P ow erPC G5 P roc essor The breakthrough performance of the 64-bit P owerPC G5 is now av ailable to Apple server customers. With 6 4-bit-wide data paths and registers , this revolutionar y pro- cessor can address v ast amounts of main memory , while handling multiple 6 4-bit integer and double-precision floating-poin t math calculations in a singl[...]

V ast amounts of addressable memory The move t o 64-bit processing results in a similarly dramatic leap in the amount of memory suppor ted. A memory address is a special kind of integer , and each address points to one byte in memory . Since memory addresses are computed in 64-bit regis- ters capable of expressing 1 8 billion billion in tegers, the[...]

High-Bandwidth Ser ver Archit ec ture The P owerPC G5 is only part of the Xser ve performance stor y . Xserve G5 features the industry ’ s fastest fron tside bus to keep data moving in and out of the processor , and a superefficient point-t o-point system controller allows data t o move directly between all subsystems. Bandwidth is further enhanc[...]

Gigaher tz F rontside Bus T o harness the power of the G5 processor , a 6 4-bit Double Data Rate (DDR) frontside bus speeds up communication between the P owerPC G5 and the memor y controller . Unlike conventional pr ocessor interfaces, which carr y data in only one direction at a time, this dual-channel frontside bus has tw o 3 2-bit point-to-poin[...]

Support for up to 8GB of RAM Xserve G5 comes standard with 5 1 2MB or 1GB of DDR SDRAM. Main memory is scalable up to 8GB in eight DIMM slots, allowing you t o increase memor y as application and networking requirements increase . More main memor y enables the system to run strenuous processes simultaneously and t o accommodate spikes in demand. En[...]

Dual Gigabit Ethernet ports deliver near-line-rate throughput of up to 980Mb/s per port, alleviating bottlenecks ev en with very large files and expediting mail, web, file , and printer sharing services. T ogether with the multihoming func tion in Mac OS X Ser ver , dual netw ork ports enable Xser ve G5 to ser ve more clien t systems; provide redun[...]

Aff or dable , Scalable Stor age Exponential growth in the creation and distribution of digital con tent is driving the need for high-capacity storage in business and education.
