Total enterprise storage revenue rose 7.2 percent in Q4 2014 to nearly $10.6 billion and 3.6 percent in 2014 to $36.2 billion, said IDC.
Shipments increased 43.7 percent in Q4 2014 to 31.8 exabytes and 43 percent in 2014 to 99.2 exabytes.
All top 5 storage vendors — EMC, HP, Dell, IBM and NetApp — have dropped their storage market share.
Fourth quarter spending on enterprise storage systems was driven by year-end seasonality, demand for midrange systems that incorporate flash capacity, and continued growth of systems designed for hyperscale datacenters.
Disk Storage Systems Market
EMC had 22.2 percent share in the disk storage systems market in Q4 2014, while HP had 13.8 percent. Dell and IBM each accounted for 9 percent of global spending.
Storage systems sales by original design manufacturers (ODMs) selling directly to hyperscale datacenter customers accounted for 12.8 percent of global spending.
External Disk Storage Systems
EMC had 32.9 percent share in the external disk storage systems market. IBM and NetApp generated 11.7 percent and 10.7 percent of total sales, respectively. HP generated 9.6 percent of the revenue.
