Inside PernixData Engineering: Clustered acceleration deep dive
The last day of VMworld is always an interesting one, the buzz slowly dies done and everything is done at a more relaxed pace. However instead of enjoying this laid back moment, I decided to go back to the office and meet up with some of the engineers to shoot some videos.
In this video Woon and I take a deepdive in to clustered acceleration. Woon Jung, one of the core data path engineers, provides background about the challenges of write back. He gives insight about the clustering functions such as the cache coherency protocol and the support of remote flash access after a vMotion. During the interview I ask him to give me some examples of the surprises they encountered during the development of the product. This leads to some interesting information of the world of flash and kernel scheduling overhead.
