Windows Server 2016 技术预览3内核模式 - 远程管理技巧

微软刚刚发布了Windows Server 2016的技术预览3。新版本中有很多增强,看起来微软的软件定义的数据中心正在赶上VMware。一个稳定的虚拟层是软件定义数据中心的前提,但这是微 软的软肋。你不得不不停地打各种补丁和重启服务器,甚至有些企业有定期的重启计划。微软在Windows Server 2008 的时候引入了核心模式并且在Windows Server 2012 R2中得到增强。但是Windows Server 2012 R2瞄准的是中小企业市场,我不认为他们会使用核心模式,因为复杂度要提升很多。

How to call customized vRealize Orchestrator workflows in vRealize Automation Center

You almost can do everything as long as vRealize Automation Center (aka vRA) and vRealize Orchestrator (aka vRO) are integrated. I think that's the hard part if you are newbie like me. After reading lot of articles, I learned how it works. Following is my experience, please let me know if you see anything wrong. 把vRA和vRO结合在一起几乎可以做任何事情。如果你和我一样是新手,和uijuede 得整合这块比较难,最近阅读了一些这方面的文章,算是有所了解了。以下是我的见解,如果有问题留言给我。

Core mode of Windows Server 2016 TP3 - Remote Management Tip

Microsoft just released technical preview 3 of Windows Server 2016, it's catching up VMware on SDDC. I can see a lot of enhancement in the new version. A stable hypervisor is  prerequisite of SDDC but it's weakness of Microsoft. You have to patch and reboot frequently, some organizations even have regular reboot schedules. Microsoft introduced core mode on Windows Server 2008, it much enhanced on Windows Server 2012 R2. But Windows Server 2012 R2 aims to SBM. I didn't think SBM organizations really need that if you compare operation complexity of core mode with GUI.

PCPU locked up on Cisco UCS

[caption id="attachment_569" align="alignnone" width="300"] Error message of the PSOD[/caption] ESXi 5.5 Update 2 is stable version, but I got PSOD on one UCS blade few days ago. It scared me since there was a big bug when I upgraded ESXi from 5.1 to 5.5 Update 1 last year(See detail ESXi 5.5 and Emulex OneConnect 10Gb NIC ), it lead to dozen virtual  machines crashed over and over again.I bet I'm gonna to die if it happens again. :-) ESXi 5.5 Update 2 算得上比较稳定的版本了,但前几天遇到一台紫屏,差点儿吓尿了。半年前从ESXi 5.1升级到ESXi5.5 Update 1时候遇到个大BUG(详情见我的文章ESXi 5.5 and Emulex OneConnect 10Gb NIC),搞得几十台几十台机器挂,这次升级再来一次估计职业生涯就此结束了。
