You can find much of the information on the pools in the VNX Guide, Managing Volumes and File Systems with VNX AVM.  This covers much of what you're looking for.  1. A System Pool is a pre-defined pool.  It consists of disks that match one of the system-defined AVM (automatic volume management) pools.  The system-defined pools do not normally have advanced data services, such as (auto-tiering or VNX compression) enabled.  A Mapped Pool is a dynamically-created pool.  It consists of LUNs that have advanced data services (such as auto-tiering or VNX compression enabled.  2.  Yes.  You can replicate from one type of disk to another, the same way you can replicate from one pool to another.  If you use the Unisphere Replication Wizard, it will list the available pools at the destination VNX.  You can also specify the destination pool (or filesystem) from the CLI as well.  3.  The Datamover Interconnect only requires the IPs to be in the same VLAN for replication purposes.  For example, if the primary VNX has interfaces on VLANs 10, 20 and 30, the secondary VNX needs to have an interface on only one of those VLANs for replication to work.  HOWEVER, if your clients expect to reach your secondary VNX on the same VLANs (IPs), you will need to provide the same VLAN to the secondary VNX.  So, in your example, if your NFS exports are on VLAN A, your secondary VNX needs a port on VLAN A to offer them up to clients on the same IP addresses.  However, if you intend to update DNS or you have static /etc/hosts files on your clients, you may not need to provide those VLANs.  At one customer site, the secondary VNX had half the VLANs the primary VNX had.  However, in the event of a failover, the customer needed to use a VPN to access the DR site, which routed the clients to the right VLAN.  Let us know if that helps!  Karl
Hello Friends,  I am working on File level replication (only NFS exports) from primary VNX to secondary VNX,  Below are my questions  1. In storage pools for file, what is the difference between type "System and Mapped" pool ?  2.In our environment Primary VNX has 2 pools for file, SAS & SATA, both are of type "System". There are 7 File Sytems the has been created either on SAS or SATA pool. These are the file systems that need to be replicated to secondary VNX. In secondary VNX, already there is a storage pool for file and of type "Mapped pool" and enough free space is available to accommodate the file systems from primary VNX . Is it possible to replicate the file systems from primary to secondary VNX with different types of storage pools for file?  3. Set up a new Data Mover Interconnect : In the interfaces field where we need to select an IP address to make available to local side of the interconnect and IP addresss for Peer side of an interconnect, i believe both the IP's need to be in same VLAN, am i right? Is it also necessary those IP's need to be in same VLAN of other ineterfaces (for example the interface used for NFS exports)?   Thanks Dino
