One of the interesting [1]highlights of September was finally having our hands on an [2]AmpereOne server! After years of being eager to test Ampere Computing's next-generation AArch64 server processors, Ampere sent over their 192-core flagship server processor for a few weeks of testing. The review server was comprised of the AmpereOne A192-32X flagship model within a Supermicro ARS-211M-NR 2U server.

Now that I'm through with the AmpereOne testing with only having access to it for a few weeks, I just wanted to summarize some of the tests for those that missed any of the articles as well as a few words on the Supermicro ARS-211M-NR server. The Supermicro ARS-211M-NR 2U AmpereOne server uses Supermicro's R13SPD motherboard. This server/motherboard support a single socket AmpereOne processor up through the flagship A192-32X SKU, 16 DIMMs for up to 4TB of ECC Registered DDR5-5200 memory, four PCIe 5.0 x16 double-width GPUs/accelerators, dual 25Gb SFP28 connections, and four 2.5-inch U.2 NVMe hot-swap bays. The R13SPD supports DDR5-5200 speeds when running in one DIMM per channel or DDR5-4400 when at two DIMMs per channel.

The Supermicro ARS-211M-NR is a fairly comprehensive single-socket AmpereOne server platform with all the bells and whistles one would expect for a higher-end server and with the space for four PCIe 5.0 double-width expansion cards can make for a nice AI inferencing server or similar.

With the AmpereOne A192-32X having a usage power rating of 276 Watts, it can be comfortably cooled with air cooling. The Supermicro ARS-211M-NR server features four 8cm fans for plenty of cooling.

The Supermicro ARS-211M-NR server features dual 2000 Watt redundant Titanium-level power supplies. The power supplies can accommodate the server being fully loaded with multiple drives and accelerators/GPUs but otherwise won't come anywhere close to hitting those power levels if just planning to make use of an AmpereOne processor and 8~16 DIMMs of DDR5.
