The SG SMS T2777EB, T8687EB and T8697EB bundles, which include Serviceguard Extension
for RAC (SGeRAC), enable you to:
• Create a standard approach toward application and database management in data centers.
While other clusterware can only work with an Oracle database, SGeRAC incorporates
existing storage management and clustering technologies that provide flexible support for
many types of applications and databases. Administrators can apply existing expertise of
technologies toward this product.
• Set up an infrastructure for Oracle RAC that simplifies database management with the SGeRAC
Toolkit included, while fully integrating with Oracle Clusterware, formerly known as Oracle
Cluster Ready Services (CRS).
• Transition from a local high availability site to a wide-area disaster recovery environment with
primary and secondary sites.
• Back up and recover databases using volume-level and file system-level snapshot technologies.
The SG SMS T2777EB bundle enables full volume-level snapshots for off-host processing that
reduce load on production systems, and file system-level snapshots that involve efficient backup
and rollback processes.
• Prevent data corruption at the storage layer with robust split-brain protection.
• Increase scalability with high throughput and low latency technology for use by Oracle Cache
Fusion.
• Share all types of files, in addition to Oracle database files, across nodes.
