There's never been a limit on number of hosts connecting to a volume.  (up to the max connections to that pool)   So you could have 1024 connections to a single volume if you wanted to.  Prior to 7.0.x firmware, each volume could have up to 16 ACL entries.  They could be IP, IQN name or CHAP.  (or any combination)    With 7.0 you can create a "super" ACL which doesn't have the 16 ACL limit.  For clusters it's very easy to set a CHAP username for the cluster volumes, so you only need one ACL for any number of cluster nodes.  That's what I use for ESXi.   I create a CHAP account for each set of clusters I have.  I.e. ESXi v4.1, 5.0, 5.1, 5.5.   To add a node to the ESXi v5.0 cluster I only need add the proper CHAP username / password on the ESXi node.    CHAP also has the benefit of preventing IP or IQN spoofing.   Regards, 
Hello, I know in past revisions of EqualLogic there have been limitations of how many hosts could be on a volume. Does anyone know if this still exists? We are looking at a Volume ACL having 10+ hosts? thank you.
