Abstract
An aggregator device provides an iSCSI client with a list of storage areas which are offered by a single aggregated network array. The storage areas on the list are provided by multiple data storage systems and are accessible by the client using data paths which are out-of-band with the aggregator device. The aggregator device further receives an iSCSI login request from the client. The iSCSI login request identifies a particular storage area on the list of storage areas. The aggregator device further generates and sends an iSCSI login response to the client in response to the iSCSI login request. The iSCSI login response includes a network address of a particular data storage system of the multiple data storage systems which provides the particular storage area to enable the client to directly access the particular storage area using a data path which is out-of-band with the aggregator device.
