Question 1
Q1An infrastructure architect is designing a low-latency storage fabric for a high-frequency trading application. The design mandates utilizing the existing high-speed Ethernet switching infrastructure without incurring the CPU overhead associated with TCP/IP encapsulation for storage traffic. Which foundational storage transport technology meets these specific constraints?
Show answer & explanation
Correct answer: A
NVMe over RDMA Converged Ethernet (RoCE v2) maps NVMe commands natively over an Ethernet network using RDMA, which bypasses the host TCP/IP stack to provide extremely low latency and low CPU overhead. NVMe/TCP incurs the TCP/IP overhead, making it unsuitable given the constraints. Fibre Channel (FC) requires dedicated FC switching, not Ethernet. iSCSI utilizes TCP/IP.
