Sun Cluster 3.2 01/09
Sun announced the availability of Sun Cluster 3.2 1/09. Several interesting features found their way into this release:
- Cluster Configuration Checker
- Data Service for Informix
- Exclusive-IP Zones Support
- Global-Devices Namespace on a lofi Device
- IPsec on the Cluster Interconnect
The cluster interconnect transports a lot of data depending on the configuration, for example due to the PxFS. So it's not unreasonable to encrypt this interconnect. - Optional Fencing
- PostgreSQL WAL Shipping Support
With this feature you can build a cluster without shared storage. You work with synchronized databased via Log Shipping and you switching over to a independent database. So you don't need a SAN to build a database cluster - Quorum Enhancements
- Software Quorum
This one is interesting for devices unable to use SCSI reservations for the quorum. With a software quorum you can use any harddisk you can attach at the cluster nodes - Quorum Monitoring
- New Automated Response to a Change in Quorum Device Status
- Solaris Containers Clusters, or Zone Clusters
- ZFS Root File Systems, Except the Global-Devices Namespace
