High Availability

Greetings!  While I know that HA clusters aren't really beowulf
machines, what would it take to implement something like the below in
Debian?  Is mosix really the only missing piece?

    Business/Technology Editors
    RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--July 10, 2000--Red Hat,
Inc. (Nasdaq:RHAT), a leader in open source Internet infrastructure
solutions, today announced the Red Hat(TM) High Availability Server 1.0, a
specialized version of the award-winning Red Hat L
    Red Hat High Availability Server is an out-of-the-box clustering
solution that delivers dynamic load balancing, improved fault tolerance and
scalability of TCP/IP
based applications. It lets users combine individual servers into a
cluster, resulting in highly available access to critical network resources
such as data, applications,
network services, and more. If one server in the cluster fails, another
will automatically take over its workload. The Red Hat
to Web servers, ftp servers, mail gateways, firewalls, VPN gateways and
other front-end IP-based applications where virtually uninterrupted service
is required.
    "The Red Hat High Availability Server is optimized specifically for
Internet Service Providers (ISPs) and corporate customers who want to
dramatically reduce
the time needed for implementation," said Paul McNamara, vice president,
products and platforms, Red Hat, Inc. "In today's demanding Internet
environment, server
failure means lost revenue and diminished customer satisfaction. With this
product, we are providing customers with a flexible, affordable, and highly
front-end Internet infrastructure solution. Because the Red Hat High
Availability Server software can be installed on any off-the-shelf
commodity hardware that
supports Linux--it offers service providers and corporate IT departments an
option for increased availability at a significant overall cost savings."
    The product supports heterogeneous network environments, allowing
individual members of the cluster to run Red Hat Linux or virtually any
other OS including
Solaris(R), and Windows NT(R). Because the Red Hat High Availability Server
is an open source product, customers are free from expensive technology
that often occurs with proprietary solutions.
    New Security Features
    The Red Hat High Availability Server has a number of inherent security
features designed specifically for high availability Web front-end
applications. Remote
system access is disabled by default, and unused network services are not
installed or started in the standard installation.
    The Red Hat High Availability Server can be configured in two main
ways. In Failover Services (FOS) mode, the system can be configured as a
two node cold
failover cluster ideally suited for applications where simple, affordable
redundancy is needed such as firewalls, static Web servers, DNS, and mail
servers. In Linux
Virtual Server (LVS) mode, the system can be configured as an n-node
cluster consisting of a two node load balancer, which accepts requests and
directs those
request to one of any number of IP-based servers based on a configurable
traffic management algorithm.
    Red Hat High Availability Server 1.0 Features and Benefits
    -- Easy Installation: The Red Hat High Availability Server is based on
the award winning Red Hat Linux OS. Red Hat's engineers have created a
installation-class that installs only those packages that are needed with
the clustering packages. The Red Hat High Availability Server is installed
for optimal
performance--saving time and hassle.
    -- Higher Performance and Scalability: The Red Hat High Availability
Server supports the scalability that meets the growth demands of today's
highly dynamic IP
environments. The number of cluster nodes is limited only by the hardware
and network used. The product has advanced cluster features that provide
high levels of
performance including an ability to configure servers to bypass the load
balancers when returning traffic back to the client, increasing the overall
performance of the
cluster. Additionally, because individual nodes can be taken off-line
