This week’s podcast was recorded on the road a few weeks ago in Silicon Valley. Chris dropped into the Datrium offices in Sunnyvale to talk about DVX, Datrium’s open converged platform. Taking part in the podcast is Sazzala Reddy, CTO and co-founder and Tushar Agrawal, Director of Products.
Datrium DVX is an extension of HCI that scales performance and capacity separately. Persistent storage is deployed on a shared array, with each compute host using local cache in the form of flash storage. You can find out more on a recent blog post covering DVX.
The conversation covers an explanation on why traditional HCI has issues scaling and how Datrium has solved some of these challenges. This leads on to a discussion on the features of DVX releases, including DVX 4.0, which offers backup to public cloud.
During the podcast Sazzala mentions Little’s Law (details here). He also discusses Log Structured File Systems and VMware founder Mendel Rosenblum. A copy of his paper can be found here. Also, here’s the original Google MapReduce paper.
