NTT Com plans to double its data center capacity in Osaka, Japan.

NTT Communications Corporation (NTT Com), the ICT solutions and international communications business within the NTT Group, announced it will launch its Osaka 6 Data Center and Osaka 7 Data Center by the end of 2019, thereby expanding its data-supply capacity 2.2-fold. According to Kenichiro Iida, Senior Vice President, Head of Cloud Services, "In response to the strong demand for massive data from cloud-service providers and other hyper-scale customers in the greater Osaka area, despite having launched our Osaka 5 Data Center in 2016 we have decided to build two new datacenters to further satisfy customers' needs. Data demands among hyper-scale companies are already robust, but we foresee even more data needs for hybrid cloud services that combine colocation and multi-clouds."

The Osaka 6, located in a building that NTT West Corporation is constructing in downtown Osaka, will launch with 460m2 of server space and eventually expand to 1,370m2 and 400 racks. The Osaka 7, situated in a dedicated datacenter building in Ibaraki, Osaka Prefecture, will boast initial server space of 3,800m2 and eventually grow to 9,500m2 and 4,200 racks. Both facilities will connect directly to Osaka's Dojima area, a major interconnection point for ISPs and datacenter operators, and services will be available to cloud service providers, hyper-scale operators, and enterprises.

Osaka 6 in downtown Osaka will be conveniently accessible from multiple stations, with the nearest subway station just a two-minute walk away, while Osaka 7 in Ibaraki will offer reduced risk of disasters such as floods and earthquakes. Both datacenters will fully comply with NTT Com's globally unified Nexcenter family standards and will feature redundant electric power, air-conditioning, connections, and security. Users will benefit from high-capacity, high-quality network infrastructure, with IX, ISP, and multi-cloud connectivity enhanced by direct connections to other NTT Com datacenters in Osaka via 10 Gbps Nexcenter Connect Metro.

Both facilities will be equipped with seismic isolation structure to minimize impact from a potential Nankai megathrust earthquake. Electric power, network equipment, server rooms, and other key facilities in Osaka 6 will be located on the second floor or higher to enable uninterrupted operation if the first floor were flooded. Communication cables will enter buildings through large earthquake-resistant tunnels to prevent damage from earthquakes or excavation work. Osaka 7 will be located in an area where flooding is uncommon, with electric power secured by direct connection to an adjacent substation.

Osaka 7 will operate as a campus-style datacenter offering fast, reduced-cost customization to meet specific customer needs. Server rooms will adopt highly efficient cooling wall-type air-conditioning and accommodate ultra-high-heat servers consuming 20kW or more, such as GPU servers. The facility is expected to deploy advanced technologies including a high-voltage direct current (HVDC) system for improved reliability and approximately 20% lower power loss through reduced power consumption. Japan's colocation market was worth around 540 billion JPY in 2018, with the datacenter business growing steadily at around 7% per annum.
