Creating an iSCSI target
iSCSI is an industry-standard protocol that implements block storage over a TCP/IP network. With iSCSI, the server, or initiator, provides a volume shared via iSCSI. Effectively, the shared volumes are iSCSI logical unit numbers. The iSCSI client then sees that disk as locally attached. From the iSCSI client, you can manage the disk just like locally-attached storage.
Windows Server 2019 includes both iSCSI target (server) and iSCSI initiator (client) features. You set up an iSCSI target on a server and then use an iSCSI initiator on a client system to access the iSCSI target. You can use both Microsoft and third-party initiators and targets, although if you mix and match, you need to test very carefully that the combination works in your environment.
With iSCSI, a target is a single disk that the client accesses using the iSCSI Client. An iSCSI target server hosts one or more targets, where each iSCSI target is equivalent to a LUN on a Fiber Channel SAN. The iSCSI...
