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.
–
