Frank,The Sun Cluster 3.2 Beta program has been extended. You can apply for the Beta via this URL: https://feedbackprograms.sun.com/callout/default.html?callid={11B4E37C-D608-433B-AF69-07F6CD714AA1} Sun Cluster 3.2: New FeaturesEase of Use New Sun Cluster Object Oriented Command Set The new SC command line interface includes one command per cluster object type and consistent use of sub-command names and option letters. It also supports short and long command names. The commands output have been greatly improved with better help and error messages as well as more readable status and configuration reporting. In addition some commands include export and import options with use of portable XML-based configuration files allowing replication of portion of, or entire cluster configurations. This new interface is easier to learn and easier to use, thereby limiting human errors during administration of clusters. It also speeds up partial or full configuration cloning. Oracle RAC 10g improved integration and administration Sun Cluster RAC packages installation as well as configuration are now integrated in the Sun Cluster procedures. New RAC specific resource types and properties can be used for finer grained control. Oracle RAC extended manageability leads to easier set-up of Oracle RAC within Sun Cluster as well as improved diagnosability and availability. Agent configuration wizards New GUI-based wizard provides simplified configuration for popular applications via on-line help, automatic discovery of parameter choices and immediate validation. Supported applications include Oracle RAC and HA, NFS, Apache and SAP. The configuration of agents is easier and less error-prone enabling faster set-up of popular solutions. Flexible IP address scheme Sun Cluster now allows a reduced range of IP addresses for its private interconnect. In addition it becomes also possible to customize the IP base address and its range during or after installation. These changes facilitate integration of Sun Cluster environments in existing networks with limited or regulated address spaces.
Availability Cluster support for SMF services Sun Cluster now integrates tightly with Solaris 10 Service Management Facility (SMF) and enables the encapsulation of SMF controlled applications in the Sun Cluster resource management model. Local service-level life-cycle management continues to be operated by SMF while whole resource level cluster-wide failure (node, storage, ...) handling operations are carried out by Sun Cluster. Moving applications from a single node Solaris 10 environment to multi-node Sun Cluster environment enables increased availability while requiring limited-to-no effort. Extended flexibility for fencing protocol This new functionality allows the customization of the default fencing protocol: choices include SCSI 3, SCSI 2 or per-device discovery. This flexibility enables the default usage of SCSI 3, a more recent protocol, for better support for multi-pathing, easier integration with non-Sun storage and shorter recovery times on newer storage while still supporting the SC 3.0/3.1 behavior and SCSI 2 for older devices. Quorum Server A new quorum device option is now available in Sun Cluster: instead of using a shared disk and SCSI reservation protocols, it is now possible to use a Solaris server outside of the cluster to run a quorum server module supporting an atomic reservation protocol over TCP/IP. This enables faster failover time but also lowers deployment costs: it removes the need of a shared quorum disk for any scenario where quorum is required (2-node) or desired. Disk path failure handling Sun Cluster can now be configured to automatically reboot a node if all its path to shared disk have failed. Faster reaction in case of severe disk path failure enables improved availability. HA Storage plus availability improvements HA Storage plus mount points are created automatically in case of mount failure to eliminate failure-to-failover cases thus improving availability of the environment
Flexibility Solaris Container expanded support This allows the combination of the benefits of application containment offered by Solaris containers and the increased availability provided by Sun Cluster. Note: Currently only the following Sun Cluster Agents are supported in Solaris Containers
HA ZFS ZFS is supported as a failover file system in Sun Cluster. ZFS and Sun Cluster offers a best class file system solution combining high availability, data integrity, performance and scalability covering the needs of the most demanding environments. HDS TrueCopy campus cluster Sun Cluster based campus clusters now support HDS TrueCopy controller based replication allowing for automated management of Truecopy configurations. Sun Cluster handles automatically and transparently the switch to the secondary campus site in case of fail-over making this procedure less error-prone and improving the overall availability of the solution. This new remote data replication infrastructure allows Sun Cluster to support new configurations for customers who have been standardizing on specific replication infrastructure like TrueCopy and for places where host based replication is not a viable solution because of distance or application incompatibility. This new combination brings improved availability and less complexity while lowering cost. Sun Cluster can make use of existing TrueCopy customer replication infrastructure limiting the need for additional replication solution. Multi-terabyte disk and EFI label support Sun Cluster configurations can now include disks with capacity over 1TB thanks to the support of the new disk format called EFI. This format is required for multi-terabyte disks but can also be used with smaller capacity disks. This extends the supported Sun Cluster configurations to environments with high-end storage requirements. Extended support for Veritas software components Veritas Volume Manager and File System part of Veritas Storage Foundation 5.0 are now supported on SPARC platforms as well as Veritas Volume Manager 4.1 with Solaris 10 OS on x86/x64 platforms.
Veritas Volume Replicator (VVR) and Veritas Fast Mirror Resynchronisation (FMR), part of Veritas FlashSnap can now be used in Sun Cluster environments on SPARC platforms. In adding support for Veritas replication and synchronisation technology, x86/x64 version and the latest release of Veritas software Sun Cluster provides more choice for customers and allows them to use Sun Cluster in environments where 3rd. party storage management solutions like Veritas Storage Foundation are standards. Quota support Quota management can now be used with HA Storageplus on local UFS file systems for better control of resource consumption. Oracle DataGuard support Customers are now able to operate Oracle Data Guard data replication configurations under Sun Cluster control. Sun Cluster now offers improved usability for Oracle deployments including Data Guard data replication software.
OAMP Dual partition software swap With this new software swap feature the upgrade process is greatly simplified: any component(s) of the software stack along with Sun Cluster can be upgraded in one step: Solaris, Sun Cluster, File Systems and Volume Managers, Applications. This automation lowers the risk induced by human errors during cluster upgrade ,a very complex procedure and minimizes service outage occurring for a classical cluster upgrade . Live upgrade The Live upgrade procedure can now be used with Sun Cluster. This procedures allows to reduce system downtime of a node during upgrade as well as unnecessary reboots therefore lowering the required maintenance window where the service is at risk.
Optional GUI installation Sun Cluster Manager, the Sun Cluster management GUI can be left out during installation. This removes web based access to the cluster to comply with potential security rules. SNMP event MIB Sun Cluster includes a new Sun Cluster SNMP event mechanism as well as a new SNMP MIB. They now allow 3rd. party SNMP management applications to directly register with Sun Cluster and receive timely notifications of cluster events. Fine grained event notification and direct integration with 3rd. party enterprise management framework through standard SNMP support allow proactive monitoring and increase availability.
Command logging Commands can now be logged within Sun Cluster. This ability facilitates diagnostics of cluster failures and provides history of the administration actions for archiving or replication. Workload system resource monitoring Sun Cluster offers new system resources utilization measurement and visualizatio tools including fine grained measurement of consumptions per node, resource, resource group. These new tools provide historical data as well as threshold management and CPU reservation and control. This improved control allows for better management of service level and capacity
Performance Several performance improvements have been introduced in this latest Sun Cluster release.
