CIO, MTS India
Within MTS, storage is an extremely important component of the IT infrastructure. This is so because apart from the enterprise data being generated on a regular basis within the day-to-day office environment, a large size of data is being churned out every day in the form of Call Data Records and the data usage records of the millions of MTS customers spread across the country.
Annually, approximately 700 terabytes of data is generated within MTS and this is distinct from the data that is stored on the network. Out of the total data generated annually, 80 percent of the data stream comes from the customers, while 20 percent is generated internally via intra-office communications.
Being in the telecom industry vertical, we need to store data for various purposes ranging from operational needs, analytics practices and regulatory requirements.
Within MTS, we use SSDs, which can deliver high IOPS (Input/Output Operations Per Second) to host apps that require instant gratification and quick turnaround-time, such as analytical databases, reporting and MIS, data mining apps, and customer-facing apps. The next level of storage is SAS, which stores data that is actively accessed by users for say a period of two months. Once data is more than two months old, the data goes into SATA drives, while six months to one year old data goes into tape storage. Data that is older than one year is generally moved into tape storage for archival purpose.
