#2Where have you been? (hint: already done by someone else)

#3> The system has 2 CPUs with 64 PCIe Gen 4 lanes each, giving us plenty of PCIe lanes to connect NVMe SSDs
Imagine if they used EPYC CPUs... 160 PCIe lanes.

#480M 512 byte I/O per second. That’s 10M 4KB I/O per second. That’s not groundbreaking.

They also did 25M 4K IOPS on the same system. Anyway, it's basically an ad for Intel® Xeon® and Optane®.

That looks close to the maximum rate of an optane 5800x... 1.5 million 4k iops * 16 devices = 24 million 4k iops. It also looks close to the maximum of pcie4, 16 * 7.8GB / 4K = 32M > 25M.

No.Extending your reasoning, it would just be 1 40GB I/O per second. Each io request has a fixed cost, which is better measured with small requests. Bandwidth is not really relevant here.

#8This makes for a great database server.

#10So what is the price for such a system
2x$8k for the CPUs + 16x$2.2k for the drives + rest of the system >= $50k
