Why is PCIe Considered the Holy Grail for Composability?

Posted on

PCIe is considered the holy grail for composability because it is the common language for ALL core building blocks of the datacenter. With Liqid Composable Infrastructure, we now have for the first time all of the core data center resources actually living on a common bus.

When storage migrated away from SATA and SAS it moved to NVME, which lives on the PCIe bus. And when data center resources like GPUs and FPGAs became relevant, they also moved to the PCIe bus. Now the data center has all the core resources speaking a common language - compute, networking, storage, GPUs, FPGAs - over that common bus, that common language, which is PCIe. And this is the common thread that makes our solution bare metal capable.

Without these resources speaking the same language, you'd be reliant on technologies like virtualization, protocol translation, electrical translation, etc. The fact that all of these resources connect together by PCIe is what enables us to compose at the bare metal. So for today, PCIe is the appropriate interface to interconnect all of these devices together.

In the future, if there is a better interconnect, perhaps something like a GenZ, we fully plan to adopt to the appropriate physical interface that's out there. Today, the appropriate physical interface is PCIe. It is the holy grail of composability.
