I’ve just read at Ilya Voronin’s blog (blog.curthread.org), that for all the Sun Cluster fans, today is definitely a lucky day, because the new version of Sun Cluster – 3.2 – is already available for download.
By the way, looks like from this version on the clustering solution from Sun is called Solaris Cluster, and includes the following components:
- Sun Cluster
- Sun Cluster Geographic Edition
- Sun Cluster Agents
To my shame and regret, I haven’t got a chance to acquire any useful experience with Sun Cluster. In my company I’m working with Veritas Cluster Server, because it’s a historical thing. But I have some theoretical knowledge of Sun Cluster, and would really like to give it a try some day.
Anyway. Here are just some of the Sun Cluster 3.2 features:
New command line interface
In new Sun Cluster version, you have separate commands for each type of cluster object, and all of them try to have similar names for command line options where possible. Alsom, both short and long names for each option are supported.
Sun Cluster is now tightly integrated with SMF, and easily supports controlling SMF-managed services as Sun Cluster resources.
Sun Cluster Quorum Server
For any scenarios requiring quorum, you no longer have to use shared storage. Sun Cluster supports using a separate Solaris server running quorum-server module. All the atomic reservations will be done over TCP/IP.
Such an approach allows you to reduce the time needed for failing over from one cluster node to another.
Extended Solaris Zones support
Sun Cluster supports now a plethora of services running within non-global zones.
Starting from this Sun Cluster version, ZFS is fully supported as a local highly available filesystem (HA FS).
Multi-Terabyte Disk and EFI (Extensible Firmware Interface) labels
A quite traditional update for many other packages – full support of disks with capacity over 1Tb and new EFI disk labels.
Better support of Veritas products
In particular, components of Veritas Veritas Storage Foundation 5.0 for SPARC are supported, as well as VxVM 4.1 for x86/x64 (in case you didn’t know, Veritas products of these versions are already Solaris 10 aware).
Now you can use Live Upgrade to update your OS with Sun Cluster on top ot if. From documentation I can see that Live Upgrade supports SVM only at the moment, not VxVM.
You can have all the cluster management commands logged now – this is good for both diagnostics and for reproduction of your cluster environment in a new configuration.
