Direct Attached Storage (DAS), offers a lot of advantages in terms of speed and latency, but comes with a suite of problems. If nothing else, it forces applications to deal with data integrity and resiliency issues instead of having it as part of SAN. Chris Evans looks at how WekaIO addresses the shortcomings of DAS while keeping the high-performance and low latency. At Storage Field Day last month, they showed how their scale-out parallel file system can provide exceptional performance that’s only limited by the bandwidth of the network card. By rewritting at the file system layer and lower, WekaIO is able to offer distributed storage built to take full advantage of modern storage media.
