From Ricardo.M.Correia at Sun.COM Tue Nov 13 11:48:38 2007 From: Ricardo.M.Correia at Sun.COM (Ricardo Correia) Date: Tue, 13 Nov 2007 11:48:38 +0000 Subject: [Lustre-announce] ZFS/DMU benchmarks In-Reply-To: References: Message-ID: <47398F16.5000504@Sun.COM> Hi everyone, Here are some current ZFS/DMU benchmark results that might be of interest to you. These results were obtained on a Sunfire x4500 with these specifications: - 2 dual-core AMD Opteron processors - 16 GB main memory - 48 SATA II HDD (7200 RPM, 500 GB each) - Solaris 10 update 3 - Userspace DMU from OpenSolaris build 74 The tool used in this particular benchmark was PIOS, which simulates a parallel I/O load typically experienced by an OSS. Since PIOS links directly with the DMU, it should give a good estimation of the maximum throughput of the userspace DMU-OSS. For comparison, you can also see the results of running the same PIOS benchmark with normal POSIX I/O on the Solaris 10u3 ZFS implementation. See the attached PDF for the results. First page provides PIOS throughput information on striped pools with 10, 24 and 46 disks. uDMU outperforms kernel ZFS with 10 disks, however, the kernel ZFS implementation scales better to 24 and 46 disks. Surprisingly enough, disabling checksums has a negative impact on the throughput with a 10-disk striped pool. This impact can be attributed to the differences in the uDMU IO pipeline which are probably causing the IOs to not being parallelized when checksumming is disabled. This issue, however, should not be hard to fix. Second page shows the results of running PIOS on RAID-Z, RAID-Z2 and mirrored pools. In these configurations, the kernel ZFS currently has a better throughput than the userspace DMU. These results were obtained with only minimal tuning of the DMU (setting a maximum cache size and increasing the number of I/O threads). Work is already underway to improve the performance of the DMU and we expect to see better throughput in the coming months.
