QLogic 10000 Series Realize Significant Performance Gains in Oracle RAC with QLogic FabricCache - Manual

White PaPer
Key Findings
• QLogic ® recommends using the QLogic FabricCache™ 10000 Series adapter in an Oracle ® real application Cluster (raC) database
with Oracle’s automatic Storage Management (aSM) feature enabled and provisioning LUNs as a multiple of the quantity of nodes
in the raC cluster. this configuration ensures distribution of the cache load over the QLogic 10000 Series adapters in the cluster.
• Oracle recommends four LUNs for a disk group and, for best cache optimization, making the LUN quantity a multiple of the nodes.
• each 10000 Series adapter may cache up to 256 LUNs.
• all 10000 Series adapters in the cluster must be zoned to be visible to each other.
• QLogic FabricCache 10000 Series adapters enable:
– OLtP processing to be almost twice the transactions at 56 percent of the response time.
– OLaP processing to be 3.25 times the transactions at 25 percent of the response time.
