Onboard Administrator. On server blades, iLO2 advanced features are enabled by default and
include the following:
• Full remote graphics console access including full keyboard, video, mouse (KVM) access
through a Web browser
• Support for remote virtual media which enables you to mount a local CD or diskette and
serve it to the server blade over the network
1.4.4 Management Processor Console Management Device
Each HP Integrity server blade has a built-in management processor (MP) device that provides
full remote power control and serial console access. You can access the MP device by connecting
a serial terminal or laptop serial port to the local IO cable that is connected to the server blade.
1.4.5 Mezzanine Cards
The mezzanine slots on each server blade provide additional I/O capability. Mezzanine cards
are PCI-Express cards that attach inside the server blade through a special connector and have
no physical I/O ports on them. Card types include Ethernet, fibre channel, or 10 Gigabit Ethernet.
1.4.6 Interconnect Modules
An interconnect module provides the physical I/O for the built-in NICs or the supplemental
mezzanine cards on the server blades. An interconnect module can be either a switch or a pass-thru
module.
A switch provides local switching and minimizes cabling. Switch models that are supported as
interconnect modules include, but are not limited to:
• Nortel GbE2c Gigabit Ethernet switch
• Cisco Catalyst Gigabit Ethernet switch
• HP 4x DDR InfiniBand switch
• Brocade SAN switch
A pass-thru module provides direct connections to the individual ports on each node and does
not provide any local switching.
Bays in the back of each enclosure correspond to specific interfaces on the server blades. Thus,
all I/O devices that correspond to a specific interconnect bay must be the same type.
Interconnect Bay Port Mapping
Connections between the server blades and the interconnect bays are hard wired. Each of the 8
interconnect bays in the back of the enclosure has a connection to each of the 16 server bays in
the front of the enclosure. The built-in NIC or mezzanine card into which the interconnect blade
connects depends on which interconnect bay it is plugged into. Because full-height blades consume
two server bays, they have twice as many connections to each of the interconnect bays.
See the HP BladeSystem Onboard Administrator User Guide for illustrations of interconnect bay
port mapping connections on half- and full-height server blades.
