Systems Papers - Towards an Adaptable Systems Architecture for Memory Tiering at Warehouse-Scale

Hello new and old subscribers!

This is one of my first posts on Substack - if you have any feedback, I would love to hear it! Feel free to respond to this email with what is on your mind or if you have found any interesting papers recently.

This week’s paper is Towards an Adaptable Systems Architecture for Memory Tiering at Warehouse-Scale.

Applications running in datacenter environments require resources to operate, like dynamic random access memory. DRAM is both expensive and in high demand. As alternatives to DRAM emerge, new approaches to trading off performance for cost became available to datacenter applications.

To use this new resource type while limiting the impact to application performance, the authors proposed, built, and deployed at scale a new system called Transparent Memory Tiering System (TMTS).

When deployed at scale, TMTS replaced 25% of DRAM with lower cost solutions, while incurring little performance impact to the vast majority of applications!

The paper review is best enjoyed on my blog.

Discussion on Hacker News and Twitter.

Until next time,
