Project Colorado: Running Open HA Cluster on OpenSolaris
By tf on Sep 09, 2008
If you have ever asked yourself why Solaris Cluster Express is running on Solaris Express Community Edition and not yet on the OpenSolaris binary distribution, then you might be interested in project Colorado. This project is endorsed by the HA Clusters community group and has as its goal to provide a minimal and extensible binary distribution of Open HA Cluster that runs on the OpenSolaris binary distribution.
As always, the devil is in the details. The following table summarizes some of the reasons why this isn't just a "recompile and run" experience:
|Work Area||Solaris Express Community Edition||OpenSolaris Binary Distribution|
|Packaging System||System V packages||Image Packaging System (IPS)|
|Zones support||native and lx brand type||ipkg brand type|
|KSH version||KSH88, KSH93||KSH93|
|Web-based system management for applications||Sun Java Web Console (webconsole)||not provided|
|Encumbered Solaris code||CDE, Motif, ToolTalk||not contained by design|
|Supported Platforms||SPARC, i386/x64||i386/x64 only (to date)|
|Installer||Supports network (JumpStart), text, and graphical installation||Supports graphical installation only (to date)|
|Preferred Compiler||Studio 11, soon Studio 12||StudioExpress|
You can read here more details about each point listed within the table.
Besides solving the above challenges, we also want to offer some new possibilities within Colorado. You can read the details within the umbrella requirement specification. There are separate requirement specifications to outline specific details for the planned private-interconnect changes, cluster infrastructure changes involving the weaker membership, enhancements to make the proxy file system (PxFS) optional, and changes to use iSCSI with ZFS for non-shared storage configurations.
You can provide feedback on those documents to the ha-clusters-discuss mailing list. There is a review scheduled with the Cluster Architecture Review Committee on 18 September 2008, where you are invited to participate by phone if you are interested.
