Software-defined storage architectures

In data centers, the IO path to storage is long and complex. It comprises many layers or “stages” with opaque interfaces between them. This makes it hard to enforce end-to-end policies that dictate a storage IO flow’s performance (e.g., guarantee a tenant’s IO bandwidth) and routing (e.g., route an untrusted VM’s traffic through a sanitization middlebox). We are researching architectures that decouple control from data flow to enable such policies.

Microsoft Research Storage Toolkit

November 2014

The Microsoft Research Storage Toolkit enables effective and accessible research in Software Defined Storage by adding I/O classification functions to the Windows 8.1 storage stack and exposing selected flows of I/O requests to a user-supplied program written in C# which can easily inspect or modify them. Parts of the Toolkit have supported our own recent…
