Excelero Storage

Excelero Storage is a software company that provides software-defined storage solutions for I/O intensive workloads. The company's flagship product, NVMesh, is designed to enable shared NVMe across any network with support for local or distributed file systems. NVMesh is a container-native software-defined storage solution that delivers low-latency distributed block storage for web-scale applications. The technology is particularly suited for large data centers with over 100,000 nodes, as it avoids any centralized capability for the data path, allowing direct application of NVMe to the data path.

Excelero's solution is designed to work within Kubernetes environments, offering container-native storage that maintains bare-metal storage performance characteristics. The company achieves this by controlling deployments of client and target device drivers with privileged containers, which leaves the data path unaffected by the containerized nature of the Kubernetes environment. In a production environment of a Tier-1 web firm, Excelero's technology demonstrated application-level performance 15-20% higher than bare-metal cases by aggregating several remote NVMe drives in a virtual volume presented to user containers running applications.

The company's technology also addresses challenges related to fault tolerance and high availability at scale. Excelero's architecture supports logical disaggregation of storage from compute, enabling the movement of client workloads between compute nodes in case of application server failures. The system is designed to handle rolling security or scheduled upgrades to storage nodes and prevent downtime during rare edge cases or storage cluster issues.
