World’s fastest NVMe-AFA software

What is NVEdge?

NVMe All-Flash Arrays

Excelero NVEdge is block storage software for building NVMe All-Flash Arrays (NAFAs) that leverage traditional controller-based high availability (HA) storage architectures. NVEdge takes maximum advantage of NVMe SSDs with demanding and fast-growing application categories such as AI, ML, GPU and Edge computing.

OEMs and Tech Giants

The NVEdge software is targeted at OEMs, large integrators and Tech Giants that are building disaggregated NAFA solutions. NVEdge NAFA Solutions will serve:

  • Cloud data centers where a rack is a single failure domain, yet disaggregated NVMe single-chassis storage needed to be HA.
  • Deployments requiring an HA NVMe storage array with local NVMe performance, but without the need for massive scale, such as Edge locations.


NVEdge delivers Excelero’s hallmark extreme IOPs performance, throughput and cost efficiency via the NVMe over Fabrics (NVMeoF) protocol – supporting NVMeoF standards. It is verified as the fastest NVMe AFA software on the market with over 2.7M 4K IOPs on a 100Gb link – achieving full bandwidth while being thin provisioned at up to a 1000X oversubscription rate.

Enterprise Storage Features

NVEdge has a scale-up architecture and leverages NVMe over Fabrics (NVMe-of). The software provides an elegant answer for settings that demand high availability as well as exceptional performance. Excelero NVEdge provides important enterprise storage features for simplified deployment, efficiency and operation: RAID10 data protection, thin provisioning and checksums.


Excelero NVEdge enables x86 systems and those based around SmartNIC-based architectures such as Mellanox BlueField™ and Broadcom Stingray.™ Based in part on SPDK for writing high performance, scalable, user-mode storage applications, NVEdge supports both RDMA and TCP/IP networking.

“Throughout its history, Excelero has pursued a software-defined storage strategy that offered maximum deployment flexibility for their customers. Excelero already supports a wide variety of different server-based storage nodes, but the Excelero NVEdge announcement further extends the choice of deployment options to customers that need to deploy high-performance NVMe-based storage in a single chassis, commodity hardware platform that also needs to support high availability.”
