| 1.1 BladeSystem c7000 Enclosure Configurations |
|
| The
following figures and tables describe the half-height and full-height server
blades and their configurations in either an InfiniBand configuration or a
gigabit Ethernet configuration in a c7000 BladeSystem enclosure. |
|
| These figures show the front view and server blade bay numbering
scheme for half-height and full-height server blade configurations: |
|
|
|
|
The following figure and table map the server blade's embedded
NICs and mezzanine port slot assignments for various server blade types
(single-density full-height, single-density half-height, and double-density
half-height server blades) to the HP BladeSystem c7000 enclosure interconnect
module bays.

|
| The following table maps the server blade type and the
InfiniBand switch to its bandwidth in InfiniBand configurations (note that
this table does not apply to gigabit Ethernet configurations): |

| For the 24-port server blade InfiniBand switches, there are 16
downlinks and 8 uplinks on the switches. For single-density, half-height
server blades, there are 16 server blades in the enclosure utilizing all 16
internal ports (2:1 bandwidth DDR). For full-height server blades there are 8
server blades in an enclosure using just 8 of the internal links and using
the 8 uplinks (1:1 bandwidth DDR). For double-density server blades, there
are 16 SserverA and 16 ServerB nodes. Only the ServerA or the ServerB nodes
will connect to a server blade InfiniBand switch, and you will need to have 2
server blade InfiniBand switches installed to allow all of the ServerA and
ServerB nodes to communicate (2:1 bandwidth DDR). |
|
| For the 32-port server blade InfiniBand switches, there are 16
downlinks and 16 uplinks on the switches. For single-density, half-height
server blades, there are 16 blades in the enclosure utilizing all 16 internal
ports (1:1 bandwidth DDR or QDR). For full-height server blades there are 8
server blades in an enclosure using just 8 of the internal links and using
the 8 uplinks (1:1 bandwidth DDR or QDR). For double-density server blades,
there are 16 ServerA and 16 ServerB nodes. Only the ServerA or the ServerB
nodes will connect to a server blade InfiniBand switch, and you will need to
have 2 server blade InfiniBand switches installed to allow all the ServerA
and ServerB nodes to communicate (1:1 bandwidth DDR or QDR). |
