•“Controller enclosure—rear panel layout” (page 62)

•“MSA 1050 controller module—rear panel LEDs” (page 63)

The MSA 1050 enclosures support virtual storage. For virtual storage, a group of disks with an assigned RAID level is called a virtual disk group. This guide uses the term disk group for brevity.

MSA 1050 enclosure user interfaces

The MSA 1050 enclosures support the Storage Management Utility (SMU), which is a web-based application for configuring, monitoring, and managing the storage system. Both the SMU and the command-line interface (CLI) are briefly described.

•The SMU is the primary web interface to manage virtual storage.

•The CLI enables you to interact with the storage system using command syntax entered via the keyboard or scripting.

NOTE: For more information about the SMU, see the SMU Reference Guide or online help. For more information about the CLI, see the CLI Reference Guide. See also “Related MSA documentation” (page 9).

MSA 1050 controllers

The MSA 1050 controller enclosures are pre-configured at the factory to support one of these host interface protocols:

•8 Gb FC

•1 GbE iSCSI

•10 GbE iSCSI

•12 Gb HD mini-SAS

For FC and iSCSI host interfaces, the small from-factor pluggable (SFP transceiver or SFP) connector supporting the pre-configured host interface protocol is pre-installed in the controller module. MSA 1050 controller enclosures do not allow you to change the host interface protocol or increase speeds. Always use qualified SFP connectors and cables for supporting the host interface protocol as described in the QuickSpecs. See also “Product QuickSpecs” (page 9).

For the HD mini-SAS host interface, both standard and fan-out cables are supported for host connection. Always use qualified SAS cable options for supporting the host interface protocol as described in QuickSpecs. Host connection for this controller module is described by cabling diagrams in “Connecting hosts” . Connection information for the SAS fan-out cable options is provided in “SAS fan-out cable option” .

2Components

Front panel components

HPE MSA 1050 models support small form factor (SFF) and large form factor (LFF) enclosures. The SFF chassis, configured with 24 2.5" SFF disks, and the LFF chassis, configured with 12 3.5" LFF disks, are used as either controller enclosures or drive enclosures.

Supported drive enclosures, used for adding storage, are available in LFF or SFF chassis. The MSA 2050 LFF Disk Enclosure is the large form factor drive enclosure and the MSA 2050 SFF Disk Enclosure is the small form factor drive enclosure used for storage expansion.

HPE MSA 1050 models use either an enclosure bezel or traditional ear covers. The 2U bezel assembly is comprised of left and right ear covers connected to the bezel body subassembly. A sample bezel is shown below.

Figure 1 Bezel used with MSA 1050 enclosures: front panel

The front panel illustrations that follow show the enclosures with the bezel removed, revealing ear flanges and disk drive modules. Two sleeves protruding from the backside of each ear cover component of the bezel assembly push-fit onto the two ball studs shown on each ear flange to secure the bezel. Remove the bezel to access the front panel components.

TIP: See “Enclosure bezel” (page 58) for bezel attachment and removal instructions, and pictorial views.

Figure 4 MSA 1050 Array: rear panel

A controller enclosure accommodates a power supply FRU in each of 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: MSA 1050 controller enclosures support dual-controller only. If a partner controller fails, the array will fail over and run on a single controller until redundancy is restored. A controller module must be installed in each IOM slot to ensure sufficient airflow 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 1050 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 1050 controller enclosures for expanding storage capacity.

NOTE: MSA 1050 controller enclosures support hot-plug replacement of redundant controller modules, fans, power supplies, disk drives, and I/O modules. Hot-add of drive enclosures is also supported.

14 Components

Cache

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

•Write-back 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 the 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 memory card is located at the midplane-facing end of the controller module as shown below.

Controller module pictorial (Midplane-facing rear view)

CompactFlash memory card

Figure 9 MSA 1050 CompactFlash memory card

If one controller fails, then later another controller fails 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” (page 45) for more information).

Cache 15

CAUTION: The CompactFlash memory 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 HPE 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.

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, provided that volume cache is set to standard on all volumes in the pool owned by the failed controller.

Supercapacitor pack

To protect RAID controller cache in case of power failure, MSA 1050 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 1050 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. Straight-through cabling does not provide the same level of fault-tolerance as fault-tolerant cabling, but does provide some performance benefits as well as ensuring that all disks are visible to the array. Fault tolerance and performance requirements determine whether to optimize the configuration for high availability or high performance when cabling. MSA 1050 controller enclosures support 12 Gb/s disk drives downshifted to 6 Gb/s. Each enclosure has an expansion port using 6 Gb/s SAS lanes. 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 20) 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).

Installation checklist

Connecting the MSA 1050 controller to the LFF or SFF drive enclosure

The MSA 2050 LFF Disk Enclosure and the MSA 2050 SFF Disk Enclosure can be attached to an MSA 1050 controller enclosure using supported mini-SAS to mini-SAS cables of 0.5 m (1.64') to 2 m (6.56') length [see Figure 10 (page 20)]. Each drive enclosure provides two 0.5 m (1.64') mini-SAS to mini-SAS cables. Longer cables may be desired or required, and can be purchased separately.

Cable requirements for MSA 1050 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.

•See the QuickSpecs for information about which cables are provided with your MSA 1050 products.

www.hpe.com/support/MSA1050QuickSpecs

(If a website location has changed, an Internet search for “HPE MSA 1050 quickspecs” will provide a link.)

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

•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 (see QuickSpecs for supported cables):

Spanning 3 or 4 drive enclosures requires 1 m (3.28') cables.

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

Qualified Fibre Channel cable options

Qualified 10GbE iSCSI cable options or qualified 10GbE Direct Attach Copper (DAC) cables

Qualified 1 Gb RJ-45 cable options

Qualified HD mini-SAS standard cable and fan-out cable options supporting SFF-8644 and SFF-8088 host connection [also see “12 Gb SAS protocol” (page 25)]:

–SFF-8644 to SFF-8644 cable option is used for connecting to a 12 Gb/s enabled host.

–SFF-8644 to SFF-8088 cable option is used for connecting to a 6 Gb/s enabled host/switch.

–A bifurcated SFF-8644 to SFF-8644 fan-out cable option is used for connecting to a 12Gb/s enabled host.

–A bifurcated SFF-8644 to SFF-8088 fan-out cable option is used for connecting to a 6Gb/s enabled host/switch.

NOTE: Using fan-out cables instead of standard cables will double the number of hosts that can be attached to a single system. Use of fan-out cables will halve the maximum bandwidth available to each host, but overall bandwidth available to all hosts is unchanged.

See SAS fan-out cable option for more information about bifurcated SAS cables.

NOTE: For clarity, the schematic illustrations of controller and expansion modules shown in this section provide only relevant details such as expansion ports within the module face plate outline. For detailed illustrations showing all components, see “Controller enclosure—rear panel layout” (page 12).

IMPORTANT: MSA 1050 controller enclosures support dual-controller only. If a partner controller fails, the array will fail over and run on a single controller until the redundancy is restored. A controller module must be installed in each IOM slot to ensure sufficient airflow through the enclosure during operation.

Figure 11 Cabling connections between MSA 1050 controllers and LFF and SFF drive enclosures

The diagram at left (above) shows fault-tolerant cabling of a dual-controller enclosure cabled to either the

MSA 2050 LFF Disk Enclosure or the MSA 2050 SFF Disk Enclosure 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.

20 Installing the enclosures

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

Figure 11 (page 20) provides example diagrams reflecting fault-tolerant (left) and straight-through (right) cabling for the maximum number of supported MSA 1050 enclosures (four enclosures including the controller enclosure).

IMPORTANT: For comprehensive configuration options and associated illustrations, refer to the HPE MSA 1050 Cable Configuration Guide.

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 23).

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: Power supplies used in MSA 1050 enclosures

The MSA 1050 controller enclosures and drive enclosures are equipped with AC power supplies that do not have power switches (they are switchless). They power on when connected to a power source, and they power off when disconnected.

•When powering up, make sure to power up the enclosures and associated 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 58) 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.

Hosts last (if powered down for maintenance purposes)

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

IMPORTANT: See “Power cord requirements” (page 72) and the QuickSpecs for more information about power cords supported by MSA 1050 enclosures.

Testing enclosure connections

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.

Power cord connect

Figure 12 AC power supply

AC power cycle

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 12). 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 12). 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 41)].

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

Use the SMU to shut down both controllers, as described in the online help and web-posted HPE MSA 1050/2050 SMU Reference Guide.

Proceed to step 3.

Use the CLI to shut down both controllers, as described in the HPE MSA 1050/2050 CLI Reference Guide.

3.Disconnect the power cord female plug from the power cord connector on the power supply module. Perform this step for each power supply module (controller enclosure first, followed by drive enclosures).

22 Installing the enclosures

4Connecting hosts

Host system requirements

Data hosts connected to HPE MSA 1050 arrays must meet requirements described herein. Depending on your system configuration, data host operating systems may require that multi-pathing is supported.

If fault-tolerance is required, then multi-pathing software may be required. Host-based multi-path software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time. This would include most configurations where there are multiple connections to the host or multiple connections between a switch and the storage.

•Use native Microsoft MPIO DSM support with Windows Server 2016 and Windows Server 2012. Use either the Server Manager or the command-line interface (mpclaim CLI tool) to perform the installation. Refer to the following web sites for information about using Windows native MPIO DSM:

http://support.microsoft.com

http://technet.microsoft.com (search the site for “multipath I/O overview”)

•Use the HPE Multi-path Device Mapper for Linux Software with Linux servers. To download the appropriate device mapper multi-path enablement kit for your specific enterprise Linux operating system, go to www.hpe.com/storage/spock.

Connecting the enclosure to data hosts

A host identifies an external port to which the storage system is attached. The external port may be a port in an I/O adapter (such as an FC HBA) in a server. Cable connections vary depending on configuration. Common cable configurations are shown in this section. A list of supported configurations is available on the Hewlett Packard Enterprise site at: www.hpe.com/support/msa1050:

•HPE MSA 1050 Quick Start Instructions

•HPE MSA 1050 Cable Configuration Guide

These documents provide installation details and describe supported direct attach, switch-connect, and storage expansion configuration options for MSA 1050 products. For specific information about qualified host cabling options, see “Cable requirements for MSA 1050 enclosures” (page 18).

MSA 1050 Storage host interface protocols

The small form-factor pluggable (SFP transceiver of SFP) connectors used in pre-configured host ports of FC and iSCSI MSA 1050 models are further described in the subsections below. Also see “MSA 1050 Storage models” (page 8) for more information concerning use of these host ports.

NOTE: MSA 1050 FC and iSCSI controllers support the optionally-licensed Remote Snap replication feature. Remote Snap supports FC and iSCSI host interface protocols for replication. Use the SMU or CLI commands to create and view replication sets.

MSA 1050 SAS models use high-density mini-SAS (Serial Attached SCSI) interface protocol for host connection. These models do not support Remote Snap replication.

Fibre Channel protocol

The MSA 1050 controller enclosures support two controller modules using the Fibre Channel interface protocol for host connection. Each controller module provides two host ports designed for use with an FC SFP supporting data rates up to 8 Gb/s. MSA 1050 FC controllers can also be cabled to support the optionally-licensed Remote Snap replication feature via the FC ports.

Host system requirements

The MSA 1050 FC controllers support Fibre Channel Arbitrated Loop (public or private) or point-to-point topologies. Loop protocol can be used in a physical loop or in a direct connection between two devices. Point-to-point protocol is used to connect to a fabric switch. Point-to-point protocol can also be used for direct connection. See the set host-parameters command within the CLI Reference Guide for command syntax and details about connection mode parameter settings relative to supported link speeds.

Fibre Channel ports are used in either of two capacities:

•To connect two storage systems through a Fibre Channel switch for use of Remote Snap replication.

•For attachment to FC hosts directly, or through a switch used for the FC traffic.

The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second option requires that the host computer supports FC and optionally, multipath I/O.

TIP: Use the SMU Configuration Wizard to set FC port speed. Within the SMU Reference Guide, see “Using the Configuration Wizard” and scroll to FC port options. Use the set host-parameters CLI command to set FC port options, and use the show ports CLI command to view information about host ports.

10GbE iSCSI protocol

The MSA 1050 controller enclosures support two controller modules using the Internet SCSI interface protocol for host connection. Each controller module provides two host ports designed for use with a 10GbE iSCSI SFP or approved DAC cable supporting data rates up to 10 Gb/s, using either one-way or mutual CHAP (Challenge-Handshake Authentication Protocol).

TIP: See the topics about configuring CHAP, and CHAP and replication in the SMU Reference Guide.

TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see “Using the Configuration Wizard” and scroll to iSCSI port options. Use the set host-parameters CLI command to set iSCSI port options, and use the show ports CLI command to view information about host ports.

The 10GbE iSCSI ports are used in either of two capacities:

•To connect two storage systems through a switch for use of Remote Snap replication.

•For attachment to 10GbE iSCSI hosts directly, or through a switch used for the 10GbE iSCSI traffic.

The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second option requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.
