Quick Tip: Change the Password on the vCNS Edge

By Martijn Baecke, VMware Senior Consultant

Martijn BaeckeDeploying and managing a vCNS Edge device with vCloud Director is a pretty easy task. You just spin up the appliance, integrate it with vCenter and then hook it up to vCloud Director. Piece of vCAC!

I was trying to dig deeper into the structure of how vCNS Edge devices work and wanted to log in to the Edge device itself. The only problem was fact that I couldn’t log into console of the Edge appliance that was deployed by vCNS manager on my virtual infrastructure. Thankfully, the vCNS Manager interface provides you with the possibility to reset the password.

To reset the password and be able to log into the vCNS Edge device:

1. Log into the vCNS web interface.
2. At “View:” in the left corner, select Edges.
3. Select the Edge Gateway you want to log into.
4. Click Actions and select Change CLI Credentials.

This allows you to set the password for the “admin” account. With these credentials you can login to the vCNS Edge device.

Think Like a Service Provider, Build in vCenter Resilience

Jeremy Carter headshot By Jeremy Carter, VMware Senior Consultant

When I’m working on a customer engagement, we always strategize to ensure resiliency and failover protection for vCenter Automation Center (vCAC). While these considerations continue to be top priorities, there is another question that seems to be coming up more and more: “What about vCenter?”

vCenter has long been thought of as the constant, the unshakable foundation that supports business differentiators like vCAC. Although we’re happy for that reputation, it’s important for IT organizations to take the appropriate actions to protect all components up and down the stack

This is increasingly necessary as organizations move into an IT-as-a-Service model. As more parts of the business come to rely on the services that IT provides, IT must be sure to deliver on its SLAs—and that means improved resilience for vCenter as well as the applications that sit on top of it.

Our customers have found vCenter Server Heartbeat to be an essential tool to support this effort. Heartbeat allows IT to monitor and protect vCenter from a centralized easy-to-use web interface and protects against application or operator errors, operating system or hardware failure and external. In addition to protecting against the unplanned downtime, it provides improved control during planned downtime, such as during Windows updates, allowing patches without vCenter downtime.

In the past, Heartbeat was most popular with service providers who needed to securely open up vCenter to customers. Now that more IT organizations are becoming service providers themselves, I encourage them to support their internal customers at the same level and make sure vCenter resilience and protection is part of the plan.

VMworld Schedule Builder Now Live!

We’re excited to announce the schedule builder for VMworld San Francisco 2013 is now live. Considering this year’s 350 in-depth sessions, 26 hands-on labs, 275 sponsors and exhibitors, and networking opportunities galore, you’ll be glad for the help making the most efficient use of your VMworld time. And if you haven’t registered, now is the time!

As you’re building your ideal schedule, consider adding some sessions from our Professional Services Consultants. We’ve been highlighting their sessions the last few weeks, and are finishing up this week with one from Joerg Lew on vCenter Orchestrator.


Keep It Simple and Integrated: Out-Of-The-Box Cross-System Automation with vCenter Orchestrator (vCO)

With Joerg Lew (VMware) and Savina Ilieva (VMware)

 For service providers and enterprises alike, automation and integration is the key to efficiently building and operating your IT infrastructure, whether it’s virtualized or still contains legacy devices and applications. With vCenter Orchestrator (already included in vCenter), you can build reliable “enterprise-ready” automation solutions based on workflows. vCO and its plugins allow you to integrate a broad number of systems, protocols, and services, including but not limited to VMware products.

In this session you’ll learn about:

  • The business case for automation and integration in enterprise IT
  • New features planned for the next vCO release
  • Using existing plugins to auto-generate workflow for many use cases
  • Integrating external systems with vCO

You will see a live demo of the newest vCO capabilities, presented by Savina Ilieva, Product Manager for vCO at VMware, and Joerg Lew, Senior Consultant in VMware’s Professional Services Engineering team. A guest speaker from a third-party vendor will also share his experience building a vCO Plugin. Who is it? Attend the session and see!


Four Commonly Missed and Easy to Implement Best Practices

By Nathan Smith, VMware EUC Consultant

I want to highlight a few of the best practices in a View deployment that are often overlooked but easily corrected.  My highlights are based on our practice’s collective experience with one  of the services offered by EUC Professional Services, the Desktop Virtualization Health Check. These are normally undertaken after the environment has been up and running for a while or ahead of a significant expansion. Amongst other things the Health Check includes a comparison of both vSphere and View best practices to your current environment. In total we check over 150 best practices. Some are straightforward and hopefully done already – for example, using separate vSphere environments for the Desktops and Infrastructure components. Some are a little more esoteric, like reviewing the congestion threshold for SIOC.

1. Configure a vCenter user and role with appropriate permissions.  It is often tempting when going through a deployment to use an account that you know isn’t going to run in to permissions issues. This frequently ends up being a full vCenter Administrator. While this approach will work, it is not recommended to provide more permissions than are necessary. Correcting this is straightforward. Setup a new vCenter Role with the privileges defined in the View Administrators Guide (be sure to add the Composer and Local Mode privileges if you are using those features) and assign permissions at the vCenter level for a new user using this role. In View Administrator modify the account used to connect to vCenter under View Configuration->Servers-> vCenter Servers->Edit.

2. The next two considerations both fall in to the same category, virtual hardware configuration. The first is the virtual network adapter type. This should be VMXNET3 for both Windows XP and 7. The second is to verify that the disk controller is an LSI Logic controller. This should be LSI Logic Parallel or SAS for Windows XP and LSI Logic SAS for Windows 7. Simon Long does a great job of summarizing the reasoning here.

3. Appropriately size the Connection Server and JVM heap. The recommendation for RAM on Connection Servers supporting over 50 desktops is 10GB on a Windows Server 2008 R2 and 6GB on a Windows 2003 Server. If you are increasing memory on a 2008 R2 installation you will need to reinstall Connection Server to reset the JVM heap size. On a 2003 server you can follow this section from the Administrators guide. Also consider whether you have increased memory in the past, for example, when moving from pilot to production. Note that as of View 5.1, Windows 2003 is no longer a supported operating system for Connection Servers.

4. The last area I want to highlight is OS Optimization. There are two technical papers available, one for Windows XP and one for Windows 7, that take you step by step through the best practices for optimizing the OS. These perhaps don’t fall in to the easy to implement category as they are a little more time consuming but really essential to a successful deployment.

Good luck with your deployment and don’t hesitate to contact your EUC Professional Services lead with questions.
