SCSI PMC Backup 

The MDR uses the SCSI PMC module to provide connectivity to SCSI tape stations for 
backup purposes.  
 

SC-PMC/8X5 SCSI PMC Module 

The SC-PMC/8X5 (X is 2 or 7) is a SCSI Adapter as a PCI Mezzanine Card (PMC) with 
a direct interface to the 32-bit PCI local bus. The SC PMC/8X5 supports both SCSI-I 
and SCSI-II. A narrow or wide single-ended interface is provided with both 
asynchronous or synchronous operation. 
 

Current Model 

SC-PMC/875 

SCSI PMC Module from Concurrent Technologies. 

 

Features used on the MDR system 

The SC PMC/875 SCSI PMC Module has the following features:  

• 

High performance: 32-bit DMA bus transfers at 110 MiB/s. 

• 

SCSI-II  

• 

Ultra Wide single-ended interface 

• 

Asynchronous or synchronous operation 

• 

Active termination and signal negation 

• 

Utilizing NCR's 53C875 SCSI I/O 

• 

Synchronous SCSI data rates up to 40MiB/sec 

 

Supported tape drives 

The MDR has been tested successfully with the following tape drives: 

• 

Seagate Sidewinder 50 AIT-1/2 

• 

Quantum DLT 7000. 

 

SCSI Tape Format 

The MDR system can be used with a SCSI PMC module connected to a Wide SCSI tape 
drive. Using the MDR Shell (or API) functions, it is possible to copy data from the 
storage device to the tape drive and vice versa. 
A recording can be saved on one or several tapes according to the tape capacity and the 
recording size.
