#121 – NVMe 1.4 Deep Dive Part II with J Metz

4 October 2019 by Chris Evans

This podcast episode continues the discussion with Dr J Metz and focuses on the detail of NVMe 1.4 and NVMe over Fabrics 1.1. Both standards are complete and have been published in the last few months. The conversation today digs deeper into what the new standards offer and specifically how NVMe/TCP becomes “officially” part of the NVMe standard.

The conversation on NVMe/TCP is particularly interesting as it highlights how the protocol will offer significant benefits over iSCSI. The details in the podcast are quite technical and so it’s worth checking out some of the additional background material online. You can find out more on NVMe at the dedicated Architecting IT NVMe microsite.

For more information on the new standards, check out NVMExpress.org. More about Fibre Channel is available at FCIA.org and of course don’t forget to read up on J’s own NVMe content at jmetz.com.
