What are Azure Storage Limits?

Microsoft Azure Storage is a cloud storage solution that offers full functionality, protection, consistency, adaptability, and resilience. Azure storage consists of five services: Azure NetApp Files, Azure Blob Storage, Azure Queues, Azure Tables, and Azure Disks.

Azure Storage will send error code 503 (server busy) or error code 500 when your application reaches the workload limit for any Azure Storage service (timeout).To avoid problems or outages, keep an eye out for these error codes and make sure your application adheres to the restrictions. Limits can, of course, impair the performance of Azure services.

Limits are not directly enforced by Azure, but rather by several software components inside of your application. These components can be implemented in different ways:

Aufbau: In this approach, you have a single instance that handles all queries submitted over an API. At some point during its lifespan, it will decide to either drop connection or violate a limit. Regardless of which it chooses, every request will result in an error code – usually 500 or 503.

In a nutshell, Azure Storage limits allow us to make sure that the service is available to everyone, but at the same time stay within the budget. Microsoft Azure Storage limits allow us to make sure that the service is available to everyone, but at the same time stay within the budget.

Azure Storage Limits

NetApp Files in Azure

Supervisors can manage SMB file shares through the cloud using Azure NetApp Files, a NAS file sharing storage solution. These shares, like other Azure storage offerings, can be set up as part of an Azure storage account. Storage accounts, shares, and files are the three types of Azure NetApp Files constraints.

Here, there are two types of limits; flexible resource limits and hard resource limits. There is also another limit in Azure NetApp files that is called max files. It determines how many files a customer can store per single volume.

Azure storage account (basic)

Your Azure storage account is the primary resource of Azure NetApp Files Sharing. A memory account is an Azure collection account that enables you to store data using a variety of storage services, including Azure NetApp Files. Azure storage accounts, like other

Azure resources can be provisioned and managed by access management services. Access management, which was formerly known as identity and access management (IAM), supports authentication and authorization of Azure resources and provides security enforcement.

An Azure storage account is a container that stores data you have saved to your file shares. A file share is a share point on a file-based network, such as a NAS device or other SMB server. When you save data to the file shares, it’s stored in Azure storage as an azure data object (Azure Data).

  • • This restriction relates to accounts with the “general-purpose v2” or “blob storage” account types. With RA-GRS/GRS, the threshold is 20 Gbps if you have a “general-purpose v1” account. If you use LRS/ZRS it is 30 Gbps.
  • • If your storage account employs RA-GRS/GRS, this limit applies. The limit for LRS/ZRS is 15 Gbps if the above doesn’t apply for.Th
  • • The number of blob containers, blobs, entities, queues, tables, file shares, and messages is unrestricted.

Limits on premium FileStorage accounts

Premium FileStorage accounts are optimized for workloads that require fast response time, superior efficiency, and high IOPS. With a premium version, there is no restriction on the number of file shares you can create. The storage size of a Premium FileStorage account is set at 100 TB.

Limitations related to file shares

When it comes to this section, we will divide it into two and see it in detail.

Standard file shares

  • • Minimum share size: N/A
  • • Maximum share size: 5 TB by default, can be increased up to 100TB
  • • Maximum file size: 1 TB
  • • Maximum IOPS: 1,000 IOPS*
  • • Maximum number of share snapshots: 200
  • • Maximum directory/filename length (chars): 2,048
  • • Maximum stored access policies: 5
  • • Target throughput: 60 MB/sec

Premium file shares

  • . Minimum share size: 100 GB
  • • Maximum share size: 100 TB
  • • Maximum file size: 4 TB
  • • Maximum IOPS: 100,000 IOPS
  • • Maximum stored access policies: 5 • Target throughput: Ingress 4,136 MB/s, Egress 6,204 MB/s
  • • Maximum number of share snapshots: 200
  • • Maximum directory/filename length (chars): 2,048
  • Remember in a standard file share, you can increase the maximum IOPS to 10,000. When it comes to the target throughput, it has the capacity to go near 300 MB/s.

Azure NetApp Files Sync

Azure NetApp Files Sync is a platform that is designed for a specific reason; maximizing scalability. Even though it does this task, it has its own limits. These limits are placed into two categories and are both defined by different groups.

  1. Hard limit

This limit type is coined by File Sync technical architecture. It entails three main limits. These are:

  • • Up to 100 Sync Services per region, up to 200 Sync Groups per Sync Service, up to 99 servers per Sync Service with up to one server endpoint each.
  • • There is no cloud endpoint per sync group that is more than one.
  • • The directories found here are many. They can go up to 5 million.
  1. Soft limit

This second type of limit is coined by Microsoft testing and practical experience. Just like the above one, these also hold three limits.

  • • The maximum size for a single file is 100 GB.
  • • The number of directories found here is 20 times more than in the hard limit. Putting it in numbers, there are 100 million directories per sync group.
  • • There are about 50 servers per sync group.

Blob Storage

This Azure file is a Microsoft Azure service that deals with storing binary files. Examples of such files are texts, images, and videos. These blobs are also known as containers which are stored structures.

Azure Queue Storage

This is a basic Azure file with a FIFO structure. For those of you that don’t know FIFO is first-in-first-out. This FIFO structure is composed of three main categories. These are:

  • • Storage Account: this is the highest level. It includes all devices that store Azure.
  • • Queue: this one is a series of messages.
  • • Message: this is one of the series of messages in the queue. This message may contain a specific message. This message is in the form of a text string, an array of bytes, etc.
  • Limits of each element in the Queue Storage system.
