• There are several ways to reporting snapshots. You can use PowerCLI, VRTools, or even vSphere Client itself. Today I will show you how to reporting by vRealize Operations Manager (vROps) 6.x. The benefit of  vROps reports is you can schedule it by sending email with PDF & CSV reports. I found a post discuss how to…


  • HPE SPP2016.04 is released. I usually test April version since it’s always stable than October or other earlier version.

  • I want to try make a remote control car by Raspberry Pi. The first question is how to power a portable Raspberry Pi? There are lot of solutions in internet. I want to find a simple, cheap and long battery life solution. Some articles introduced power bank but it overs $100 and only provides 5v output.…


  • 一直想要用树莓派做个遥控小车,最先碰到的问题是如何给移动的树莓派供电?网上有很多方案,想找一个简单、便宜、可以长时间供电的解决方案。有文章介绍用移动电源,但是价格都高于100美元并且只提供5v电力输出。我需要一个不但可以给树莓派供电,还可以给L298N至少供7v的电力系统。


  • Cisco UCS blade system is the best blade system I used so far. Whatever the hardware, software or support is perfect. I recommend leverage the system for primary system of virtualization. UCS blade system architecture is different with HP. I feel it more likes a network system. Fabric Interconnect (FI) modules exchange data between uplinks…


  • 思科UCS刀片系列是我至今用过最好的刀片系统。无论是硬件、软件还是技术支持都堪称完美。个人推荐在大型虚拟化机房里把思科UCS作为主要设备。思科UCS刀片系统的架构和惠普的完全不同,感觉更像是个网络设备。Fabric Interconnect (FI)模块负责上联口和内部各组件之间的数据交换、IOM负责各刀箱数据路由。架构看起来很复杂,但是在管理大型数据中心时非常强大。说到大型数据中心,比如有 上百个刀箱和刀片服务器,数据要经过FI、IOM、刀片等,问题可能发生在任何层面,大型虚拟化数据中心很难找到问题的根源。UCS Manager有提供类似思科网络交换机一样的计数器功能,可以显示每一个端口的计数情况,但是这个监控工具不会告诉你什么时间、在哪个层面发生了问题 。在测试NetApp存储性能监控组件之前我有幸测试了vRealize Operations Manager 6的Cisco UCS性能监控组件。该组建同样由Blue Medora开发。以下简单介绍一下,只是我的个人观点 。


  • NetApp released Virtual Storage Console (VSC) 6.1 for vCenter 6.0. The solution is only support vSphere Web Client now. I did some testing on my lab, faced a very special case.
