DDN SFA7700存储系统测试报告

1、DDN SFA7700存储系统测试报告测试环境1套DDN SFA7700存储盘阵：1台DDN SFA7700主盘柜，2个SS8460扩展柜；SFA7700有2个控制器，每个控制器有2个56Gb/s FQR Infiniband接口与QDR IB交换机相连；228块 4TB 7200转硬盘；共计22个 Pools(8+2 Raid6)测试及IO节点基本配置：共计2台IO节点；每台IO节点240 core（Intel(R) Xeon(R) CPU E5-4640 0 2.40GHz）每台IO节点3.8TB Memory每台IO节点通过两个40GB QDR HCA与IB交换机相连文件系统GPFS 3

2、.5.0.7测试链路拓扑：存储系统性能测试：测试工具：DD性能测试主要是用于模仿用户串行作业工作模式。DD用于复制，从if读出，写到of。if=/dev/zero不产生IO，因此可以用来测试纯写速度。测试命令：本节点测试：dd if=/dev/zero of=/mnt/ddnfs/test/swap.1 bs=1M count=30000 &双节点测试：dd if=/dev/zero of=/mnt/ddnfs/test/swap.1 bs=1M count=30000 &ssh 10.149.255.201 dd if=/dev/zero of=/mnt/ddnfs/test/swap.11
