the bladeservers I've seen, the bladechassis has a pair of managed 
ethernet switch modules in it, this is where all your network ports 
terminate.   the ILO stuff is just for remote console, NOT for your main 
networking.

those processors in those g3 blades are virtually the same as a pair of 
P4, each blade has 1 or 2 of one of these...

     Dual-Core Intel Xeon processor 2.8 GHZ/800MHz - 4MB
     Single-Core Intel Xeon processor 3.8 GHz/800MHz - 2MB
     Single-Core Intel Xeon processor 3.4 GHz/800MHz - 2MB
     Single-Core Intel Xeon processor 3.2 GHz/800MHz - 2MB
     Single-Core Intel Xeon processor 3.0 GHz/800MHz - 2MB (Low Voltage)
     Single-Core Intel Xeon processor 3.6 GHz/800MHz - 1MB
     Single-Core Intel Xeon processor 3.4 GHz/800MHz - 1MB
     Single-Core Intel Xeon processor 3.2 GHz/800MHz - 1MB
     Single-Core Intel Xeon processor 2.8 GHz - 1MB (Low-Voltage)

a modern Intel 'Core' processor has 2-3 times the bang per Ghz per 
core.   Those old Xeon's will NOT support 64bit virtualization. They use 
buffered DDR2 ECC dram, with a max of 8GB per blade.  The mezzenaine 
board are NOT PCI-E, they are proprietary, and they support HP 
361426-B21 2Gbps Fiberchannel Host Bus Adapters.
