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 network interface controllers (NICs)), or cabling the appropriate device chassis to a server, composable enables the virtual connection of these resources at the device level as and when needed.
Not bound by a fixed ratio of central processing units (CPUs) to storage, 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 graphics processing units (GPUs) and / or field-programmable gate arrays (FPGAs).
DriveScale, founded in 2013 (first release in 2016), is an independent vendor that developed a composable solution that essentially maps direct-attached storage (DAS) devices to servers in an Ethernet-connected environment, using DriveScale or third-party storage adapters. Instead of a purpose-built, blade-style, modular chassis, DriveScale’s solution is built around a software composing engine that creates clusters of third-party storage devices and diskless servers using Internet Small Computer Systems Interface (iSCSI) and non-volatile memory express over fabric (NVMe-oF) protocols. Using Ethernet to connect all resources with server nodes and the Composer software, DriveScale clusters can scale to thousands of nodes.
