– Connection Blade Infiniband Switch 40 Gb 18/18
– 18 internal 40-Gbit Infiniband ports to the server blades
– 18 external 40-Gbit Infiniband connections through QSFP modules
I Infiniband connection blades can only be used in the slots CB 3/4,
see figure "Connection blade slots" on page 108. They only support
server blades that are fitted with an Infiniband mezzanine card.
The connection blades support hot-swapping. By installing two connection
blades in two adjacent slots (not possible with Infiniband connection blades),
you can provide redundant network connections for the server blades (for
details, see section "Connection blades" on page 88).
Management blade
The system unit has slots for two redundant, hot-swap management blades with
an integrated management solution for complete remote administration of the
system. The base configuration of the system unit contains one management
blade (for details, see section "Management blades" on page 118).
Power supply
The system unit has four installation bays for hot-plug power supply units which
automatically set themselves to a voltage in the range of 100 - 240 V. The base
configuration includes one power supply unit. As an option, you can set up a
redundant power supply with up to three additional power supply units. If a
power supply unit fails, the redundant configuration assures continued
operation. The defective power supply unit can be replaced during operation
(for further details see section "Hot-plug power supply units" on page 119).
