DELL R720xd服务器RAID的IOPS测试详解 - 摘要: 本文讲的是DELL R720xd服务器RAID的IOPS测试详解, 一、服务器配置 品牌:DELL 型号:PowerEdge R710 CPU:2 * Intel(R) Xeon(R) CPU E5-2670 @ 2.60GHz 内存:24 * 8G 阵列卡:PERC 6/i 硬盘:8 * 300

一、服务器配置

品牌:DELL
型号:PowerEdge R710
CPU:2 * Intel(R) Xeon(R) CPU E5-2670 @ 2.60GHz
内存:24 * 8G
阵列卡:PERC 6/i
硬盘:8 * 300G 15k SAS + 4*4T 7.2k
系统:Centos 7

二、开始测试

1.1、6块盘做RAID 0(300G 15k SAS)
