BENCHMARK #3 œ MACOS STRIPEOF 4-DRIVE STEELVINE FAST VOLUMES
A similar OS RAID stripe over four, four-drive fast SteelVine volumes produces results that are only 9% slower than the 20-drive OS
stripe or eight-way OS stripe of fast pairs. As expected, the four-way OS stripe of four-drive fast volumes required even less CPU than
the two-drive fast configuration using an average of 20% of available CPU during benchmark reads and writes with a peak CPU load of
about 25% .
CONCLUSION
Systems based on SteelVine processors such as the Sil4726 provide outstanding price/performance with more than 700MB/s read and
600MB/s write performance all while occupying only a single PCI-X slot in a PowerMac G5. SteelVine processor based systems
deliver this performance while consuming less CPU by using a combination of OS and hardware RAID 0 striping.
