Show Suggested Answer

Suggested Answer: BDE 🗳️
B: By carrying SCSI commands over IP networks, the iSCSI protocol enables you to access block devices from across the network as if they were connected to the local system. COMSTAR provides an easier way to manage these iSCSI target devices.
D: Common Multiprotocol SCSI TARget, or COMSTAR, a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.
E: One IP port can handle multiple iSCSI target devices.
Incorrect answers:
Here are the current limitations or restrictions of using the iSCSI initiator software in Oracle Solaris:
* Support for iSCSI devices that use SLP is not currently available.
* iSCSI targets cannot be configured as dump devices.
* Transferring large amounts of data over your existing network can have an impact on performance.
