Sun StorageTek SL8500 is powerful tape library which enables 24×7 availability with fully redundant and replaceable robotics. StorageTek SL8500 modular library system is Sun extreme machine in storage. No matter how big you are or fast you grow, it totally accommodates your offline tape needs for data backup, archiving, and protection. It’s modular and can expand to 448 tape drives and 70,0001 tape slots–just under 200 feet long. just go to here for detail features and specifications.

Sun StorageTek SL8500 is an enterprise-class robotic tape library. One library stores a maximum of 6.5 petabytes of storage spread over 10000 cartridges. It supports a maximum of 64 tape drives. It uses up to 8 indepentent robots in each library. Up to seven such libraries can be connected side-by-side and automatically pass tapes between each other, forming a complex capable of storing over 70 PB of data and mounting 448 tape drives. Each tape drive installed in the sl8500 library has an independent data path. The aggregate data rate for all drives is 193.2 TB/hr. (Wikipedia).
