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
Suggested Answer:A🗳️
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.
The description is Invalid or may be older update. It had been calcuated based on 30 or lower IOPS Provision capacity.
https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ebs-volume-types.html#EBSVolumeTypes_piops.
An io1 volume can range in size from 4 GiB to 16 TiB.
If Nitro-based Instances then IOPS Can be 100 IOPS to 64000 IOPS.
If Non Nitro-based Instances then IOPS Can be 100 IOPS to 32000 IOPS.
The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1.
As per question : 100GB so Max IOPS can be 5000.
