A highly-adaptable server like the Power Edge R740 provides Tad Walsh extensive configuration flexibility, allowing it to be tailored to the specific demands of a wide range of workloads. Yet even more differentiated designs in the same 2-socket space are needed to meet the emerging demands of highly data-intensive workloads. Thus we see additional servers (the Power Edge R740xd and R740xd2) in the same general space, in order to provide peak

for the segregation of operating system from data.

The R740 offers broad configuration flexibility, allowing it to be tailored for the requirements of a wide range of workloads and applications including OLTP, Decision Support, Xaa S, web tech, server virtualization, desktop virtualization (VDI), and HPC. For users needing to drive application performance beyond the 2-socket range, the R740 also supports numerous GPU and FPGA options, enabling users to stay at the forefront of emerging application areas such as ML/DL, AI, and business-oriented HPC.

In the realm of high availability features, the R740 offers multiple hot-plug power supplies for full redundancy, and these power supplies can be chosen from a range of wattages, allowing users to choose the appropriate type of power supply based on the needs of their workloads and server configuration. Cooling comes from up to six fully-redundant hot-plug fans.
