Intercontinental Data Center Coordination Field Trial Using Cold Data Storage
University, Scality Inc., and Fujitsu Limited today announced that the three
organizations are jointly executing a cold data storage-focused field trial of
intercontinental data center coordination, together with partners in Japan and
Europe. Based on a consortium for collaboration between academia and industry
established in April 2016, the field trial will be conducted from November 2016
through to December 2017, and carried out between the data centers in Osaka
University’s Cybermedia Center and the data centers owned by Paris-based
In this field trial, the partners will build and
test the effectiveness of a storage platform coordinated across remote
locations, which offers improvements in throughput(1), disaster resilience, and
lower costs by eliminating redundancy within individual data centers. This is
done by duplicating data that is not updated very often, known as “cold
data,” in data centers on each continent, and applying a data sharing
technology from Scality called conflict-free replicated data type (CRDT)(2),
which is used in distributed computing environments.
Currently, in order to coordinate data between
data centers, two methods are used: one in which coordination is done through
synchronous communications over short distances where data transfer delays are
small, and another is to make backups through asynchronous communication over
long distances. When using synchronous communication over short distances,
there is a high probability that multiple data centers might be simultaneously
affected by large-scale disasters. When asynchronous communication is used over
long distances, there are large delays in transmitting data between data
centers, so the only option was standby redundancy coordination for backups or
At the same time, against the backdrop of
changes such as the spread of technologies like AI and the IoT, data which is
generally not updated, called cold data, has taken up more than half of all
data, primarily in the form of image and video data, and there is an increasing
demand for ways to accumulate new data and share it between multiple locations.
In order to achieve data center coordination between multiple locations,
however, there have been issues in achieving data synchronization between data
centers, and in improving response speed when reading the data.
Summary of the Field Trial
1. Trial Period
November 2016 – December 2017
2. Field Trial Details
In this trial, the participants will develop the
“Geo Replication” system to realize the layering and data redundancy,
which had only been achieved between data centers in close proximity or within
a stand-alone data center, at long distances such as between continents. By
layering and storing not only continually updated “hot” data and
infrequently updated “warm” data, but also “cold” data,
which is seldom updated, across multiple types of storage devices, long-term
storage functionality, lowered costs, and increased responsiveness and overall
throughput can be achieved across the system as a whole.
The companies participating in this consortium
will advance the development of the Geo Replication system, and the field trial
will be carried out, aiming for commercialization, with partners in Europe,
using data that is actually in use in Osaka University’s data centers.

from April 2017 through December 2017, together with joint field trial partners
in Japan and Europe, they will perform a usage trial for specific applications,
with a variety of data types.

Statement by Toshinori Kishi, Director of the
Storage Division, AVC Networks Company, Panasonic Corporation
Panasonic Corporation is participating in the
Geo Replication consortium, which offers a new way of using the ETERNUS DA700,
a Panasonic OEM product for Fujitsu Limited, and is very pleased to see this
field trial move forward.
Looking at the global market, Panasonic’s data
archive system using optical discs has been used by the largest social network
company in the US, demonstrating that it is already becoming a realistic option
for companies and public sector institutions that need long-term data storage.
By adding a new way of using it for remote coordination among data centers, we
expect it will also become an option in new fields, such as academic research
and storage services.
Statement by Marc Shapiro, Ph.D., Senior
Researcher of the French Institute for Research in Computer Science and
I welcome this new proof-of-concept
announcement, which builds upon collaboration between academia and industry, in
France and Japan. The growing data needs of modern society carry the
fundamental challenge of scaling both in volume and geographically. CRDTs represent
a technology base for sharing data consistently across long distances in a way
that is both economical and understandable to users and developers. I trust
that this technology will contribute to the success of this PoC.
