Release Notes

Optimize an SC Series array for an Oracle data warehouse
9 Optimizing Dell EMC SC Series Storage for Oracle OLAP Processing | 2009-M-BP-O
Redundant ports and paths, and HA fault domains
3.2 Direct attach with front-end SAS
For SC Series models that support using front-end SAS connectivity to the servers, configure multiple SAS
connections between each server and the array to provide path redundancy. Multipath software should be
configured on each server to provide automatic path failover and I/O load balancing. Sharing an SC Series
volume through front-end SAS on multiple servers for an Oracle RAC configuration is not supported. For
shared storage configuration in an Oracle RAC deployment, use an FC or iSCSI SAN to provide shared
storage between the RAC cluster nodes.
3.3 Storage layout for an Oracle database
Figure 2 depicts an Oracle RAC database model configured on a SC Series array and managed by Oracle
ASM. While the configuration will vary based on each environment’s unique requirements, the guiding
principles remain similar.
