The latency/IOPS curve, revisited in the age of flash

Posted by Sheryl Koenigsberg on Jul 2, 2018

One of the fundamental truths about storage performance is that there is a predictable curve that relates IOPS to latency. At first, latency rises gently, sometimes even imperceptibly, as IOPS rise. At some inflection point, this changes, and suddenly every incremental unit of IOPS that a system takes on results in an exponential increase in latency.

Customer Story: Remote Tech Group

Posted by Sheryl Koenigsberg on May 17, 2018

Remote Tech Group (RTG) is the most advanced Act! hosting provider in the U.S.  Running on IBM infrastructure, the team at RTG recognizes that while Act! runs on the .NET platform, customers are logoaccustomed to the performance afforded by newer technologies like JSON and REST.  With that in mind, they sought a solution to provide better performance.

Their evaluation of Infinio was a success, first with a RAM-only deployment, then even more so when they added SSDs. they found most of their I/O requests to be cacheable, which of offloaded work the aging storage, while delivering the enterprise-class response time their customers have come to expect.

Server-side flash: how best to deploy

Posted by Sheryl Koenigsberg on Apr 16, 2018

We're a caching company, so it will probably come as no surprise that we think the flash in your servers (SSDs, PCIe cards, NVMe devices, and flash cards) are best deployed as a cache, rather than exposed as a raw storage device.

Results from our storage survey

Posted by Sheryl Koenigsberg on Mar 28, 2018

A few months ago we surveyed over 1,000 IT decision makers about what experience they've had with server-side storage; that is, hyper-converged infrastructure, vSAN, software-defined storage, and server-side cache. We've compiled the results into a short presentation you can download.
