According to the AWS doc(https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_Limits.html) Aurora's total instance storage per region is 100,000 GB(100TB).

And It is said that the aurora cluster is automatically scaled up to 128 TiB.

If I create 4 aurora clusters in RDS and one cluster is scaled up to 128 TiB, does an error occur when scaling up the other 3 clusters?

Or is it possible to scale up all 4 clusters to 128 TiB each?(Are total instance storage per region and Aurora Volume separate?)

I would be grateful if there is any document I can refer to.

CodePudding user response：

100TB is the default limit for Aurora storage per region. That means you won't be able to scale up any single instance to the maximum 128TB, in a single region, because that would be more than the default limit.

Or is it possible to scale up all 4 clusters to 128 TiB each?(Are total instance storage per region and Aurora Volume separate?)

No, that would be 512TB of Aurora storage in a single region, which would be more than the default limit of 100TB.

If your combined storage of all Aurora instances in a single region is going to be more than 100TB, you have to fill out a quota increase request, to get the limit raised on your account.
