The SPEC SFS(R) 2014 Reference Solution consists of a TDV 2.0 micro-cluster appliance, based on Intel Avoton SoC nodes, connected to an ITM-33 storage cluster using the NFSv3 protocol over an Ethernet network.

The ITM-33 cluster, built on proven scale-out storage platform, provides IO/s from a single file system, single volume. The ITM-33 accelerates business and increases speed-to-market by providing scalable, high performance storage for mission critical and highly transactional applications. In addition, the single filesystem, single volume, and linear scalability of the BSD based operating system enables enterprises to scale storage seamlessly with their environment and application while maintaining flat operational expenses. The ITM-33 is based on enterprise-class 2.5" 10,000 RPM Serial Attached SCSI drive technology, 1GbE Ethernet networking, and a high performance Infiniband back-end. The ITM-33 is configured with 4 nodes in a single file system, single volume.

Filesystem Creation Notes

The file system was created on the ITM-33 cluster by using all default parameters.

The file system on the load generating clients was created at OS install time using default parameters with an ext4 file system.

Storage and Filesystem Notes

The storage in the load generating clients did not contribute to the performance of the solution under test, all benchmark data was stored on the IFS file system and accessed via NFSv3.

Transport Configuration Notes

All NFSv3 benchmark traffic flowed through the DCS-7150S-64-CL Ethernet switch.

All load generator clients were connected to an internal switch in the micro-cluster appliance via 2.5GbE. This internal switch was connected to the 10 GbE switch.

The Infiniband network is part of the ITM-33 storage node architecture, and is not configured directly by the user. It carries inter-node cluster traffic. Since it is not configurable by the user it is not included in the switch list.

Processing Element Notes

Each ITM-33 storage node has 2 physical processors with 4 cores and SMT enabled.

Each load generator had a single physical processor.

Memory Notes

Each storage controller has main memory that is used for the operating system and for caching filesystem data. A separate, integrated battery-backed RAM module is used to provide stable storage for writes that have not yet been written to disk.

Stable Storage

Each ITM-33 storage cluster node is equipped with an nvram journal that stores writes to the local disks. The nvram has backup power to save data to dedicated on-card flash in the event of power-loss.

The load generating clients and all components between them and the storage cluster are not stable storage and are not configured as such, and thus will comply with protocol requirements for stable storage.

Solution Under Test Configuration Notes

The system under test consisted of 4 ITM-33 storage nodes, 2U each, connected by QDR Infiniband. Each storage node was configured with a single 10GbE network interface connected to a 10GbE switch. There were 32 load generating clients, each connected to the same Ethernet switch as the ITM-33 storage nodes.

Other Solution Notes



Each load generating client mounted the single file system using NFSv3. Because there were four ITM-33 nodes, the first eight clients mounted the file system from the first ITM-33 node, the next eight clients mounted the file system from the second ITM-33 node, and so on. The order of the clients as used by the benchmark was round-robin distributed such that as the load scaled up, each additional process used the next node in the ITM-33 cluster. This ensured an even distribution of load over the network and among the ITM-33 nodes.
