Project Details

Cisco Network Services Orchestrator (NSO)[Sep-2019 to till date]

Description:

NSO provides a robust bridge linking network automation and orchestration tools with the underlying physical and virtual infrastructure. It includes a rich set of northbound software interfaces and APIs that allow straightforward northbound integration. An extensible southbound device abstraction layer means NSO works with multiple vendors and multiple technology domains.Deliver high-quality services faster and more easily through network automation. Cisco Network Services Orchestrator (NSO) is industry-leading software for automating services across traditional and virtualized networks. Use NSO to add, change, and delete services without disrupting overall service, and help ensure that services are delivered in real time.

Dell EMC M&R-ViPR SRM (March -2014 to Aug-2019)

Description:

ViPR SRM is a software solution that provides multi-vendor capacity, performance, and configuration dashboards and reports for traditional and software-defined storage resources.

ViPR SRM provides detailed relationship and topology views from virtual or physical arrays as well as virtual storage technologies like VPLEX, IBM SVC, and ViPR Software-defined Storage. Performance trends across the data path help storage teams understand the impact traditional and software-defined storage has on applications.

Dashboards present capacity consumption and trends, identifying where and how capacity is utilized and when more will be required. Using ViPR SRM, administrators can continuously validate compliance with an organization's best practice rules and the EMC Support Matrix. Compliance reports helps ensure the environment is always configured to meet service level requirements. With this information easily obtainable, storage teams can truly optimize their storage environment to improve their ROI. ViPR SRM shows the reporting interface and some of the many features in ViPR SRM, including operational alerts, compliance reporting, and topology maps. The EMC M&R platform provides a common foundation for the EMC ViPR, ViPR SRM, and Service Assurance Suite products, providing a shared set of capabilities, functions, and user interfaces. The EMC M&R platform (formerly known as Watch4net) provides the core modules for an out-of-the-box monitoring and reporting solution that can be customized and scaled based on your environment and performance requirements.

Used DAO pattern to fetch data from database using Hibernate to carry out various database.

Used Hibernate Transaction Management, Hibernate Batch Transactions, and cache concepts.

Database development required creation of new tables, SQL Stored Procedures, Views, Indexes and Constraints, Triggers and required SQL tuning to reduce the response time in the application.

Dell EMC-ProSphere (June-2012 to Feb- 2014)

Description:

ProSphere has been designed to work with virtualized servers and in a cloud-style way, with storage delivered as a service. It supports federated storage and provides so-called end-to-end views, regardless of asset location, from servers to storage, with drill down.

ProSphere can be used by IT storage specialists to manage Symmetric, DMX, and VMAX arrays, including the VMAXe, plus VNX and Clarion arrays. It starts from a basis of having no agent, unlike Control Center, and is installed as a virtual appliance. When installed, it will discover the host data center VMAX infrastructure automatically. Generally this takes place in an hour but eight hours or more might be required for larger infrastructures. The product provides near real-time monitoring and analysis capabilities for the storage resources it manages. It supports "up to 1.2 million volumes, 36,000 ports and 18,000 hosts as part of a single logical domain." Any storage entity managed by ProSphere can be put in a group, a so-called Smart Group, and policies applied to group members. Typically objects sharing characteristics would be placed in Smart Groups.
