SP I/O module types

Many I/O module types are supported by the storage processor.

Refer to Platform Overview for a details on the supported types and the system limits of storage processor I/O modules.

• Four-port 12-Gb/s SAS I/O module -- where supported, provides four mini-HD SAS ports (x16 lane) of 12Gb SAS expansion for connecting additional DAEs. This I/O module also supports controller based encryption. Labeled 12Gb SAS v1.
• Four-port 16-Gb/s Fibre Channel I/O module -- provides Fibre Channel connectivity as listed below. Labeled 16Gb Fibre v3.
  • Four ports auto-negotiating to 4/8/16Gbps. Uses optical SFP+ and OM2/OM3 cabling to connect directly to a host HBA or FC switch.
  • One FC port negotiating to 16Gbps, which can be configured for synchronous replication between two Unity systems, either directly connected or connected through a switch. Uses optical SFP+ and SM or MM cabling to provide synchronous replication. The three remaining ports auto-negotiate to 4/8/16 Gbps, and use optical SFP+ and OM2/OM3 cabling to connect directly to a HBA or FC switch.
• Four-port 10-Gb/s optical I/O module -- provides four SFP+ optical or Active/Passive TwinAx 10GbE IP/iSCSI ports for connections to an Ethernet switch. Supports both IP(file) and iSCSI (Block) on the same I/O module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10 GbE v5.
• Four-port 10GBASE-T I/O module -- provides four copper 10GBASE-T RJ45 Ethernet ports for copper connections to an Ethernet switch. Supports both IP (file) and iSCSI (Block) on the same IO module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10GbE BaseT v2.
• Four-port 1GBASE-T I/O module -- provides four 1000BASE-T RJ-45 copper ports for Cat 5/6-cabling connections to an Ethernet switch. Supports both IP (file) and iSCSI (Block) on the same I/O module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 1 GbE BaseT v3.
• Two-port 10Gb/s optical I/O module -- provides two SFP+ optical or Active/Passive TwinAx 10GbE ports for connections to an Ethernet switch. Supports both IP (file) and full iSCSI Offload engine (Block) on the same IO module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10 GbE V6.
