You are required to support your Oracle RAC configuration using ASM and RAID technology. You
plan to discuss the storage configuration with the storage technology team. They have proposed a
configuration as shown in the exhibit with a separate set of LUNs for the data disk group and the
flash recovery area disk group and a 500 KB stripe size in line with other non-Oracle LUNs. The
Data disk group has four250G LUNs and the FRA disk group has four500G LUNS, both of which
are mirrored.
A.
Index Range Scans would cause I/O to many different physical disks.
B.
The LUNs are not aligned with ASM Allocation Units, which may lead to I/O bottlenecks.
C.
Retention policies that require backups to be kept for long time periods may cause wasted
space due to large allocation units.
D.
I/O to the flash recovery area disk group for backups may cause performance issues when full
table scans are occurring during batch workloads.
