The SPEC SFS(R) 2014 Reference Solution consists of a Dell PowerEdge R630 - rack-mountable - Xeon E5-2640V4 2.4 GHz - 96 GB - 600 server, based on Intel Xeon E5-2640V4 2.4 GHz - 8 core processor, connected to VMware 24 nodes cluster using the NFSv3 protocol over an Ethernet network.

The PowerEdge R630 server, provides IO/s from 8 file systems, and 8 volumes. The PowerEdge R630 accelerates business and increases speed-to-market by providing scalable, high performance storage for mission critical and highly transactional applications. Based on the powerful family of Intel E5-2600 processors, the PowerEdge R630 uses All SSD Flash storage architecture for block, and file, and supports for native NAS, and iSCSI protocols. Each PowerEdge R630 server uses a single socket storage processors, full 12 Gb SAS back end connectivity and includes 12 SAS SSD Dell - solid state drive - 1.6 TB - SAS 12Gb/s. The storage server is running Linux SLES12SP1 #2 SMP and using NFSv3 Linux server. A second PowerEdge R630 is used in an Active-Passive mode as a failover server. The PowerEdge R640 is configured with 12 Dell Enterprise-class 2.5", 1.6TB Solid State Drives, Serial Attached SCSI 12Gb/s drive technology and 4 10GbE Ethernet networking.

Memory Notes

Each PowerEdge R630 storage controller has main memory that is used for the operating system and for caching filesystem data. It uses a 160GiB partition of one SSD device to provide stable storage for writes that have not yet been written to disk.

Stable Storage

Each PowerEdge R630 storage node is equipped with a nvram journal that stores writes to the local SSD disks. The nvram mirror data to a partition of SSD flash device in the event of power-loss.

Solution Under Test Configuration Notes

The system under test consisted of 2 PowerEdge R630 storage nodes, 1U each, configured as Active-StdBy, connected by 4 10 GbE ports of a 4 ports NIC. Each storage node was configured with 4 10GbE network interfaces connected to a 10GbE switch. There were 24 load generating clients, each connected to the same PowerConnect 8024 Ethernet switch as the PowerEdge R630 storage nodes.

Other Solution Notes

None

Dataflow

Each load generating client mounted all the 8 file systems using NFSv3. Because there is a single active storage node, all the clients mounted all 8 file systems from the storage node. 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 file system. This ensured an even distribution of load over the network and among the 8 file systems configured on the storage node.
