Memory Channel adapters (CCMAB-BA) must be configured in 5-volt PCI slots.
Up to two PCI-to-System Area Network adapters (CCMAB-BA) are supported in a single system.
Two-node clusters can be configured by ordering a CCMAB-BA for each node and one
BN39B-04 or BN39B-10 cable; cable connects directly to CCMAB-BA in each node.
For a two-node cluster that will not need to be rebooted when adding additional members,
order one CCMAB-BA adapter and one BN39B-04 or BN39B-10 cable for each node, and
one CCMHB-AA hub for the cluster.
For three- or four- node clusters, order one CCMAB-BA adapter and one BN39B-04 or
BN39B-10 cable for each node, and one CCMHB-AA hub for the cluster. If two CCMAB-BAs
are configured in each system, a second CCMHB-AA is required.
CCMHB-AA includes four CCMLB-AA line cards and supports up to four nodes; expansion up
to eight system nodes can be achieved by adding up to four CCMLB-AA line cards.
If nodes must be separated by a distance longer than standard copper cables allow the
CCMFB option converts the output of the standard CCMAB controller or CCMLB line card to
single-mode fiber optic cable. The fiber optic connection may be up to 2,000 meters long
between two CCMAB controllers connected in virtual hub mode, or 3,000 meters between a
CCMAB controller and a CCMHB hub. (The connection from the CCMHB hub to a second
system may also be 3,000 meters.) The CCMFB option requires a second PCI slot in the system
from which it draws power only. It is normally connected to the corresponding CCMAB
controller with the short BN39B-01 cable. The CCMFB is also used in the CCMHB hub where it
occupies a slot normally used by the CCMLB line card, limiting expansion to four radial fiber
optic connections.
CCMHB-BA hub expansion box provides additional slots for up to eight fiber optic connections.
Two standard length single-mode fiber optic cables are available (BN34R-10 and BN34R-31);
however, users normally provide this fiber optic connection. Fiber optic connectivity is
completely transparent to the systems using it and has no performance impact.
