Cloudflare Operations Engineer Chris Howells emphasized in a new statement that the company has no complaints about the performance of its Ice Lake generation Xeon processors. The problem is that the server on Intel chips is too “power hungry”. It consumes several hundred watts more power than solutions based on AMD processors. This is why Cloudflare chose AMD’s 64-core Epyc 7713 chips.
Also, three 960 GB Samsung drives, Cloudflare developers will prefer two 1.92 TB each. When comparing performance and economic efficiency, the company decided to abandon 512 GB of RAM in favor of 384 GB.
However, the company announced that DDR4-3200 will be used instead of DDR4-2933. At the expense of a small increase in cost, Cloudflare provided a tangible performance boost. At the same time, Mellanox ConnectX-4 network adapters (2 × 25 Gbps) were retained in the company. With the existing architecture, they turned out to be quite enough.
