Sun SSD Server Platform Bandwidth and IOPS (Speeds & Feeds)
By Leah Schoeb on Jun 25, 2009
The Sun SSD (32 GB SATA 2.5" SSD) is the world's first enterprise-quality, open-standard Flash design. Built to an industry-standard JEDEC form factor, the module is being made available to developers and the OpenSolaris Storage community to foster Flash innovation. The Sun SSD delivers unprecedented IO performance, saves on power, space, and cooling, and will enable new levels of server optimization and datacenter efficiencies.
- The Sun SSD demonstrated performance of 98K 4K random read IOPS on a Sun Fire X4450 server running the Solaris operating system.
Solaris 10 Results
|Random Read (4K)||98.4K IOPS||71.5K IOPS|
|Random Write (4K)||31.8K IOPS||14.4K IOPS|
|50-50 Read/Write (4K)||14.9K IOPS||15.7K IOPS|
|Sequential Read (MB/sec)||764 MB/sec||1012 MB/sec|
|Sequential Write (MB/sec)||376 MB/sec||531 MB/sec|
Results and Configuration Summary
- 4 x Sun SSD
32 GB SATA 2.5" SSD (24 GB usable)
2.5in drive form factor
- Sun SPARC Enterprise T5240 - 4 internal drive slots used (LSI driver)
Sun Fire X4450 - 4 internal drive slots used (LSI driver)
OpenSolaris 2009.06 or Solaris 10 10/09 (MPT driver enhancements)
Sun measured a wide variety of IO performance metrics on the Sun SSD using Vdbench 5.0 measuring 100% Random Read, 100% Random Write, 100% Sequential Read, 100% Sequential Write, and 50-50 read/write. This demonstrates the maximum performance and throughput of the storage system.
###Random Read and writes tests varying transfer size
###Sequential read and Write tests varying transfer size
Key Points and Best Practices
- All measurements were done with the internal HBA and not the internal RAID.
- Vdbench is publicly available for download at: http://vdbench.org
Sun SSD delivered 71.5K 4K read IOPS and 1012 MB/sec sequential read. Vdbench 5.0 (http://vdbench.org) was used for the test. Results as of June 17, 2009.
