VLC-Build it for me, vRealize Operations deployment – VCF 3.9.1

If you’ve been following the VLC-Build it for me posts you should have VRSLCM up and running. As promised this exercise will be quite a bit shorter due to the work we put in getting VRSLCM built. vRealize Operations gives a view into operations management of both applications and infrastructure and, in the context of VCF, as you grow your solution help you plan, scale, and easily connect new Workload domains and their resources to be included in vROps pervue.

VLC-Build it for me, VRSLCM deployment– VCF 3.9.1

After getting your external access up and running, I’m sure your ready to start deploying some additional solutions! Let’s start with the vRealize suite and that all begins with downloading and deploying VRSLCM – (vRealize Suite Lifecycle Manager). Go ahead and get that queued up and downloading, it’s about 3GB in size and it should be available under the Repository -> Bundles page, click the Download Now button next to the vRealize Suite Lifecycle Manager bundle.

Make a Local VCF Depot

VMware Cloud Foundation (VCF) communicates periodically through the internet with a hosted web service in order to check for and retrieve software updates and bundles. What if you don’t have internet access? Today, I’m going to demonstrate how you can build out your own software repository for VCF.

Before we begin, it’s important to note that this process is not supported for production environments. To understand why, I need to give you a short overview of what I will be showing you today.

VLC – Build it for me, External Access

So you got through all the BGP fun and have a fully deployed VCF instance, congrats! Of course now, you want do add some functionality and get your FULL SDDC on. Thankfully, there are only a few more steps to go and you’re already an expert at this.

The long and short of it is that SDDC manager will need access to https://depot.vmware.com. That means you’ll need outbound network connectivity and DNS resolution. Let’s talk about the outbound network connectivity first.

VCF Bringup with Multiple Physical NICs

I’ve talked about how to use hosts that have multiple physical NICs to create NSX-V and NSX-T backed workload domains and even how to expand a cluster in one of these workload domains. But what if you want to do an initial installation of VMware Cloud Foundation (VCF) using hosts with multiple physical NICs?

As I’ve mentioned before, the support for multiple physical NICs with VCF is new with VCF 3.9.1. All of the operations we performed previously relied on the VCF API. This worked well for our intended use, but bringup is a different animal.

NSX-T Backed Workload Domains with Multiple Physical NICs

Last week, I shared an example of how to create a new workload domain with VMware Cloud Foundation (VCF) using hosts with more than two physical NICs. In that example, I used NSX-V in the creation of the workload domain. Today, I’d like to provide an example of how you would do this for a NSX-T backed workload domain.

As support for multiple physical NICs (>2) is a newly supported feature with the VCF 3.9.1 release, doing this requires the use of the VCF APIs.

Multiple Physical NICs in VCF

With the VCF 3.9.1 release, support for hosts with multiple physical NICs has been added. This allows you to dedicate specific traffic across specific physical NICs to conform to your best practices. Let’s take a quick look at how this is configured…

By default, VCF will use the first two physical NICs (vmnic0 and vmnic1) on a host for all traffic. When working with a host with multiple physical NICs, you will need to define what the physical NICs are connected to (VDS or N-VDS). The VDS or N-VDS will need to exist, of course.

Manually Uploading VCF Bundles

Although VMware Cloud Foundation (VCF) will automatically download the software bundles once connected to the Internet, there are times that you may wish to manually inject the software bundles into the SDDC Manager using the API.

After the initial deployment of VCF is completed, additional bundles may be required to enable optional functionality. For example, the bundles for Horizon, PKS, and vRealize Automation are optional and would be downloaded and then installed as needed. Because these bundles can be quite large and VCF downloads them in a serial fashion, it can be faster at times to inject the bundles into VCF manually through the API.

Resizing the LCM Volume group on SDDC Manager

One of the users of the VLC (VCF Lab Constructor) had an issue with drive space when attempting to upgrade from VCF 3.9 -> 3.9.1. This has been a problem in previous releases at times as well, so I thought it’d be a good opportunity to post about it. That and I don’t post nearly as often as I want to!

SDDC Manager uses LVM for several of it’s critical mount points. Coupled with the EXT4 filesystem this allows those mounts to be very flexible and non-disruptive when increasing their size.
