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.
PIOPS is supported for EBS higher than 500 GB size
B.
The maximum IOPS supported by EBS is 3000
C.
The ratio between IOPS and the EBS volume is higher than 30
D.
The ratio between IOPS and the EBS volume is lower than 50
I apologize for the confusion caused. The correct answer is:
D. The ratio between IOPS and the EBS volume is lower than 50.
The maximum IOPS to volume size ratio for Provisioned IOPS SSD (io1) volumes is 50:1. This means that the number of provisioned IOPS should be lower than 50 times the volume size. For example, if the volume size is 100 GB, the maximum number of provisioned IOPS allowed would be 5,000 (100 GB * 50 IOPS/GB = 5,000 IOPS).
So, in the given scenario, if the user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size, it falls within the allowed ratio of 50:1. Therefore, there is no issue with the ratio between IOPS and the EBS volume, and the correct answer is not mentioned among the options provided.
D. The ratio between IOPS and the EBS volume is lower than 50
For io1, the ratio between the I/OPS and the size of the volume is 50:1. That is if the volume size is 100 GB then it is able to afford 5,000 I/OPS at maximum.
On the other side for io2, its ratio is 500:1. That is if the volume size is 100 GB then it is able to afford 50,000 I/OPS at maximum.
outdated.
No correct answer here.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html
The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1 for io1 volumes, and 500:1 for io2 volumes
I am not sure what to answer for this question on May 10th.
30 is the old value
then it was 50:1 ratio
I am not sure if I did it right - but I tried to create one EBS Provisioned Io1
tried to create a volume with 4000 and no errors
------
screen details
Volume Type Provisioned IOPS SSD (io1)
Size (GiB) 100 (Min: 4 GiB, Max: 16384 GiB)
IOPS 4000 (Min: 100 IOPS, Max: 64000 IOPS)
Someone please respond - I am taking a test on 5/16 and I am not sure what to answer
An update for Nov 2020. There are two types of volume, io1, and io2.
For io1, the ratio between the I/OPS and the size of the volume is 50:1. That is if the volume size is 100 GB then it is able to afford 5,000 I/OPS at maximum.
On the other side for io2, its ratio is 500:1. That is if the volume size is 100 GB then it is able to afford 50,000 I/OPS at maximum.
One thing in common between those types is that the maximum I/OPS keeps 64,000 unchanged.
Answer is C (for old)
Now maximum is 50:1
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
