VMware Cloud on AWS – Supplemental Storage – A Few Notes …

At VMware Explore 2022 in the US, VMware announced a number of new offerings for VMware Cloud on AWS, including something we’re calling “Supplemental Storage”. There are some great (official) posts that have already been published, so I won’t go through everything here. I thought it would be useful to provide some high-level details and cover some of the caveats that punters should be aware of.

 

The Problem

VMware Cloud on AWS has been around for just over 5 years now, and in that time it’s proven to be a popular platform for a variety of workloads, industry verticals, and organisations of all different sizes. However, one of the challenges that a hyper-converged architecture presents is that resource growth is generally linear (depending on the types of nodes you have available). In the case of VMware Cloud on AWS, we (now) have 3 nodes available for use: the I3, I3en, and I4i. Each of these instances provides a fixed amount of CPU, RAM, and vSAN storage for use within your VMC cluster. So when your storage grows past a certain threshold (80%), you need to add an additional node. This is a longwinded way of saying that, even if you don’t need the additional CPU and RAM, you need to add it anyway. To address this challenge, VMware now offers what’s called “Supplemental Storage” for VMware Cloud on AWS. This is ostensibly external dat stores presented to the VMC hosts over NFS. This comes in two flavours: FSx for NetApp ONTAP and VMware Cloud Flex Storage. I’ll cover this in a little more detail below.

Amazon FSx for NetApp ONTAP

The first cab off the rank is Amazon FSx for NetApp ONTAP (or FSxN to its friends). This one is ONTAP-like storage made available to your VMC environment as a native service. It’s fully customer managed, and VMware managed from a networking perspective.

[image courtesy of VMware]

There’s a 99.99% Availability SLA attached to the service. It’s based on NetApp ONTAP, and offers support for:

  • Multi-Tenancy
  • SnapMirror
  • FlexClone
​Note that it currently requires VMware Managed Transit Gateway (vTGW) for Multi-AZ deployment (the only deployment architecture currently supported), and can connect to multiple clusters and SDDCs for scale. You’ll need to be on SDDC version 1.20 (or greater) to leverage this service in your SDDC, and there is currently no support for attachment to stretched clusters. While you can only connect datastores to VMC hosts using NFSv3, there is support for connecting directly to guest via other protocols. More information can be found in the FAQ here. There’s also a simulator you can access here that runs you through the onboarding process.

 

VMware Cloud Flex Storage

The other option for supplemental storage is VMware Cloud Flex Storage (sometimes referred to as VMC-FS). This is a datastore presented to your hosts over NFSv3.

Overview

VMware Cloud Flex Storage is:

  • A natively integrated cloud storage service for VMware Cloud on AWS that is fully managed by VMware;
  • Cost effective multi-cloud Cloud storage solution built on SCFS;
  • Delivered via a two-tier architecture for elasticity and performance (AWS S3 and local NVMe cache); and
  • Provides integrated Data-Management.

In short, VMware has taken a lot of the technology used in VMware Cloud Disaster Recovery (the result of the Datrium acquisition in 2020) and used it to deliver up to 400 TiB of storage per SDDC.

[image courtesy of VMware]
The intent of the solution, at this stage at least, is that it is only offered as a datastore for hosts via NFSv3, rather than other protocols directly to guests. There are some limitations around the supported topologies too, with stretched clusters not currently supported. From a disaster recovery perspective, it’s important to note that VMware Cloud Flex Storage is currently only offered on a single-AZ basis (although the supporting components are spread across multiple Availability Zones), and there is currently no support for VMware Cloud Disaster Recovery co-existence with this solution.

 

Thoughts
I’ve only been at VMware for a short period of time, but I’ve had numerous conversations with existing and potential VMware Cloud on AWS customers looking to solve their storage problems without necessarily putting everything on vSAN. There are plenty of reasons why you wouldn’t want to use vSAN for high capacity storage workloads, and I believe these two initial solutions go some ways to solving that issue. Many of the caveats that are wrapped around these two products at General Availability will be removed over time, and the traditional objections relating to VMware Cloud on AWS being not great at high-capacity, cost-effective storage will also have been removed.
Finally, if you’re an existing NetApp ONTAP customer, and were thinking about what you were going to do with that Petabyte of unstructured data you had lying about when you moved to VMware Cloud on AWS, or wanting to take advantage of the sweat equity you’ve poured into managing your ONTAP environment over the years, I think we’ve got you covered as well.

Brisbane VMUG – August 2022

The August 2022 edition of the Brisbane VMUG meeting will be held on Wednesday 31st August at the QUT, Science and Engineering – P block from 5pm – 7pm. It’s sponsored by Dell Technologies and promises to be a great afternoon.

Here’s the agenda:

Transitioning from a Cloud-first to a Data-first Strategy to Drive Business Value

With the major trends in industry – the unpresented growth in data; increased distribution of data with the rise of Edge computing; greater diversity of data types based on industry specific use cases; increased security threats – the need for Data Management in a multi-cloud & distributed world are more important than ever. In the last few years we’ve seen the pace of digitization increase as business needs to be conducted in a virtual and digital way. Being able to manage and extract value from data is more critical than ever. In this session we will discuss how a move to a data-first strategy can drive business value, and look at an example of how an F1 racing team has put this into practice.

Presented by Ryan Tassotti – Principal Systems Engineer, Dell Technologies

This will be followed by a pizza and networking break.

Accelerate Cloud Transformation with VMware: Fuel Growth and Innovation

Help your organisation modernise existing data centre infrastructure, operating model and apps. Aging infrastructure in data centres doesn’t scale, is inefficient, lacks resiliency/agility and is not secure. Organisations do not have time, enough talent or capital to maintain the rigid data centre. Optimise capital by running and managing in a cloud model.

During this presentation, we will discuss the following use cases:

  • Take the fastest path and lowest costs to cloud-based infrastructure
  • Optimise service delivery, costs, and performance with consistent operations
  • Adopt a comprehensive platform to run modern applications

Presented by Sean Kopelke – Senior Director, Solution Engineering, VMware

And we will be finishing off with the Community Session (speaker and topic TBA)

Dell Technologies has gone to great lengths to make sure this will be a fun and informative session. You can find out more information and register for the event here. I hope to see you there. Also, if you’re interested in sponsoring one of these events, please get in touch with me and I can help make it happen.

VMware Cloud on AWS – TMCHAM – Part 7 – Elastic DRS and Host Failure Remediation

In this edition of Things My Customers Have Asked Me (TMCHAM), I’m going to delve into some questions around managing host additions and failures on the VMware-managed VMware Cloud on AWS platform.

Elastic DRS

One of the questions I frequently get asked by customers is what happens when you reach a certain capacity in your VMware Cloud on AWS cluster? The good news is we have a feature called Elastic DRS that can take care of that for you. Elastic DRS is a little different to what you might know as the vSphere Distributed Resource Scheduler (DRS). Elastic DRS operates at a host level and takes care of capacity constraints in your VMC environment. The idea is that, when your cluster reaches a certain resource threshold (be it storage, vCPU, or RAM), Elastic DRS takes care of adding in additional host resources as required. 

The algorithm runs every 5 minutes and uses the following parameters:

  • Minimum and maximum number of hosts the algorithm should scale up or down to.
  • Thresholds for CPU, memory and storage utilisation such that host allocation is optimized for cost or performance.

Note also that your cluster may scale back in, assuming the resources stay consistently below the threshold for a number of iterations.

Settings

There are a few different options for Elastic DRS, with the default being the “Elastic DRS Baseline Policy”. With this policy, a host is automatically added when there’s less than 20% free vSAN storage. Note that this doesn’t apply to single-node SDDC configurations, and only the baseline policy is available with 2-node configurations. Beyond those limitations, though, there are a number of other configurations available and these are outlined here. The neat thing is that there’s some amount of flexibility in how you have your SDDC automatically managed, with options for best performance, lowest cost, or rapid scale-out also available.

Can I Turn It Off?

No, but you can fiddle with the settings from your VMC cloud console.

Other Questions

What happens if I’m adding a host manually? The Elastic DRS recommendations are ignored. Same goes with planned maintenance or SDDC maintenance, where the support team may be adding in an additional host. But what if you’ve lost a host? The auto-remediation process kicks in and the Elastic DRS recommendations are ignored while the failed host is being replaced. You can read more about that process here.

 

Thoughts

One of the things I like about the VMware Cloud on AWS approach is that VMware has looked into a number of common scenarios that occur in the wild (hosts running out of capacity, for example) and built some automation on top of an already streamlined SDDC stack. Elastic DRS and the Auto-Scaler features seem like minor things, but when you’re managing an SDDC of any significant scale, it’s nice to have the little things taken care of.

Brisbane VMUG – July 2022

The July edition of the Brisbane VMUG meeting will be held on Wednesday 20th July at the Atrium (Level 6), QUT Science & Engineering Centre (P Block) from 5pm – 7:30pm. It’s sponsored by VMware and promises to be a great evening. Agenda as follows.

 

What is Azure VMware Solution and Why Would You Choose it?

Azure VMware Solution allows you to run VMware workloads on a private cloud in Azure. Not only is it the fastest way to migrate to workload, but it is also the most sensible in many cases.

In the session we will help you understand what AVS is, how it delivers a VMware environment that allows customers to take advantage of Azure, and also how it’s different to other VMware hyperscaler offerings. We’ll cover the platform and deployment, how can be AVS is networked to on-prem and the Internet, and how AVS is managed through a familiar VMware toolset.

We’ll show how VMware HCX can dramatically simplify migration or workloads from an existing on-prem VMware environment to AVS, minimising technical risk and significantly lowering migration costs. And we’ll also explain the benefits of Azure Hybrid use Benefit and Extended Security Update savings that are unique to AVS.

Finally, we’ll present a typical TCO as an illustration of the typical savings in moving to AVS versus on-prem or public cloud alternatives.

Delivered by:

  • Anthony Higgins – Cloud Solution Architect (VMware)
  • Greg Cetinich – Senior Sales Manager (VMware)
  • David Wymer – Global Black Belt (Microsoft)

 

Pizza and Networking Break

This will be followed by:

 

Ensure Clear Skies with Inbuilt Cloud Security

Cloud projects in 2022 are less about adoption, but more about optimisation, migration and security as “cloud-first” has become “cloud-default”. In this session we will discuss how systems, applications and hosts are migrating, optimising, transforming and securing their cloud workloads with little to no added effort. How VMware customers and net-new environments can leverage next-gen platforms to gain added functionality and extend their visibility, control and protection platforms to all locations.

Agenda:

  • Cybersecurity 2022 Recap
  • Cloud Adoption and Optimisation Priorities
  • Workload Security – Integrated awareness & protection for cloud workloads
  • Container Security – Pre & Post Deployment security
  • Demo
  • Q&A

Delivered by:

  • Sean Scott – Endpoint & Workload Security Practice Lead (VMware, QLD)
  • Vikram Kumar – Senior Solutions Engineer (VMware)

 

Other Notes

Soft drinks and vBeers will be available throughout the evening! We look forward to seeing you there! Doors open at 5pm. Please make your way to The Atrium, on Level 6.

Random Short Take #74

Welcome to Random Short Take #74. Let’s get random.

VMware Cloud on AWS – TMCHAM – Part 6 – Sizing

In this edition of Things My Customers Have Asked Me (TMCHAM), I’m going to touch briefly on some things you might come across when sizing workloads for the VMware Cloud on AWS platform using the VMware Cloud on AWS Sizer.

VMware Cloud on AWS Sizer

One of the neat things about VMware Cloud on AWS is that you can jump on the publicly available sizing tool and input some numbers (or import RVTools or LiveOptics files) and it will spit out the number of nodes that you’ll (likely) need to support your workloads. Of course, if that’s all there was to it, you wouldn’t need folks like me to help you with sizing. That said, VMware has worked hard to ensure that the sizing part of your VMware Cloud on AWS planning is fairly straightforward. There are a few things to look out for though.

Why Do I See A Weird Number Of Cores In The Sizer?

If you put a workload into the sizer, you might see some odd core counts in the output. For example, the below screenshot shows 4x i3en nodes with 240 cores, but clearly it should be 192 cores (4x 48).

Yet when the same workload is changed to the i3 instance type, the correct amount of cores (5x 36 = 180) is displayed.

The reason for this is that the i3en instance types support Hyper-Threading, and the Sizer applies a weighting to calculations. This can be changed via the Global Settings in the Advanced section of the Sizer. If you’re not into HT, set it to 0%. If you’re a believer, set it to 100%. By default it’s set to 25%, hence the 240 cores number in the previous example (48 x 1.25 x 4 nodes).

Why Do I Need This Many Nodes?

You might need to satisfy Host Admission Control requirements. The current logic of Host Admission Control (as it’s applied in VMC sizer) is as follows:

  • A 2-host cluster should have 50.00 percent reserved CPU and memory capacity for HA Admission Control.
  • A 3-host cluster reserves 33.33 percent for HAC

And so on until you get to

  • A 16-host cluster reserving 6.25 percent of resources for HAC.

It’s also important to note that a 2-host cluster can accommodate a maximum of 35 VMs. Anything above that will need an extra host. And if you’re planning to run a full HCX configuration on two nodes, you should review this Knowledge Base article. Speaking of running things at capacity, I’ll go into Elastic DRS in another post, but by default we add another host to your cluster when you hit 80% storage capacity.

What About My Storage Consumption?

By default there are some storage policies applied to your vSAN configurations too. A standard Cluster with 5 hosts or less is set to 1 Failure / RAID-1, whilst a standard Cluster with 6 hosts or more is set to tolerate 2 Failures / RAID-6 by default. You can read more about that here.

Conclusion

There’s a bunch of stuff I haven’t covered here, including the choices you have to make between using RVTools and LiveOptics, and whether you should size with a high CPU to core ratio or keep it one to one like the old timers like. But hopefully this post has been of some use explaining some of the quirky things that pop up in the Sizer from time to time.

VMware Cloud on AWS – TMCHAM – Part 5 – VM Management

In this edition of Things My Customers Have Asked Me (TMCHAM), I’m going to delve into some questions around managing VMs running on the VMware-managed VMware Cloud on AWS platform, and talk about vCenter plugins and what that looks like when you move across to VMware Cloud on AWS.

How Can I Access vCenter?

VMware vCenter has been around since Hector was a pup, and the good news is that it can be used to manage your VMware Cloud on AWS environment. It’s accessible via a few different methods, including PowerCLI. If you want to access the HTML5 UI via the cloud console, you’ll need to ensure there’s a firewall rule in place to allow access via your Management gateway – the official documentation is here. If the rule has already been created and you just need to add your IP to the mix, here’s the process.

The first step is to find out your public IP address. I use WhatIsMyIP.com to do this.

In your console, go to Networking & Security -> Inventory -> Groups.

Under Groups, make sure you select Management Groups.

You’ll find a Group that was created that stores the IP information of folks wanting to access vCenter. In this example, we’ve called it “SET Home IP Addresses”.

Click on the vertical ellipsis and click Edit.

Click on the IPs section.

You’ll then see a spot where you can enter your IP address. You can do a single address or enter a range, as shown below.

Click Apply and then click Save to save the rule. Now you should be able to open vCenter.

Can I run RVTools and other scripts on my VMC environment?

Yes, you can run RVTools against your environment. In terms of privilege levels with VMware Cloud on AWS, you get CloudAdmin. The level of access is outlined here. It’s important to understand these privilege levels, because some things will and won’t work as a result of these.

Can I lockdown my VMs using PowerShell?

You will have the ability to set these advanced settings on your VMs in the SDDC, but this is limited to per-VM, rather than on a per-cluster basis. So if you normally ran a script on a pre-VM basis to harden the VM config, you’d need to run that on each VM individually, rather than on a per-cluster level.

What about vCenter plugins?

We don’t have a concept of vCenter plugins in VMware Cloud on AWS, so there are different ways to get the information you’d normally need. vROps, for example, has the ability to look at VMware Cloud on AWS, using either the on-premises version or the cloud version. There’s information on that here, but note that the plugin isn’t supported with VMC vCenter.

What about my Site Recovery Manager plugin? The mechanism for managing this will change depending on whether you’re using SRaaS or VCDR to protect your workloads. There’s some good info on SRaaS here, and some decent VCDR information here. Again, there is no plugin available, but the element managers are available via the cloud console.  

What about NSX-V? VMware Cloud on AWS is all NSX-T, and you can access the NSX Manager via the cloud console.

Conclusion

A big part of the reason people like VMware Cloud on AWS is that the management experience doesn’t differ significantly from what you get VMware Cloud Foundation of VMware Validated Designs on-premises. That said, there are a few things that do change when you move to VMware Cloud on AWS. Things like plugins don’t exist, but you can still run many of the scripts you know and love against the platform. Remember, though, it is a fully managed service, so some of the stuff you used to run against your on-premises environment is no longer necessary.

VMware Cloud on AWS – TMCHAM – Part 4 – VM Resource Management

In this episode of Things My Customers Have Asked Me (TMCHAM), I’m going to delve into some questions around resource management for VMs running on the VMware-managed VMware Cloud on AWS platform, and what customers need to know to make it work for them.

Distributed Resource Scheduler

If you’ve used VMware vSphere before, it’s likely that you’ve come across the Distributed Resource Scheduler (DRS) capability. DRS is a way to keep workloads evenly distributed across nodes in a cluster, and moves VMs around based on various performance considerations. The cool thing about this is that you don’t need to manually move workloads around when a particular guest or host goes a little nuts from a CPU or Memory usage perspective. There are cases, however, when you might not want your VMs to be moving around too much. In this instance, you’ll want to create what is called a “Disable DRS vMotion Policy”. You configure this via Compute Policies in vCenter, and you can read more about the process here.

If you don’t like reading documentation though, I’ve got some pictures you can look at instead. Log in to your vSphere Client and click on Policies and Profiles.

Then click on Compute Policies and click Add.

Under Policy type, there’s a dropdown box where you can select Disable DRS vMotion.

You’ll then give the policy a Name and Description. You then need to select the tag category you want to use.

Once you’ve selected the tag category you want to use, you can select the tags you want to apply to the policy.

Click on Create to create the Compute Policy, and you’re good to go.

Memory Overcommit Techniques

I’ve had a few customers ask me about how some of the traditional VMware resource management technologies translate to VMware Cloud on AWS. The good news is there’s quite a lot in common with what you’re used to with on-premises workload management, including memory overcommit techniques. As with anything, the effectiveness or otherwise of these technologies really depends on a number of different factors. If you’re interested in finding out more, I recommend checking out this article.

General Resource Management

Can I use the resource management mechanisms I know and love, such as Reservations, Shares, and Limits? You surely can, and you can read more about that capability here.

Conclusion

Just as you would with on-premises vSphere workloads, you do need to put some thought into your workload resource planning prior to moving your VMs onto the magic sky computers. The good news, however, is that there are quite a few smart technologies built into VMware Cloud on AWS that means you’ve got a lot of flexibility when it comes to managing your workloads.
