LocalStorage. Upper limit size?
LocalStorage. Upper limit size?
- What is the maximum valid value of "LocalStorage sizeInMb" parameter? I.e. what is the maximum size of the local storage?
Réponses
- Today, there is a limit of 20GB.
Do you need more than that?

- If I may clarify, my understanding is that LocalStorage is the non-persisted Azure File I/O space that is available to to each instance of your application. Apart from being unpersisted, this space is not accessible to any other instance of your tenant except the one that created it. That space is 20 GB for that instance.
As for the Azure Storage Space (particularly Table Storage/Blob storage), the size is unbounded for now (as much as I know). The sql express limit may or may not be directly applicable depending on how development storage implements the correspondence. Again, you can use the local development storage with other versions of SQL Server that don't have the 4GB limit.
That said, a good advisory that originates from the SQL Data Services team is to limit cloud DB data sizes to 100GB to facilitate easy house-keeping: eg, the need to quickly bring up a copy of an instance if one goes down.

SQL Express has a 4gb limit (if I'm remembering right). So that would likely be the limit for development storage?
- The 20GB is the local disk storage that you can get with every role instance. It is unrelated to the local development store that ships part of the SDK.

I would like to process big files in Azure. The processing task requires numerous read-write operation. I would like to implement the local disk-based cache. 20 GB should be enough space for my tasks.
In the meantime, I found the information that CTP offers the following type of VM: 64-bit Windows Server 2008, 1.5-1.7 GHz CPU , 1.7 GB Memory, 250 GB transient local storage. Why do I get only 20GB (less than 10% of available storage)?Mikhail
- These limits are there to ensure we will have fair resource allocation between the VMs and allow us to test the algorithms without impacting the users. In the future we will provide more available local storage to the user's process.
