If you are multi-language IT Pro you may want to show articles in multiple languages just like me. I use Polylang in my blog to switch English and Chinese version. I used to add “Language Switcher” tag in my articles. It’s manual process that I had to remember the tag in somewhere, copy and past it to articles when I was writing. It’s frustration to repeat it in every article. Another problem was I have to add “Read More” tag in each article before I add “Language Switcher” tag. That’s because each post shows a switcher in home page if I don’t do that. It confuses Polylang which URL each article should goes. I want to find a perfect way to fix this problem! Here we go…
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 reports by vROps. But it requests modify policy, it may impacts global calculation. What if your teams request different criteria for reports?
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. I need some thing can provide not only 5v power for Raspberry Pi, but also more than 7v for L298N.
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 and internal components. IOMs on each chassis controls data routing. Architecture is complicate, but it’s powerful to manage large datacenter. Talking about large datacenter, you may have hundred chassis or blades. Data goes through FIs, IOMs and blades, you could see issues on any layer. It’s hard to find out where exactly the problem is. UCS Manager provides statistics for ports just like how Cisco does on network switches. You can show statistics of a particular port. But it doesn’t tell you when and which layer it happened. I tested Cisco UCS adapter for vRealize Operation Manager before I reviewed NetApp adapter for vRealize Operation Manager. It’s developed by same company Blue Medora. I’d like to introduce few of this product, it’s just my personal review.
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.
Today I got a strange problem about share folder. Some virtual machines cannot access network share path. It gave me Unspecified Error 0x80004005 when I opened a share folder on explorer. It gave me The network path was not found 0x80070035 when I opened same share folder by clicking Start – Run.
vRealize Operation Manager 6 (aka vROps) is new generation of vCenter Operation Manager. I started to use vCenter Operation Manager since version 1.0. I like the idea of self-learning and dynamic threshold. But the product only monitors virtualization layer. It would be perfect if it’s able to monitor under layer storage. In large vSphere environment, virtual machines share IO capacity of datastores. If few virtual machines running high disk IO it may lead to other virtual machines get performance degrading in same storage. Think about you have 100 datastores come from a NetApp filer, and 300 virtual machines running on its. One user says their virtual machine is slow but no workload from applications end. It hard to say where the latency comes from because multiple virtual machines may share same datastore, multiple LUNs share same aggregate, and maybe same physical disks. vCenter Operation Manager provided NetApp Adapter for 5.x few years ago. But the problem was it’s too hard to associate storage objects with vSphere datastore objects.
vRealize Automation 7 (vRA 7) has lot of enhancements and changes compare with vRA 6. There are plenty of introductions available in internet. The initial configuration is different with vRA 6. I’m going to share my experience. You can easily build up LAB or POC by following this post.
You may see that error message “To view this page ensure that Adobe Flash Player version 11.5.0 or greater is installed. ” when you open vSphere Web Client 6.0 on IE 11 on Windows 8.1. The login fields still visible, but the page go to blank after you login.
