3.2.1 System p hardware overview
The IBM System p servers offer a range of systems, from entry level to enterprise class. The high-end
systems offer support for gigabytes of memory, large RAID configurations of SCSI and fiber channel disks,
and options for high-speed networking. The IBM System p servers are equipped with a real-time hardware
clock. The clock is powered by a small battery, and continues to tick even when the system is switched off.
The real-time clock maintains reliable time for the system. For the specification of each of the System p
servers, refer to the corresponding data sheets on the System p literature website:
