BeeGFS常用于高性能计算中的分布式文件存储，其对巨量小文件的支持相比于其他大多数文件系统而言，要好太多，这里介绍搭建的详细过程。一共使用3台服务器，一个磁盘分成两个区（分别用于元数据和数据存储），两个网卡（一个管理网，一个存储网）。
网络配置
网络分配
管理网络用于SSH登录等功能，都是千兆口，存储网络用于数据传输，为双万兆口Mode 6绑定。
| 主机名 | 管理网络 | 存储网络 | 服务部署说明 |
|---|---|---|---|
| sacd01 | 172.29.201.125 | 172.29.39.125 | mgmt，meta(2)，storage(401,402)，client |
| sacd02 | 172.29.201.126 | 172.29.39.126 | meta(3)，storage(501,502)，client |
| sacd03 | 172.29.201.133 | 172.29.39.113 | client |
下面的配置以sacd01为例进行说明。
DNS和主机名
sacd01 $ cat /etc/hosts 172.29.201.125 sacd01 172.29.201.126 sacd02 172.29.201.133 sacd03 sacd01 $ hostname sacd01 sacd01 $ cat /etc/hostname sacd01
网卡绑定

磁盘格式化
元数据分区使用

存储分区使
用XFS文件系统：
$ mkfs.xfs /dev/sdb2 meta-data=/dev/sdb2 isize=512 agcount=4, agsize=134217728 blks = sectsz=4096 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=536870912, imaxpct=5 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=262144, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0
