IOPS: Changing Needs

Four years have elapsed since our first IOPS survey – What has changed? Since 2012 we have been surveying SysAdmins and other IT professionals to ask how many IOPS they need and what latency they require. Things have changed over the past four years. Everyone understands that SSDs can give them thousands to hundreds of thousands of IOPS (I/Os Per Second), with flash arrays offering numbers in the million-IOPS range, while HDDs only support from tens to hundreds of IOPS. But many applications don’t need the extreme performance of high-end SSDs. In the survey users shared their IOPS needs with us both in 2012, and again in 2016. What has changed? What has remained the same? This presentation examines the need for high IOPS and profiles applications according to these needs.

Learning Objectives

Hear what your peers consider the necessary level of performance in both IOPS and latency for various common enterprise applications
Learn how the proper combination of HDDs and SSDS can satisfy IOPS and latency requirements for common enterprise activities
See some examples of how users have combined HDDs and flash memory to achieve cost effective solutions that meet their application requirements.
