4 NVMe and I/O Topologies for Dell EMC PowerEdge Servers
1. Introduction
Server users considering Non-Volatile Memory Express (NVMe) storage drives seek
top-of-the-line performance. The PCIe interface will improve the data delivery path and
simplify the software stack, resulting in significant latency reduction and bandwidth
increases for storage data transfer transactions.
PowerEdge rack servers have unique configurations that are designed for specific value
propositions, such as bandwidth, capacity or I/O availability. There may be other
configurations that are better suited to the specific goals of your enterprise solution.
This reference guide is intended to provide the value propositions for each
configuration; to help customers choose the right configuration for their objectives. It
also provides detailed illustrations of NVMe and system I/O topologies, so that Solution
Architects can choose the best hardware configuration, and optimally design and
configure customer software solutions and workloads.
