Apple Xserve
The Xserve was a server from Apple , which was intended for installation in a 19 ″ rack . It was not sold with the normal Mac OS X operating system , but with Mac OS X Server .
development
The first Xserve was introduced in May 2002. In March 2003, Apple introduced the Xserve Cluster Nodes, which have only a single hard drive and are not equipped with video cards or optical drives. Some of the fastest supercomputers in the world were Xserve clusters. As the highest-ranking system, the installation at Virginia Tech reached seventh place in the TOP500 list of November 2004.
In 2004 the Xserve G5 was introduced, which has one or two PowerPC 970 processors with 2 GHz. For reasons of heat dissipation, only 3 hard drives can be installed in it. The space for the fourth hard drive was required for ventilation. Between January 2005 and August 2006, the dual processor Xserve were shipped with a CPU speed of 2.3 GHz. At the WWDC 2006 in San Francisco on August 7th, 2006 the new Xserve with Intel processors was presented. In October 2006, the Xserve were shipped with an up to 3 GHz quad-core 64-bit "Woodcrest" Xeon processor from Intel. According to Apple, these are up to 5 times faster than the old servers with G5 processors.
The Xserve supports up to three SATA and SAS drives and a maximum internal storage capacity of up to 2.25 TB. In addition, it had two PCI Express slots with 8 lanes and two Gigabit Ethernet connections, which enable simultaneous connection to several networks. As with the Xserve G5, an internal DVD-ROM / CD-RW drive was installed. The 256-bit memory controller with a bandwidth of up to 21.3 GB / sec. supports up to 32 GB DDR2 RAM with 667 MHz.
An Xserve with a redundant power supply unit could be purchased as an option. This is an important criterion for industrial suitability, e.g. B. in the area of process control systems, which must have a very high availability. The Xserve often serves as a metadata controller within an Xsan environment in conjunction with one or more Xserve RAIDs. The Xserve G5 cluster nodes are very often found in render farms for outsourcing and accelerating computing power in the field of video editing, compositing and 3D.
Production of the Xserve ceased on January 31, 2011.
