Planning the Network Configuration
The following sections provide different possible network configurations and
help you plan for the implementation of Dell™ PowerVault™ NX1950 cluster
solution with Dell|EqualLogic
PS Series storage.
Considering the Network Design Structure
Implementing the correct networking infrastructure is essential to
trouble-free operation of your PowerVault NX1950 cluster solution. This
section provides guidelines for designing networks for use with a cluster.
Typically you have a minimum of three networks in use:
• One or more data networks for applications— These are referred to as
public networks. A data network can be made redundant using Network
Interface Card (NIC) teaming or by using multiple interfaces on separate
subnets.
• Heartbeat network— This is referred to as a private network. NIC teaming
cannot be used on the heartbeat network.
• Storage area network (SAN)— The SAN can be made redundant by use of
Microsoft’s multipath I/O (MPIO). Multipath I/O provides more
intelligent, SAN-integrated load balancing capabilities.
