Red Hat Enterprise Linux WS
Red Hat Enterprise Linux WS is the technical and design
workstation partner for Enterprise Linux AS and Enterprise Linux ES.
It is ideal for all engineering desktop deployments, including design
workstations, software development environments, and targeted engineering
ISV client applications. When configured as a headless workstation,
Enterprise Linux WS is also ideally suited for use as a compute node
in a high performance computing (HPC) environment.
Red Hat Enterprise Linux WS is fully compatible with other members
of the Red Hat Enterprise Linux product family and provides complementary
technology and services.
Red Hat Enterprise Linux WS provides support for workstation systems
with up to two CPUs. Designed with the client environment in mind,
Red Hat Enterprise Linux WS does not include a number of server applications
found in Red Hat Enterprise Linux AS and Red Hat Enterprise Linux ES.
All products in the Red Hat Enterprise Linux family are based on a
common software core--kernel, libraries, development toolchain, and
utilities. This provides a homogeneous environment ideal for simplifying
multi-system and desktop-to-datacenter configurations. The immediate
benefit: simplified deployment of distributed applications, and a consistent
environment for users and system administrators across the entire family.
