>> Standard HDD is an Azure storage type that should only be used to store SAP backups << as we are designing for SAP backup so choice here HDD >>>and for Geo redundancy solution- Another Region is the choice <<<

Azure Standard HDD storage-based managed disks are not supported for SAP workloads. Microsoft recommends using Azure Standard SSD storage as minimum for Azure VMs hosting the SAP application layer and for non-performance sensitive DBMS deployment and using Azure Premium SSD storage for all other Azure VMs DBMS workloads. https://docs.microsoft.com/en-us/learn/modules/using-iaas-support-azure-sap-workloads/2-storage-support-sap-workloads

correct

IMO: HDD, Multi-regions for Performance tier: https://docs.microsoft.com/en-us/azure/storage/common/storage-account-overview

two types of disks: Premium: Which means your data will be placed on solid state disks Standard: Where data is placed on regular hard disk drives source: https://www.sqlshack.com/different-azure-storage-types-file-blob-queue-table/

The Given Answer is Correct: 1. Standard SSD's 2. To another Azure region. 1: HDD's is advisable only in case of retired systems which are not used actively. Basically systems not used in a landscape of dev->test->prod. But here, question says 'you are designing SAP database', which likely means it is a part of SAP landscape and atleast a DEV or QA system will be build on the same. Hence, Standard SSD's.

Since the storage in question is for backups only and the data type is "cold", the least expensive solution is be HDD, GRS=replicated to another region. https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/planning-guide-storage#:~:text=Azure%20Ultra%20disk,-Azure%20ultra%20disks&text=Ultra%20disks%20are%20suited%20for,that%20stores%20the%20operating%20system.

Firstly this is about keeping SAP backup and it says nothing if this fulfills SAP requirement / certification or not. Secondly the storage is Standard Storage and cool tier. Cool tier has the same latency as the hot tier. Hence both are on Standard SSD. HDD is used for Archive tiers. Many of the URLs below point to what SAP needs. Hardly any URL i read tells you WHAT hard disk types are used in the COOL tier of Storage Account Std V2. Also this is not about validation what SAP recommends. This questions is all about Azure Storage Account and nothing else.

SSD & another Azure region. SSD: Performance tier is only activated in SSD For HDD its not activaed since HDD has not premium tier and only standard tier. So SSD is the correct answer. Another Region: Due to GRS, its repliacated to another region.

https://www.sqlshack.com/different-azure-storage-types-file-blob-queue-table/ Depending on what you want to do with the storage, you can choose Standard which is on HDD or Premium which is on SSD. Obviously, the latter incurs a higher cost than the former.

Answer is HDD and GRS(to another region). Check the "Azure standard HDD storage" in the below url which clearly answers the question https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/planning-guide-storage#azure-standard-hdd-storage

Standard HDD are not supported by SAP for any Storage accounts. Minimum it should be SSDs.

First of all, it doesn't says anything w.r.t HANA database. For any SAP database, below is the link of support matrix storages. It says HDDs are not supported for any type of storage, although standard SSDs can be suitable for non-prod systems.. so, correct answer is Standard SSDs & GRS. https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/planning-guide-storage#storage-recommendations-for-sap-storage-scenarios

Answer is : Standard sold-state drives (SDDs), to another Azure region , In general, Azure standard HDD storage is not recommended and was used for demonstration purposes only. Recommendation is to use a minimum of Azure Standard SSD storage or Azure Premium Storage for production systems. https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/sap-hana-backup-file-level

I think HDD and another region. By the explanation of the Azure Storage Account : Standard storage accounts are backed by magnetic drives and provide the lowset cost per GB. I agree with that for SAP, HDD is not good, but it is for backup.

1. HDD (Explanation is below) 2. Another Region There are two kinds of Storage accounts: General Purpose Storage Account: A general-purpose storage account gives you access to Azure Storage services such as Tables, Queues, Files, Blobs and Azure virtual machine disks under a single account. It has two performance tiers: Standard storage performance tier which allows you to store Tables, Queues, Files, Blobs and Azure virtual machine disks. It’s backed by magnetic drives (HDD) and provide the lowest cost per GB. Premium storage performance tier which currently only supports Azure virtual machine disks. It is backed by solid state drives (SSD) and offer consistent low-latency performance.
