Ultra-320 SCSI Internal Interface Card for PCI-X

Find Out More About Ultra-320 SCSI Internal Interface Card for PCI-X

Small computer systems interface (SCSI) is a microprocessor-controlled smart bus that lets you add up to 15 peripheral devices to your computer. Whether you want to connect an external hard drive, printer, or scanner, SCSI internal interface cards let you attach the devices you need to accomplish your goals. Designed for PCI-X, it supports higher clock speeds and bandwidth needs on desktop computers and servers.

There are several types of Ultra-320 SCSI internal interface cards for PCI-X. The types and brands they come in as well as some of their features are listed below:

• Brands: Choose from Adaptec, Dell, HP, IBM, Intel, LSI, and Tekram.
• External interfaces: Opinons include SAS, Ultra2, Ultra-320, and Ultra.
• Interface card type: Choose from RAID and SCSI Cards.
• Internal interfaces: Choose from eSATA, Fast, Fast-Wide, Optical LC, PATA/IDE/EIDE, SAS, SATA I, and SATA II. Other options include SATA III, SCSI-1, SFP, Ultra2, Ultra-320, Ultra3, Ultra, and Ultra Wide SCSI-3.
• Type: Options include non-RAID controller card and RAID controller card.

Often used in mainframes, PCs, servers, and workstations, this technology allows you to add drives for scanners, CD-Rs, DVD, Zip, and more along with external hard drives all to one SCSI cable chain. It's also useful in network servers where multiple hard drives can be established in a RAID configuration. In that, if one drive falters, a new one can replace it or it can simply be removed in what's called hot-swapping.

These drives can be installed in a PC that already has one or more IDE disk drives, one of which will remain the boot drive. These drives then offer extra storage space. The default boot device, even if one of these hard drives is installed and configured as device number 0, is always an IDE device. If an SCSI drive and an IDE CD-ROM drive are on the same computer, the system will always boot to the CD-ROM drive.

The seventh generation of SCSI I/O technology, Ultra320 features an increased speed at 320MB per second, paced data transfer, running clock, training patterns at the start of a transfer series, skew adjustment, and either driver pre-compensation or receiver adjustable active filter (AAF). Devices using this technology support packetized protocol and often can support quick arbitration and selection (QAS).

Sending bundled commands, messages, and status bytes at full speeds is what the packetized version of this technology does best, which takes down the protocol overhead. The simultaneous transfer of many commands from multiple I/O processes in a single transaction is another great benefit of packetization.
