Total worldwide enterprise storage systems revenue grew 2.8% year over year to $9.1bn during the third quarter of 2015, according to the International Data Corporation (IDC ) Worldwide Quarterly Disk Storage Systems Tracker.
EMC managed to retain its position as the number one storage provider, with an 18.4% share of the market; however, it saw an 8% decline in revenue year over year.
In fact, the only top tier vendor to buck the shrinking trend was HP, which saw a 16% revenue growth year over year, prompting its market share to climb to 16.3%, a hair's breadth away from the market leader.
Dell held relatively stable, with a 9.9% share of the market, just 1.6% down on the year ago period.
NetApp followed with 7.1% and IBM's revenues fell a massive 32.5% following the sale of its x86 business. Big Blue now has just a 6.4% share of the market.
Hyperscale infrastructure and server-based storage were the primary spending drivers, with revenue growth strongest amongst original design manufacturers (ODMs) selling directly to hyperscale datacentres. Sales of server-based storage were up 9.9% during the quarter and accounted for $2.1bn in revenue, while hyperscale sales were up 23.4% year over year to $1.3bn.
External storage systems remained the largest market, with $5.8bn in sales, but this represented a decline of 3.1% year over year.
Looking at external disk storage systems alone, EMC - once again - was the largest supplier during the quarter with a 29.1% share of revenues. NetApp and HP finished the quarter in a ‘statistical tie’ for second place with 11.3% and 10.4% share of revenues respectively. IBM held a 9.3% share, while Hitachi a 7.8% share of the market.
"The enterprise storage market continued to follow a consistent trend in the third quarter of 2015," said Liz Conner, research manager at IDC Storage Systems. "Spending on traditional external arrays declined during the quarter as infrastructure refresh, coupled with the demand for software-defined storage and cloud-based storage, drove investments more heavily in server-based storage and hyperscale infrastructure."
All Flash Arrays sales were still in the minor leagues compared to traditional storage and Hybrid Flash Arrays, with just $626.2m in revenue, but this represented very healthy growth of 60.8% year over year.
