Let’s talk about configuring and deploying VMware Cloud Disaster Recovery #VCDR #vExpert

November 22, 2021 Bilal Ahmed 0

So, let’s talk about VCDR VMware Cloud Disaster Recovery. It was acquired from Datrium and I have some customers who are in the process of looking into it and deploying it. If you have ever used SRM, you will feel very at home with VCDR, as you will see as I explain it in more detail. I am a big fan of DR in general, I used to work for a BC/DR provider, and I lost count of the number of times people never tested their plans and were then surprised they didn’t work as they had hoped. I always used to say, you should be happy they failed now, imagine if this had been real and you couldn’t recover! […]

Automating HCX Cutover using PowerCLI #HCX #PowerCLI #vExpert

So I was provided with a script from my buddy Charlie at Tower Associates, and then myself and Dean Lewis edited it a bit to make it work alongside the scripts we had already produced in our previous posts. I’ve always been an advocate of doing the cutover manually. Cutting over 200 VMs or so in one go is daunting and lacks the control I would personally like. I like to be able to tell customers, ok we have cut over these 20 VMs for this app, please get them to test it, then when they are happy move to the next set. It is nice and controlled and instils confidence in the migration process. That is not to say […]

HCX DR Use Cases #HCX #DR #vExpert

November 8, 2021 Bilal Ahmed 0

*These are my own ramblings and nothing I say is officially supported by VMware!* So HCX does have a DR feature. It does not get talked about much, because at VMware if you are talking fully-fledged DR you will be looking into SRM and the new offering VCDR. The HCX DR service uses vSphere Replication (VR) under the hood in the same way, SRM can use vSphere Replication. The main difference is that the IX appliance in the service mesh is the vSphere Replication Manager. SRM does full-on DR orchestration, failing over VMs in a specific order, with recovery plans, HCX does not do any of that. When I have talked to GSS and some customers, I have discovered that […]

SDDC to SDDC Migrations #VMConAWS #HCX #Migrations

November 1, 2021 Bilal Ahmed 2

So I had a customer recently that had deployed a VMConAWS SDDC using a /23 subnet. This is fully supported, but they then ran into scalability issues as that subnet is limited to only allow 27 ESXi hosts. So now they wanted to scale beyond that but were stopped by this configuration limit. Now you can’t adjust that post-deployment, so this lead to a discussion about standing up a new SDDC and migrating to it or migrating into an existing SDDC that uses /20 subnet. Now there are 2 supported ways to do that using HCX and I am going to discuss both of them. I have 2 SDDCs : TF_TEST and SDDC-Jeff (great names I know!) Option 1: Deploy […]
