Disk Storage
• Newer technologies such as Native FibreChannel and
faster disk drives help greatly in this area.
• Disk array subsystems such as the XP128 improve
processing times for both serial read access and write
access through the use of their cache.
• Larger capacity disk drives may degrade performance in
an OLTP environment, because many small random disk
I/Os are competing for the same spindle.
