Taxonomy Notes

IDC defines an Enterprise Storage System as a set of storage elements, including controllers, cables, and (in some instances) host bus adapters, associated with three or more disks. A system may be located outside of or within a server cabinet and the average cost of the disk storage systems does not include infrastructure storage hardware (i.e. switches) and non-bundled storage software.

The information in this quantitative study is based on a branded view of the enterprise storage systems sale. Revenue associated with the products to the end user is attributed to the seller (brand) of the product, not the manufacturer. Original equipment manufacturer (OEM) sales are not included in this study.

IDC's is a quantitative tool for analyzing the global disk storage market on a quarterly basis. The Tracker includes quarterly shipments and revenues (both customer and factory), Terabytes, $/Gigabyte, Gigabyte/Unit, and Average Selling Value. Each criteria can be segmented by location, installation base, operating system, company, family, model, and region.

The IDC Worldwide Quarterly Enterprise Storage Systems Tracker is part of the Worldwide Quarterly Enterprise Infrastructure Tracker, which provides a holistic total addressable market view of the five key enabling infrastructure technologies for the datacenter (servers, external enterprise storage systems, purpose-built appliances: HCI and PBBA, and datacenter switches).
