IOPS problem  Eric Slack Eric Slack Profile: Eric Slack  In a

clients: storage performance. Most users can tell when they’re
out of capacity, but solving a performance problem is not so
clear-cut. This is due in part to the fact that getting data
into and out of a storage system is arguably as important as how

traffic we’re seeing for a recent article on I/O, “What is I/O,
and why should you care?,” storage performance is a topic users

and writes, or simply “transfer rate” and I/O per second, or
IOPS. The
