挖坑 SmartOS

<Category: 虚拟化> 查看评论

在家弄了一台gen8服务器作为自己倒腾用,gen8便宜够用,最多只能挂4块盘+光驱位,内存一次到位16GB,CPU一步到位,虚拟化方案最后选了 ,主要原因:1.没有折腾过;2.VMwareESXi 太重,性能一般;3.Docker 不适合;4.微软那一套的已弃坑;5.单独一个系统再加 KVM、XEN 管理不方便;6. 号称性能最高;7. 下的 Zones、DTrace、KVM 、ZFS 都很帅!轻量级,microSD 卡启动,启动文件随便坏,系统layout做在 ZFS 里面,不受外部影响;ZFS 的软件散列机制比 RAID 卡更好用(没几块盘, 没有强悍RAID卡的情况下,gen8自带 RAID 卡实在太弱,加盘也不方便)

个人觉得 SmartOS 的虚拟化方案对比 Docker 更优秀,只不过由于是 Unix,没有 Linux 下用户多,Joyent 公司确实厉害,除了 SmartOS,NodeJS 也是他们厂的,SmartOS 管理虚拟机的时候,刚开始折腾死我了,没有文档没有用户确实解决问题很麻烦,搜索都没有几条答案,不过折腾完了之后发现还是超级好用的。

贴一下资料方便自己速查:

SmartOS 下LXZones系统的软件限制(KVM 安装的系统没有),好大坑,iptables 不支持!
