Infrastructure Support – Storage Administration ATMECS – Content Team Challenges: Limited documentation Lots of redundant backups being performed Setting up of appliance on AWS Issues with deduplication ratios due to DB compressed backups NetApp capacity issues due to skewed loads Shared folder issues due to user error Solution Approach: Storage team advised the Customer about the Volume movement feature and implementing to the environment after Customer approval. We will start planning to migrate volumes where more high I/O operations and more Storage Utilization. Storage Team will start migrating the volumes to other nodes after validating space and CPU utilization. During Production volume migration, Volume move will initially migrate the source data to the destination storage and pass it under cutover phase. We start communicating with Customer for the data cutover during Scheduled downtime to the dedicated Storage. ATMECS Contribution: SQL Server database of a particular application was protected by livevault backup solution and it costs 1500$ monthly per TB. To reduce the cost effect, we implemented NetBackup backup protection for these servers. Since these servers are hosted on AWS cloud, we built NetBackup Master server with S3 bucket storage unit on AWS to achieve better performance with minimum cost effect. In future, we are looking to add more clients under this AWS master server, which application server are in AWS platform for better server management. Infrastructure Support Storage Administration

NOC Services ATMECS – Content Team Challenges: Effective Management of Major Incidents Reduce Resolution Time Solution Approach: By using the services of a NOC, one of the most revealing value propositions is the enterprise’s ability to incorporate finitely predictable budgets. The saving is accrued due to two reasons. First, saving in cost due to reduced in-house IT infrastructure management staff, and second, better SLA (Service Level Agreement) deliverables due to the nature of the contract that can be made. ATMECS Contribution: Server Analysis – Identified assets contributing to the most number of incidents and fixed the underlying issues to achieve significant reduction in incidents Root Cause Analysis – An extensive analysis is done on the root cause of the incidents to avoid reoccurrence Reporting and Measurement – Developed reports to give management deep insight into the issues and trends in the environment. It will also show areas where improvements can be made or indicate any positive or negative trends in performance Knowledge Base – A centralized source for all knowledge and documentation that is accessible to the entire team and continuously update it with experiences and lessons learned for future reference and improvements.
