HVD to LVD Converters

HVD to LVD Converters

HVD (High Voltage Differential) adapters and LVD (Low Voltage Differential) devices are normally incompatible due to their

different signaling voltage levels. This incompatibility does not allow direct communication between the different

technologies. The HVD to LVD converter allows connectivity between legacy HVD Host Bus Adapters and today's LVD devices.

The converter provides:

Connectivity in direct attach or shared configurations of all currently available LVD devices, including disks, tapes,

libraries, and shelves (4314 or 4354) when used with the KZPBA-CB and 3X-KZPBA-CC HVD adapters. With the

retirement of StorageWorks 1 disks and HVD shelves (BA36R), converters are desirable where upgrades to LVD HBAs, or

upgrades to current operating system versions are not possible.

Shared and direct attach configurations are interconnected much the same as those previously configured with

homogeneous HVD solutions, except that the HVD output is now passed through the converter before proceeding to

the LVD device. Where required, Y cables (BN21W-0B), terminators (H879-AA), cables (BN38C-10, BN37A-20), one

or two HVD/LVD converters (one-port, two-port), Memory Channel adapters (CCMAB), one Memory Channel cable

(BN39B-10), are used in conjunction with the LVD device of choice.
