I/O bus architecture
PCI-X DDR
Slot requirement
One long, 64 bit, 3.3 V, Peripheral Component Interconnect-X (PCI-X) slot for each adapter.
Adapters are installed in pairs.
Adapter pairs do not require to be in the same enclosure. For higher availability, place adapters
in separate enclosures. See the PCI adapter placement for supported placement rules.
Cables
SAS device attachment requires specific cables that are provided with the subsystem or device
features being attached. Special cabling is required for multi-initiator and high availability
configurations. See Serial attached SCSI cable planning.
Voltage
3.3V
Form factor
Long
Maximum number
For the maximum adapters supported, see the PCI adapter placement topic collection for your
system.
