Elastic Block Storage (EBS)

Question 1

For io1 volumes what is the ratio of provisioned IOPS to requested volume in size (in Gib)?

Answer 1

The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1 for io1 volumes.

• For a 100 GiB volume size, max IOPS possible is 100*50 = 5000 IOPS.
• For a 200 GiB volume size, max IOPS possible is 200*50 = 10000 IOPS.

Question 2

For io2 volumes what is the ratio of provisioned IOPS to requested volume in size (in Gib)?

Answer 2

The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 500:1 for io2 volumes.

• For a 100 GiB io2 volume can be provisioned with up to 50,000 IOPS.

Question 3

For gp2 volumes what is minimum volume size to hit the max IOPS?

Answer 3

A 5.3. TiB volume will hit the maximum of 16,000 IOPS

Question 4

Can you can attach an EBS volume to a EC2 instance in a different Availability Zone?

Answer 4

No, you can attach an EBS volume to any EC2 instance in the same Availability Zone.

Question 5
