HPE MSA 1050 Storage - Information on Host Connection Configurations

Host connection configurations

The MSA 1050 controller enclosures support up to four Direct-Connect server connections, two per controller module. Connect appropriate cables from the server HBAs to the controller host ports as described below, and shown in the following illustrations.

NOTE: Not all Operating Systems support Direct-Connect. For more information, see the Single Point of Connectivity Knowledge (SPOCK) Storage compatibility matrix Click here to access the "Welcome to SPOCK" for more information .

To connect the MSA 1050 controller to a server or switch - Using FC SFPs in controller ports - Select Fibre Channel (FC) cables supporting 8Gb data rates, that are compatible with the host port SFP connector (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.

To connect the MSA 1050 controller to a server or switch - Using 10 GbE iSCSI SFPs or approved DAC cables in controller ports - Select the appropriate qualified 10 GbE 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.

To connect the MSA 1050 controller to a server or switch - Using the 1Gb SFPs in controller ports - Select the appropriate qualified RJ-45 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.

To connect the MSA 1050 SAS controller supporting HD mini-SAS host interface ports to a server HBA or switch - Using the controller’s SFF-8644 dual HD mini-SAS host ports - Select a qualified HD Mini-SAS cable option (See QuickSpecs). A qualified SFF-8644 to SFF-8644 cable option is used for connecting to a 12 Gb/s host; whereas a qualified SFF-8644 to SFF-8088 cable option is used for connecting to a 6 Gb/s host. Management interfaces distinguish between standard (Dual cable with single connector at each end) and fan-out SAS cables. The fan-out SAS cable is comprised of a single SFF-8644 connector that branches into two cable segments, each of which is terminated by a connector. The terminating connectors attach to the host or switch, and are either both of type SF-8644 or SFF-8088. The storage system must be cabled using either standard cables or fan-out cables; a mixture of cable types is not supported.

NOTE: Before attaching a fan-out cable, make sure to update firmware for the SAS HBA for devices that will be attached to the fan-out cable.

Connecting direct attach configurations

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.

NOTE: The MSA 1050 diagrams that follow use a single representation for FC or iSCSI host interface protocols. This is due to the fact that the port locations and labeling are identical for each of the three possible SFPs supported by the storage system. Within each host connection cabling category, the HD Mini-SAS model is shown beneath the SFP model.

Connecting remote management hosts

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 1050 controller.

  2. Connect the other end of each Ethernet cable to a network that users management host can access (Preferably on the same subnet).

NOTE:
  • Connections to this device must be made with shielded cables - Grounded at both ends - With metallic RFI/EMI connector hoods, in order to maintain compliance with FCC Rules and Regulations.
  • Access via HTTPS and SSH is enabled by default, and access via HTTP and Telnet is disabled by default.
