0x01 ProLiant DL380 G6
在2015年的8月，我从淘宝买了一台服务器，本来是想学习虚拟化技术的，谁知这坑越踩越深，现在深陷在服务器里面不能自拔。以下是服务器配置：
- 型号：ProLiant DL380 G6
- CPU：Intel Xeon L5630 X2（每颗CPU4核心8线程，一共16线程）
- 内存：4GB DDR3 1066 ECC X8（一共32GB内存）
- RAID卡：HP P410i SAS RAID 256M缓存（组建RAID 10）
- 硬盘：300GB 10K 热插拔 2.5寸硬盘 X4(一共1TB，可用约500GB)
- 网口：1000M自适应网口 X2，100M iLO网口 X1
0x02 前面板
- UID按钮
- 状态灯
- 开关机按钮
- 两个USB2.0接口
- 一个VGA接口
- 网络、CPU、内存、散热风扇错误、信息提示灯。
- 旁边是硬盘，硬盘架子不是一样的，可是硬盘都是300GB 10K。
0x03 盖子背面 | 服务器说明书
服务器都会在盖子背面贴上安装说明书，大都是关于内存与CPU拆卸和安装的信息。我想应该是大家买到服务器后，说明书一般不会长时间保留的原因。
0x04 磁盘阵列
它可以承载最多8块硬盘，可惜我现在只有4块。这服务器主要用作运算，我并不打算继续添加硬盘。反而计划增添一台存储服务器，用于数据的存储。当然，存储服务器也不会使用RAID10，肯定要选择更安全的阵列。
0x05 散热风扇
6个热插拔散热风扇。免工具拆卸，方便服务器在运转的时候更换坏掉的风扇。当拆掉一个后，其他5个会全速运转，声音大得无法形容。当拆掉2个，必须在规定时间内装回，要不然服务会停机！
