Hi Bruce,

Welcome to the growing ranks of companies who've decided to create a new
open source high-availability project!

In the Linux community, we seem to have an embarassment of riches when it
comes to HA software.

As you are aware, there is an effort to create a framework of common APIs
and infrastructure for cluster systems and cluster-aware apps.  It covers HA
and HPC clustering, and is intended to encourage sharing of components, and
creation of common interfaces for cluster-aware apps in order to maximize
the benefits of the open source development model, and to create a little
sanity for developers who wish to write cluster-aware apps for Linux and
other environments supported by the Cluster Framework project.  The cluster
framework project will support (at least) Linux, OpenBSD, Solaris, FreeBSD. 
It will probably also support other OSes (such as Tru64 UNIX), depending on
community interest.

It sounds like there is an excellent match between your desires and those of
the cluster framework project. There is a need for different implementations
of cluster components to meet the diverse needs of cluster users.  I'm
confident that your COMPAQ CI for Linux system would make an excellent
addition to the list of cluster components available with the framework.

As a note, it is not necessary for any given cluster component (like the
COMPAQ CI for Linux (CCIL?)) to be available for every platform.  Since the
APIs are common, applications need not be aware of the differences.

There is an work-in-progress paper on the Cluster Framework available on
http://linux-ha.org/framework/

Congratulations and Welcome!

Compaq launches Open SSI Cluster Projects

[bruce]

Compaq has launched two open source technology projects
under the GPL license.  They are briefly described below 
and can be found through www.opensource.compaq.com.

We are actively looking for technology partners, 
contributors, consultants and general kibitzers to
participate via the email lists set up for each project.
Those that just want to monitor the projects are welcome
as well.

Cluster Infrastructure for Linux (CI)
  The goal of this project is to develop a common 
infrastructure for many if not all forms of Linux 
clustering by extending the Cluster Membership and 
Inter-node Communication Subsystems from Compaq's 
NonStop Clusters for Unixware code base.  This project 
also provides the basis for the Open SSI Clusters for 
Linux project.  
   A developers download is available via
www.opensource.compaq.com for Intel-32, along 
with build, boot, hook, interface and api documentation.
We will put the CVS repository on the web when we can.
A port to the alpha chip has already succeeded and 
patches for that are available.

Open Single System Image (SSI) Clusters for Linux Project
   The Open SSI project leverages both Compaq's NonStop
Clusters for Unixware technology and other open source
technology to provide a full, highly available SSI
environment for Linux.  Goals for SSI Clusters include
availability, scalability and manageability, built from
standard servers.  Technology pieces will include:
membership, single root and single init, cluster filesystems
and DLM, single process space and process migration, load
leveling, availability monitors and failover, single namespace  
and shared access for all forms of IPC, devices and networking, 
and a single management space.  The SSI project will leverage 
the Cluster Infrastructure for Linux project.
   Source beyond the CI base is not yet available.  We are
aiming for a developers release of much of functionality in
July.  In the meantime there is a presentation on SSI
Clustering on the web. An initial list of component requirements 
will soon be posted for discussion and refinement.
Join the mail alias via www.opensource.compaq.com
to stay updated.
