    你别笑,这是真实系统上测试出来的结果,存储系统的瓶颈问题越来越让人头疼了。

直接换12g的sas外加16g的fc 肯定快 还不行直接上并行文件系统 鸟语咋拼忘记了;P

    机械盘IOPS太低了。

硬盘啥配置?

    我觉得这个数据不一定准,最好拿个10多G的文件试试,让copy过程持续一段时间看看。
6GB SAS盘有几块?10000转还是15000转? raid怎么做的?

n块盘做raid50 数据自然不一样的;P

look一下

The IBM High IOPS SSD PCIe Adapters provide a new generation of ultra-high-performance storage based on solid state device technology for System x and BladeCenter. These adapters are alternatives to disk drives and are available in several sizes, from 160 GB to 1.2 TB. Designed for high-performance servers and computing appliances, these adapters deliver throughput of up to 300,000 I/O operations per second (IOPS), while providing the added benefits of lower power, cooling, and management overhead, and a smaller storage footprint.
