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.
Outdated.
An io1 volume can range in size from 4 GiB to 16 TiB and you can provision 100 up to 32,000 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 640 GiB in size or greater allows provisioning up to the 32,000 IOPS maximum (50 × 640 GiB = 32,000).
