Senior Software Engineer
Aug 2013 — Present
Working on the Platform Environmental Monitoring (Envmon) module for the PSU and Modular Line Card Bring up, which is ensures that board is protected from any damage which can arise due to thermal/ power/ current/voltage issues. Envmon module gathers all the sensors, power and fan information from underlying driver, sets the appropriate threshold (critical, major and minor) and periodically monitors them to ensure they fall in expected range. As part of the NeXus OS(NXOS) Infrastructure team, I currently working on the Cisco Nexus (insieme) standalone datacenter switches \'Global interface manager infra component\', Generic Online Diagnostic (GOLD) PD component with Programmability features which provides the Cisco NX-OS for datacenter switches more open and programmable, by exposing switches via REST APIs and protocols lie NetConf, gRPC and YANG model. Generic Online Diagnostic (GOLD) and Health Monitoring feature continuously tests and verifies the software and hardware functionality of the system while it is online in a live network. It helps in trouble shooting for fault identification on failure. On Nexus Data center switches, i have worked on the Global Interface Manager component is a VDC(Virtual Device Context) aware global component that co-ordinates with the VDC manager and the Linecard Manager (LCM) to assign interfaces to the right VDC. It provides infrastructure level functionality for shared interfaces(which are interfaces shared between the ethernet and fibre channel over ethernet VDCs), breakout interfaces (high bandwidth interfaces which can be split into lower bandwidth interfaces) as well as management interfaces. Responsibilities include infrastructure design, software implementation in the C programming language and debugging/troubleshooting any issues found in the course of the software development cycle as well as in the released code.
