2.8 Internal Storage
Serial-attached SCSI (SAS) drives the Power 750 and Power 760 internal disk subsystem.
SAS provides enhancements over parallel SCSI with its point-to-point high frequency
connections. SAS physical links are a set of four wires used as two differential signal pairs.
One differential signal transmits in one direction. The other differential signal transmits in the
opposite direction. Data can be transmitted in both directions simultaneously.
The Power 750 and Power 760 have an extremely flexible and powerful backplane for
supporting hard disk drives (HDD) or solid-state drives (SSD). The six small form factor (SFF)
bays can be configured in three ways to match your business needs. Two integrated SAS
controllers can be optionally augmented with a 175 MB Cache RAID - Dual IOA Enablement
Card (Figure 2-13 on page 76). These two controllers provide redundancy and additional
flexibility. The optional 175 MB Cache RAID - Dual IOA Enablement Card enables dual
175 MB write cache and provides dual batteries for protection of that write cache.
There are two PCIe integrated SAS controllers under the POWER7 I/O chip and also the SAS
controller that is directly connected to the DVD media bay (Figure 2-13 on page 76).
Power 750 and Power 760 supports various internal storage configurations:
򐂰 Dual split backplane mode: The backplane is configured as two sets of three bays (3/3).
򐂰 Triple split backplane mode: The backplane is configured as three sets of two bays (2/2/2).
򐂰 Dual storage IOA configuration using internal disk drives (Dual RAID of internal drives
only): The backplane is configured as one set of six bays.
򐂰 Dual storage IOA configuration using internal disk drives and external enclosure (dual
RAID of internal drives and external drives).
Configuration options can vary depending on the controller options and the operating system
that is selected. The controllers for the dual split backplane configurations are always the two
embedded controllers. But if the triple split backplane configuration is used, the two integrated
SAS controllers run the first two sets of bays and require a SAS adapter (FC 5901) located in
