The ATTO ExpressPCI UL4S offers the latest in SCSI storage connectivity, delivering the
ultimate data-delivery performance of up to 320 MB/sec. The UL4S which features the new
PCI-X bus interface and incorporates improved SCSI standards, is ideal for delivering
data to the most demanding Enterprise server and high-end workstation environments.
Enabled with ATTO's exclusive VpathTM Technology, the UL4S offers users the flexibility
of connecting high-speed Ultra320 devices externally and slower legacy devices
internally, or vice versa, without sacrificing the performance of the high-speed device.
This allows users to take full advantage of Ultra320 and legacy speeds
simultaneously.
Product Details
- Ultra320 SCSI performance enables high throughput for servers and high-end
workstations - One external and one internal channel allow users to attach Ultra320
drives externally and slower legacy devices internally for aggregate throughput of up
to 320 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,
Domain Validation, Quick Arbitration Select, Packetization, Cyclical Redundancy Checks
