Memory Boot Time Deconfiguration
Memory boot time deconfiguration is a function implemented in the service processor firmware to remove a memory segment or DIMM from the system configuration at boot time. The objective is to minimize system failures or data integrity exposure due to faulty memory hardware.
The memory segment or DIMMs that are deconfigured remain offline for subsequent reboots until the faulty memory hardware is replaced. This requires powering off the system. Then, this function gives the user the option to manually deconfigure or
Memory can also be decreased through AIX using the rmss command. This is useful for certain benchmark simulations.
Note
Memory cards should be physically removed only when the power is turned off to the entire system.
System Buses
The system bus is controlled by a highly specialized set of custom chips. One handles addressing and synchronization, the other moves data to and from the processor (the 6XX bus), memory (memory bus), and the I/O (I/O bus). The 6XX bus is a
The 6XX bus is optimized for
The 6XX and memory buses operate at the same speed,
