HPE MSA 1050 Storage - Information on Host Interface Protocols

MSA 1050 Storage host interface protocols

The Small Form-factor Pluggable (SFP) (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.

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-Serial Attached SCSI (SAS) interface protocol for host connection. These models do not support Remote Snap replication.

Fibre Channel (FC) protocol

The MSA 1050 controller enclosures support two controller modules using the FC 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.

The MSA 1050 FC controllers support FC 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.

FC ports are used in either of two capacities:

  • To connect two storage systems through a FC 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.

NOTE: 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.

10 GbE 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 10 GbE iSCSI

SFP or approved DAC cable supporting data rates up to 10 Gb/s, using either one-way or mutual Challenge-Handshake Authentication Protocol (CHAP).

NOTE:
  • See the topics about configuring CHAP, and CHAP and replication in the SMU reference guide.
  • 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 10 GbE 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 10 GbE iSCSI hosts directly, or through a switch used for the 10 GbE 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.

1Gb iSCSI protocol

The MSA 1050 controller enclosures support two controller modules using the Internet SCSI interface protocol for host port connection. Each controller module provides two iSCSI host ports configured with an RJ-45 SFP supporting data rates up to 1 Gb/s, using either one-way or mutual CHAP.

NOTE:
  • See the topics about configuring CHAP, and CHAP and replication in the SMU reference guide.
  • 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 1Gb 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 1Gb iSCSI hosts directly, or through a switch used for the 1Gb 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.

12Gb SAS protocol

The MSA 1050 SAS controller enclosures support two controller modules using the Serial Attached Small Computer System Interface (SCSI) protocol for host connection. Each enclosure provides two controller modules using dual SFF-8644 HD Mini-SAS host ports supporting data rates up to 12 Gb/s. HD Mini-SAS host interface ports connect to hosts; they are not used for replication. Host ports can be configured via management interfaces to use standard cables or Fan-Out cables.
