Adaptec SCSI Card 29160


By: Sander Sassen

All the Adaptec Ultra160 SCSI cards, except the 39160, use Adaptec's SpeedFlex technology. SpeedFlex ensures maximum performance while maintaining full backward compatibility with legacy equipment. The SCSI Card 29160 comes with three internal and one external connector. One internal connector is used with LVD/SE devices, such as Ultra160 and Ultra2 harddisks. There is also one for Wide SCSI devices and a 50-pin SCSI connector for use with, e.g. CDROMs and CDRWs.

Fig 1. Adaptec's 29160 SCSI card, notice the three internal and once external SCSI connector.

The external can be used with any SCSI device but is Ultra160 SCSI-capable. Without SpeedFlex technology, connecting any legacy single-ended SCSI device to the LVD bus would degrade the performance of the entire bus and all attached LVD devices. Furthermore, SpeedFlex gives the card the ability to use all connectors, internal and external, simulteanously.

64-bits PCI-connector

The SCSI Card 29160 comes equipped with a 64-bit PCI slot connector. When interfaced with a 64-bit PCI slot operating at either 33 or 66MHz bus speed, the combined maximum throughputs are 266 MB/s or 532 MB/s respectively. With a normal 32-bit PCI slot maximum throughput will be limited to 133 MB/s.
