Arm Server Update, Spring/Summer 2021

As usual, we are overdue for an update on all things Arm Servers! Today’s announcement of the Arm v9 specification is a great time to review the state of Arm Servers, and what has changed since our last update.

First, let’s review our last update. Marvell canceled the ThunderX3 product, Ampere had announced the Altra but it wasn’t shipping, AWS Graviton was available, and Nuvia was designing a processor.

Fast forward to today, and the Ampere Altra’s are now becoming available, with limited stock via the Works on Arm program at Equinix Metal, and some designs shown off by Avantek, a channel supplier. Mt. Snow and Mt. Jade, as they are known, are also formally designated as “ServerReady” parts, passing standards compliance tests.

Nuvia, the startup that was designing a new Arm Server SoC from the ground up, was purchased by Qualcomm, in an apparent re-entry into the Arm Server market (or for use in Windows on Arm laptops?). Don’t forget, they previously had an Arm Server part, the Centriq, though they scrapped it a few years ago. So, it now remains to be seen if Nuvia will launch a server-grade SoC, or pivot to a smaller target-device.

The other emerging trend to cover is the role of Arm in the Edge Server ecosystem, where the trend of pushing small servers out of the datacenter and closer to customers and users is rapidly gaining momentum. In this scenario, non-traditional, smaller devices take on the role of a server, and the energy efficiency, small form-factor, and varied capabilities of Arm-powered single board computers are taking on workloads previously handled by typical 1U and 2U rackmount servers in a datacenter. But, small devices like the Nvidia Jetson AGX, RaspberryPi Compute Module 4, and NXP Freeway boxes are able to perform Edge AI, data caching, or local workloads, and only send what is necessary up to the cloud. This trend has been accelerating over the past 12 – 18 months, so, we may see some more niche devices or SoC’s start to fill this market.
