Useful links for Microsoft Azure

By

As you might have noticed Microsoft Azure is full of features, dashboards, documentation and more. Personally I think they are doing a very well job on that part. In my days working with Azure I have collected some links that might be useful to you. Below you find a few examples:  [Read more…]

SkyKick Cloud Backup (for Office 365)

By

I recently had the opportunity to implement a PoC (Proof-of-Concept) of SkyKick Cloud Backup for a customer. SkyKick Cloud Backup is an online backup service for Office 365. My experience so far; it is an absolute winner! The initial configuration took me no more than 5 minutes. After a backup is made; doing a single item restore is done in seconds!

So if you are looking for a backup solution for your Office 365 subscription; this is one of these online services that I can highly recommend. One more reason for me to share what it has to offer. I will also tell you how to get it, since this service is only available through Microsoft Partners. [Read more…]

My first FlexPod! (Part 6 – System Center)

By

This is part 6 and also the last part of the following blog series:

If you haven’t read the previous part, then I recommend you read them. On the other hand this will be a short one, because there is not that much to tell. Although the title of this blog is about System Center I want to show you three topics.

Partner Ecosystem Software:

Cisco has a partner ecosystem with software for management of Cisco UCS. When you go to the Cisco support page you can download a lot of tools/add-ins. [Read more…]

My first FlexPod! (Part 5 – Hyper-V Cluster)

By

This is part 5 of the following blog series:

I hope part 1, 2, 3 and 4 where informative to you. In this part it is time to talk about an actual Hyper-V Cluster on UCS Blade Servers. Hosting a Hyper-V Cluster on UCS is not rocket science. The deployment is just as straightforward as with other brands. The only difference is that you are (more) flexible with your network configuration and you have the benefits from stateless computing, if that is what you want.

In our case we had eight physical UCS B200 M3 Blade Servers available as specified in part 2. When you have pre-configured UCS Manager with all pools and policies that are required, you are ready to create a Server Profile. You can then assign the new Server Profile to a physical server (equipment), boot it and begin installing the Operating System. [Read more…]

My first FlexPod! (Part 4 – Quality of Services)

By

This is part 4 of the following blog series:

Quality of Services:

I hope you enjoyed reading part 1, 2 and 3. As explained Cisco UCS is a converged infrastructure. A converged infrastructure uses less cabling and allows you to configure vNIC’s and vHBA’s as an abstraction layer on top of the physical infrastructure. This offers flexibility and has some benefits. It also adds an important requirement, which is QoS (Quality of Services). Without QoS, any type of traffic could saturate all available bandwidth resulting in slow network or storage performance. Which could potentially make your compute platform unstable. It is important that each type of traffic can consume as much bandwidth as possible when needed, but when the network gets congested each type of traffic gets a fare share of bandwidth, shaped by a pre-defined weight (%).

The nice thing is, Cisco UCS fully supports QoS. In fact, it is an absolute requirement which is easy to configure. QoS is not only used for traffic shaping, it is also used to handle certain type of traffic differently. Like storage traffic (especially Fiber Channel traffic) needs to be lossless (without packet drops). And you might want certain type of traffic (like iSCSI traffic) to use a different MTU packet size (e.g. Jumbo Frames with MTU 9000).

With this blog I am not going to explain QoS in technical detail. I will give you some links to technical resources that were useful to me. And I will explain what you can and need to configure in UCS Manager. [Read more…]
