The inventors of SCSI were:

• Seagate Corporation and IBM
• Shugart Associates, and NCR Corporation
• Western Digital and Seagate Corporation
• Western Digital and Unisys Corporation

The SCSI Architecture Model-3 includes specifications for Serial Storage Architecture (SSA), Serial Attached SCSI, iSCSI, IEEE 1394 (FireWire) and:

• ATA and Serial ATA
• USB 1.x through 3.x
• PCI and PCIe
• Fibre Channel (FC)

Two interfaces that support hot plugging are USB and:

• IEEE 1394 (FireWire)
• Serial ATA
• PCIe
• Fibre Channel (FC)

Fibre Channel storage systems can be configured to use which of the following network components:

• Firewalls
• Routers
• Hubs
• Modems

Which of the following is the best choice for connecting high performance storage components within the data center:

• Parallel SCSI
• Firewire
• iSCSI
• Fibre Channel

The main reasons for the adoption of Internet SCSI (iSCSI) over Fibre Channel (FC) include:

• iSCSI is faster than FC
• iSCSI is easier to learn
• iSCSI uses standard copper cables
• iSCSI has no device number limit

A TCP Offload Engine

• connects an iSCSI Ethernet card to a Fibre Channel loop
• provides TCP connectivity to a Fibre Channel loop
• can serve as FC initiator or responder as required
• improves performance for iSCSI

The beneficial features of SATA include all of the following except:

• 300MBps transfer rate
• CRC error checking
• master-slave configuration
• cable length up to 1 meter

Specifications for the capabilities ad protocols of USB fall under the auspices of the:

• IEEE
• USB Council
• ISO
• USB Implementers Forum

USB 3.1 in Superspeed+ mode has a data transfer rate of:

• 1 Gbps
• 10 Gbps
• 20 Gbps
• 200 Gbps
