LTO tape library with 48 cartridge slots

This Lenovo L4U library fits a 4U rack space and holds up to 48 LTO cartridges. It ships with zero drives installed and supports up to four drives. The unit accepts LTO-4, LTO-5 and LTO-6 media. Power input ranges from 120 V to 230 V AC.

Who this suits and who should look elsewhere

Organisations needing high-density offline backup or archive storage in a standard rack will fit this library. Sites that require drives pre-installed or that need more than four drives must add them separately or choose a different platform. Environments that cannot accommodate a 4U rack-mount form factor should consider alternative solutions.

Specification that decides fit

The library provides 48 cartridge slots in a 4U rack-mount chassis with support for up to four LTO drives. This capacity and drive limit determine whether the unit matches your backup window and retention requirements.

Questions about this item

How many LTO drives can be added to the 61734UL library as backup needs grow?

The library supports up to four LTO drives, which can be installed in the available bays when capacity or throughput requirements increase.

Which component reaches its limit first during continuous multi-drive operation?

The 48 cartridge slots set the maximum media capacity; once all slots are filled the library cannot accept additional tapes until some are removed or exported.

What are the power input specifications for the rack-mounted unit running all day?

The unit accepts 120 V to 230 V AC input, allowing it to operate from standard data-centre PDUs without additional voltage conversion.
