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. (Note: print this in landscape mode to view the complete page in hardcopy format.)
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):
Server Blade Type		One 24-Port Server Blade InfiniBand Switch per Enclosure (410398-B21)				Two 24-Port InfiniBand Switches per Enclosure (410398-B21)
Single-Density, Full Height		1:1 BW				N/A
Single-Density, Half Height		2:1 BW				1:1 BW
Double-Density, Half Height		N/A				2:1 BW
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 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 of the ServerA and ServerB nodes to communicate (2:1 bandwidth DDR).
