In this article we’ll discuss performance considerations for your storage subsystem. When selecting a storage solution you will usually consider the performance, which improves or degrades when considering multiple factors such as cost, reliability, availability and how easy it is to maintain and manage.

There are many factors to consider as storage requests work their way to the actual storage subsystem: cache-management, filesystem architecture, and volume management are all components involved in handling storage requests. They translate application calls into individual access requests, traversing the storage stack and creating a stream of commands that are presented to the disk storage subsystem. The sequence and quantity of those calls can improve or degrade the performance you get out of your storage subsystem.
