Report snapshots older than X days in vROps

by

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?

Power Raspberry Pi by Portable Chargers

by

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.

vRealize Operations Management Pack for Cisco UCS Review

by

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 Management Package for vRealize Operation Manager 6

by

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.
