How many individually functioning EBS drives ( non-raided ) can I connect to a single Amazon EC2 server running Linux CentOS? I can't find a value in the EC2 or EBS manuals. Are there any other drive limitations I should be aware of with EBS?

Remember, EBS goes out over the network, so it's limited to your 1Gbps or so. –  ceejayoz Feb 13 '12 at 18:57

Some people have been able to attach 40 EBS devices to the same instance using RAID (see http://alestic.com/2009/06/ec2-ebs-raid)

You could probably attach more than 40, but be aware of the device names limitations, since according to EC2 documentation these are the only devices available for external EBS drives on Linux instances running xvd drivers:

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