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.

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. These workloads offer a range of different testing profiles ranging from “four corners” tests, common database transfer size tests, as well as trace, captures from different VDI environments. All of these tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. This allows us to repeat the same workloads across a wide range of storage devices, including flash arrays and individual storage devices. In our worst-case scenario (99th-percentile) latency test we saw the server hit an aggregate of 264.5ms with individual VMs 249.2ms to 276.1ms. Holes for CPU cooler meant the orientation of a Noctua Cooler had the fans blowing upwards rather than to the rear of the case)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.

In the mATX form factor, it is good to have 4x DIMM slots, 2x full length PCIe slots (more on this later), and a 4x PCIe slot, as well as 2x M.2 slots, 8x SATA ports, TONS of fan headers, and more miscellaneous pinned headers at the foot than I know what to do with. This board could service a full tower of parts, and again is a little staggering in versatility. 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.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. Ok, so this board is not perfect. I will start with what I believe to be a design flaw that I currently suffer through, but that may be a deal breaker for many prospect buyers. There is a fundamental and inherent layout and power delivery design incompatibility: you have three PCIe lanes that fight for space and electronics, and there are no ideal configurations to maximize the potential of this board.
