操作系统是centos6.3
DELL PowerEdge R720 （2U机架式服务器）
4根8GB RDIMM, 1600MT/s,
3块300GB SAS热插拔硬盘 raid 5
服务器上面跑的是mysql数据库，用了两个月没啥问题，8月22号早上突然死机，重启后部分表损坏(修复后正常了，有一个sys_log表直接无法修复，使用备份后可以使用)
让dell售后的人看了下，就电源报错，说是代理商更换了电源，这个是dest软件的截图

内容有点多, 没有细看, 个人有如下建议.
1. R720 应该是 四通道内存的. 最佳的配置应该是每CPU 4条内存. 楼主的机器一共4条, 如果有两个CPU的话, 性能不会太好.
2. 无法修复的表损坏, 如果硬盘本身在没坏的话. 应该是mysql的cache在flush之前机器crash导致的. 这个问题mysql解决不了. 因为它只有一个 redo log, 好象, 还是要配置才行的.
3. 从DESET log看, 你的机器一直只有一个电源, 或者说有一个电源是坏的(或者没插线).

多谢楼上的兄弟解答
1.服务器内存基本够用，经过一段时间的观察，基本上用不到swap，CPU占用率一般不会超过20%
3.其实电源报警与否我不太关心，这对硬件和应用没有太大的影响
2.这点才是最致命的，跑在上面的数据库应用无法访问，重启以后被损坏，就在找这方面的原因
从dell的硬件检测软件来看基本可以排除硬件的问题，现在在想是操作系统的问题呢？还是兼容性问题，或者是由某软件导致的问题

我很奇怪你不关心硬件报警. 你的直接原因就是因为电源问题导致down机.
如果你觉得软件可以解决硬件down的问题, 那你可以研究一下. 有结果告诉我一下.
我替你去BS那些买双电源, RAID卡, mirror内存的人.

&&dell的备用电源线被拔掉了啊，我都插了俩条电源线，虽然不是必须的，好歹是个冗余嘛，而且，有点强迫症，老是看着机箱后面的黄灯闪，别扭

这个前面忘了说明，机器不是dell厂家直销的，被代理商更换了CPU、硬盘、RAID卡，还拆掉了一个电源
也就是说这个机器是单电源，应该不是电源掉电导致的系统挂掉，因为当时我去机房看了，电源并没有关闭，插上显示器显示的是乱码
当时ctrl+alt+delete重启了机器，后面mysql表损坏

感谢 7楼的 dengbao2001 指出问题
也感谢 q1208c 一直热心关注
问题应该出在了兼容性上，CPU和centos内核不兼容
