HPE AK379B MSL2024 24-Slot 2U Rack Tape Library
Overview
The HPE MSL2024, sold under part number AK379B, is a 2U rack-mountable tape library built for organizations that need a scalable, entry-level automated tape solution without committing to a fully populated system on day one. It ships with 24 cartridge slots and zero pre-installed drives — you choose which tape library drives to add based on your interface environment (SAS or Fibre Channel) and the LTO generation your workflow demands. That flexibility matters in mixed or evolving infrastructure where locking into a single drive type upfront is a risk.
At native capacity, the AK379B holds 240 TB across 24 LTO slots. With LTO-8 media and 2.5:1 compression factored in, that scales to 720 TB compressed — enough headroom for mid-market backup, archival, and disaster recovery workloads that have outgrown NAS-based retention strategies. Tape's 30-year rated media shelf life makes this a defensible long-term archive tier, particularly for regulated environments where data retention mandates run a decade or more.
Key Features
- 24 Cartridge Slots, 2U Footprint: Fitting 24 slots into 2U of rack space means you get meaningful slot density without sacrificing half a rack to tape infrastructure. For data centers where rack space is a real cost, this matters — you're not paying floor space for capacity that could consolidate elsewhere.
- 720 TB Compressed Capacity (LTO-8): Using LTO-8 cartridges at 2.5:1 compression, the MSL2024 reaches 720 TB in a single library. Even at native rates, 240 TB is a substantial archive tier for most mid-market environments. Pair this with LTO tape media correctly rated for your drive generation.
- 0-Drive Configuration: Shipping without a pre-installed drive keeps the entry price lower and lets you install exactly the LTO generation you need — LTO-8 for maximum current-gen density, or an older generation if you're integrating into an existing media pool. Drives install into the library's dedicated drive bays after purchase.
- SAS and Fibre Channel Interface Options: Whether your infrastructure runs direct-attached SAS or a Fibre Channel SAN fabric, the MSL2024 accommodates both. FC connectivity is the right call for multi-host environments where several servers need concurrent library access without dedicated HBA-per-host SAS cabling runs.
- Web-Based Remote Management: The built-in web interface lets administrators manage the library, check drive status, and monitor media inventory without dispatching someone to the data center. For organizations with remote or branch-office tape deployments, this eliminates the need for on-site IT staff to handle routine library operations.
- Removable Magazines with Barcode Reader Support: Standard barcode reader compatibility and removable magazines let you manage media in and out of the library systematically — critical for offsite vaulting workflows where cartridge tracking errors translate directly into recovery failures. This is not a convenience feature; it's a data integrity control.
- 30-Year Media Shelf Life: LTO tape's rated 30-year shelf life makes the MSL2024 a legitimate long-term archive platform, not just a backup rotation target. Organizations subject to FINRA, HIPAA, or government records retention mandates can commit to tape as their cold-tier without planning a media migration every five years.
- HPE StorageWorks Product Line: The AK379B belongs to HPE's StorageWorks family, which means drive upgrade kits (SAS and FC, across LTO-7 through LTO-9 generations) are available as discrete add-ons through standard supply channels — protecting the library investment as LTO generations advance.
Integration and Compatibility
The MSL2024 integrates into SAS direct-attach environments and Fibre Channel SANs. Drive upgrade kits for LTO-7 FC (N7P36A), LTO-8 FC (Q6Q67A), and LTO-9 SAS (R6Q75A) are available separately, giving you a clear upgrade path as capacity requirements grow or as newer LTO generations become the standard in your environment. The library's web-based management interface removes the need for proprietary management software for basic operations, though enterprise backup applications (such as those commonly used with HPE storage infrastructure) can integrate via standard device drivers. Barcode labeling support for cartridge tracking is compatible with standard LTO barcode label formats. Before specifying drives, confirm your host bus adapter (HBA) supports the chosen interface — SAS deployments require an 8644-compatible SAS HBA; FC deployments require a compatible FC HBA matched to your fabric speed.
Frequently Asked Questions
Q: Does the HPE AK379B ship with any tape drives installed?
A: No. The AK379B is a 0-drive configuration — it ships with 24 cartridge slots but no tape drives. You purchase and install drives separately using HPE StoreEver MSL drive upgrade kits matched to your required interface (SAS or Fibre Channel) and LTO generation.
Q: What is the maximum capacity of the AK379B?
A: With LTO-8 tape cartridges at 2.5:1 compression, the MSL2024 reaches 720 TB compressed capacity. Native (uncompressed) capacity across all 24 slots is 240 TB.
Q: What interface options does the AK379B support?
A: The MSL2024 supports both SAS and Fibre Channel interfaces, depending on which drive upgrade kit you install. SAS suits direct-attached single-host deployments; Fibre Channel is appropriate for multi-host SAN environments requiring shared library access.
Q: What is the warranty on the AK379B?
A: HPE provides a 1-year limited warranty on the AK379B MSL2024 tape library.
Q: How is the MSL2024 managed — does it require proprietary software?
A: The library includes a web-based remote management interface that handles routine operations — inventory checks, drive status monitoring, media management — without requiring proprietary software or on-site staff. Enterprise backup software integration is handled through standard device drivers.
Q: What rack space does the AK379B require?
A: The AK379B occupies 2U of rack space. Physical dimensions are 3.4 in H × 18.9 in W × 31.7 in D, standard for rack-mount deployment in a 19-inch rack enclosure.
The AK379B is a library chassis purchase, not a complete tape solution — and that distinction is worth being direct about before anyone configures a quote. What you're buying is the 24-slot MSL2024 enclosure with no drives pre-installed, which means your actual cost of ownership includes the drive upgrade kit (SAS or FC, your choice of LTO generation) on top of the chassis price. That said, for environments where you want the library now and want to defer the drive decision — or need to match an existing LTO-8 media pool — this is a clean way to get there.
Technical Highlights:
- 720 TB Compressed / 240 TB Native: At 24 slots with LTO-8 cartridges and 2.5:1 compression, you hit 720 TB in 2U. That's a meaningful archive density for mid-market shops that have exhausted their NAS retention budget and need a cost-effective cold tier.
- Dual Interface Support (SAS + FC): Drive upgrade kit selection drives your interface — pick SAS for straightforward direct-attach to a single backup server, or FC if you're sharing this library across multiple hosts in a SAN fabric. The library chassis itself doesn't constrain your choice.
- 30-Year Rated Media Shelf Life: This is the spec that justifies tape as an archive tier rather than just a backup rotation medium. For compliance-heavy environments with decade-long retention mandates, that shelf life is a real operational argument — it means you're not planning media refresh cycles every five years.
Deployment Considerations:
- The 0-drive configuration requires a separate drive upgrade kit order — plan for N7P36A (LTO-7 FC), Q6Q67A (LTO-8 FC), or R6Q75A (LTO-9 SAS) depending on your environment. Confirm HBA compatibility before ordering: SAS deployments need an 8644-compatible HBA; FC deployments need a fabric-matched FC HBA.
- Web-based management covers routine operations well, but if your backup application needs deep library integration (slot mapping, drive assignment, media pools), verify driver and software support for your specific backup platform before deployment — the AK379B's management interface is a complement to, not a replacement for, your backup software's device control.
The AK379B is the right chassis for a mid-market compliance or DR archive deployment where the team wants 2U tape automation, interface flexibility, and a clear LTO upgrade path — and is comfortable specifying drives as a separate line item.
