Configuring the IBM ESS™ for Oracle® OLTP Applications
This paper illustrates the “striping and spreading” technique used to achieve highly balanced I/O activity
across the entire ESS subsystem, thereby optimizing overall I/O performance.
This technique requires minimal knowledge of the specific application(s) to be deployed or their underlying I/O characteristics
and it reduces or eliminates the need for manual data file placement or ongoing I/O performance tuning.
The technique simultaneously employs two separate but complementary I/O balancing strategies.
The first strategy is using the hardware RAID-5 and/or RAID-10 “striping” technology within the ESS subsystem.
The second strategy is using the AIX Logical Volume Manager (LVM) to physically partition data files across multiple ESS arrays,
thereby “spreading” I/O activity across all the arrays in the ESS subsystem.
