Abaco Systems / VMIC VMIPMC-5790-000 PMC Dual-Channel Ultra160 SCSI Adapter

The Abaco Systems / VMIC VMIPMC-5790-000 is a PMC dual-channel Ultra160 SCSI adapter designed for high-performance data transfer in demanding computing environments. Leveraging the LSI SYM53C1010 PCI dual-channel Ultra160 SCSI controller, this adapter offers two independent external SCSI channels that support both Low-Voltage Differential (LVD) and single-ended SCSI operations. It connects directly to a 64-bit or 32-bit PCI bus, operating at either 66 MHz or 33 MHz, and functions as a single PCI DMA bus master. The VMIPMC-5790 is well-suited for applications in workstations, server systems, computer clustering, telecommunications, signal processing, and distributed computing due to its robust data handling capabilities and high bandwidth.
