3.2 SCSI LVD-to-HVD Converter
HP has recently certified an LVD-to-HVD converter to allow customers to use HVD disks with the
newer LVD HBAs. The HP Hardware Provider (HPHP) program has successfully certified Rancho
Technology’s LVD-to-HVD converter products on 11i v2 servers. This product meets the HP
Hardware compliance testing criteria and is now officially “Certified for HP-UX”. This will
enable customers who wish to continue using their legacy HVD devices on 11i v2 servers

Product Description:
The LVD-to-HVD converter is connected between an LVD HBA port and an HVD peripheral
device to allow HVD devices to be used with LVD HBAs (the older HVD HBAs are not supported
on 11iv2). The converter comes in two product types:
• RTLVD-PHVD stand alone unit. A small single port converter that runs on 12 volts DC.
• RTLVD-HVDRxE 1 to 4-port enhanced rack mount unit. This is a 1U Rack mounted
QUAD SCSI multimode SCSI Converter with up to 4 SCSI ports.
The converter has been tested in single-initiator configurations with Ultra160 and Ultra320
cards only. Multi-initiator configurations are not supported.
