Linux 2.6 Review
A primary focus of the v2.6 kernel is large server architectures. Support for up to 64GB RAM in paged mode, the ability to address file systems larger than 2TB, and support for 64 CPUs in x86-based SMP systems brings this kernel and Linux into the more rarified air of truly mission-critical systems. The included support for NUMA (Non-Uniform Memory Access) systems; a next-generation SMP architecture; and PAE (Physical Address Extensions), providing support for up to 64GB of RAM on 32-bit systems, is also new.
