A standard storage account has an total request rate limit of 20.000 IOPS per storage account. The minimum disk throughput is 1 MiB. ; To see general limits on Azure VMs, see Azure subscription and service limits, quotas, and constraints. Balanced CPU-to-memory ratio. For information on using the REST API to query for VM sizes, see the following: Learn more about how Azure compute units (ACU) can help you compare compute performance across Azure SKUs. IOPS Performance depends on VM size. Each Azure Virtual Machine type is limited by a number of disks (total storage size), a maximum IOPS (IOPS) and a maximum throughput (Throughput). (8 disks = 8x500 IOPS). – David Makogon Apr 27 '15 at 12:43 You are correct. There is a potential risk that this VM has a bottleneck of IOPS even though each of the disks has sufficient IOPS capacity to maintain their operations. The reasoning is that each VM size has a limit for throughput. The Dv2-series is about 35% faster than the D-series. Sounds like you need to use the "Large" size in your template to provision an A3 Standard VM. Waiting that, I would create a separate volume on top of storage spaces (using as many disks as the VM size allows) in order to get max iops. DCv2 series instances enable customers to build secure enclave-based applications to protect their code and data while it’s in use. Having used Azure for some time now, I'm well aware of the default 20,000 IOPS limit of an Azure Storage Account. MS advice to me while working the ticket was to check the throttling metric on the account under file share. Good for medium traffic web servers, network appliances, batch processes, and application servers. So if you have a VM that has a limit of 10,000 IOPs and you are using a disk configuration that is capable of 20,000 you will only be able to achieve 10,000. D Series – D13, D14, D16. Esv3, Ev3, Easv4, Eav4, Ev4, Esv4, Edv4, Edsv4, Mv2, M, DSv2, Dv2. General purpose VM sizes provide balanced CPU-to-memory ratio. So if you have a VM that has a limit of 10,000 IOPs and you are using a disk configuration that is capable of 20,000 you will only be able to achieve 10,000. These new VM sizes will have 50% larger local storage, as well as better local disk IOPS for both read and write compared to the Dv3/Dsv3 sizes with Gen2 VMs. Therefore, for a DS1 Size VM the maximum IOPS at any given time cannot exceed 3200 IOPS. Great for relational database servers, medium to large caches, and in-memory analytics.
