SAN: Lun assignment without zoning.

[sandeep-hp]

Can we assign luns to server without creating zone from any server. It can be done with hard zoning. Is any other way?

Yes connect your host directly to San ports:)
but why you want to skip zoning and what do you mean to say it can be done with hard zoning?

[Uwe Zessin]

LUN masking and zoning are complementary technologies and independed from each other.

Zoning should still be implemented, even if only one storage array is being used with several servers connected. Each server adapter should be in a separate zone together with the storage array - this prevents 'cross talks'.

Sorry over here San means if you connect your host directly to storage port by that way you can avoid zoning.. but this will limit your san to number of host connectivity.. in other cases if you go thrugh fabric zoning is mandtory.. you cant avoid that :P

[Uwe Zessin]

Of course you are free to use your own terminology ;-)

Over here, the term "San" is not being used. SAN is short for "Storage Area Network" and is not an acronym for a Fibre Channel / iSCSI storage array. A SAN includes one or more storage arrays, the network infrastructure (FC-/IP-based) and the servers.

Yes you can connect your server without zoning to the storage array.

Its Peer to Peer Topolgy.

[Uwe Zessin]

I think you mean "point-to-point topology".
The term "peer-to-peer" is usually used in a computer network, where clients directly talk to each other:

But watch out - on a QLogic adapter, "Point-To-Point" means talking fabric protocol on a connection to a Fibre Channel switch. Technically, this is true, because in that case the adapter has a direct link to the FC switch with no other components in the path.
