HAFTA beta starts

Astra Network is pleased to announce an open beta of their new High
Availability and Fault Tolerant Architecture (HAFTA) Toolkit. This
toolkit provides both runtime and development tools to aid in developing
highly available and/or fault tolerant systems.

Although the beta is being run as a QNX6 product, with qpr’s and
helpviewer docs, the HAFTA toolkit works in QNX4 as well as Linux and
Solaris.

You can find more information about this product as well as instructions
on how to participate in the beta at http://www.astranetwork.com/hafta.

How does this relate to the QNX High Availability Toolkit?

In some ways it is similiar but there are some very strong differences.

In general you could use a combination of both to achieve certain results.

QNX’s product takes advantage of certain QNX specific features. We took
an approach which is very generic and only depend on POSIX features.
This means we run on anything which is POSIX compliant (in particular we
need the POSIX real time extensions). So at this point we run on QNX4,
QNX6, Linux, Solaris and so far that is all we have tried it on. (Well
actually I tried it on my Mac, but they don’t have the realtime extensions).

We have a generic checkpoint library which allows you to write any
applications with a checkpoint and rollback on failure design. Our
watchdog process, called the overlord is a VM which “runs” platform
independant byte code which describes your system. Some potential
customers have expressed interest in being able to use the same HA
software on multiple platforms. Interest has also been expressed in the
ability to upgrade the byte code without having to replace the
executables.

So I think that answer is that our product and QNX’s are complimentary
rather than competitive.
