Optical Disc Archive PetaSite EX Solution

Scalable Archive Solution for Data Centers.

The Secure Way to Archive and Preserve Your Data

The amount of data which is produced and must be retained is growing at an unprecedented rate. These include many types of data such as medical, seismic research, sensor information, document images, movies and more. And these huge amounts of data must be retained for extended periods of time. PetaSite EX Solution can provide the best data archive solution using larger capacity Optical Disc Archive (ODA) Technology. The highly reliable and efficient WORM media is the best way to protect your data with safe, long term storage.

Benefits of Optical Disc Archive

High Capacity

Scale-up to 50PB* per library. Scale-out to Multi-Library, Multi-Cluster configuration for unlimited archive capacity.

*Actual capacity may vary based on customer infrastructure.  

Low Total Cost of Ownership

Cost competitive with HDD and Tape. Low energy and cooling requirements.

High Speed Transfer Rate

High-speed 8ch enterprise optical drive. 187.5MB/s average write performance*. 375MB/s read performance.* Write/Read up to 1PB/day per library.

*Optical Disc Archive Generation 3

Over 100+ Year Life

The ISO-based accelerated media life test proves 100 plus years of ODA media shelf life*.

* Optical Disc Archive Generation 2 and 3. By internal tests referring to the
ISO/IEC16963 method.


Durable and resilient in a wide range of environment conditions. No data loss due to EMP, X-Ray or
water submersion.


Don’t risk your business on failure prone hard drives. ODA protects your data with a 100 + year media lifespan.

Standard Interfaces

S3 for data Access and REST API for System Management.

Multi-generation Media Compatibility

Eliminates costly data migration cycles. Future-proof technology investment.

Scalable and Flexible

PetaSite EX solution provides a highly scalable solution with advanced data integrity for both Put and Get operations.

Erasure coding can be configured to provide a redundant data structure across 4 or 8 media. This technique enhances performance while protecting against media, drive and robotics failure.  Scale up within a single library starting from 4.7PB to 50PB*, or scale out with a cluster option to provide additional capacity.

*The usable capacity may be less than the maximum capacity.

Safe and Secure

Native Write Once, Read Many (WORM) drive and media Technology provide physical media and data security, to meet International regulatory compliance requirements along with ransomware protection. Advanced security features include:

  • Encryption
  • “On The Fly” Verification
  • Fixity Check

Scaleable high capacity data storage solutions

Approx. 4.76PB

Base System of Master Module. Start small and scale up.

Approx. 50PB

Single Library of maximum capacity.

Approx. 50PB x N

Scale Out Multiple Library. Single/Multiple Namespace.
