ActiveScale Object Storage

By using erasure coding instead of multiple copies, ActiveScale Cold Storage reduces storage overhead and lowers costs by up to 80% compared to traditional multi-copy tape strategies.

2-dimensional erasure coding is Quantum’s patented technology that combines two layers of protection. The first dimension applies erasure coding across tapes to safeguard against multiple simultaneous failures, including entire tape libraries or even site-level outages. The second dimension applies erasure coding within each tape, so 99 out of 100 read errors can be corrected without mounting other tapes. This approach delivers up to 19 nines of durability with as little as 15-25% storage overhead, compared to 100-300% for multi-copy strategies, and allows objects to be read from a single tape for fast recovery.

ActiveScale is immutable-by-design. It provided S3 Object Locking, AES-256 encryption with unique keys per object, S3 IAM controls, MFA for admins, and an air-gapped cold tier for ultimate protection.

ActiveScale supports 2-site replication for disaster recovery, and 3-Geo configurations for maximum availability and strong consistency across sites.

Yes. ActiveScale scales from terabytes to exabytes without rebalancing, thanks to its patented Dynamic Data Placement technology and high-performance NVMe metadata.
