XLS Configurations
“I need to expand my XLS library system”
“My raw storage needs are outpacing my access needs, I will add another MEM”
“I need to add more tape drives to increase my access capability, I will add another LRM”
1 LRM, 1 MEM
1 LRM, 2 MEMs
2 LRMs, 1 MEM = OR
32 drives, 1,550 slots
32 drives, 2,625 slots
64 drives, 2,025 slots
High storage density coupled with flexibility during growth
Less linear movement to access large volumes of cartridges, over 2,800 cartridges can be accessed with an average 21” X axis motion
“Low Speed” robotics motion profile is more reliable and requires less power and cooling
Cartridge access performance does not degrade when expanding
