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.

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
====================
None
Dataflow
========
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.
