Amazon documentation says that the number of EBS volumes that can be attached to a Linux EC2 instance is essentially unlimited, but it seems the number of potential available device names is limited to:

/dev/sd[f-p][1-6]

Which is 11 * 6 = 66 volumes

What I want to do is have an EC2 instance that has thousands of EBS volumes attached, and want to know if this is possible?

Thanks! Chris

Since EBS volumes are network attached storage, you will likely saturate the network interface before you can effectively use all those volumes. 4-8 volumes is more of a practical limit if you want to maximize I/O.

You can not attach multiple EBS volumes to an single EC2Instance .But you can attach multiple volumes to an ec2instance .
