Access "Caching software adds IOPS to solid-state storage"
This article is part of the Vol. 11 Num. 8 October 2012 issue of Slimmer storage: How data reduction systems work
A new category of storage software is emerging with apps that optimize solid-state storage to help increase I/O performance and fully realize the benefits of flash-based storage. Balancing all the elements of a computing infrastructure is a bit like squeezing a balloon: push one side in and another side pops out. Throughout the evolution of computing, server, network and storage technologies have leapfrogged one another in terms of performance. As the technology of one component improves, the others become bottlenecks in the overall system performance. When it comes to mechanical storage devices, however, it seems the Rubicon has been crossed. Although mechanical hard disk drives (HDDs) continue to be enhanced, most of the advances are in areal density. Capacities within a given form factor continue to improve significantly, yet increasingly, mechanical HDDs simply can’t keep up in terms of IOPS throughput. Fortunately, solid-state drive (SSD) technology has allowed storage to again jump ahead of server throughput requirements. Whereas a 600 GB 15K rpm SAS ... Access >>>

Beware: Solid-state storage approaching the valley of vagueness
by Rich Castagna
Keeping up with solid-state storage requires some technical know-how, but sometimes flash vendors make the technology harder for users to understand.
