StorNext File System (SNFS) is a software platform designed to manage massive amounts of data throughout its lifecycle, delivering the required balance of high performance, data protection and preservation, scalability, and cost. StorNext was designed specifically for large unstructured data sets, including video workloads, where low latency, predictable performance is required. SNFS is a scale-out parallel file system that is POSIX compliant and supports hundreds of petabytes and billions of files in a single namespace. Clients connect to the front-end using NAS protocols or directly to the back-end storage network with a dedicated client. Value-add data services enable integrated data protection and policy-based movement of files between multiple tiers of primary and secondary storage, including cloud. Storage and server-agnostic, SNFS may be run on customer-supplied hardware, or Quantum server and storage nodes.

Filesystem Creation Notes

Created a StorNext file system across all 10 nodes. Total 20 LUNS with 100 NVMe disks. A single Stripe group, stripebreadth=2.5MB, round-robin pattern. Metadata and User data combined into a single Stripe group and striped across all LUNS in the stripe group

Storage and Filesystem Notes

Each F1000 contains 10 NVMe devices configured in RAID 10, then sliced into two LUNS per node.

Memory Notes

Storage nodes have 64GB of memory for a total of 640GB. Clients have 192GB of memory each for a total of 2,688GB. The Prime has 64GB of memory

Stable Storage

The F1000 storage node does not use write cache to temporarily store data in flight, writes are therefore committed to disk immediately. All Data is protected in the file system by a RAID 10 storage configuration including metadata. The entire SUT is protected with redundant power supplies, both storage nodes and clients. F1000 and clients have two NVMe system devices in a 1+1 configuration for OS redundency. Metadata servers are configured in a high availability state, this ensures file system access in the event of a metadata server failure.

Solution Under Test Configuration Notes

The solution is a standardized configuration by Quantum with Xcellis workflow directors managing metadata for the file system. F1000 storage nodes are off the shelf nodes designed for high perpormance streaming media in addition to high IOPS for very randomized workflows. The file system was configured, as per the "Filesystem Creation Notes" listed above. The purpose of this is to take into account a mixed workflow of random and sequential processes, including combining metadata striped across the file system.

Other Solution Notes



The entire SUT is connected per the SUT diagram. Each of the 14 clients is direct connected using iSER/RDMA. No special tuning parameters were used in tuning the connections. One file system was created and shared as StorNext file system.
