HPE R1R75B MSL 1/8 Gen3 Tape Autoloader
Overview
The HPE R1R75B is a 1U tape autoloader built for organizations that need unattended, high-capacity backup without expanding their rack footprint. Eight cartridge slots and native LTO-9 support deliver up to 360 TB of compressed capacity in a chassis that fits a single rack unit — a practical answer for mid-size data centers, branch offices with dedicated server rooms, and managed service providers running overnight backup windows. Its multi-generation drive compatibility and dual SAS interface speeds also give infrastructure teams room to grow without forcing a platform replacement.
Key Features
- 360 TB Compressed Capacity (LTO-9, 2.5:1): With LTO-9 Ultrium 45000 cartridges and a 2.5:1 compression ratio, the R1R75B stores 360 TB in just eight slots — enough to consolidate backup rotations that previously required manual swaps or secondary media libraries.
- 300 MB/s Transfer Rate: At 300 MB/s native transfer, a full backup window that used to run overnight can finish in a fraction of the time. For environments with tight RPO requirements, that margin matters.
- LTO-9 / LTO-8 / LTO-7 Multi-Generation Support: Backward compatibility across three LTO generations (Ultrium 45000, 30750, and 15000) means existing tape media investments are not stranded at migration time. You can phase in LTO-9 cartridges while continuing to read legacy media.
- AES 256-bit Encryption: Hardware-level AES 256-bit encryption protects data at rest on every cartridge — a requirement for HIPAA, PCI-DSS, and similar compliance frameworks where encrypted offsite tape is an accepted backup tier.
- Flexible Host Interfaces — 8 Gb/s FC, 6 Gb/s SAS, 12 Gb/s SAS: Three interface options let you wire directly into Fibre Channel SANs, connect via legacy 6 Gb/s SAS HBAs, or push throughput headroom with 12 Gb/s SAS — without needing protocol converters or additional adapters in most standard server environments.
- Compact 1U Form Factor: A 1U chassis means the autoloader fits in dense rack configurations without displacing switching or compute gear. It is particularly practical in colocation environments where rack space is billed by the unit.
- 8-Slot Cartridge Magazine: Eight slots support fully unattended backup operations — load the magazine, schedule the job, and the autoloader handles media rotation without operator intervention until the next scheduled maintenance window.
Integration and Compatibility
The R1R75B connects to standard SAN fabrics over 8 Gb/s Fibre Channel or directly to server HBAs via 6 Gb/s or 12 Gb/s SAS. Most enterprise backup software platforms recognize LTO-9 autoloaders as SCSI medium changer devices, meaning integration with Veeam, Veritas NetBackup, Commvault, and similar solutions follows standard tape library provisioning procedures. Confirm HBA and driver compatibility with your specific backup software version before deployment.
Frequently Asked Questions
Q: What is the compressed storage capacity of the HPE R1R75B with LTO-9 tapes?
A: The R1R75B delivers 360 TB of compressed capacity when loaded with LTO-9 Ultrium 45000 cartridges at a 2.5:1 compression ratio across its 8 slots.
Q: Which tape generations does the MSL 1/8 Gen3 support?
A: It supports LTO-9 Ultrium 45000, LTO-8 Ultrium 30750, and LTO-7 Ultrium 15000, providing backward read/write compatibility across three generations.
Q: What host interface options are available on the R1R75B?
A: The autoloader supports 8 Gb/s Fibre Channel, 6 Gb/s SAS, and 12 Gb/s SAS host interfaces, covering both SAN-attached and direct-attach server configurations.
Q: Does the HPE R1R75B include data encryption?
A: Yes. The R1R75B includes AES 256-bit hardware encryption, securing data written to each tape cartridge at rest.
Q: What is the warranty on the HPE R1R75B?
A: HPE provides a 1-year manufacturer warranty on the R1R75B.
The R1R75B earns its place in mid-tier data center backup stacks primarily because of its 300 MB/s transfer rate combined with 8-slot capacity — that combination means you can run a full 360 TB compressed rotation unattended without saturating a 12 Gb/s SAS link or requiring a second unit to meet your backup window.
Technical Highlights:
- AES 256-bit Encryption: Hardware-enforced on every cartridge write — not a software layer that adds CPU overhead on the backup server. For regulated workloads (healthcare records, financial archives), this is a hard requirement, not a nice-to-have.
- Dual SAS Speed Options (6 Gb/s and 12 Gb/s): If you are connecting to older SAS HBAs, 6 Gb/s keeps compatibility. If your host supports 12 Gb/s, you can saturate the 300 MB/s drive throughput without the interface becoming a bottleneck.
- LTO-7 Backward Compatibility: Three generations of backward support means media from an LTO-7 deployment can be read back without maintaining a separate legacy drive — a real operational savings during data center consolidations.
Deployment Considerations:
- This unit ships without a drive installed (0-drive configuration) — you must purchase and install a compatible LTO-9, LTO-8, or LTO-7 drive separately before the autoloader is operational. Factor that into total cost and lead time.
- Fibre Channel deployments require an 8 Gb/s FC HBA and zoning configured in your SAN fabric before the autoloader is visible to the backup host — plan for that provisioning step, particularly in multi-tenant or shared SAN environments.
The R1R75B is well-suited for MSPs and enterprise IT teams running nightly full backups of VM clusters or database servers where an unattended 8-slot rotation eliminates manual media handling across the week without requiring a full tape library chassis.
