Removing disk bottlenecks
Once a disk bottleneck has been detected, some of the actions that can be taken are the
following:
Use faster disks: 15,000 rpm arrays instead of 10,000 rpm arrays on the DS6000. This will
mean migrating the data to another RANK when incorporating the new disks.
Offload processing to another system in the network (either users, applications, or
services).
Add more RAM. Adding memory will increase system memory disk cache, which in effect
improves disk response times.
Spread the I/O activity across the DS6000 arrays (logs, page file, etc.).
Since the DS6000 arrays can be RAID 5 and RAID 10, swap RAID arrays from one to the
other and take a new set of measurements. F ...
