Composable Infrastructure direct-connects compute and storage resources dynamically, using virtualized networking techniques controlled by software. Instead of physically constructing a server with specific internal devices (typically storage or NICs), or cabling the appropriate device chassis to a server, composable enables the virtual connection of these resources at the device level as needed, when needed.

Not bound by a fixed ratio of CPUs to storage or networking, etc., these products can assemble or “compose” bare-metal compute systems with the desired hardware configuration, essentially at run time. And, they can “disassemble” it when no longer needed, returning those resources to a common pool. Some solutions also support GPUs and/or FPGAs.

Liqid creates bare metal server instances from industry-standard chassis containing flash, GPUs, FPGAs and CPU and memory modules, including Intel Optane persistent memory devices. The Liqid product is a PCIe switch that runs the Liqid Command Center composable management software connecting resources from approved hardware. Liqid is hardware agnostic, but also manufactures NVMe storage devices in U.2 and PCIe AIC formats.

The PCIe cables connecting the switch to these chassis essentially replaces the backplane – Liqid calls it a “rack-level backplane”. This allows Liqid to connect storage, GPUs and FPGAs into the composable fabric servers.

Liqid Grid

At the heart of Liqid’s technology is Liqid Grid, a 2U managed PCIe switching fabric with 24 PCIe Gen3 x4 ports (configurable to x8 or x16). Liqid Grid provides 192 GB/s of full duplex bandwidth with a fabric latency of ~150ns. This system runs the Liqid Command Center software which controls the composing process.
