Hi Chris,  Re: 1.  You can't mix a new array with an array that's End-of-Life (EOL).  You can add it in order to remove the PS5000 but you can't leave it in the same group for production.   Re: 1a.  No, you can't merge groups.  Once an array is a member of a group it can't be added to another without first being reset, which removes all the data.   Re: 2.  Performance Load Balancer (PLB), has nothing to do with this process.  That only affects volume location when you have a R10 member in a pool, and the other member(s) are using a different RAID level.   Re: 2a.  Depending on the interconnect capacity will determine if there's a performance impact.  But any servers connecting to that new member will have to go over that interconnect.     Re: 2b.  No.  The network balancing is still in affect.   Re: 2c.  If you are still talking about PLB, then it's not applicable here.  If the two members are in the same pool, they will split the volumes across the members automatically.   Running a group over a WAN usually doesn't work very well.   That's been my experience anyway.    Please provide some more details on how they would be interconnected.    Regards,   Don 
We currently have a 5000X EQL and would like to add a new 6100X EQL to the same SAN group.  But the problem is they are currently sitting in different physical buildings (they will be consolidated to one, but that is not right now).  We are in the process of getting the new 6100X setup, but need to know a couple of things. Any insight on this would be very helpful. Thanks, Chris
