The Isilon IQ5400S, built on Isilon's proven clustered storage technology-accelerates business and increases speed-to-market by providing ultra-fast primary storage for your mission critical, high transactional, and random access file-based applications. The S-Series combines the power of enterprise-class 15,000 RPM Serial Attached SCSI (SAS) drive technology, Quad-GbE front-end networking, dual quad-core Intel CPUs, a high-performance InfiniBand back-end, and up to 1.5 TB of globally coherent cache. The IQ5400S Storage System can scale out from a 3 node cluster to a 96 node cluster in a single filesystem.

Disks and Filesystems

Description Number of Disks Usable Size
450GB SAS 15k RPM Disk Drives 120 46.9 TB
Total 120 46.9 TB
Number of Filesystems 1
Total Exported Capacity 48.0 TB
Filesystem Type IFS
Filesystem Creation Options Default
Filesystem Config 9+1 Parity Protected
Fileset Size 5500.8 GB

Writes are striped across all 10 storage nodes with +1 parity protection to protect against either a single disk failure, or a single storage node failure.

Network Configuration

Item No Network Type Number of Ports Used Notes
1 Jumbo Frame Gigabit Ethernet 20 Integrated 10/100/1000 Ethernet controller

Network Configuration Notes

two gigabit ethernet network interfaces were configured on each storage node. The interfaces were configured to use jumbo frames (MTU size of 9000 bytes). All network interfaces were connected to a Force10 E1200 switch, which provided connectivity to the clients.

Benchmark Network

All switch ports were configured to allow Jumbo Frames (9000 MTU)

Grand Total Memory Gigabytes     165  

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. 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 10 IQ5400S storage nodes, 2U each, connected by DDR Infiniband. Each storage node provides 4 gigabit ethernet interfaces. for the purpose of this test, two of these interfaces were configured and connected to a gigabit ethernet 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 10 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
