Dell EMC PowerEdge R740xd NVMe Server Evaluation

At present, the evaluation of Dell EMC PowerEdge R740xd NVMe server, I believe that many friends are not very familiar with, so the following editor also collected relevant information, I hope to help you.

Dell EMC PowerEdge R740xd was released more than three years ago, when the company upgraded its family of PowerEdge servers from Broadwell to highly powerful processors. R740xd is a branch of R740, the "extreme disk" version with more storage options. We reviewed Dell EMC PowerEdge R740xd and liked it very much. In fact, we gave it our editor's choice award, and we used a team of eight as the backbone of almost all our enterprise tests. Fast forward to last year, the dawn of the second-generation Intel Xeon Extensible CPU. We also upgraded our lab R740xd with the new processor, which will be explained in more detail here. Today, we will learn more about the NVMe storage options for this upgraded R740xd server. Like all PowerEdge products, R740xd is highly configurable. As far as NVMe is concerned, there are many options. First of all, the front cabin. Depending on the configuration of the server at the time of purchase, users can use all the front bays of the 2.5-inch NVMe solid state drive. To maximize bandwidth, users can configure the front rack as 12 NVMe SSDs and 12 SAS SSDs. In groups of four, NVMe solid state drives can be mapped to one of the CPU via PCI expansion cards. If the maximum NVMe storage capacity at the front end is more in line with your requirements, then 24 shelves can be filled with NVMe SSD, and every 12 shelves can be mapped to PCIe switches, allowing the system to over-configure PCIe channels to more NVMe drives while reserving I-NVMe O slots, thus achieving low-latency CPU access for 12 devices per CPU.
