Concurrent Technologies Debuts PMC Dual Channel Ultra320 SCSI Controller
Concurrent Technologies introduces its new PMC based dual channel Ultra320 SCSI controller, capable of SCSI synchronous data transfer rates of up to 320 Mbytes/s. The SC PMC/320 provides two independent Ultra320 SCSI channels by utilizing the LSI Logic(R) 53C1030 Ultra320 SCSI controller. For increased data protection the SC PMC/320 supports boot volume mirroring (RAID 1 and RAID 1E) and for increased performance it supports data striping (RAID 0). By supporting a wide range of operating systems, the SC PMC/320 is suitable for intensive data storage applications such as database server systems, distributed computing, digital rendering, video-on-demand or image/signal processing.
To offload the intensive management of the SCSI I/Os from the PMC host processor, the 53C1030 Ultra320 SCSI controller features LSI Logic Fusion-MPTTM (Message Passing Technology). Fusion-MPT requires only a thin OS device driver, manages up to 100,000 SCSI I/Os per second and provides I/O controller interrupt coalescing, which reduces the number of host processor context switches. To maximize PCI bus transfer performance, the SC PMC/320 PCI interface operates up to 64-bit/66MHz, offering up to 528 Mbytes/s zero wait state data bursts. To maximize reliable end-to-end SCSI I/O transfers, the controller features SureLINKTM domain validation and Cyclic Redundancy Check (CRC). To maximize SCSI drive compatibility, it provides integrated LVDlinkTM transceivers to support (using auto-sensing) either Low Voltage Differential (LVD) or single-ended (SE) SCSI buses automatically.
The SC PMC/320 can support (narrow and wide) Fast SCSI, Ultra SCSI, Ultra2 SCSI, wide Ultra160 and wide Ultra320 SCSI standards. Channel 0 is via front panel 68-way High Density SCSI connector and Channel 1 is via the rear I/O P4 PMC connector. The SC PMC/320 can be used with any board level product featuring a standard PMC host interface, including Concurrent Technologies' CompactPCI(R), VME or Multibus II based PMC host boards.
The SC PMC/320 is fitted with 512 Kbytes Flash EPROM, pre-programmed with the SCSI BIOS and on-board configuration utility. This allows, for example, the SC PMC/320 to be configured to boot the operating system via the SCSI interface.
For ease of integration, many of today's leading operating systems are supported including, Linux(R), Windows(R) 2000, Windows NT(R), Windows(R) XP, Windows(R) XP Embedded, VxWorks(R), UnixWare(R) and SolarisTM.
