LightOS & LightField Revolutionize Cloud Infrastructures by separating storage and compute – all on existing commodity hardware
Lightbits Labs
Storage Management Innovation of the Year
Entry Description
When Lightbits Labs emerged from stealth mode in March, the company unveiled groundbreaking storage solutions that address the expense and waste of underutilized data center storage. Lightbits’ solutions bring the hyperscale agility enjoyed by the world’s largest public cloud companies to private clouds and SaaS providers.
With the launch of the industry’s first NVMe/TCP commercial software-defined storage solution, LightOS, and LightField PCIe storage acceleration card, Lightbits revealed how storage can easily scale independently from compute without changing the data center clients or network infrastructure through standard networks.
To get there, Lightbits looked to flash memory as a way for companies to save money. LightOS is unique because it is built around NVMe over everyday high-performance ethernet, TCP/IP and provides a Global Flash Translation Layer (GFTL) which enables pooled storage. Putting the power of the SSDs together, separating read and write, and creating different pipelines within the SSDs means users can gain the best service and quality and speeds for each application - helping them achieve unlimited scale at the lowest total cost of ownership.
With LightOS and LightField, application owners can fully use truly composable storage with the highest performance that is indistinguishable from direct-attached storage (DAS) SSDs. The transition from fast but inefficient DAS to disaggregated NVMe storage results in dramatically higher storage efficiency and availability at scale.
The Lightbits approach was based on years of pioneering work in storage by its C-suite and developers. Rather than looking for ways to improve on existing storage solutions that are quickly becoming outmoded, Lightbits looked at ways to harness existing hardware for optimized performance. By pulling together multiple NVMe SSDs into one large pool, the LightOS GFTL boosts performance significantly – supporting millions of IOPs at latencies that are similar to DAS SSDs. All the while, LightOS is delivering rich data services while enhancing the endurance of the commodity SSDs.
As the storage industry’s pioneer in NVMe/TCP, Lightbits helped drive the standardization effort and worked closely with NVM Express and its member companies, including taking a leadership role in the initial development of the standard specifications. Designed to layer over existing software-based TCP transport implementations as well as future hardware accelerated implementations, NVMe/TCP lets large-scale data centers utilize their existing, ubiquitous TCP/IP infrastructure to realize NVMe’s performance benefits.
