What is SAS and SATA?

What is an ATAPI that uses a narrow more reliable cable?

That sounds like a SATA device. SATA cables only use 6-7 wires. ATAPI is the standard for devices other than hard drives that also use the ATA command set and signals. Nearly all DVD burners, like most internal hard drives, use SATA these days. There is also SCSI Attached Storage (SAS), and it uses SATA cables and is electrically compatible with SATA, though with a different command set. There is no SAS DVD burner yet, but that is okay, since SATA devices will work with an SAS controller. The compatibility is only one way, meaning that while SATA devices work on SAS controllers, you cannot install a SAS drive with a SATA-only port.

How do you connect SAS drives to a SAS controller in a xw8600 when the sata cables don't fit into the SAS drive connector?

To connect SAS drives to a SAS controller in an HP xw8600, you need to use the appropriate SAS cables, as SATA cables are incompatible with SAS connectors. Ensure that you have SAS breakout cables that have the correct connectors for both the SAS controller and the SAS drives. Connect the SAS drives to the breakout cable, and then attach the other end of the cable to the SAS controller. Make sure the drives are properly seated and the controller is configured to recognize them in the system BIOS.

What is special about a SAS hard drive?

An SAS hard drive has many high performance advantages over a SATA drive. The main thing that makes it better is the speed. A typical SATA drive operates at 7200 RPM, yet a typical SAS drive operates at 10,000 or 15,000 RPM.

List two advantages of the SATA drive over the PATA drive?

a SATA hard drive can be connected to and controlled by a SAS hard drive controller

What kind of computer device is SAS HDD?

An SAS HDD is a type of hard disk drive that is used in computers. They are generally considered better than SATA hard disk drives and allow for faster processing speeds and data transfer.

Which interface is not typically used for an internal tape drive?

SCSI (Small Computer System Interface) is not typically used for internal tape drives, as most modern internal tape drives utilize SATA (Serial Advanced Technology Attachment) or SAS (Serial Attached SCSI) interfaces. SCSI was more common in older tape drive models, while SATA and SAS offer better performance and compatibility with current hardware systems.

What is the difference between a single port SAS drive and a dual port SAS dive?

The dual port is a separate feature from full-duplex. Dual porting provides a redundant data path, which performs two functions: 1) Allows the drive to operate at 6GB/s instead of the regular 3GB/s (port combining for superior performance). 2) Allows the drive to continue functioning if and when one port becomes nonfunctional (eliminates single point of failure). If dual porting were the feature that provided full duplex, neither of these functions would work, however all SAS serial interfaces are inherently full-duplex. Note also that SATA does not support dual ports or full duplex, even on a controller that supports both SATA and SAS drives. You must use SAS drives to have these features.

Will sata 2 run on sata 1?

Yes, SATA II (SATA 3 Gb/s) devices are backward compatible with SATA I (SATA 1.5 Gb/s) interfaces. This means that you can connect a SATA II hard drive or SSD to a SATA I motherboard, but the drive will operate at the lower SATA I speed. However, if you connect a SATA I drive to a SATA II interface, it will run at the SATA I speed as well.

What is difference between ide sata and scsi hard disk?

For years the parallel interface has been widely used in storage systems. The need for increased bandwidth and flexibility in storage systems made the SCSI and ATA standards an inefficient option. A parallel interface is a channel capable of transferring date in parallel mode - that is transmitting multiple bits simultaneously. Almost all personal computers come with at least one parallel interface. Common parallel interfaces include SCSI and ATA. SCSI(sku4zē) Short for small computer system interface, a parallel interface standard used by Apple Macintosh computers, PCs and many UNIX systems for attaching peripheral devices to computers. Nearly all Apple Macintosh computers, excluding only the earliest Macs and the recent iMac, come with a SCSI port for attaching devices such as disk drives and printers. SCSI interfaces provide for data transmission rates (up to 80 megabytes per second). In addition, you can attach multiple devices to a single SCSI port, so that SCSI is really an I/O bus rather than simply an interface. ATA(Also known as IDE) is a disk drive implementation that integrates the controller on the disk drive itself. ATA is used to connect hard disk drives, CD-ROM drives and similar peripherals and supports 8/16-bit interface that transfer up to 8.3MB/s for ATA-2 and up to 100MB/s (ATA-6). So, what do parallel interfaces have to do with SAS (Serial Attached SCSI) and SATA (Serial ATA)? A lot, actually. It is the architectural limitations of the parallel interfaces that serial technologies like SAS and SATA address. In contrast to multiple parallel data stream, data is transmitted serially, that is in a single steam, by wrapping multiple bits into packets and it is able to move that single stream faster than parallel technology. Serial Attached SCSI (SAS)Abbreviated as SAS, Serial Attached SCSI, an evolution of parallel SCSI into a point-to-point serial peripheral interface in which controllers are linked directly to disk drives. SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0Gb/s. In addition, SAS drives can be hot-plugged. Serial ATA (SATA) Often abbreviated as SATA, Serial ATA is an evolution of the Parallel ATA physical storage interface. Serial ATA is a serial link - a single cable with a minimum of four wires creates a point-to-point connection between devices. Transfer rates for Serial ATA begin at 150MB/s. Starting with SATA, it extends the capabilities of ATA and offers transfer rates starting at 150MB/s and, after years of development, has moved to the mainstream of disk interfaces. The successor the SCSI interface is SAS at speeds of up to 3Gb/s. Additionally, it also addresses parallel interface issues such as drive addressability and limitations on the number of device per port connection. SAS devices can communicate with both SATA and SCSI devices (the backplanes of SAS devices are identical to SATA devices). A key difference between SCSI and SAS devices is the addition in SAS devices of two data ports, each of which resides in a different SAS domain. This enables complete failover redundancy. If one path fails, there is still communication along a separate and independent path. Cables & Connectors Another big advantage of SATA over ATA is the cabling and connectors. The serial interface reduces the amount of wires needed to transmit data, making for much smaller cable size and making it easier to route and install SATA devices. The IDE cables used in parallel ATA systems are bulkier than Serial ATA cables and can only extend to 40cm long, while Serial ATA cables can extend up to one meter. In addition to the cabling, a new design of connectors is also used that reduces the amount of crosstalk between the wires, and the connector design also provides easier routing and better air flow. The Benefits of SAS & SATA in Storage Serial interfaces offer an improvement over older parallel SCSI (with a serial version) in storage applications and environments. These benefits include better performance, better scalability, and also better reliability as the parallel interfaces are at their limits of speed with reliable data transfers. SAS and SATA drives can also operate in the same environment while SCSI and ATA cannot. For example, using faster SAS drives for primary storage and offloading older data to cheaper SATA disks in the same subsystem, something that could not be achieved with SCSI and ATA.

What is the difference between 'sata' and 'ata' hard disk drives?

ATA = Advanced Technology Attachment and has speeds of up to 133 Mbps. Has a 40 pin connector. SATA = Serial ATA. Smaller connections and higher data speeds. See the attached link for a webpage with more info.The SATA host adapter is integrated into almost all modern computers. The difference is sata is 7 pin connectoe and ata is 40-44 pin
