Beyond NVMe-oF Performance Hero Numbers

Erik Smith Leave a comment

When it comes to selecting the right NVMe over Fabrics™ (NVMe-oF™) solution, one should look beyond test results that demonstrate NVMe-oF’s dramatic reduction in latency and consider the other, more important, questions such as “How does the transport really impact application performance?” and “How does the transport holistically fit into my environment?”

To date, the focus has been on specialized fabrics like RDMA (e.g., RoCE) because it provides the lowest possible latency, as well as Fibre Channel because it is generally considered to be the most reliable.  However, with the introduction of NVMe-oF/TCP this conversation must be expanded to also include considerations regarding scale, cost, and operations. That’s why the SNIA Networking Storage Forum (NSF) is hosting a webcast series that will dive into answering these questions beyond the standard answer “it depends.”

RoCE vs. iWARP – The Next “Great Storage Debate”

John Kim Leave a comment

By now, we hope you’ve had a chance to watch one of the webcasts from the SNIA Ethernet Storage Forum’s “Great Storage Debate” webcast series. To date, our experts have had friendly, vendor-neutral debates on File vs. Block vs. Object Storage, Fibre Channel vs. iSCSI, and FCoE vs. iSCSI vs. iSER. The goal of this series is not to have a winner emerge, but rather educate the attendees on how the technologies work, advantages of each, and common use cases.

Our next great storage debate will be on August 22, 2018 where our experts will debate RoCE vs. iWARP. They will discuss these two commonly known RDMA protocols that run over Ethernet: RDMA over Converged Ethernet (RoCE) and the IETF-standard iWARP. Both are Ethernet-based RDMA technologies that can increase networking performance. Both reduce the amount of CPU overhead in transferring data among servers and storage systems to support network-intensive applications, like networked storage or clustered computing.

Join us on August 22nd, as we’ll address questions like:

  • Both RoCE and iWARP support RDMA over Ethernet, but what are the differences?
  • Use cases for RoCE and iWARP and what differentiates them?
  • UDP/IP and TCP/IP: which RDMA standard uses which protocol, and what are the advantages and disadvantages?
  • What are the software and hardware requirements for each?
  • What are the performance/latency differences of each?

Get this on your calendar by registering now. Our experts will be on-hand to answer your questions on the spot. We hope to see you there!
