Apple Mac OS X Server

Many quad-core processors are composed of two separate dies, which means some cached data has to travel outside the processor to get from core to core. That’s an inefficient way to access information. Enter the Quad-Core Intel Xeon “Nehalem” processor. Its single-die, 64-bit architecture makes 8MB of fully shared L3 cache readily available to each of the four processor cores. The result is fast access to cache data, reduced traffic between processors, and greater application performance. Combine that with the other technological advances and you get an Xserve that’s up to 2x faster than the previous generation.¹

Mac OS X Server is the operating system of Xserve computers, rack mounted server computers designed by Apple. Also, it is optionally preinstalled on the Mac mini and Mac Pro ideal for smaller businesses.
