Have you heard about QUIC? Although initially proposed as the acronym for “Quick UDP Internet Connections,” IETF’s use of the word QUIC is not an acronym; it is merely the name of the protocol. QUIC is a new UDP-based transport protocol for the Internet, and specifically, the web. Originally designed and deployed by Google, it already makes up 35% of Google’s egress traffic, which corresponds to about 7% of all Internet traffic. Due to its ability to improve connection-oriented web application performance, it is gaining enthusiastic interest by many other large Internet players in the ongoing IETF standardization process, which is likely to lead to an even greater deployment.

When NVMe™ over Fabrics Meets TCP
In the storage world, NVMe™ is arguably the hottest thing going right now. Go to any storage conference – either vendor-related or vendor-neutral, and you’ll see NVMe as the latest and greatest innovation. It stands to reason, then, that when you want to run NVMe over a network, you must understand NVMe over Fabrics (NVMe-oF). Meanwhile, TCP is by far the most popular networking transport protocol both for storage and non-storage traffic.
TCP – the long-standing mainstay of networking – is the newest transport technology to be approved by the NVM Express ® organization, enabling NVMe/TCP. This can mean really good things for storage and storage networking – but what are the tradeoffs?
With any new technology, though, there can still be a bit of confusion. No technology is a panacea; and with any new development there will always be a need to gauge where it is best used (like a tool in a toolbox).
Learn more on January 22nd when the SNIA Networking Storage Forum hosts a live webcast, What NVMe™/TCP Means for Networked Storage. In this webcast, we’ve brought together the lead author of the NVMe/TCP specification, Sagi Grimberg, and J. Metz, member of the SNIA and NVMe Boards of Directors, to discuss:
- What is NVMe/TCP
- How NVMe/TCP works
- What are the trade-offs?
- What should network administrators know?
- What kind of expectations are realistic?
- What technologies can make NVMe/TCP work better?
- And more…
Obviously, we can’t cover the entire world of NVMe and TCP networking in an hour, but we can start to raise the questions – and approach the answers – that must be addressed in order to make informed decisions. Speaking of questions, bring yours. Sagi and J. will be answering them on the 22nd. Register today to save your spot.
