DESCRIPTION
The UL4D dual-channel Ultra320 adapter is the latest addition to the ATTO ExpressPCI family of high-performance SCSI host adapters for data-intensive environments. This latest generation adapter boasts data-transfer rates up to 640 MB/sec. and offers support for the advanced PCI-X bus. It is an ideal fit for Enterprise servers and high-end workstations running high volume, mission-critical applications such as messaging and databases. Features: - Ultra320 SCSI
- Up to 640 MB/sec data-transfer rates
- Dual independent SCSI channels
- 64-bit/133 MHz PCI-X with backward compatibility
- Exclusive ADS™ Technology
- Supports up to 30 SCSI bus IDs
- Up to 12 meter cable lengths
Today's computing applications continue to place incredible strain on the host PCI bus and storage subsystem. In an ongoing effort to bring new heights of performance and reliability to today's professional applications, ATTO is pleased to introduce the ATTO ExpressPCI UL4D with PCI-X ... alleviating PCI bus bottlenecks. Leveraging this latest in SCSI storage connectivity, the UL4D delivers up to 640 MB/sec. data throughput - making it twice as fast as currently available SCSI host adapters. The UL4D's blazing fast speed, plus the advantage of the new PCI-X bus interface and improvements in the SCSI standard, enable it to deliver the high bandwidth required in data-intensive environments. Benefits: - Ultra320 SCSI performance enables high throughput for servers and high-end workstations
- Two external channels for aggregate throughput of up to 640 MB/sec.
- Supports up to 30 SCSI bus IDs
- Supports Low Voltage Differential (LVD) for cabling up to 12.5 meters per bus
- Compatible with Single-ended SCSI devices, providing cable distances up to 3 meters
- Supports all five original requirements of Ultra3 SCSI:
- Double Transition Clocking

I do audio production professionally, and dabble in graphics and video. Animation:Master looked like a great entry level tool for that type of animation. You had a good price, decent credentials, and looked a lot like you knew what you were doing. Your service has been very good. I appreciate the availability of tracking information. If I continue to get better at the video and graphics end of production, I'm sure I'll be back, looking for more tools and toys. - Randy |
