A user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size. AWS does not
allow the user to create this volume. What is the possible root cause for this?
A.
The ratio between IOPS and the EBS volume is higher than 30
B.
The maximum IOPS supported by EBS is 3000
C.
The ratio between IOPS and the EBS volume is lower than 50
D.
PIOPS is supported for EBS higher than 500 GB size
Explanation:
A provisioned IOPS EBS volume can range in size from 10 GB to 1 TB and the user can provision
up to 4000 IOPS per volume. The ratio of IOPS provisioned to the volume size requested should
be a maximum of 30; for example, a volume with 3000 IOPS must be at least 100 GB.

We are pleased to announce that the Amazon EBS Provisioned IOPS volumes maximum IOPS:GB (input/output operations per second to Gigabytes) ratio has been increased from 10:1 to 30:1. Prior to this change, customers could provision up to 1,000 IOPS for a 100 GB volume. Now, they can provision up to 4,000 IOPS for a 133 GB volume, enjoying greater flexibility in how they configure Provisioned IOPS volumes.
Provisioned IOPS volumes are designed to provide predictable, high performance for I/O intensive workloads such as databases, distributed file systems and other enterprise applications. Customers can provision up to 1 TB and 4,000 IOPS per Provisioned IOPS volume. For more information on using Amazon EBS Provisioned IOPS volumes, please refer to the Amazon EC2 Developer Guide.

An io1 volume can range in size from 4 GiB to 16 TiB and you can provision 100 up to 20,000 IOPS per volume. The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1. For example, a 100 GiB volume can be provisioned with up to 5,000 IOPS. Any volume 400 GiB in size or greater allows provisioning up to the 20,000 IOPS maximum.
The throughput limit of io1 volumes is 256 KiB for each IOPS provisioned, up to a maximum of 320 MiB/s (at 1,280 IOPS).
