while native Fibre Channel
LTO 3 drives have 2-Gb/sec.
The member-led working groups and committees focus on creating and championing the Fibre Channel
technology roadmaps, targeting applications that include data storage, video, networking, and storage area network (SAN) management.
Protocol: SCSI- the application doesn't see any difference, which is key, as almost all applications want to talk to external storage using SCSI commands, so the fact that Fibre Channel
and iSCSI allow you to transport SCSI commands makes SANs usable to existing applications.
Subsystems using the same model drives, but with Fibre Channel
interfaces, have achieved over 30,000 for the same kind of I/Os, simply by taking advantage of this full duplex feature (and this was at 1GB/sec).
End-to-end 2Gb Fibre Channel
functionality is presently available with Eurologic's SANbloc JBOD network storage system.
At the same time that these vendors eagerly claim iSCSI leadership and iSCSI strategies, they are careful to position their iSCSI devices at the low-end of the market to protect their high-end Fibre Channel
also requires hardware and software to support the proper formatting of data packets and other functions such as controlling the flow of the packets, correcting any errors in transmission, and (in the case of TCP/IP) reassembling packets in the proper order when they arrive at the server.
Fibre Attached Technology Adapted drives will offer capacity up to 250 gigabytes with a dual-port, 2GB/second, Fibre Channel

Because iSCSI is a native IP-based protocol, data can be transported over the existing Ethernet infrastructure rather than through Fibre Channel
or SCSI cabling.
Customers have the option of taking advantage of four external Fibre Channel
ports or using the adapter as a standard dual-channel product.
already preserves the SCSI command set intact, which allows it to interface with SCSI-enabled storage devices.
