1.6.2 SAS I/O modules
SAS I/O modules provide affordable storage connectivity for BladeCenter chassis using SAS
technology to create simple fabric for external shared or non-shared storage attachments. A
SAS module can also perform RAID controller functions inside the BladeCenter S chassis for
HDDs installed into Disk Storage Module (DSM) and external EXP3000 expansions. The
SAS RAID Controller Module and DSMs in a BladeCenter S provides RAID 0, 1, 5, and 10
support
In the PS700, PS701, and PS702 blades, the 3 Gb SAS Passthrough Expansion Card (CIOv)
is required for external SAS connectivity. The SAS expansion card requires SAS I/O modules
in switch bays 3 and 4 of all supported BladeCenters.
Table 1-11 lists the SAS I/O modules and support matrix.
Table 1-11 SAS I/O modules supported by the SAS pass through card
1.6.3 Fibre Channel switch and pass-thru modules
Fibre Channel I/O modules are available from several manufacturers. These I/O modules can
provide full SAN fabric support up to 8 Gb.
The following 4 Gb and 8 Gb Fibre Channel cards are CIOv form factor and require a Fibre
Channel switch or Intelligent Pass Through module in switch bays 3 and 4 of all supported
BladeCenters. The CIOv expansion cards are as follows:
Emulex 8 Gb Fibre Channel Expansion Card (CIOv)
QLogic 4 Gb Fibre Channel Expansion Card (CIOv)
QLogic 8 Gb Fibre Channel Expansion Card (CIOv)
Additional 4 Gb and 8 Gb Fibre Channel ports are also available in the CFFh form factor
expansion cards. These cards require the use of the MSIM in a BladeCenter H or a MSIM-HT in a
BladeCenter HT plus Fibre Channel I/O modules. The CFFh Fibre Channel cards are as follows:
QLogic Ethernet and 4 Gb Fibre Channel Expansion Card (CFFh)
QLogic 8 Gb Fibre Channel Expansion Card (CFFh)
A list of available Fibre Channel I/O modules that support the CIOv and CFFh expansion
cards is shown in Table 1-12. Not all modules are supported in every configuration of
BladeCenter. Complete compatibility matrixes are available on the following Web pages:
