Just wanted to give you all a heads up that Monday morning we here at
Mission Critical Linux will be GPL-ing our cluster software called
Kimberlite. This is a complete high availability failover
infrastructure. Check it out at oss.missioncriticallinux.com.
Some of the key attributes of the implementation:
- Provides high data integrity guarantees, insuring that a service is
only running on a single cluster member at any time.
- Uses commodity hardware.
- Implemented primarily as user space daemons
- Distribution independent
- Extensive end user documentation and design specification
- Shared storage architecture (i.e. SCSI or FibreChannel)
- Quorum based membership algorithm
- I/O fencing by way of remote control power modules (known
affectionately
in this forum as STONITH)
- Targeted at supporting applications such as databases, NFS services,
etc.
We are really psyched to have gotten approval to open up the project to
the open source community. The code provided here is fully
operational. Please check it out, and we look forward to your
participation.
Kimberlite and LVS are very complimentary. Specifically, LVS is great
as the front-end HTTP server tier, but doesn't address the needs of a
high availability storage tier necessary for dynamic content. That's
where Kimberlite comes in.
