Enhancements for the iSCSI

["Nelson Nahum" <nnahum@store-age.com>]

I think that the iSCSI is a special opportunity to enhance the current SCSI
protocol especially it networking capabilities.
SCSI was designed with the concept of Initiator for the HBA and Target for
the devices. The Initator sends commands to the Targets that are passive.
But the networking world supposes every one talking with every one. The fact
that iSCSI is implemented over TCP/IP can help to develop these enhacements.

Modern SAN appliances need to "talk" with the storage devices but also need
a way to update information in the HBAs in a asynchronous manner.

My questions are the following:

1 - Is iSCSI designed in such a way that every Target can also be Initiator
and viceversa or it supposes different charasterisitics (memory, CPU power
etc.) between the Initiator and the Target?

2 - Is possible to add asynchronous events that the Target could send to the
Initiators at any time?

3 - Another important enhancement could be the possibility to "broadcast"
information to many iSCSI devices or HBAs.
