[email protected] www.ngxstorage.com Storage Performance Development Kit (SPDK) Intel driven and open-source user space NVMe driver highly parallel access directly to an SSD avoids all locks in the I/O path by message passing a full block stack as a user space library NVMe-oF support 

NVMe-over-Fabrics with RDMA transport Independently scales Scale to 10’s of PB with initial version and 100’s of PB in future releases ©2022 NGX Storage.All rights reserved. [email protected] www.ngxstorage.com Why Scale-out NVMe Block? Reduced TCO low latency access to SSD over PCIe Interconnect NVM Express metadata+storage service (IOPS/throughput and client connections scaling) storage (capacity scaling) Data center scale and SDS enabling Public/On-Prem cloud deployments(future versions)
