Iscsi discovery configuration and saving of nodes

Scenario: On Suse, the device discovery results are recorded in the/etc/iSCSI/node, which is effective upon startup and restart. In the RedHat system, the node found by the device is recorded in/var/lib/iSCSI/nodes. This file is created by the iSCSI initor program and can be found in/etc/init. d/iscsid service, view the START process, use this file. Fr

Iscsi workflow target and initiator

As enterprise-level data grows exponentially, traditional centralized storage solutions cannot meet their storage requirements. Therefore, the storage area network (SAN) technology is widely used, however, there are shortcomings such as short distance, expensive price, and complicated construction. The iscsi-Based IP Storage technology is a new network storage technology that integrates the IP network technology into storage I/O, what are the advantag
