GlusterFS 1.3.pre0-BENKI Aggregated I/O Benchmark on 16 brick server and 64 clients over Infiniband Verbs transport. Multiple 'dd' of varying blocks are read and written from multiple clients simultaneously.
[edit]
GlusterFS Brick Config (16 bricks)
- Processor - Dual Intel(R) Xeon(R) CPU 5160 @ 3.00GHz
- RAM - 8GB FB-DIMM
- Linux Kernel - 2.6.18-5+em64t+ofed111 (Debian)
- Disk: SATA-II 500GB
- Mellanox MHGS18-XT/S Infiniband HCA
[edit]
Client Config (64 clients)
- Processor - Single Intel(R) Pentium(R) D CPU 3.40GHz
- RAM - 4GB DDR2 (533 MHz)
- Linux Kernel - 2.6.18-5+em64t+ofed111 (Debian)
- Mellanox MHGS18-XT/S Infiniband HCA
[edit]
Interconnect Switch
- Voltaire port Infiniband Switch (14U)
[edit]
Aggregated Throughput of 16 bricks Vs Number of Clients (using ib-verbs)
Note that transfer rate is in BYTES per second (multiply by 8 for BITS per second).
Notes:
- Peak aggregated read throughput was 130Gbps.
- ib-verbs transport driver is about 30% faster than ib-sdp transport driver.
- After a particular threshold, write performance plateaus because of disk I/O bottleneck. System memory greater than the peak load will ensure best possible performance.
