Q
What is SLR / MLR data tape?
A
SLR (Scalable Linear Recording) and MLR (Multi-Layer Recording) data tapes are magnetic tape formats designed for high-capacity, long-term data storage and backup.
Q
How does MLR differ from SLR data tape?
A
MLR uses multiple magnetic layers to increase capacity on a single tape, while SLR relies on a single recording layer for simpler, scalable storage.
Q
What storage capacities do SLR / MLR tapes support?
A
SLR tapes typically range from 800 GB to 4 TB (compressed), while MLR tapes can exceed 10 TB (compressed) per cartridge.
Q
What are the primary benefits of using SLR / MLR data tapes?
A
They offer high density, low cost per gigabyte, offline security, and proven reliability for long-term archival storage.
Q
Are SLR / MLR tapes compatible with existing tape libraries?
A
Most SLR / MLR drives support backward compatibility; verify your library’s firmware and drive generation for seamless integration.
Q
How reliable are SLR / MLR data tapes for long-term archiving?
A
Engineered for 30+ years of data retention, they feature error-correction and robust media coatings for consistent, reliable archiving.
Q
What is the typical lifespan of SLR / MLR data tape?
A
Under proper storage conditions (15–25 °C, 20–50% RH), SLR / MLR tapes last up to 30 years or more.
Q
How do I choose between SLR and MLR tape configurations?
A
Select SLR for straightforward scalability and proven reliability; choose MLR if you require maximum capacity per cartridge.
Q
Can SLR / MLR tapes be encrypted?
A
Yes, most SLR / MLR drives support hardware-based AES-256 encryption to secure data at rest and in transit.
Q
What data transfer speeds can I expect from SLR / MLR tapes?
A
SLR drives deliver up to 360 MB/s native, while MLR drives can exceed 500 MB/s native throughput, depending on model.
Q
How do SLR / MLR tapes compare to LTO technology?
A
SLR / MLR offer comparable reliability and long-term retention but may differ in capacity growth paths and ecosystem support versus LTO.
Q
What are the best practices for maintaining SLR / MLR data tapes?
A
Store in a controlled environment, run periodic integrity checks, clean drives regularly, and rotate tape inventories as recommended.
Q
Do SLR / MLR tapes support multi-layer recording?
A
SLR is single-layer by design, while MLR implements two or more magnetic layers to dramatically increase tape capacity.
Q
How do I label and track SLR / MLR data tapes effectively?
A
Use barcode or RFID labels, maintain a digital tape library database, and document cartridge usage and retention policies.
Q
What are the cost considerations for deploying SLR / MLR tapes?
A
Upfront costs include drives and cartridges; ongoing costs are minimal. Calculate total cost of ownership per TB versus alternative storage.
Q
How eco-friendly are SLR / MLR data tapes?
A
Tapes consume no power offline, have a low carbon footprint per TB, and are recyclable at end of life.
