HP Serviceguard Extension for RAC (SGeRAC) amplifies 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.

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. 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 the HP Virtual Server Environment, you can also now maintain service-level objectives during planned and unplanned downtime. 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 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.
