Determining “value” of a data storage system is often an exhaustive and difficult task that is further muddied by vendors’ features and claims versus the realities of your data center needs. When comparing data storage systems, determining value helps you decide which vendors to consider in the evaluation process.
Data storage systems are designed to do three things: read data, write data, and store data. A system’s ability to quickly and efficiently accomplish these functions versus that system’s overall price is its value. Measurements for each of the core data storage functions are readily available as is the purchase price of the system. Using those measurements in a consistent formula allows you to effectively compare the true value of all systems you are considering.
The Xiotech Value Index was designed to establish an industry benchmark for evaluating disparate data storage systems. This formula determines each system’s “Value Index” by taking a holistic view of the system, analyzing its functionality versus its cost. Higher Value Indexs are more desirable.
