CONTENTS ECG075.0997 ... EXECUTIVE SUMMARY Since its introduction in February, 1996, the Compaq DLT Tape Array (which uses Compaq 15/30 GB DLT drives) has been an industry leader in backup performance capabilities. The DLT Tape Array II, which uses 35/70 GB DLT drives, sets new standards in high-speed backup performance. Early in 1997, Compaq performed a series of tests to examine the performance of the Compaq 35/70 GB DLT drive and the DLT Tape Array II. The objective of these tests was to find the highest-performance configurations in a variety of backup scenarios on Compaq servers running Windows NT and Novell IntranetWare network operating systems. The Compaq DLT Tape Array II provides high-capacity, high-speed tape storage for use in local and remote backup strategies. It uses the Compaq 35/70 GB DLT drive, which is engineered for superior performance. This brief addresses the technical aspects of highperformance backups that can reach and exceed 165 gigabytes per hour (GB/hr) with off-theshelf Compaq hardware. GB/hr 180 160 140 120 100 80 60 40 20 0 Network Backup One 100TX Ethernet connection. Four concurrent backups from four clients to four tape drives (Test 9). Local Backup: Novell IntranetWare One backup to eight tape drives (Test 2). Local Backup: Windows NT Eight concurrent backups to eight tape drives (Test 5).
