The Isilon S200, built on Isilon's proven scale-out storage platform, provides enterprises with industry-leading IO/s from a single file system, single volume. The S200 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 S200 is based on enterprise-class 2.5" 10,000 RPM Serial Attached SCSI drive technology, 10GbE Ethernet networking, dual quad-core Intel CPUs, a high performance Infiniband back-end, and up to 13.8 TB of globally coherent cache. The S200 scales from as few as 3 nodes to as a high as 144 nodes in a single file system, single volume.

Network Configuration

Item No Network Type Number of Ports Used Notes
1 10GbE with Jumbo Frames 28 10GbE SFP+ PCIe NIC

Network Configuration Notes

The Brocade MLXe-32 configured with 232 wire speed 10GbE ports delivering full utilization of all links for optimum network utilization and instantaneous link or node failover. Non-stop networking is further achieved through hitless failover and software upgrades, and fully redundant hardware components. The configuration provided a single VLAN, with STP disabled and Jumbo Frame support enabled.

Benchmark Network

Each load generator and each S200 storage node was configured with a single 10GbE, 9000 MTU connection to the MLXe-32.

Storage Node System Memory 48 28 1344 V
Storage Node Integrated NVRAM module 0.5 28 14 NV
Grand Total Memory Gigabytes     1358  

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 is protected by 2 batteries, providing stable storage for more than 72 hours. In the event of double battery failure the node will no longer write to the local disks, but continues to write to the remaining storage nodes.

System Under Test Configuration Notes

The system under test consisted of 28 S200 storage nodes, 2U each, connected by DDR 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 16 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.
