The 3395U3 is the new generation 64-bit PCI to Ultra3 (Ultra160) Dual Channel SCSI high-speed host adapter. The 64-bit PCI bus can provide a maximum of 133*2=266 MB/Sec of bus signal for power user’s need. The dual SCSI channels provide 16-bit Low Voltage Differential (LVD) and Single-Ended (SE) SCSI solutions for your computer, using only one PCI slot. This interface can provide a maximum of 160 * 2 = 320 MB/Sec burst transfer rate, and 30 devices connected capabilities, which can meet the increasing requirement on today’s mass storage needs. The 3395U3 is able to downward compatible with legacy devices. The 32-bit PCI bus, legacy SE Fast/Ultra SCSI devices, narrow or wide, and the newest Ultra2 / Ultra3 SCSI devices, are all supported. These features make the adapter the best storage solution for next generation servers, RAID sub-systems, and workstations.

• Full 32-bit or 64-bit DMA bus master, zero wait-state PCI bus provide high-speed bus signal (133*2=266 MB/Sec max.); PCI specification revision 2.1 conformed.
  
• Two separate Ultra3 SCSI channels high-performance interface data transfer, support 30 devices (160*2=320 MB/Sec for 3395U3 burst transfer rate).
  
• Exclusive SureLINK™ domain validation technology verifies Ultra160 link integrity, ensures system operation at Ultra160 speeds, reduces system downtime, and identifies marginal cabling environments.
  
• Complete end-to-end protection of the SCSI I/O—Asynchronous Information Protection (AIP) safeguards all non-data phases and augments the cyclic redundancy check (CRC) feature of Ultra160 SCSI.
  
• Improved signaling and compatibility—Proven LVDlink™ signaling capability and SureLINK technology enhance system availability and manageability.
  
• 16-bit SE/LVD SCSI signal auto-detected, easy supporting for the legacy SCSI devices.
  
• Auto/Active SCSI bus termination, need no manual operation.
  
• Support both 32-bit and 64-bit PCI bus slot, easily adapted for all kinds of M/B.
  
• Single I/O Processor, true dual channel LSI53C1010-66Mhz chipset and the high-end technology design from LSI Logic/Symbios.
  
• Downward compatible with legacy SE Fast/Ultra SCSI devices, narrow or wide, and the newest Ultra2/Ultra3 SCSI devices
  
• One external 68-pin SE/LVD HD connector, two internal 68-pin SE/LVD connector, one internal 50-pin SE box header, provide maximum possible devices connection.
  
• Flash EEPROM BIOS, easy firmware code upgrading.
  
• NVRAM with easy operating BIOS configuration utility for board configuration information changing and storing.
  
• Storage Device Management System (SDMS) software from original design of LSI Logic/Symbios.
  
• SCSI activity LED for each channel.
  
• PCI board dimensions, approximately 6.85 x 3.8 inches.
  
• Universal 64-bit PCI card edge connector.
