TEKRAM DC-390U2W PCI
The DC-390U2 Series controllers support the new Low Voltage Differential (LVD) SCSI standard for reduced bus noise_ improved performance and longer cable length. ASPI (Advanced SCSI Programming Interface) managers for the following operating systems are included: MS-DOS_ Windows 95/98/NT, SCO Unix, NetWare.
Model DC-390U2W can support SCSI-2, Ultra-Wide and Ultra2 devices. The Symbios 53C141 Isolation IC allows all devices to work at their full speed with no degradation of performance to the Ultra2 bus. DC-390U2W ships with Internal Ultra2, Ultra-Wide and SCSI-2 cables, as well as an Ultra2 Terminator and an Internal-to-External SCSI-2 adapter bracket.

Model DC-390U2B can accept Ultra-Wide and Ultra2 devices_ and ships with Internal Ultra2 and Ultra-Wide cables_ along with an Ultra2 Terminator. *Mixing Ultra2 and Ultra-Wide devices on the DC-390U2B will bring the SCSI bus down to 40MB/sec performance.

TEKRAM DC-922 SCSI U2W RAID PCI
Tekram Technology Model DC-922 PCI Dual Ultra-2 SCSI Hardware based RAID controller makes high-end RAID reliability and advanced features available at an entry-level price. The result is that businesses that rely on mid-range and entry-level servers can protect their critical data with a value-priced RAID solution based on advanced RAID features that deliver a combination of reliability, performance and manageability.

The controller features a dedicated I/O processor with a data flow architecture that enables the controller to support up to 132 Mbytes/sec. of data bandwidth. Because the DC-922 controller performs RAID calculations directly on the adapter, the server’s host CPU can be used solely for application processing.

SCSI Card 2930 Ultra Features and Benefits


Features and Benefits
Gain Ultra SCSI Speed
Harness the power of Ultra SCSI* and improve your productivity. SCSI moves information between your computer and peripherals much faster than with standard interfaces.

Save Time With Multitasking
With this SCSI Card, your computer can talk to several peripherals at once, performing multiple tasks simultaneously--a great time saver.

Achieve Broadest Compatibility
Adaptec SCSI Cards are tested with hundreds of computer systems and peripherals to ensure the widest possible support now, and in the future. Since peripheral manufacturers design to Adaptec products, you can count on broad compatibility.

Upgrade Your PC Quickly
SCSI makes it easy to add a peripheral to your system. Daisy-chain up to 7 internal or external peripherals to this SCSI Card and enjoy the same great performance. This SCSI Card is ideal for connecting SCSI CD-R_ DVD_ removable, or hard drives, and can be used to connect Fast and Ultra SCSI peripherals like scanners, tape, CD-ROM, and Zip drives.

Manage Peripherals With Adaptec EZ-SCSI Software
EZ-SCSI software takes you step-by-step through the installation process and provides a full suite of applications for maximizing your SCSI peripherals, playing CDs, backing up with tape, and scanning documents.

Trust Adaptec--The World's #1 Choice For SCSI Cards
Adaptec is the industry standard in SCSI Cards. And all Adaptec SCSI Cards are backed by a 5-year, limited warranty and full technical support for two years.
*SCSI stands for Small Computer System Interface and is pronounced |scuzzy|.
