Looking at performance, we used two SN850 SSDs to get a feel for the peak system capabilities. For our Application Workload Analysis, we did the testing a bit differently using only 2 VMs for SQL Server and then 4 VMs for Sysbench. SQL Server gave us an aggregate average latency of 2ms. For Sysbench we saw aggregate scores of 3,210 TPS, 36.5ms for average latency, and 264.5ms for worst-case scenario latency. Holes for CPU cooler meant the orientation of a Noctua Cooler had the fans blowing upwards rather than to the rear of the case) I needed a board to run unRAID as a file server and as well as hosting a VM or two. A board capable of taking two graphics cards, a x4 SAS controller and the ability to remote admin. AMD CPU's are great value at the time of writing and following an upgrade had a R7 2700X to use - So this board fitted the bill.

So, BMC functionality is there and works pretty well, at least the web management interface. SSH allows only a single session at a time and my system thinks it has an existing active session when it does not. Haven't tried sol. The remote KVM works. I have not tried to install an OS onto the server using the BMC but that is supported by the web interface. This board draws power efficiently, idling with a GTX 1660 super, 4x enterprise SAS hard drives, 2x NVME drives, 2x SSDs, a Ryzen 5 1600, 2x fans, and a AIO CPU cooler at a mere 40 watts. Its chipset handles heat well: I have seen 0 meaningful throttling at hot-but-not-alarming temperatures. When I enter the BIOS via the IPMI web Interface, it is not showing any content. I provided the correct credentials into the login mask. So, everything has been running great with my Ryzen 5 5600X, 2 x 16GB ECC KSM32ES8/16ME (on QVL), and X570D4U-2L2T…butIt's currently running unRAID booting from the internal USB3 (needed to buy an adapter) with 8 drives in to a SAS controller sitting in the x4 PCIe expansion. unRAID boots to the internal graphics which is nice and I have a R9 Nano for a Windows VM and an old AMD card for Server 2016 VM. I have a USB soundcard in one of the rear USB ports and a small hub in the other for the keyboard and mouse. SLOT5: PCIe4.0* x1 [FCH] *Supports PCIe3.0 when using AMD Ryzen™ 5000, 4000 and 3000 G-Series Desktop Processors with Radeon™ Graphics This is a highly revised review. Originally, I was disappointed by this board due to problems that I was having... inconsistent boot experiences with some outright failures, the BMC not functioning (not taking an IP lease and appearing as an unknown device), and unreadable screen resolution and display problems. Quite awful.

Populated with 64GB of fast 3200MT/s ECC DDR4 (Kingston p/n# KSM32ED8/32ME), 8C/16T Processor (Ryzen 7 2700), + Adaptec RAID Controller with it’s own dedicated DDR cache memory and SSD cach for hot data provides me with a balanced system. The dedicated RAID offloads the processor, so my system is well positioned to run multiple virtual machines. Each SQL Server VM is configured with two vDisks: 100GB volume for boot and a 500GB volume for the database and log files. From a system resource perspective, we configured each VM with 16 vCPUs, 60GB of DRAM and leveraged the LSI Logic SAS SCSI controller. As others have mentioned, the RAM slots are REALLY close to the CPU. My CPU cooler hangs over the nearest RAM slot so I'm limited to using just 2 of the 4 slots, at least until I go to the trouble of replacing the CPU cooler. The KVM is available via HTML5 or Java, and one small perk over the Supermicro HTML5 client is the ability to easily mount CD/DVD ISO media directly from the HTML5 KVM client. Since the inclusion of the BMC is the defining feature of this motherboard, executing this feature well is a must and the solution on the X570D4U-2L2T mostly works well and does not require any additional licensing for full functionality.Since this is based on Ryzen, it is a single NUMA node design. AMD EPYC 7001 8-core servers, such as those based on the AMD EPYC 7251 had four NUMA nodes which created a lot of inter-die traffic. With Ryzen, one does not have to worry about that on these lower-cost platforms. Supports PCIe3.0 x8 when using AMD Ryzen™ 5000, 4000 G-Series Desktop Processors with Radeon™ Graphics Supports PCIe3.0 x16 when using AMD Ryzen™ 5000, 4000 G-Series Desktop Processors with Radeon™ Graphics Now a year later, I discovered after a prolonged power outage that drained my UPS and forced a restart (which completely failed) that the ATX power supply in my server was bad. Second, the electronics. The primary and secondary PCIe slots share 16x worth of lanes. This is absurd! If you have anything plugged into the second 16x slot, all 8x of its power is robbed from the primary 16x slot, and not from the 4x where you might expect. This means that you have to choose between your GPU getting its full bandwidth and power OR running an expansion card on the secondary physical 16x lane and having both cards operate at 8x power. This is a massive flaw in my opinion, even if it only affects some users. I cannot think of a good reason why the lanes are allocated like this rather than isolating the primary 16x lane and netting a little extra power to split 12x across the remaining slots.
