Ultra320 SCSI Host Adapter  

 High-performance, 320 MBytes/s Host Bus Adapter, ideal for high-end workstations, servers, and power users. Features seamless backward compatibility with Asynchronous, Slow, Fast, Ultra, Wide Ultra, Ultra2 and Ultra3 devices.

The P79320 incorporates the LSI 53C1020 controller which provides many benefits including:

SureLINK™ is the control for Ultra320 SCSI Domain Validation manageability enhancements in the LSI 53C1020. This is the very latest SCSI interconnect management solution. It verifies that the system is capable of transferring data at Ultra320 speeds, allowing it to negotiate to lower speed and bus width if necessary.
LVDlink™ Technology Benefits:

The P79320 supports LVD, a signaling technology that increases reliability of SCSI data transfers over longer distances than are supported by Single-ended (SE) SCSI. The low power requirement of LVD allows the I/0 transceivers to be integrated directly onto the ASIC. LVDlink™ technology lowers the amplitude of noise reflections and allows higher transmission speeds. LVD provides a long-term migration path to even faster SCSI transfer rates without compromising signal integrity, cable length, or connectivity.
          TolerANT™ Technology Benefits:

TolerANT™ technology includes active negation on the SCSI drivers and input signal filtering on the SCSI receivers.
The benefits of TolerANT™ technology include increased noise immunity when the signal transitions to HIGH, better performance due to balanced duty cycles, and improved SCSI transfer rates.
Status LEDs for System Information
The Paralan Host Bus Adapter (HBA) includes three LEDs on the board to provide system information. The "Bus Activity" LED blinks with bus activity. This can often be used along with LEDs on drives or SCSI expanders to diagnose the location of a problem. This LED includes header pins that may be used to power a remote LED.

The HBA Terminator Status LED illuminates when the terminator on the HBA is enabled. This provides the user information on correct termination of the SCSI bus.

The HBA Board Status LED provides an indication of the status of the HBA. When the board is working correctly this LED blinks on/off on a 1 to 2 second cycle. If the board detects a problem this LED blinks a series of long and short pulses. If the LED does not blink at all, it has detected a major problem.

9 TO 5 COMPUTER: Global Value-Added Distribution of NEW, used and refurbished computer periphery by a family-owned and operated company since 1979- distributing internationally computer related peripherals on the new, used and refurbished levels. HP, Compaq, IBM, CISCO, 3COM, APPLE, SEAGATE, and other major branded products as well as a MAJOR focus on Mass Storage related drives, media, storage racks, tri-optic barcode labels, libraries, autoloaders, duplicators, jukeboxes, HBA's, JBOD, Raid, SAN, NAS and software solutions.

As our stock of NEW, used and refurbished storage equipment changes daily, be sure to use our online chat service to get "real time" pricing from a knowledgeable sales technician. We also offer the lowest priced storage media on the net. Contact us now for drive rental, repair, duplication, software solutions or professional consultation.

*Buying refurbished can be better than buying new because flaws have been found and fixed, once it is deemed to be complete and in good working order it is repackaged to be sold at a lower price as refurbished.
