What is Computational Storage?
An architecture in which data is processed in close physical proximity to the storage device. Primary benefit: reduce the amount of data that must move between the storage plane and the compute plane.
Traditional vs. Computational Storage
The CPU processes data compute tasks such as compression; data is sent between storage and compute planes.
Computational Storage Architecture shifts data compute tasks to a hardware accelerator (FPGA), offloading the CPU. Data stays close to the compute, avoiding data movement on the slower CPU compute plane.

CSS: Computational Storage Service
What is a CSS?
A data service or information service that performs computation on data where the service and the data are associated with a storage device.
It’s important to remember a CSS is not a device or module itself—rather it’s the acceleration services performed by a CSP or CSD. For example, the compression service that our 250-U2 can provide (through Eideticom’s NoLoad IP) is a CSS.
CSP: Computational Storage Processor
What is a CSP?
As you can see in the diagram, the CSP is a separate device from FLASH persistent data storage. Acceleration services (CSS), such as compression, are offloaded from the CPU to the FPGA.
As a further advantage, the 250-U2 (a CSP module) transfers data to/from FLASH using peer-to-peer transfers, offloading the CPU from not only acceleration but data movement. This is enabled using Eideticom’s NoLoad IP.

M.2 Accelerator Module
BittWare (a Molex company) is a strategic investor in Eideticom, a recognized thought leader in NVMe based Computational Storage solutions.
Their mission is to develop world-class Computational Storage Solutions for cloud and enterprise data centers. Eideticom’s NoLoad® Computational Storage Processor (CSP) is accelerating data center infrastructure, enabling greater scalability and dramatically lowering cost.
Los Alamos National Laboratory Collaboration
Eideticom and Los Alamos National Laboratory are collaborating on a storage acceleration solution using the BittWare 250-U2 computational storage processor. Key news from the press release:
- World’s first NVMe-based computational storage compressed parallel filesystem built using Eideticom’s NoLoad® CSP and deployed in LANL’s Lustre/ZFS-based HPC parallel filesystems.
- NoLoad CSP’s high performance compression engines provide scalable offload of storage centric services and enable capacity increases with no impact on performance.
- NoLoad’s NVMe-compliant interface simplifies deployment of computational offload by making it straightforward to consume in servers of all types and across all major operating systems.
