BestPerf: Performance & Best Practices

Significance of Results

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.

32 GB SATA 2.5" SSD (24 GB usable)
2.5in drive form factor

Servers:

Sun SPARC Enterprise T5240 - 4 internal drive slots used (LSI driver)
Sun Fire X4450 - 4 internal drive slots used (LSI driver)
Sun Fire X4440 - 4 internal drive slots used (LSI driver)

Vdbench 5.0

Benchmark Description

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.

Vdbench profile:

wd=wm_80dr,sd=sd*,readpct=0,rhpct=0,seekpct=100

rd=run4_rs_80dr,wd=rs_80dr
rd=run5_ws_80dr,wd=ws_80dr

Key Points and Best Practices

• All measurements were done with the internal HBA and not the internal RAID.
