原文来自于资深市场经理Subbu Krishnamurthy发表于RedHat Magazine 的系列文章. 我做适用性摘选, 涉及到Red Hat® Global File System (GFS),Red Hat Cluster Suite (CS)等.
Red Hat Enterprise Linux® 4版本附加中为Linux企业应用而做的 Red Hat Cluster Suite (CS),Red Hat® Global File System (GFS),Distributed Lock Manager (DLM) 套件在Red Hat Enterprise Linux® 4在大部分人从网络下载到的四张CD中是找不到的， 如为学习之用大家也可从RedHat RHN中得到或使用CentOS .
GFS (is not Google FS(GFS)和CS 解决了一些关键应用中的高可用性与数据共享存储难题. 虽然商业解决方案如Oracle,HP等也有类似的HA解决方案，也有NFS的简洁操作Shared Storaged方式；但从花费及效率上而言都不及RedHat 的这一套整体解决套件( 毕竟你用的是它的OS嘛).

月光明亮， 照得恋人凄凉；
再犯的错误怎可能换的另一个胸膛的温暖, 爱的寂想， 破镜重圆是天方妄想.
