"Blogging is not writing, it's just graffiti with punctuation." Print E-mail

As everyone knows, the Top 25 virtualization blog voting machine is now open for business. This is NOT another "vote for me" post. I don't want to act like a selfish single child who needs more attention. Instead, this post is to encourage you to just go vote. More and more virtualization blogs are popping up everyday and these individuals put in a lot of work into sharing their knowledge with the world. Bloggers spend more time than you would think whiteboarding ideas or taking tons of screenshots to show you step by steps to spark your interests. It's almost a second job to many.

 

There is a great quote from the movie Contagion that i find amusing "Blogging is not writing, it's just graffiti with punctuation." There are so many blogs out there that it's very hard to find the few golden nuggets out of the mess written on the walls. The best blogs are consistently the best because they have the greatest content and make it amusing and fun for their readers. You only get 10 votes, so sort through the 100+ blogs, and choose the ones that consistently bring you back to want and read more. It means a lot to get votes from readers. I always love reading the emails that start with "Hey Kenny, i was reading your blog and..."

Virtual Machines Exhibit Poor CPU Performance in vCloud Director Print E-mail
Written by Kendrick Coleman

Someone call the n00b patrol because this one should have been a no-brainer. I was working with a customer today and their default image inside of vCloud Director is a Windows 2008 R2 VM with 1vCPU and 4GB of RAM. Whenever they deployed a new VM from vCloud Director, it would take approximately 45 minutes to complete the entire sysprep process and boot up. After that 45 minute process, when they tried to use that VM, it was almost unbearable through the web UI because it was so slow. The CPU performance was just outright horrible.

 

After a few quick conversations, I did a bit of troubleshooting to narrow it down to a vCloud problem. I used the same exact image and deployed it from template on a blade used for vCloud resources. It also deployed on the same datastore so we could cancel out the hardware issue. Sysprep ran, and the VM was created and ready for use after 4-7 minutes. So it was definitely a problem in vCloud.

 

I opened up the vSphere Client to the vCloud vCenter and started looking at the VM that was spun up from vCloud Director under the resources tab. This should have been as clear as day to point out. The VM has a limit set on it of 260MHz.

Nexus 1000v On A Network With No VLANs Print E-mail

So the title is technically inaccurate. Everything has to traverse a VLAN, and if no VLAN is specified, then you're riding on VLAN 1.

 

I volunteered to build some Hands On Labs for our technical sales folks and I was in charge of creating the Nexus 1000v Lab. After battling a few quirks for about 7 hours, I was finally able to get everything functioning correctly. The networking piece didn't take 7 hours, but the lab was convoluted enough that I will save you from reading about it.

 

The lab consisted of running the latest software:

  • vCenter 5 Build 455964
  • 2x Nested ESXi Servers running 5.0 Build 504890
  • Nexus 1000v VSM 4.2(1) SV1(4a)
  • Nexus 1000v VEM 201108271-BG

How To Setup Riverbed Stingray Traffic Manager / Zeus Load Balancer for VMware vCloud or View Print E-mail
Written by Kendrick Coleman   
Wednesday, 04 January 2012 18:27

Recently, my virtual Zeus load balancer wouldn't boot up properly so I figured I would just rebuild it. Come to find out, I couldn't remember everything I did to get it working properly so now I'm documenting it for anyone else that may want to do this. Zeus Load balancer is a great free utility that was recently acquired by Riverbed Technologies and is now labeled as the Riverbed Stingray Traffic Manager. It's a good product for home labbers because it will do SSL HTTPS load balancing which works great for vCloud or View testing. Check out Chris Colotti's post Load Balancing Considerations for vCloud.

 

To get the product, sign up for a Zeus/Riverbed Developer Account. You will be emailed a username and password and will get access to the downloads area and see these files below: Add a comment

How To Deploy a VM or vApp from vCloud Director Print E-mail
Written by Kendrick Coleman

I got a request internally for a simple step-by-step of how to deploy a vApp or VM from vCloud Director because the IT group has no experience with vCloud. I toiled on putting this blog article up because the simplicity is just, well, simple. Thanks to a few twitterati (@P2Vme, @angeloluciani, @jmichelmetz, and @mtellin) for making me do it anyway. here we go

 

Before you begin, you need to know where to go. vCloud has a few different portals but there is going to be one defined for your particular organization. For instance, my vCloud Director instance rests at https://vcloud.kendrickcoleman.c0m/cloud/. This webaddress is for administrator access. When you create a new Organization inside vCloud Director such as Developer, you can create a new logon portal that can be accessed at https://vcloud.kendrickcoleman.c0m/cloud/org/Developer.

Go to Interactive 3D Vblocks Now In The App Store

 

So this blog post is really just one of the cool things that have come out of VCE's marketing department. I saw a tweet from @treylayton that pointed to VCE's new KAON demo located here http://www.vce.com/vblock/300/model/. You may think that's cool, but it gets even better. That website will render an interactive Vblock of the basic completed Vblock.

 

This following tool takes that interactive demo 10x further. It's available to anyone within VCE, EMC, Cisco, or VMware. I will see what I can do for anyone that works for a VCE Partner. Speak up if you want it in the comments and I'll take it up the chain. You can use the demo I'm going to show below by following these simple instructions:

  1. Download the Kaon v-Stream app for iPad from the iTunes appstore (it’s free)
  2. Install the App on your iPad
  3. Go to http://portals.v-central.com/vce
  4. Enter your VCE, Cisco, EMC or VMware company email address and a password
  5. Check your email for a message from This e-mail address is being protected from spambots. You need JavaScript enabled to view it to confirm your address
  6. Open the Kaon v-Stream App on your iPad
  7. Once logged in, select the Vblock 300 Demo to begin streaming to your iPad (note: you must be online in order to stream the demo)

VCE Releases the Vblock Version Tool Print E-mail
Written by Kendrick Coleman   
Thursday, 22 December 2011 11:34

I'm amazed every day by the amount of effort people in VCE contribute. VCE has that VMware Labs feel to it. If you see a hole that needs to be filled, go fill it. Do you have an idea that you want to make into a project, run with it. It's innovation and ideas that keep things moving forward.

 

Today, VCE released a new tool for its customers called the Vblock Version Tool. This program will allow a partner/customer to gather all the required firmware/software level versions on their Vblock and compare it against the Official Release Matrix.  If you don't know, the Official Release Matrix is a chart/martix/pdf that gets updated about once or twice a quarter (depending on how many and what types of firmwares are released) and plays into VCE's strategy of a Pre-Integrated & Pre-Tested Product. Every component in the Vblock (Storage, UCS, VMware, MDS, Nexus, 1000v, PowerPath V/E, UIM, etc) all have some sort of firmware or software level tied to them. VCE's goal is to release a product that adheres to specific firmware/software levels to ensure complete interoperability and superior performance. The Official Release Matrix contains all the software/firmware levels for specific Vblock models and can be found internally on VCE Portal or partners can get it on VCE Partner Portal.

 

The Vblock Version Tool shows the continued effort VCE makes in building the industry's ONLY integrated stack with true differentiating characteristics.  VCE is continuing to help customers realize the value in Vblock above and beyond the best of breed hardware components. The VCE Vblock Version Tool can be found on the VCE Partner Portal and customers can get the tool from VCE Support Portal.

SearchMyVM Needs YOUR Input Print E-mail
Written by Kendrick Coleman

I received an email today from the product manager at VKernel asking about additional features the community would like in their free product SearchMyVM. If you're not familiar with SearchMyVM it can be described as a "google-like" interface for your vCenter environment. You can run queries against your environment, and do searches. It's an appliance based VM so you don't pay any licensing cost, and the product is absolutely free. It's a great way for admins to let other people in IT see what resources are being consumed and are free within the virtual environment. SearchMyVM has also been on my Top 10 Best Free Tools list. If you haven't checked it out, I encourage you to.

 

The product management wants to know what YOU would like to see in their new version. If you have any suggestions, please leave a comment or send me an email kendrickcoleman [@] gmail [dot] com and I'll relay it back to the team.

Rethinking Your vCloud Director Provider vDC Strategy with Vblock Print E-mail
Written by Kendrick Coleman   
Friday, 09 December 2011 09:26

There are two spiking trends in the market that I see today. The first is Enterprises and Service Providers are looking to build some sort of cloud infrastructure. I know everyone has a different definition of "cloud infrastructure", but I'm referring to companies that are focused higher in the stack. Speeds and feeds are great, new hardware is great, but at the end of the day those are capital expenditures and make IT departments a cost center. The goal of a cloud infrastructure is to start your ROIC, Return on Investment Capitol, as soon as possible so the business can gain value. While you keep acquiring new equipment, it still takes weeks or months for it to even be implemented as part of your production cloud. I say that it takes this long because a true cloud solution is not only based off of virtualization, but you need to have an orchestration strategy that automates the provisioning of new resources. Picture this, Cluster A only has 10% of free RAM available, a warning is sent to the cloud admin to investigate the situation. The cloud admin finds out that workloads cannot be dispersed to another cluster so an order for 2 blade servers are placed. Once those new blade servers are shipped, the cloud admin inserts those blades into free chassis slots. From there, automation takes over. The chassis recognizes new blades, applies a pre-defined service profile, auto-deploys ESXi, and the ESXi configuration tasks take over to add the new blades to the cluster for HA and DRS resources, along with mounting datastores and configuring networks. The cluster is now at 30% free RAM.  That is called cloud automation and many companies see the light today using products such as Cisco IA, vCloud Director, and vCenter Orchestrator or even using custom code. This is the new wave of innovation that developers and admins need to be prepared for.
