1.1.7. IBM BladeCenter JS12
The JS12 Power blade is a 2-core blade server based on the POWER6™ processor. Its
hardware is very similar to that of the JS22, with several important differences:
•
There is a single POWER6 socket with 2 processor cores
•
The processor cores operate at 3.8 GHz, instead of the JS22’s 4 GHz
•
Two integrated SAS drives are supported on the blade
•
Four additional memory DIMM slots are supported, for a total of eight slots
The JS12 includes the same SP, embedded Gigabit Ethernet (IVE) ports, CFFv and CFFh I/O
expansion slots, and embedded SAS and USB controllers. The JS12 is capable of supporting
twice the number of memory DIMMs because of the new, shorter DIMM design, which allows the
DIMMs to be plugged in vertically. IBM i on the JS12 is supported in BladeCenter H and
BladeCenter S. The following picture shows the JS12, identifying the major components:
