Features of mediaCONNECT


One of the Largest Internet Exchange (IX) Points in Western Japan

Offering a variety of IX and xSP access points, the urban network data centers (DCs) provided by NTT SmartConnect make up the heart of Internet connection services in the Kansai region.
The centers are connected by a network of optical fiber cables (Dojima Connect), providing connectivity to external services with the same degree of ease as on-premises connections, through service tunnels that secure a high level of reliability for data communication.

Case Studies with the Remote Hands

Customer G: A major overseas cloud service provider

Due to COVID-19, it was difficult to send employees to the data center to carry out installation work.
Customer G applied for the Remote Hands service through our web portal site (English site).
NTT SmartConnect maintenance staff wired fiber-optic patch cords between racks on behalf of the customer. To the customer’s delight, the work was completed quickly without the need to exchange a contract, and at a lower cost than an outsourced maintenance company.

Customer H: A major overseas telecommunications carrier

Upgrading Customer H’s server operating system required a large amount of on-site installation work.
Therefore, Customer H applied to NTT SmartConnect for help with this installation work.
At the data center, the NTT SmartConnect maintenance team installed the operating system on the customer's server, and carried out communications testing with the customer.
This would normally require a high level of expertise, and it would be difficult to bring the workers together at the same time; however, NTT SmartConnect enabled the speedy completion of all processes—from arrangement of workers to installation —while also reducing overseas travel and operation costs, leading to positive feedback from the customer.


Promoting energy efficiency at our data centers

NTT SmartConnect is promoting the introduction of energy-efficient equipment at our data centers and other facilities.
As well as the data centers already in operation, the Sonezaki Data Center, which opened in 2022, is equipped with various energy-saving facilities aimed at reducing environmental impacts.
In addition to this, we are working to improve power usage effectiveness (PUE) based on the NTT Group’s Energy Efficiency Guidelines.
