HPE MSL3040 Tape Library with 20 LTO-9 Cartridges

The HPE P84147-B25 is a 3U tape library module shipped with twenty LTO-9 Ultrium data cartridges. It provides up to 45 TB of compressed capacity per cartridge at a 2.5:1 ratio. The system targets organisations that need high-density offline backup and long-term archive storage.

SAS 12 GB/s interface with AES 256-bit encryption

Each module supports up to three LTO-9 Fibre Channel drives connected via 12 GB/s SAS host interfaces. The library includes hardware-based AES 256-bit encryption for data at rest. The 3U form factor allows dense rack deployment without additional cooling infrastructure.

Sustained 300 MB/s throughput across 40 cartridge

Under continuous operation the library delivers a native transfer rate of 300 MB/s per drive. With 40 cartridge slots per module and a maximum of 48U total height, the system scales to meet growing archive demands. The configuration suits workflows that write or verify large sequential datasets over extended periods.

Questions about this item

How do I install the 20 LTO-9 cartridges into the MSL3040 library slots, and which step is often missed?

Load each cartridge into one of the 40 slots per module; the step often missed is running the inventory scan so the library registers all 20 tapes.

What maintenance will the LTO-9 drive need after extended use?

The drive requires periodic cleaning with an LTO cleaning cartridge; the library will prompt when the 300 MB/s transfer rate indicates a cleaning cycle is due.

What limit appears first during sustained backups at 300 MB/s on the 12 GB/s SAS link?

The native tape write speed of 300 MB/s is the first bottleneck; the 12 GB/s SAS interface has ample headroom and will not saturate first.
