I/O management ensures utilization

I/O management can also ensure utilization. Utilization is highly important for businesses because it ensures that the entire infrastructure a business possesses is being used to its capacity, in an efficient manner. Essentially, I/O management ensures that the business is getting the most out of its infrastructure. While the various elements in a storage network are all specified to carry a certain bandwidth (that is, 4GB Fibre Channel link, 2GB Fibre Channel array port, 10GB Ethernet port, etc.), there are many factors that come into play when determining how many I/O operations the elements can handle.

Sometimes bottlenecks can occur within the various I/O handling layers if they are overloaded. When this happens, I/O path contention areas create visibility issues. In this way, I/O management can add critical insight into performance and availability management, which can then help an administrator configure optimal utilization.

The I/O tools create a combination of data that, when efficiently collected and managed with the right management tool, becomes an invaluable resource to proactively address potential performance problems, reactively troubleshoot the root cause of performance issues, and deploy and maintain an efficient I/O infrastructure.
