Management Path network connection
Hardware Setup
Each VTrak E5000 Series controller has two 1000BASE-T Ethernet ports for management over the network.
To establish the management path network connection:
1. Attach one end of an Ethernet cable to the network connector or standard NIC in the Host PC. Attach the other end of the Ethernet cable to a port on a standard network switch.
2. Attach one end of an Ethernet cable to a port on the same network switch. Attach the other end of the
Ethernet cable to one of the Management Ports on a controller. Use another Ethernet cable to connect one of the Management Ports on the remaining controller.
If you have multiple VTrak E5000 Series subsystems, repeat steps 1 and 2 as needed.
Note
All RJ-45 network management ports on a VTrak E5000 Series subsystem share the same Virtual IP address. The default Virtual IP address, 10.0.0.1, applies to all RJ-45 network ports. If you change the
Virtual IP address, the change applies to all RJ-45 ports.
Fibre Channel SAN connections
The Fibre Channel data network for the VTrak E5000 controllers requires the following items:
• A Fibre Channel connection in each host PC or server
• An SFP transceiver for each connected FC port on the subsystem
• A Fibre Channel switch
• Fiber Optic cabling
• A network switch
Important
For a list of supported HBAs, Switches, and SFP transceivers, download the latest compatibility list from PROMISE support: http://www.promise.com/support/.
