|Optimizing internal AIX storage
Although SAN technology has taken the limelight when it comes to storage solutions, AIX systems still need to use internal storage. Whether you have small stand-alone servers or use a full system partition with all the resources available pooled together, internal storage is the typical medium for root volume groups and other smaller file system utilization. But when these disks are not planned out well, I/O bottlenecks, inefficient space utilization, and slower performance can occur. Learn how to optimize internal storage and lay things out properly.
