Question

Azure Site Recovery - Choose or change premium page blobs size

Dennis Birk 406

Hello,

I see in the Azure bill that Azure Site Recovery use e.g. Premium Page blob P30 disks.
I see of course also the same disk type in the ASR deployment planner.
On which basis choose ASR Vault this disk size? Can I change the disk type e.g. from P30 to P20 or is this possible to choose from scratch a disk type?

I found no option for this.

Hi @Dennis Birk

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

Azure Site Recovery automatically selects the disk size based on the workload requirements gathered during the ASR deployment planner calculations.
For example, if the workload requires high performance and capacity, it will select Premium disks. You can change the disk type by configuring replication settings in the Azure Portal before configuring replication.

So, you can choose any disk type that is supported by Azure Site Recovery, and which meets the requirements of your workload.
This information is specified in the Point#9 at the following document https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-enable-replication

For Properties > Configure properties, select the account that the process server uses to automatically install the Site Recovery Mobility service on the VM. Also, choose the type of target managed disk to use for replication based on your data churn patterns.

You can refer to the support matrix in the documentation to understand the limitations and requirements for different disk types. https://learn.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix#churn-limits

Hope this helps!

Thanks for this information. Your link is related to a VMware environment. I use a Hyper-V environment. Is this also possible to change the disk type? I found no infos in the docs regarding Hyper-V.

Looking at the Hyper-V document, I don't see that option during enable replication phase. I will have to test this. Let me check and update you. https://learn.microsoft.com/en-us/azure/site-recovery/hyper-v-azure-tutorial#enable-replication

Hi DeBi

I haven't had the technical feasibility to set up this scenario in my lab unfortunately. I had researched and found this in the following doc https://learn.microsoft.com/en-us/azure/site-recovery/hyper-v-deployment-planner-overview where it confirms that.

You choose the storage type per VM, based on workload characteristics, for example, read/write I/O operations per second (IOPS), or data churn, and Azure Site Recovery limits.

For any further clarification, I suggest checking this in a test scenario before you enable the replication.

If the information provided on this thread answered your queries, would you be so kind to Accept Answer and Upvote the same please.
