The Isilon S210, built on Isilon's proven scale-out storage platform, provides enterprises with industry-leading IO/s from a single file system, single volume. The S210 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 OneFS operating system enables enterprises to scale storage seamlessly with their environment and application while maintaining flat operational expenses. The S210 is based on enterprise-class 2.5" 10,000 RPM Serial Attached SCSI drive technology, 10GbE Ethernet networking, and a high performance Infiniband back-end. The S210 scales from as few as 3 nodes to as a high as 144 nodes in a single file system, single volume.

SSD Policy set to metadata-write acceleration, L3 Cache disabled, File data is striped across all 14 nodes using at most 2 drives per node for a given protection group, thus protecting against 2 drives failures or one full node failure

Network Configuration

Item No Network Type Number of Ports Used Notes
1 Single 10GbE interface configured on each node, 1500 MTU 14 10GbE SFP+ PCIe NIC

Network Configuration Notes

All nodes and clients are connected to an Arista Networks DCS-7150S-64-CL

Benchmark Network

Each load generator and each S210 storage node was configured with a single 10GbE, 1500 MTU connection to the Arista Switch.

1 28 CPU Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz Network, NFS, Filesystem, Device Drivers

Processing Element Notes

Each storage node has 2 physical processors with 6 cores and SMT enabled


Description Size in GB Number of Instances Total GB Nonvolatile
Storage Node System Memory 256 14 3584 V
Storage Node Integrated NVRAM module with Vault-to-Flash 2 14 28 NV
Grand Total Memory Gigabytes     3612  

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 storage 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.

System Under Test Configuration Notes

The system under test consisted of 14 S210 storage nodes, 2U each, connected by QDR Infiniband. Each storage node was configured with a single 10GbE network interface connected to a 10GbE switch.

Load Generator Configuration Notes

All clients were connected to a single filesystem through all storage nodes

Uniform Access Rule Compliance

Each load-generating client hosted 192 processes. The assignment of processes to network interfaces was done such that they were evenly divided across all network paths to the storage controllers. The filesystem data was striped evenly across all disks and storage nodes
