    Supercapacitor pack To protect RAID controller cache in case of power failure, MSA 2050 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.

  • Page 26: Connecting Hosts

    IMPORTANT: Use the set host-port-mode CLI command to set the host interface protocol for MSA 2050 SAN host ports using qualified SFP options. MSA 2050 SAN models ship with host ports configured for FC. When connecting host ports to iSCSI hosts, you must use the CLI (not the SMU) to specify which ports will use iSCSI. It is best to do this before inserting the iSCSI SFPs into the host ports.
  • Page 27 Each controller module provides four host ports designed for use with an FC SFP supporting data rates up to 16 Gb/s. When configured with FC SFPs, MSA 2050 SAN controller enclosures can also be cabled to support the optionally-licensed Remote Snap replication feature via the FC ports.
  • Page 28: Host Connection Configurations

    Remote Snap replication feature. To connect the MSA 2050 SAN controller to a server or switch—using 10GbE iSCSI SFPs or approved DAC cables in controller ports—select the appropriate qualified 10GbE SFP option (see the QuickSpecs). Such cables are also used for connecting a local storage system to a remote storage system via a switch, to facilitate use of the optional Remote Snap replication feature.
  • Page 29: Connecting Direct Attach Configurations

    Connecting direct attach configurations NOTE: The MSA 2050 SAN diagrams that follow use a single representation for each cabling example. This is due to the fact that the port locations and labeling are identical for each of the three possible interchangeable SFPs supported by the system.
  • Page 30: Connecting Switch Attach Configurations

    The management host directly manages systems out-of-band over an Ethernet network. 1. Connect an RJ-45 Ethernet cable to the network management port on each MSA 2050 controller. 2. Connect the other end of each Ethernet cable to a network that your management host can access (preferably on the same subnet).
  • Page 31: Connecting Two Storage Systems To Replicate Volumes

    If the primary system goes offline, a connected server can access the replicated data from the secondary system. Replication configuration possibilities are many, and can be cabled—in switch attach fashion—to support MSA 2050 SAN systems on the same network, or on different networks. As you consider the physical connections of your system—specifically connections for replication—keep several important points in mind:...
  • Page 32: Cabling For Replication

    Host ports and replication MSA 2050 SAN controller modules can use qualified SFP options of the same type, or they can use a combination of qualified SFP options supporting different interface protocols. If you use a combination of different protocols, then host ports 1 and 2 are set to FC (either both 16 Gb/s or both 8 Gb/s), and host ports 3 and 4 must be set to iSCSI (either both 10GbE or both 1 Gb).

Updating firmware After installing the hardware and powering on the storage system components for the first time, verify that the controller modules, expansion modules, and disk drives are using the current firmware release.
  • Page 37: Connecting To The Controller Cli Port

    Device description The MSA 2050 controllers feature a command-line interface port used to cable directly to the controller and initially set IP addresses, or perform other configuration tasks. This port employs a mini-USB Type B form factor, requiring a cable that is supplied with the controller, and additional support, so that a server or other computer running a Linux or Windows operating system can recognize the controller enclosure as a connected device.
  • Page 38: Preparing A Windows Computer For Cabling To The Cli Port

    IMPORTANT: Although Linux systems do not require installation of a device driver, on some operating system versions, certain parameters must be provided during driver loading to enable recognition of the MSA 2050 controllers. To load the Linux device driver with the correct parameters on these systems, the following command is required: modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1 Optionally, the information can be incorporated into the /etc/modules.conf file.

    Using the CLI port and cable—known issues on Windows When using the CLI port and cable for setting controller IP addresses and other operations, be aware of the following known issues on Microsoft Windows platforms. Problem On Windows operating systems, the USB CLI port may encounter issues preventing the terminal emulator from reconnecting to storage after the Management Controller (MC) restarts or the USB cable is unplugged and reconnected.
  • Page 43: Basic Operation

    Basic operation Verify that you have completed the sequential “Installation Checklist” instructions in Table 1 (page 16). Once you have successfully completed steps 1 through 8 therein, you can access the management interface using your web browser to complete the system setup. Accessing the SMU Upon completing the hardware installation, you can access the web-based management interface—SMU (Storage Management Utility)—from the controller module to monitor and manage the storage system.
  • Page 44: Troubleshooting

    USB CLI port connection MSA 2050 controllers feature a CLI port employing a mini-USB Type B form factor. If you encounter problems communicating with the port after cabling your computer to the USB device, you may need to either download a device driver (Windows), or set appropriate parameters via an operating system command (Linux).
  • Page 45: Performing Basic Steps

    Use the CLI As an alternative to using the SMU, you can run the show system command in the CLI to view the health of the system and its components. If any component has a problem, the system health will be Degraded, Fault, or Unknown, and those components will be listed as Unhealthy Components.

The event logs record all system events.
  • Page 47: Diagnostic Steps

    1. Using the CLI, run the show disk-group-statistics command. The Reads and Writes outputs show the number of these operations that have occurred since the statistic was last reset, or since the controller was restarted. Record the numbers displayed. 2. Run the show disk-group-statistics command a second time. This provides you a specific window of time (the interval between requesting the statistics) to determine if data is being written to or read from the disk group.

    5. Try replacing each power supply module one at a time. 6. Replace the controller modules one at a time. 7. Replace SFPs one at a time (MSA 2050 SAN). Sensor locations The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure.
  • Page 58: Temperature Sensors

    During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling. Temperature sensors Extreme high and low temperatures can cause significant damage if they go unnoticed. When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage. This can be done by warming or cooling the installation location.
