MagStor M3000E 40-Slot 3U Tape Library
3U Scalable LTO Library
Up to 25.6PB Native

The MagStor M3000E is a high-capacity 3U LTO tape library built for organizations that need scalable automated tape storage in a dense rackmount design. With 40 slots and support for up to 1 full-height or 3 half-height drives in the base chassis, the M3000E is well suited for enterprise backup, media archive, research data retention, compliance storage, and long-term disaster recovery workflows.
Scalable Capacity: From 1.6PB up to 25.6PB Native, Uncompressed Storage
The M3000E starts with 40 slots for up to 1.6PB native capacity using LTO-10 40TB cartridges. As storage needs grow, the platform can scale up to 640 slots and up to 16 full-height or 48 half-height drives for as much as 25.6PB of native, uncompressed LTO-10 capacity.
Expand as Your Archive Grows
Start with the 40-slot base chassis and add expansion modules as capacity, automation, and throughput requirements increase.
Base Library
40 slots
1.6PB native
Up to 1 FH / 3 HH drives
Expansion Modules
Add library expansion modules to grow cartridge slots and drive capacity as archive needs increase.
Power note: expansion power supplies are only needed when tape drives are installed in that expansion module.
Maximum Configuration
640 slots
25.6PB native
Up to 16 FH / 48 HH drives
The M3000E can be purchased as a 0-drive library chassis or configured with LTO SAS/FC drive bundle options, including higher-performance MAX drive configurations where available.
Why Choose the M3000E?
High-Capacity 3U Library Design
With 40 tape slots in the base chassis, the M3000E delivers significant automated media capacity while maintaining a compact rack footprint.
Scalable Drive Configuration
Support for up to 1 full-height or 3 half-height drives in the base chassis, and up to 16 full-height or 48 half-height drives in the maximum 640-slot configuration, gives teams room to increase throughput as backup and archive workloads expand.
Designed for Long-Term Data Retention
LTO tape is ideal for cold storage, compliance retention, ransomware-resilient offline copies, and cost-effective archive growth.
No Slot Licensing
All library slots are available without additional capacity licensing.
Software Compatibility: Check Your Configuration
Confirm support for the exact library, drive generation, host interface, operating system and application version before purchase. Library automation and LTFS support depend on the application and license; standalone-drive LTFS applications do not support library robotics.
