Overview

About this document

This document contains cable configuration information for HPE MSA 2050 controller enclosures and

supported expansion disk enclosures. The information is for the person who installs, administers, and

troubleshoots servers and storage systems. HPE assumes that you are qualified in servicing and installing

computer equipment, and are trained in recognizing hazards in products and hazardous energy levels.

For complete information on installing and configuring your product, see the user guide provided with your

HPE MSA 2050. User documents are provided on the HPE MSA 2050 support website and with the product.

For the latest version of a document, see the HPE MSA 2050 support website: http://www.hpe.com/

support/msa2050.

Complete system example

The following figure shows an example of a dual-controller, direct-connect enclosure configuration with two

servers accessing the storage.

Two servers are direct-connected to a dual-controller HPE MSA 2050 array. The MSA 2050 array is in turn

connected to two dual-I/O module HPE MSA 2050 6Gb 3.5” large form factor (LFF) or 2.5" small form factor

(SFF) enclosures using Mini-SAS to Mini-SAS cables.

Configuration notes

• A maximum of eight enclosures (including the controller enclosure) are allowed in the storage system.

• For Windows computers that are connected to the MSA 2050 controller CLI port, a special device driver

file must be downloaded and installed on the Windows computer prior to using the CLI port. This device

driver file can be found at http://www.hpe.com/support/msa2050.

1. Select your product from the HPE Support & Drivers page.

2. Click Download drivers and software.

3. Choose the appropriate Windows operating system.

4. Select Driver - Storage Controller.

5. Click Download to obtain the appropriate USB Driver for your Windows operating system.

Configuration notes 5

Connecting the MSA 2050 array to remote

management hosts

The management host manages systems out-of-band over an Ethernet network.

To connect the MSA 2050 array to a remote management host, connect an RJ-45 Ethernet cable from the

Ethernet network management port on each MSA 2050 controller to a switch that your management host can

access (preferably on the same subnet).

6 Connecting the MSA 2050 array to remote management hosts

Connecting the MSA 2050 array to expansion

disk enclosures

To connect the MSA 2050 array to expansion disk enclosures, connect a Mini-SAS to Mini-SAS cable from

the SAS expansion port on each MSA 2050 controller to an I/O module in the disk enclosure. Cabling varies,

depending on which of the two supported cabling schemes you use:

• Fault-tolerant cabling

• Straight-through cabling

For more information about these cabling schemes, see

For more information about your MSA 2050, see the HPE MSA 2050 Best Practices guide, available on the

HPE website http://www.hpe.com/support/msa2050.

Supported expansion disk enclosures

The MSA 2050 supports the following disk enclosures:

Disk enclosure model Description

HPE MSA 2040 LFF Disk Enclosure 12-disk LFF enclosure

HPE D2700 Disk Enclosure (supported in MSA

1040/2040 upgrade scenarios only)

25-disk SFF enclosure

HPE MSA 2050 SFF Disk Enclosure 24-disk SFF enclosure

HPE MSA 2050 LFF Disk Enclosure 12-disk LFF enclosure

NOTE:

For more information on D2700 disk enclosure connectivity, see the HPE MSA 2040 Cable

Configuration Guide. Support for D2700 is only available for MSA 1040/2040 upgrades.

Disk enclosure connection guidelines

• Expansion disk enclosures can be connected to an operational MSA 2050 array.

• Use only supported cables. For more information, see the HPE MSA 2050 QuickSpecs, available on the

HPE website: http://www.hpe.com/support/msa2050.

• Mini-SAS to Mini-SAS 0.5 m (1.64 ft) cables are provided with the MSA 2050, and D2700 disk enclosures

(one for each I/O module).

• The maximum length cable supported for connecting disk enclosures is 2 m (6.56 ft).

• Cables longer than those supplied with the disk enclosure must be purchased separately. For a list of

cables available from HPE, see the HPE MSA 2050 QuickSpecs.

• Eight enclosures maximum (including the array enclosure) are supported.

Fault-tolerant and straight-through disk enclosure cabling

MSA 2050 firmware supports both fault-tolerant and straight-through SAS cabling.

Fault-tolerant cabling allows any disk enclosure to fail or be removed while maintaining access to other

enclosures. When connecting multiple disk enclosures, use fault-tolerant cabling to ensure the highest level of

fault tolerance.

Connecting the MSA 2050 array to expansion disk enclosures 7

Straight-through cabling does not provide the same level of fault-tolerance as fault-tolerant cabling. Straight-

through cabling does provide some performance benefits, as well as ensuring that all disks are visible to the

array.

Fault-tolerant cabling example

The following figure shows an MSA 2050 array connected to two MSA 2050 disk enclosures using fault-

tolerant cabling.

I/O modules A on the disk enclosures are shaded blue. I/O modules B on the disk enclosures are shaded

orange. Fault-tolerant cabling requires that you connect controller A to I/O module A of the first disk enclosure

and cascade this connection on to I/O module A of the last disk enclosure cables (shown in blue). Likewise,

you must connect controller B to I/O module B of the last disk enclosure and cascade this connection on to

I/O module B of the first disk enclosure cables (shown in orange).

3. MSA 2050 disk enclosure

Straight-through cabling example

The following figure shows a MSA 2050 array connected to two MSA 2050 disk enclosures using straight-

through cabling.

Straight-through cabling requires that you connect MSA 2050 controller A to I/O module A of the first disk

enclosure which is in turn connected to I/O module A of the last disk enclosure cables (shown in blue). MSA

2050 controller B is connected to I/O module B of the first disk enclosure which is in turn connected to I/O

module B of the last disk enclosure cables (shown in orange).

3. MSA 2050 disk enclosure

IMPORTANT:

Fault-tolerant cabling provides the highest level of fault-tolerance protection for the array. Using straight-

through cabling can sometimes provide increased performance in the array. However, straight-through

cabling also increases the risk of losing access to one or more enclosures if an enclosure fails or is

removed.

Single disk enclosure configurations

The following figure shows a MSA 2050 array connected to a MSA 2050 disk enclosure.

Mixed-connect disk enclosure configurations

The following illustration shows an example of expanding storage from an array enclosure to multiple disk

enclosures of different models.

Single disk enclosure configurations 9

Connecting an MSA 2050/D2700 mixed-connect configuration

The following figure shows a dual-controller array connected to MSA 2050 and D2700 disk enclosures. There

are no restrictions to the order of enclosures when adding MSA 2050 disk enclosures and D2700 disk

enclosures.

1. MSA 2050 array controller

2. MSA 2050 disk enclosure

3. D2700 disk enclosure

Example of the maximum number of enclosures

The following figure shows an example of an array configuration that displays the maximum number of

enclosures that are allowed in an array configuration. The maximum number of enclosures allowed, including

the controller enclosure, is eight.

An array is connected to seven disk enclosures. Each disk enclosure contains 12 drives, and the LFF

controller enclosure contains 12 drives. Combined, the total number of drives is 96 LFF drives. No additional

enclosures can be connected, because the maximum of eight enclosures has already been reached.

NOTE:

When connecting more than two disk enclosures, you may be required to purchase additional 1 m

cables or 2 m cables. Spanning six or seven enclosures requires a 2 m Mini-SAS cable to enable the

proper bend radius.
