Amazon EBS announces up to 128 volume attachments per EC2 instance
Today, with the launch of M7i instances, customers can attach up to 128 EBS volumes to an EC2 instance. By comparison, previous generation M6i instances allow up to 28 EBS volume attachments to an EC2 instance. The higher volume attachment limit enables customers to increase storage density per EC2 instance, so that they can host larger applications per instance or reduce total compute cost by improving their resource utilization. With this launch, customers can also take crash-consistent snapshots for up to 128 EBS volumes attached to a single EC2 instance.

With a higher number of volume attachments, customers running containerized applications that require dedicated persistent storage can now host up to 127 pods or tasks per EC2 instance, enabling them to scale more cost-effectively on AWS. Customers running databases on AWS use larger sized EC2 instances as their databases continue to grow, and, with a higher number of volume attachments, they can fully utilize the memory and vCPU available on these powerful EC2 instances as their database storage footprints grow.
Starting with M7i instances, support for a higher number of EBS volume attachments is generally available in all AWS commercial regions and locations where these new EC2 instance types are available.
