HP Serviceguard Extension for RAC (SGeRAC):
- Extends HP Serviceguard failover cluster capabilities to Oracle RAC environments
- Enhanced cluster availability and faster failure detection times
- Enhanced Network link availability by leveraging Serviceguard network monitoring and failover capabilities
- More robust data integrity through HP volume managers
- Rich integration with Disaster Recovery Solutions including three data center architectures
Cluster Wide Device File Names. Leverage the Serviceguard cluster wide device name feature to access the same disk by the same name from all nodes in a cluster to save on the time and effort required for storage set up for Oracle RAC in a SGeRAC environment.
Rolling upgrades using DRD cloning. Minimise planned downtime by using Dynamic Root Disk (DRD) in HP-UX 11iv3. Rolling upgrades using DRD is like a rolling upgrade, but it is even less disruptive because each node is down for a shorter time. It is also safe – in case something goes wrong during the upgrade, you can roll back to the original (pre-upgrade) state by rebooting from the original disk.
Serviceguard Extension for RAC ensures that you do not have a single point of failure within the entire Oracle RAC cluster. Not only that, the unique architecture of SGeRAC leverages the full aggregate processing power of up to 16 nodes to access the database. This can increase the overall throughput for query-intensive applications, applications that generate random reads and writes to very large databases, and applications that access separate partitions of the database.
SGeRAC even provides extra protection for database integrity.
The tight integration between SGeRAC and Oracle RAC also enables faster detection and failover, and you can even achieve nearly continuous application availability by implementing a fully disaster tolerant solution.
SGeRAC works together with Oracle Clusterware to provide an improved high-availability solution that can address your concerns over unplanned downtime. It delivers rapid automatic detection and recovery from a wide range of hardware, software, network, and storage errors helps increase the availability of your applications. SGeRAC also provides a superior level of protection by enabling you to withstand multiple node failures. Since
Serviceguard Solutions are part of
HP Insight Dynamics – VSE, you can also now maintain service-level objectives during planned and unplanned downtime.
SGeRAC uses advanced clustering mechanisms and robust volume managers to eliminate data corruption and preserve data integrity. You'll also benefit from data integrity protection among nodes, both inside and outside of the cluster. Flexibility is paramount, so SGeRAC supports four storage management options for Oracle RAC: Cluster file system (CFS), Shared Logical Volume Manager (SLVM), Cluster Volume Manager (CVM) and Automated Storage Management (ASM) on SLVM and raw volumes.
HP Serviceguard Extension for RAC (SGeRAC boosts the availability and simplifies the management of Oracle Real Application Cluster (RAC). SGeRAC allows you to integrate Oracle RAC into a Serviceguard cluster whilst also easily managing the dependency between Oracle Clusterware and Oracle RAC with a full range of storage management options.
Built on the functionality of HP Serviceguard, SGeRAC uses a networked group of
HP Integrity servers to create highly available clusters that support Oracle RAC. Integrated tightly, these two products provide the best features of HP enterprise clusters and Oracle relational database servers. You gain high availability, data integrity, flexibility, and scalability in your Oracle RAC environment—all of which are essential to protect your infrastructure and enhance business uptime.
