"freeze-ray" is designed and validated to meet specific,
large-scale data center and enterprise market needs.

Adoption of optical media enables storage of critical & valuable data safely
for a long period with data integrity.

It is an immutable and low-cost solution to meet cold data archive needs.

Procudt Outline

Storing large-volume data safely at low cost

  • Large capacity, scalability
  • ●Maximum storage capacity of 1.9 petabytes (PB) per standard 19-inch rack.
  • ●Scalable modular structure allows flexible system configuration.
  • High reliability
  • ●Contactless media ensures high reliability in repetitive data read/write operations and prevents data loss.
  • ●Resists the effects of humidity, temperature, light and age-related degradation.
  • ●WORM (Write Once Read Many) media physically prevents overwriting to guarantee data authenticity.
  • ●RAID technology safeguards stored data from unexpected problems.
  • Reduction of costs (TCO)
  • ●Optical discs with a lifetime of 100 years* reduce the cost of periodic data migration.
  • ●No need for constant power supply and air conditioning reduces electricity cost and CO2 emissions.
  • * The estimated lifetime based on acceleration tests that are being conducted by Panasonic. Note that it is not a guaranteed value.

Scalable modular structure, smart data management

Scalable structure

The minimum configuration includes one bottom module, one base module and one extension module (with writer unit). The base module can be mounted with 76 3.6-TB magazines for a total of 273.6 TB. When mounted with seven modules (maximum) per 19-inch rack, the system achieves a large storage capacity of 1.9 PB (with RAID 0) at low bit cost. Also, the total data transfer rate reaches 360 to 1080 MB/s*1 by adding 6 extension modules with writer units. This can be flexibly designed to meet the user's needs.

*1 Unit measurement value obtained by a Panasonic standard test. Actual writing speed varies depending on environmental conditions, such as the server.

Smart data management

When the dedicated software, Data Archiver Manager (optional), is used, freeze-ray can be easily connected to an existing IT system via LAN. Since multiple freeze-ray units and all magazines can be managed as one namespace, data can be accessed intuitively without having to know which magazine has the target files. The freeze-ray system supports Linux, so it is possible to construct an object storage system suitable for archiving a large volume of unstructured data.

Application Examples

Data centers

[ Issue ]
Increased data volume is causing a rapid rise in backup costs.

[ Solution ]
Separate data with low access frequency from the existing backup environment, and transfer it to the freeze-ray secondary storage system.

[ Result ]
Optimizes the operating costs of the entire storage system.

Research organizations

[ Issue ]
Experimental data must be collected, stored and shared on a daily basis. When the main storage has a problem, past data cannot be accessed.

[ Solution ]
Store all data in the large-capacity freeze-ray system. If the main storage malfunctions, switch the data providing source to the freeze-ray.

[ Result ]
Uninterrupted data sharing service. Achieve high-speed random access.

Video production/broadcasting

[ Issue ]
There is a need for reliable, long-term storage of digitally converted video assets with an online/cloud solution.

[ Solution ]
Migrate existing video and data tapes to freeze-ray synchronized with Media Asset Management and an online/cloud solution.

[ Result ]
Passes down valuable video assets to the next generation. Off-line shelf control magazines also possible.
