Can this PowerEdge T440 server handle running a heavily modified version of the Rust game, given its specifications including an Intel Xeon Silver 4208 processor, 2x 8GB RDIMM memory,
a PERC H730P RAID Controller with 2GB NV Cache, and a single 495W hot-plug power supply along with other features such as iDRAC9 Enterprise and OpenManage Enterprise Advanced?

I would not recommend utilizing this Intel Xeon Silver 4208 processor for hosting a Rust game server. The majority of game server software, including the Rust dedicated server, does not take advantage of several CPU cores. Therefore, a high single thread performance rating is essential, which results in incredibly fast individual cores.

This particular CPU has a low clock speed, which leads to a poor single thread performance rating, similar to some higher-end tablet CPUs. For game servers, it is advisable to use an i7, i9, Ryzen, or, if selecting Intel Xeon/scalable, go with Xeon W chips.

According to https://www.cpubenchmark.net/singleThread.html, any CPU on that list with a rating of 2500 or above is suitable for most modern game server hosting, excluding Apple products and mobile/embedded CPUs.

To achieve significant improvement, it is recommended to obtain a CPU with greater single-core performance. Additionally, it is suggested to replace the existing HDD with a SATA/NVMe SSD.

If you are searching for a Rust server that offers a kind atmosphere, responsive server administration, clans, reliable companions, an RPG skill system, and an interactive map, then our project, A Kind Server, might pique your interest.
Our administration team is comprised of individuals over 25 years old with a good sense of humor and are regularly online to help guide you throughout the game, from providing advice on what to do and where to start, to helping you avoid finishing quickly.

If you want to join our project, launch a licensed copy of Rust via Steam, and in the main menu, press the F1 button and enter the console that opens. If that method does not help, navigate to the modified servers tab in the main menu of the game, and type DobriyServer_Oxide2 in the search bar. For those with limited experience, we are happy to help you grasp the game mechanics.
