with a chain of connections cascading down (blue). Controller module 1B is connected to the lower expansion module (4B) of the last drive enclosure, with connections moving in the opposite direction (green). Fault-tolerant cabling allows any drive enclosure to fail—or be removed—while maintaining access to other enclosures.

The diagram at right (above) shows the same storage components connected using straight-through cabling. Using this method, if a drive enclosure fails, the enclosures that follow the failed enclosure in the chain are no longer accessible until the failed enclosure is repaired or replaced.

Both illustrations in Figure 10 show the maximum number of supported enclosures that can be cabled together in an MSA 1040 system configuration: up to four enclosures (including the controller enclosure).

Figure 12 Cabling connections between MSA 1040 controllers and drive enclosures of mixed model type

The figure above provides sample diagrams reflecting cabling of MSA 1040 controller enclosures and supported mixed model drive enclosures. In this example, the SFF drive enclosures follow the LFF 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 1040 controller enclosures support up to four enclosures (including the controller enclosure) for adding storage. Both illustrations in Figure 12 show the maximum number of supported enclosures that can be cabled together in an MSA 1040 system configuration.

IMPORTANT: For comprehensive configuration options and associated illustrations, refer to the HP MSA

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 29).

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 1040 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—

and back of the enclosure are amber— detected. See "LED descriptions" (page 67) 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)

if no LEDs on the front

the power-on sequence is complete, and no faults have been

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 26).

IMPORTANT: See "Power cord requirements" (page 78) and QuickSpecs for more information about

power cords supported by MSA 1040 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.

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 13).

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 13). 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 47)].

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 1040 SMU Reference Guide.

Proceed to step 3.

• Use the command-line interface (CLI) to shut down both controllers, as described in the HP MSA 1040 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.

NOTE: Power cycling for enclosures equipped with a power switch is described below.
