RAID controller modules
The S2200 supports single and dual controller configurations. Standard models of the S2200 ship with one
or two RAID controller modules (for more information, see Table 2). Single-controller models can be
upgraded to dual-controller models non-disruptively.
The following types of RAID controller modules are available:
S2200 SAS RAID Controllers
S2200 FC and iSCSI RAID Controllers
S2200 SAS RAID Controllers provide direct SAS attachment for up to two hosts with a supported SAS HBA
installed. Each S2200 SAS Controller has two 6/12 Gb SAS ports with Mini-SAS HD (SFF-8644) connectors.
S2200 FC and iSCSI RAID Controllers provide SAN based iSCSI or FC connectivity to the hosts with a
supported software initiator or HBA installed. Each S2200 FC and iSCSI Controller has a built-in CNC,
which has two SFP/SFP+ ports.
The CNC supports the following storage connectivity protocols, depending on the SFP/SFP+ transceiver
installed or DAC cables attached:
1 Gb iSCSI with 1 GbE RJ-45 SFP optical modules
1/10 Gb iSCSI with 10 GbE SW SFP+ optical modules with LC connectors
10 Gb iSCSI with 10 GbE SFP+ DAC cables
4/8 Gb Fibre Channel with 8 Gb FC SW SFP+ optical modules with LC connectors
Notes:
Both ports on the CNC on the S2200 FC and iSCSI RAID Controller must have the same connectivity
type (the same type of SFP/SFP+ modules or DAC cables).
For dual-controller configurations, both RAID controllers in the system must be of the same type and
they must have matching port configurations (that is, the ports on both S2200 RAID controllers must
have SFP/SFP+ modules of the same type).
Both SAS controllers and FC and iSCSI controllers have one 6 Gb SAS x4 expansion port (Mini-SAS SFF-
8088 connector) for the attachment of the E1012 and E1024 expansion enclosures.
