Using the SPC Benchmark-1 to determine price-performance ratios for a number of storage systems, the benchmark delivered results that demonstrate a 1.9 X advantage for the Sun Storage 6180 (8Gb) array over the IBM DS5020, reported a Sun BestPerf blog. In another blog entry, testing of the same storage arrays on the SPC Benchmark-2 produced some interesting price-performance results as well.

The power to achieve better performance with fewer drives - lowering acquisition, support and operational costs - is what Sun proposes the Sun Storage 6180 Array offers customers. It also scales and integrates seamlessly all the way up to the flagship Sun Storage 6780 Array. Offering redundant components, the Sun Storage 6180 Array provides automated I/O path failover, and extensive online configuration, reconfiguration and maintenance capabilities.

The Sun Storage 6180 Array is a high-performance, enterprise-class, full 8 Gigabit per second (Gb/sec) I/O Fibre Channel solution with backend loop speeds of 2 or 4 Gb/sec. It is modular, rackmountable, and scalable from a single dual-controller tray (1x1) configuration to a maximum configuration of 1x7 with six additional CSM200 expansion trays behind one controller tray. Sun reports that this new array delivers 50% more performance than Sun's previous generation, and over 70% better price/performance than the IBM DS5020.

RAID 6 is the clear choice for data storage needs in the eyes of Said A. Syed, whose whitepaper "Using RAID 6 for Increased Reliability and Performance: Sun Storage 2500 Series, 6140, 6580 and 6780 Arrays" champions that algorithm over RAID 5 and RAID 1+0 for its ability to overcome the shortcomings of both.
