Hardware Configuration Rules

An ExtremeZ SAN installation must follow these hardware configuration rules:
Each client and server system must have a SANergy hardware lock (dongle) connected to the
parallel port.
Each client and server system must connect to the same TCP/IP Ethernet network.
All client and server systems and Fibre Channel disk arrays must connect to the same Fibre
Channel hub.
Only one client or server system may connect to a GBIC port module in the Fibre Channel
hub.
Only one Fibre Channel disk array may connect to a copper GBIC port module in the Fibre
Channel hub. "Y" cables are not supported for Fibre Channel disk arrays.
No more than 125 devices a combination of client and server systems and individual Fibre
Channel disk drives may connect to a single hub.
All devices connected to the hub are logically on the same Fibre Channel Arbitrated Loop
(FC-AL).
Cascading multiple hubs, or combinations of hubs and switches, are not supported.
You must have all of the hardware connected and operational before you install the SANergy
software required to manage an ExtremeZ SAN installation, as follows:
Networking must be set up and operational on all client systems and on the server system (also
known as the meta-data controller or MDC). Each system must have a valid Internet Protocol
(IP) address and subnet mask, a unique computer name, and the name of a Windows NT
networking workgroup. See the SANergy documentation for more information.
Client and server systems must be connected to the storage systems. For an ExtremeZ SAN
system, make sure all connections between the client and server systems, the hub, and the disk
arrays are in place. See "Typical Hardware Connections" in this chapter for more
information.
Disk drives must be installed in the disk arrays. See the Fibre Channel documentation for
more information.
