Western Digital NVMesh Solutions

Leveraging Excelero’s NVMesh elastic NVMe technology, the Western Digital high-performance Ultrastar Serv24-4N NVMe Storage Server provides superior performance, parity-based data protection, and improved storage efficiency to enable customers avoid further investments in new networking technologies. The Ultrastar Serv24-4N NVMe Storage Server combines the speed of NVMe SSDs with a quad-server architecture in a 2U package, to deliver high density storage and extreme performance.

Key Benefits:

  • Enables existing applications to access pooled NVMe storage across a network at local speeds and latencies.
  • Enables 100% hyper converged infrastructure by full logical disaggregation of storage and compute.
  • Distributed block storage enables customers to leverage NVMe at scale without having to change workflows.
  • Delivers deterministic performance that scales linearly at near 100% efficiency.

NVMesh is a Software-Defined Block Storage solution that features Elastic NVMe, a distributed block layer that allows unmodified applications to utilize pooled NVMe storage devices across a network at local speeds and latencies.
Distributed NVMe storage resources are pooled with the ability to create arbitrary, dynamic block volumes that can be utilized by any host running the NVMeshblock client. These virtual volumes can be striped, mirrored or both while enjoying centralized management, monitoring and administration.
