The Hyper-V Amigos ride again! In this episode (19) we discuss some testing we are doing to create high performant backup targets with Storage Spaces in Windows Server 2019. We’re experimenting with stand-alone Mirror Accelerated Parity with SSDs in the performance tier and HDDs in the capacity tier on a backup target. We compare backs via the Veeam data mover to this repository directly as well as via an SMB 3 file share. We look at throughput, latency and CPU consumption.
One of the questions we have is whether an offload card like SolarFlare would benefit backups as these offload not just RDMA capable workloads. The aim is to find how much we can throw at a single 2U backup repository that must combine both speed and capacity. We discuss the reasons why we are doing so. For me, it is because rack units come at a premium price in various locations. This means that spending money to come up with repository building blocks that offer performance and capacity in fewer rack units ensure we spend the money where it benefits us. If the number of rack units (likely) and power (less likely) are less of a concern the economics are different.
We also address the drawbacks of an SMB 3 backup target and we will show you a solution in a later episode when we leverage a continuously available file share to solve this while also providing failover capabilities. This can be done via S2D or shared storage. The question remains if storage spaces put too much load on the CPUs compared to a RAID controller approach, but this is debatable today. When it comes to write-back cache, that’s why they invented MVMe!
One benefits with storage spaces is that ReFS can auto repair corrupt bist from the redundant copies and as such offers protection against bit rot.
While this is just a small lab setup we are getting some interesting results and pointers to further investigate. The only real show stopper is the ridiculous up mark OEMs have for SSD and NMVE drives. That is way too high and more than any added value of testing and support can justify.
Anyway, enjoy the webcast and we hope to deliver a few follow-ups in the near future. Even PMEM with Intel Optane DC memory is in the works!
Your humble Hyper-V Amigos
Join the Hyper-V amigos who test Persistent Memory (PMEM in the lab a bit).PMEM is solid-state high-performance byte-addressable memory device that resides on the memory bus. If you have not heard of or read up on PMEM it is really time you do.
Let’s find out what it is and where it fits in. PMEM is dominating the buzz on the storage and memory scene at the moment, it is “hot”. Rightly so, PMEM is changing how the IT world thinks about and consumes storage. Not wholesale overnight but it will be a game changer.
The nature of PMEM improves the way applications use CPU cycles, how data is retrieved and persisted as well as how memory is consumed. This means significant changes in the hardware and software stack are needed to leverage these capabilities. An era of very fast, high capacity, low latency storage class memory with high endurance is coming.
We hope you enjoy the Episode.
Didier & Carsten
While we, the Hyper-V amigos (Carsten Rachfahl and Didier Van Hoye) are updating on of their labs from Veeam backup & Recovery 9.5 Update 3 to Update 4 we talk about what’s new in this release. We don’t succeed in covering it all, let alone to do so in detail. There is just too much in this release.
The upgrade itself goes smooth as silk, which is what we have become to expect from Veeam. Not that we were confused a moment when ze couldn’t disable the jobs prior to the upgrade, well they were not scheduled in the lab.
We have future plans to do some demos of new capabilities like support for object based storage, Veeam Agent for Windows 3.0 etc.
We have started testing this feature already with a Minio Docker container on a Synology. Pay attention to the Unofficial object storage compatibility list for Capacity Tier as we also noticed that the Windows service seems to have scalability issues.
We’ll be taking a look at this in the future.
What was possible in Azure is now extended to more use cases. This make perfect sense as the market is diverse and you have to serve all the customers. Imagine moving very easily VMs between on-premises and different cloud solutions as the conversion details are handled for you.
Any tool that can help be more compliant and secure is a good one. Helping you be GDPR compliant for example or helping you protect restores form introducing ransom ware are prime examples of this. This is another feature we’ll look at.
When you use the Oracle or SAP HANA you will appreciate the fact that these can be protected by Veeam. Is this a big want? Yes. Sure, not by me personally, but it is a big deal to many customers. Let me tell you that I once met an IT director that would be trilled if Veeam would protect AS400. Needs differ.
Self service is important to organizations that offer data protection, availability and mobility to external or internal customers. It helps optimize the process for all parties involved.
Well this is a Veeam One feature actually. Any sizable support organization has tooling to collect and parse logs in order to get to the (root) causes of issues as soon as possible. They have to in order to scale support. If not, they’d drown in work and need too many people to make if feasible and have anything close to excellent support that solves issues within a reasonable amount of time. I don’t know many that are sharing the capabilities of their tooling with their customers. This makes me think Veeam must be pretty confident in the quality of the tooling to do so. I’m curious to hear the feedback on how much it helped customers and as such Veeam support.
Microsoft Windows Server 2019 support as guest OS of virtual machines protected by Veeam Backup & Replication, for installation
of Veeam Backup & Replication and all of its remote components, and for backup with Veeam Agent for Microsoft Windows.
Microsoft Windows 10 October 2018 Update support as guest OS of virtual machines protected by Veeam Backup & Replication,
support as guest virtual machines, for installation of Veeam Backup & Replication and all of its remote components, and for backup with Veeam Agent for Microsoft Windows.
Microsoft Windows Server Hyper-V 2019 support as a hypervisor host, including support for virtual hardware version 9.0v virtual machines.
Microsoft Active Directory 2019, Exchange 2019 and SharePoint 2019 support for application-aware processing, and for item level recoveries with Veeam Explorer.
Oracle Database 18c support for application-aware processing on Windows-based virtual machines, including transaction log backup and point-in-time restores.
VMware vSphere 6.7 U1 ESXi, vCenter Server and vCenter Server Appliance (VCSA) support.
VMware vCloud Director 9.5 support.
Veeam keeps building a strong ecosystem of partners to give customers the ability to protect their data in more ways than they could easily or cost effectively deal with by themselves.
Don’t panic, don’t worry, be happy. Veeam has you covered and even has this nice Instance based “we got your back” grace counting. When you need 22 instances you don’t have to buy 25 (sold in bundles of 10 or 5). You can buy 20 and the 2 extra are covered by the 5% or 5 instance (whichever comes first) margin Veeam gives you. The main thing to realize is that the instance licensing make licenses very portable to where you protect and restore data. Read up on it at Veeam Licensing Policy and in Frequently Asked Questions
We have enhancements and additions to the product for both backup and restore functionality, 3rd party integration, the Veeam Agents, the explorers etc. You can read it all for yourself right here: What’s New in 9.5 Update 4?
While you’re doing some routine maintenance or getting some labs setup, you’re very welcome to kick of the show cast. You’ll be joined by two tired (recovering from colds) IT Pro’s while they do a fast and successful update of a Veeam lab environment so we can demo so new capabilities in the future.

In this Episode Didier and Carsten talk about the Backup Improvements in Hyper-V over the past releases. Didier use some very impressive visuals to explain the hole backup process including VSS Snapshots, SAN Snapshots, Change Block Tracking and so on. But this wouldn't be a Showcast if there weren’t a lot of Demos.
In this Episode of the Hyper-V Amigos Showcast we look at VMFleet. VMFleet is a free Microsoft test suite to show the performance of a Hyper-converged Storage Spaces Direct Setup. In this Episode Didier and Carsten show you how it works, how you measure with it and how you do the complemte setup. And all of this in just around 2 hours 😉
In this Episode Carsten talkes with Charbel Nemnom Microsoft Cloud & Datacenter Management MVP like himself. Charbel is Co-Author of the Book Windows Server 2016 Hyper-V Cookbook and Carsten ask Charbel alot of questions about the book. We hope you enjoy the video.
In this Episode Didier and Carsten talk about Enhancements in Remote Graphics: RemoteFX and Discrete Device Assignment. DDA allows the Administrator to assign a PCI device like an GPU exclusively to an VM. So watch this Showcast and lear all about it.
In this Podcast Carsten talkes with Alessandro Pilotti also an Hyper-V MVP. Alessandro is a real OpenSource fan and so it haped that he started integrating Hyper-V and Windows Technologies into OpenStack. Listen to Alessandro and Carsten about the great stuff he and his Company Cloudbase Solutions is doing here.
