Access "Capacity, throughput demands grow unabated"
This article is part of the Vol. 4 No. 11 January 2006 issue of Boosting data storage array performance
Forget 50% annual capacity growth. Shops with unstructured data regularly report data doubling every couple of months, fueling a run on high-capacity storage systems. But it isn't just about capacity. In many cases, the throughput of the system needs to scale as much as the data does. At Movielink LLC, a joint venture among five major Hollywood studios that offers downloadable movies, it's quite possible storage capacity will double--maybe even triple--in the next six months, says Bruce Anderson, VP of Web engineering and operations at the Santa Monica, CA-based firm. An Isilon Systems' IQ customer with two clusters totaling 9TB, Movielink is simultaneously bracing itself for new content deals that will expand the number of titles in its catalog, additional file formats, higher density encoding bit rates and, hopefully, a surge of post-holiday customers.

Pump up array performance
As data wends it ways from hosts, through the fabric and to the array, it encounters many potential bottlenecks. But that also means there are a number of ways to improve storage subsystem performance. The key to the tuning process is a thorough understanding of your application requirements.
