About The Customer
Türk Telekom is a multiplay provider of mobile, internet, phone, and TV products and services and a leader in the Turkish market. With the vision of accelerating Turkey’s transformation into an information society, they serve over 17.1 million fixed-line, 14.6 million broadband, 2.9 million TV and 24.6 million mobile subscribers. Their goals are centered on digital transformation to enable the provision of agile cloud services to both internal and external customers. The company's infrastructure is key for business-critical systems that sit at the center of Türk Telekom’s digital architecture—including its core billing and charging applications and databases, its SAP applications, and its virtualization and cloud service platforms.
The Challenge
Türk Telekom, a leading telecommunications provider in Turkey, was faced with the challenge of modernizing its infrastructure to facilitate the delivery of agile cloud services for both internal and external customers. The company's goals were centered on digital transformation to enable the provision of agile cloud services. Getting the infrastructure right was key for business-critical systems that sit at the center of Türk Telekom’s digital architecture—including its core billing and charging applications and databases, its SAP applications, and its virtualization and cloud service platforms. The company's storage infrastructure included hardware from a variety of vendors, but when it decided to replace its legacy billing system with a more demanding new application, it was time to modernize the storage layer too.
The Solution
Türk Telekom chose long-term partner Hitachi Vantara for most of its critical storage environments. The company opted for Hitachi Virtual Storage Platform (VSP) 5200 and 5600 arrays to modernize its storage layer. The new VSP 5000 Series arrays enabled Türk Telekom to switch from hybrid disk to non-volatile memory express (NVMe) storage, dramatically improving performance and reducing data center space, power, and cooling requirements. Türk Telekom also started using Hitachi Ops Center Administrator, Analyzer, and Protector. This software simplifies and accelerates storage management tasks, provides user-friendly analytics, and ensures data protection. It provides a common point of control for all the company’s storage arrays, as well as API libraries that enable integration with third-party tools such as Grafana, Ansible, and Micro Focus Operations Bridge.
Operational Impact
  • Türk Telekom has successfully modernized its core billing system to meet future needs and support broader digital transformation across the business. The new architecture is also much more environmentally sustainable. The total footprint has reduced from 23 cabinets to 9, saving space in the data center and reducing power and cooling requirements by around 60%. Furthermore, Hitachi Ops Center makes it easier for Türk Telekom’s IT team to manage its storage landscape. Storage administrators can now complete tasks such as provisioning, data protection, bottleneck analysis and reporting with just a few mouse-clicks.
Quantitative Benefit
  • 5x improvement in application response times
  • 4x increase in data throughput
  • 30% reduction in total cost of ownership
