Speedy SCSI controller adopts PMC format
A new PMC-based dual-channel Ultra320 SCSI controller is capable of SCSI synchronous data transfer rates up to 320Mbyte/s.
A new PMC-based dual-channel Ultra320 SCSI controller from Concurrent Technologies is capable of SCSI synchronous data transfer rates up to 320Mbyte/s The SC PMC/320 provides two independent Ultra320 SCSI channels by using the LSI Logic 53C1030 Ultra320 SCSI controller

CompactPCI storage mixes HDDs and CompactFlash
Enables the integration of SATA300 mass storage drives into a 3U CompactPCI system, where performance, functionality, power, space and cost are key elements.
More power to critical cPCI processing
Single-slot 6U CompactPCI processor board uses the latest high performance mobile dual core processor from the Intel embedded roadmap.
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-MPT (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 maximise PCI bus transfer performance, the SC PMC/320 PCI interface operates up to 64bit/66MHz, offering up to 528Mbyte/s zero wait state data bursts.
To maximise reliable end-to-end SCSI I/O transfers, the controller features SureLink domain validation and cyclic redundancy check (CRC).
To maximise SCSI drive compatibility, it provides integrated LVDlink transceivers to support (using autosensing) 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, VME or Multibus II based PMC host boards.
The SC PMC/320 is fitted with 512Kbyte Flash EPROM, preprogrammed with the SCSI BIOS and onboard 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, Windows 2000, Windows NT, Windows XP, Windows XP Embedded, VxWorks, UnixWare and Solaris.
