Data Archiver LB-DH8 series

Japanese
A scalable optical disc library system that satisfies increasing demand for long-term data storage [Made-to-order product]
Highly-reliable, low running cost optical disc storage suitable for long-term data storage
Scalable module configuration to flexibly respond to user needs

The LB-DH8 Series Data Archiver is a scalable optical disc library system that supports ever-increasing demand for longer-term data storage in data center business. Panasonic has leveraged its optical disc drive, media, and advanced robotics technologies to develop a scalable module expansion configuration that can support an increase of data with high reliability that is necessary for long-term data storage.
The system consists of data archiver magazines which hold twelve optical discs. Each magazine can store 1.2 TB of data. The system has a base module (magazine writer unit) and expansion module (magazine loader) that can house up to 76 data archiver magazines respectively. A maximum of 91.2 TB can be stored in each module. The system consists of three types of modules: base module, bottom module (magazine carrier), and expansion module combined with magazine management software. By installing additional expansion modules on the 19-inch rack, a flexible system configuration can be created according to the data volume. Up to seven modules can be installed to realize high-volume optical disc storage of 638.4 TB max. per rack.
The Data Archiver uses RAID technology. Twelve drive units concurrently operate twelve optical discs housed in a data archiver magazine to provide high-speed data transfer up to 216 MB/s*1 and high reliability to protect data from unforeseen failures. Optical discs that have a data storage life of 100 years*2 are adopted to eliminate regular data migration. Standby power consumption is only 7 W*3, significantly lowering power consumption and reducing running cost of data centers.

Scalable module configuration to store ever-increasing data

High-capacity, high-reliability, and high-speed data transfer are achieved

Panasonic's newly-developed robotics technology has realized this module configuration. The magazine carrier installed in the bottom module quickly transfers data archiver magazines housed in each module to the writer unit. In the writer unit, twelve discs in a data archiver magazine are loaded to ensure smooth writing and reading of large volumes of data.
Moreover, RAID technology is used on the twelve optical disks to distribute and record data onto them. It achieves high-speed data transfer up to 216 MB/s*1 . The archiver supports RAID 5 and RAID 6 to enable the customer to select their required level of fault tolerance by adding parity to data. It increases availability and reliability to protect data on drives and discs from unforeseen failures. Optical discs that have a data storage life of 100 years*2 are adopted to eliminate regular data migration. Standby power consumption is only 7 W*3, significantly lowering power consumption and reducing running cost.

Scalable configuration allowing more flexible operation

The system offers minimum configuration of one bottom module and one base module. Therefore, the system can be introduced and operated by a minimum initial investment. The base module can house up to 76 data archiver magazines, each storing 1.2 TB of data for reading and writing. A maximum of 91.2 TB can be stored in each module. By adding an expansion module that can house 76 data archiver magazines as well, the storage can be expanded according to the amount of data to be stored. The EIA-compliant 19-inch rack holding seven modules provides high-capacity storage of 638.4 TB max. (when RAID 0 is applied) at low bit cost. For expansion modules, configuration with/without writer unit can be selected, enabling flexible system operation to satisfy each user's need.
The depth of the archiver is 927 mm (including protruding parts), allowing it to be installed in standard 1,000-mm racks at data centers. This facilitates its use in existing customer environments.

Module configuration

Minimum configuration: One bottom module and one base module
Adoptable at minimal initial investment cost. Up to 91.2 TB of data can be stored.
Maximum configuration 1: One bottom module, one base module, and six expansion modules (without writer unit)
Up to 638.4 TB of data can be stored. This is an optimum configuration, typically for data centers for the purpose of cold archive*3 storage at low bit cost.
Maximum configuration 2: One bottom module, one base module, and six expansion modules (with writer unit)
Up to 638.4 TB of data can be stored. Seven writer units in total enable simultaneous writing to and reading from multiple magazines to satisfy customers' demands for multi-access.

*3: Long-term storage of data rarely used but prohibited to be deleted for the purpose of making such data readily available online

Dedicated management software facilitates easy management

Data Archiver Manager (server OS: compatible with Windows)

The system can be easily connected to an existing IT system via LAN using Data Archiver Manager software* provided with Data Archiver Manager (server OS: compatible with Windows).
CIFS network protocol supports the NAS head function. Multiple Data Archiver units and all data archiver magazines can be managed as a single logical volume.

* Compatible with Windows Server 2008 R2

Configuration Example

Data Archiver Manager (Server OS: Compatible with Linux)

Panasonic has newly developed a data archiver manager supported under Linux that can handle large-scale systems by extending its object storage technology. Magazines are managed by controlling the input/output of files using REST*1 based API. A single name space function*2 enables management of large-scale archive data and configuration of scalable storage. The NAS head function is also enabled.

*1: Representational State Transfer, a method of giving a unique identifier (URI) to all resources (files) and accessing using HTTP
*2: A function for expressing data on the network with a unique URL. A system that is well suited for storage scalability of large-volume data

Configuration Example

* Proxy Node: A server with a role to allocate files to each storage node
* Storage Node: A server to save files in magazines. Data Archiver is connected to it.

* NAS head can be established on a virtual server as well.
* The configuration varies according to the customer's use conditions. The system can be established with one server in some use conditions.
* In the case of NAS connection, a configuration similar to that compatible with Windows is enabled.

Higher operability and easier maintenance

Replacement of magazines

Up to eight data archiver magazines are installed respectively in a detachable drawer allowing them to be taken from the front face of the base module and expansion module. This design enables users to replace magazines in each drawer easily.

Replacement of modules and units

Main components including the bottom module and writer unit can be replaced easily in a state where they are installed on the rack.

Reliable, low-cost optical disc media suitable for long-term data storage

Data archiver magazine

This magazine is a 1.2 TB media device for data archiver where twelve pieces of recordable Blu-ray Disc™ for archive are stored in a 20.8 mm (H) shell. It protects discs from dust, finger marks, and scratches. The maximum writing/reading speed of 216 MB/s (when RAID 0 is applied) is achieved by separately recording data on twelve discs. Moreover, RAID technology is used to increase reliability and protect important data from unforeseen failures.
A magazine has a built-in HF band RFID. Management using bar code labels* is supported.

* Supported 1D code: Code 39, 2D code: QR code (model 2)

Blu-ray Disc™

Optical discs are highly reliable data storage media with a long history. Recordable Blu-ray Disc™ for archive inherit their characteristics, providing even higher reliability, and achieving a data storage life of over 100 years*. Media storage does not require power so does not generate heat. The discs can be stored at room temperatures because they are highly resistant to temperature and humidity changes.

*The estimated lifetime based on acceleration tests conducted by Panasonic at a temperature of 30 °C and humidity of 70%. Note that it is not a guaranteed value.
