Gear6 Caching Appliance Delivers Over 872,000 I/O Operations Per Second

Gear6, a start-up based in Mountain View, California, reported breakthrough I/O performance results for large scale network-based caching designed for massive compute grid.



Gear6 said throughput testing of its CACHEfx appliance reached 872,291 IOPS with an average response time of 0.53 milliseconds and sustained bandwidth of 2.8GB per second. Bandwidth intensive testing achieved a sustained 5GB per second while delivering 162,292 IOPS.



The company's CACHEfx appliances attach to the network using standard Gigabit Ethernet or 10 Gigabit Ethernet, and support any NFS-based file system, including clustered file systems. Centralized storage caching extends the capabilities of existing compute clusters and storage systems without requiring changes to applications, file systems, or storage management software.



Load testing was conducted using an I/O load generator configured to drive a wide range of workloads. The throughput test simulated an IOPS- and latency-intensive workload characterized by many small-sized operations. This test consisted of 60 clients accessing data from the CACHEfx appliance with a 4KB block size. The bandwidth-intensive test modified the workload such that there were fewer larger-sized operations. This test consisted of 74 clients accessing data from the CACHEfx appliance with a 32KB block size.
