IDC storage systems research manager Liz Conner said: "On the heels of a busy end-of-year spending cycle, the enterprise storage system market reverted to a familiar trend.
"Spending on server-based storage was up, spending on traditional external arrays continues to decline, while the nature of hyperscale business leads it to fluctuate heavily with that market segment seeing a heavy decline in 1Q16."
