In a 1 storage array for 1 or more hosts environment, the storage array will be the target and the host(s) will act as initiators.
In a multiple storage array environment each storage array can also act as an initiator when data replication is used. The sending port of the sending array is the initiator in that case.

1 storage array for 1 or more hosts environment , the storage array will be the target and the host(s) will act as initiators
at the first time of communication or it will be in same state for further communication..

I don't understand what you're asking. The host is never a target, but the storage array can be both. In normal operation where you only have 1 array, the array is the target.

As RRR explained already, Storage port will be the target and host HBA will be the initiator in a storage to host communication. It will be the same as long as the communication is there.

vipin i have a scenario that.. backup server is running with one of the hba connected to storage. the server is a client. so in that case it will act as target during backup... backup is now running with this configuration.. so if it maintain in overall communication how backup will occur ?? the server also able to access the storage. hope u understood the situation.

a lot of backup application will store data locally during the backup windows and then send it to tape. It sounds like in your scenario you are using SAN storage for the "cache" area.

can you rephrase your last question again, i don't understand if you are asking about backup server connectivity or backup client connectivity.

Dear Dynamox,
Yes,it is a SAN backup
I will explain ,before that
a lot of backup application will store data locally during the backup windows and then send it to tape. It sounds like in your scenario you are using SAN storage for the "cache" area.
is right they are using storage space as cache space
Problem that we are having only one HBA in the server, and we are using the same hba for data domain backup and emc storage
When ever we are doing any storage level activity backup is failing with a communication error
so we are assuming that
the communication between storage and server will be ,storage target and server initiator
and for the Backup solution Data domain will be initiator and server will target
is that the reason for this problem ,we need a clarifiaction before explain this to customer
advance thanks for your help

that very well might be the issues, best practice is to always segregate disk connectivity from tape/VTL. Could the customer drop another HBA in the server ?
