The EGI Open Data platform

The Open Data Platform (ODP) is a solution allowing integration of various data repositories available in a distributed infrastructure, offering the capability to make data open, and link them to key open data catalogues following respective guidelines, such as the OpenAIRE open access infrastructure. The core enabling technology of ODP is Onedata34, a data management solution that allows a seamless and optimised access to data spread over a distributed infrastructure.

Onedata storage is composed of a global network of providers who provision their storage resources to users. Any data centre, or even a personal computer, can become Onedata provider by installing the Oneprovider service near the physical storage resources. Providers have full control over which users can use their storage resources and to what extent - in terms of data size and transfer limits. Thanks to its highly optimized architecture, it enables high throughput access to large-scale data through standardized interfaces based on POSIX and CDMI, hiding from the users the low level storage interfaces, and allows the seamless application execution in multi-provider environment. Users can integrate data stored in different Oneprovider services in personal catalogues, which offer a fast and transparent access, regardless the geographical location of the data.

Setup your Onedata deployment into the EGI Federated Cloud

This is a step-by-step guide to setup a simple Onedata deployment into the EGI Federated Cloud. For further information about Onedata, please refer to its online documentation.

The deployment described on this guide is made of:

This setup can be easily extended to include more providers.

The guide also includes instruction to access data managed by this OneData deployment from other virtual instances started in the EGI Federated Cloud.

Space Management

This section describes how to create a new space in your OneZone instance and support it with your OneProvider instance.


Storage: NFS

Token: token copied in OneZone

Support size: amount of storage you want to assign to this space (<= the size of the block storage you attached to the OneProvider instance)

Access your data from an instance running into the EGI FedCloud

This section described how you can access the data stored in your OneData installation from any other instance created within the EGI FedCloud through a POSIX interface.

wget -q -O - | bash

export PROVIDER_HOSTNAME=[IP-OneProvider]

For example:

mkdir /mnt/onedata
export MOUNT_POINT=/mnt/onedata
oneclient --authentication token $MOUNT_POINT --no-check-certificate
