Worldwide Enterprise External OEM Storage Systems Market Revenue Declined 0.8% During the Second Quarter of 2019, According to IDC

FRAMINGHAM, Mass.--()--According to the International Data Corporation (IDC) Worldwide Quarterly Enterprise Storage Systems Tracker, vendor revenue in the worldwide enterprise external OEM storage systems market decreased 0.8% year over year to $6.3 billion during the second quarter of 2019 (2Q19). Total capacity shipments in the external storage systems market were up 5.2% year over year to 16.3 exabytes during the quarter, while capacity shipments in the total market (including ODMs and server-based storage) declined 4.2% to 107.9 exabytes. Revenue generated by the group of original design manufacturers (ODMs) selling directly to hyperscale datacenters declined 22.9% year over year in 2Q19 to $4.2 billion.

"Second quarter results trended similarly to the first quarter with ODMs continuing to decline against a difficult year-over-year comparison and internal (server-based) storage weighed down by a contraction in the server market," said Sebastian Lagana, research manager, Infrastructure Platforms and Technologies. "While the external OEM segment was pressured by contraction in all-flash arrays, which has long been a growth driver for the segment, we did note end user investment in midrange SAN platforms remained strong, with nearly all OEMs generating growth in that portion of the market."

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 criterion can be segmented by location, installation base, operating system, company, family, model, and region.
