Azure Storage Space/Pool RRS feed

  • Question

  • Hi Team,

    Related to azure storage space, do we have lower limit on the size of physical disk to be used to create the storage pool.That is can we use 250 GB disk to create storage pool, will the performance for the pool having 250 GB disks will be different from the one having 1TB disks.

    Thanks & Regards

  • Hi Gaurav,

    You may use 250GB disk to create Storage pool also. However, please go through the following link which gives you much better understanding for Storage pool planning

  • Hi Gaurav,

    Did you mean that you want to create 250 GB disk using Azure storage as storage Pool ? If I am understanding right, you can do that. And the performance for the pool is the same as the 1TB disk. I suggest you could refer to this document about Azure Storage Scalability and Performance Targets:

    If I  misunderstood, please feel free let me know.

  • Hi Wil,

    Thanks for your response.Yes have created storage space combining 8 250GB disks but my application is behaving badly in terms of iops and ETL tiime is almost 7 times to what it was taking in the on premises environment.

    So now digging out into it as why am not getting theoretical iops even after creating the storage space.

    It is a BI application and am migrating to azure iaas.

    Regards

  • Hi Gaurav,

    Base on my experience, there is a 20,000 IOPS limit per storage account. If your 8 disks in one storage account, your 8 disks IOPS is not hitting the 20,000/8 IOPS. I suggest you could refer to Craig's blog form this link:http://blogs.msdn.com/b/mast/archive/2014/08/02/how-to-monitor-for-storage-account-throttling.aspx 

    And you also see this video http://channel9.msdn.com/Events/Microsoft-Azure/Level-Up-Azure-IaaS-for-IT-Pros/Deep-Dive-into-Azure-Storage-Blobs-DisksFiles-Tables-and-Queues

    If I misunderstood, please let me know.
