What is the difference between SCSI and SAS?
SCSI uses a parellel communication chain and SAS uses serial Point to Point communication
Difference between single ended scsi and differential scsi?
single ended scsi is a method of transmitting electrical signals over wires. one wire carries a varying voltage that represent a signal, while other wire is connected to a ground. single emded scsi cables are of 6m-1.3m long. Differential scsi is a method of transmitting information electrically by means of 2 complementary signal pairs sent on 2 separate wires.
What is the difference between sda and hda in Linux?
Historically, hda was used for IDE drives and SDA was used for SCSI drives. Today, regardless of physical interface, all drives are treated as SCSI devices.
What is the difference between narrow SCSI and wide SCSI?
The wide SCSI-2 uses a wider data path & emdash;16 bit rather than the normal 8 bit & emdash; for the same 10 Mbps. Combining both fast and wide can, in theory, reach 20 Mbps.
What is scsi harddisk?
SCSI (Small Computer System Interface) is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect other devices, including scanners and CD drives. An SCSI drive is usually referred to a disk drive that uses the SCSI standard interface and commands to connect and transfer data to/from the computer.
Why is there confusion about the EIDE and SCSI drive-interface standards?
Why is there confusion between EIDE and SCSI drive interface standards
You install a SCSI adapter on your system to control both external and internal devices how will you achieve this?
Most SCSI cards have both internal and external connectors. I don't believe that software will know the difference between a device hooked up externally and one hooked up internally.
What is the Difference between SCSI and RAID cards?
RAID and SCSI are completely different things.RAID = Redundant Array of Independent Disks.SCSI = Small Computer System Interface.SCSI is the type of interface that exists on the physical hard drive for connecting it to a host device. The host, be it a computer or a RAID would need to also support the SCSI interface.RAID is a cluster of hard drives which work together as a storage system. RAID could use any type of interface, including SCSI.
Which version of scsi is known as fast scsi?
SCSI-2
Which two SCSI connectors might be used with narrow SCSI?
DB25 SCSI connector50 pin SCSI connector
Which SCSI is known as fast SCSI and has a 68 pin connector?
SCSI 3
SCSI bus can support up to how many devices simultaneously?
SCSI, Fast SCSI, Ultra SCSI, Ultra2 SCSI: 8 devices Wide SCSI, Fast Wide SCSI, Ultra Wide SCSI, Wide Ultra2 SCSI, Ultra3 SCSI, Ultra160 and 160+ and Ultra320 : 16 devices Of course, the number of devices supported depends not only on protocol limitations, but cable length, number of cables used, etc.
