Services in KDDI's “dotsquare” Data Centers

     KDDI Corporation(KDDI), Hitachi netBusiness Ltd(HnB), and Hitachi, Ltd(Hitachi) are pleased to announce that they have agreed their partnership to provide their data storage services in KDDI's “dotsquare” data centers.
     HnB will install and manage its Storage Services Access Point that is consist of a group of world-class products such as the Hitachi's disk array sub-system “SANRISE2000 series,” which is compatible withhighly efficient and scalable Storage Area Network.
     The new service will allow KDDI to offer reliable and efficient data storage as part of its “dotsquare” data center service to customers such as application service providers, contents service providers and network service providers. The new service is scheduled to start in July.

     KDDI branded its data center business “dotsquare” last October, and it is at the heart of KDDI's Internet Protocol business development, deploying a wide range of services from basic co-location and hosting services, through to higher-level operation, application and solution services which offer higher added-value.
     “dotsquare” data centers are located in central Tokyo in areas such as Otemachi, Shinjuku and Odaiba, and there are a total 27 sites in 13 cities throughout Japan, with a combined floor area of about 20,000 square meters.
     By early 2002, KDDI plans to build a new large-scale site near Shibuya exclusively for data centers, increasing the total floor space to about 40,000 square meters, making it the biggest provider of data center services in Japan. The storage alliance with HnB and Hitachi is one of KDDI's strategies to further enhance its “dotsquare” services.

     The partnership between HnB, Hitachi and KDDI “dotsquare” is part of HnB and Hitachi's strategy to expand the business to actively provide storage services to Internet data centers. By partnering with major Internet data center operators, HnB aims to keep its position as Japan's No. 1 storage service provider.

Background to storage services
     The recent explosion in the amount of content such as music and movies that is broadcasted and distributed over the Internet has prompted changes in information systems towards those that are centered around content. Because of this, storage systems that store and manage content play a very important role. However, Internet content companies face numerous problems such as a need to deal with unexpected increases in storage capacity, or data back-up in case of emergency, or increasingly complex operations management, and more efficient use of installation capacity.
     Therefore there are increasing demands on data center operators from customers such as ASPs, CSPs and other Internet companies not only to provide them with space and transmission capacity as in the past, but also to provide highly reliable storage services to manage large quantities of content.
