access the DS5020 readme files on the Web.
FC-SAS defined
In this document, the term FC-SAS refers to a SAS drive with a FC-SAS interposer
that translates the SAS drive interface to a FC protocol interface. Contrast with
“SAS defined”.
Fibre Channel defined
Fibre Channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre Channel is a high-speed data transport technology that
is used for mass storage and networking.
Using a Fibre Channel arbitrated loop (FC-AL), more than 100 Fibre Channel
devices can be supported, compared to 15 small computer system interface (SCSI)
devices. The Fibre Channel connection speed from the storage subsystem to
storage expansion enclosures is 4 Gbps, and enables data transfer rates up to 400
Mbps half-duplex and 800 Mbps full-duplex on optical interfaces.
iSCSI defined
The Internet Small Computer System Interface (iSCSI) is an IP-based standard for
linking data storage devices over a network and transferring data by carrying SCSI
commands over IP networks.
SAS defined
The Serial-attached SCSI (SAS) is a data-transfer technology that moves data to
and from computer storage devices such as hard drives and tape drives. SAS uses
a point-to-point serial protocol instead of the traditional parallel SCSI bus
technology. In this document, the term FC-SAS refers to a SAS drive with a
FC-SAS interposer that translates the SAS drive interface to a FC protocol
interface. See “FC-SAS defined”.
