Resource planning for Azure Stack HCI

Hi all,

 

I'm currently in resource planning for a small cluster to evaluate it for our projects. 

 

Should I always plan double resources for the failover cluster solution for the workloads that are running on the VMs?

 

If it's so, isn't it a kind of over-provisioning? 

 

Thank you for your help in advance.

      Thank you for sharing the link 🙂

      Is there a possibility to see the price of the suggested solution?

        Parisa_Moosavinezhad as always IT depends (tm)
        OEM vendors have different prices and they can be volatile. Then it depends on your workloads and way of high availability needed, which mirroring for which CSV (and allocated VMs) and dedup settings per CSV.

         

        I have sized quite some Azure Stack HCI projects from 1 node system for Test / Dev environment to larger cluster (yet excluding stretched clusters, waiting for technical improvements on the Replica - they are included in vNext Windows Server so I have hopes they might come for Azure Stack HCI OS 23H2).

         

        One of the best way to go is a liveoptics measurement in your existing environment or using Azure Migrate for Assessment (now in preview it can also assess and migrate to Azure Stack HCI, but the main point is the projection on HW you would need.

         

        Many also oversize RAM and majorly CPU as vCore to pCore has advanced a lot with current and previous gen CPUs from Intel and AMD. In many situation I see a 8:1 or 10:1 scale of individual servers or blades that can be consolidated moving from very old to newer CPUs.

         

        So tldr: contact your preferred vendor and likely a good consultant for Azure Stack HCI to get the best price / ROI and TCO on your licensing and hardware invest.
