Accelerating Database Infrastructure Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache Executive Overview Thousands of companies world-wide use Oracle Real Application Clusters (RAC) running on cost effective server hardware, to run mission-critical applications for their business. Today’s more powerful servers, increased use of virtualization and increased datacenter density allow for large-scale implementations of database applications based on Oracle RAC.
Accelerating Database Infrastructure Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache deliver can be impacted by I/O throughput capacity and transaction latency. Thus, optimization of the I/O capabilities of the database infrastructure can pay big dividends when I/O workloads are high, extending the capabilities of the infrastructure and allowing the hosted databases to deliver maximum performance to business users.
Accelerating Database Infrastructure Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache that not only will all servers caching hot data see higher I/O throughput, but those reads will have been offloaded from the SAN and the storage array, so they will have more resources to devote to processing write operations.
Accelerating Database Infrastructure Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache Scalability. QLogic’s FabricCache adapters deploy caching at the HBA within each server in the RAC cluster. By satisfying many read requests in the server-side cache, FabricCache effectively offloads the SAN and storage array. This leaves more resources available for processing writes, which can mean that write performance improves.
Accelerating Database Infrastructure Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache Implementation downtime Professional Deployment Services Effecting significant change to your IT environment can be a daunting task. Typically, the most effective strategy is to utilize deployment services to quickly and efficiently handle the initial push.
