• Project 5: Working on Dell 14G Data Centre.
• The Dell Chassis Management Controller (CMC) is a systems management hardware (called as Server Enclosure) and software solution for managing multiple Dell blade server .
• It provides a secure web/browser-based.
• It is an interface/CLI/DMTF-based interface that enables an IT administrator to take inventory, perform configuration and monitoring tasks, remote power on/off blades, provide network connectivity, cooling, firmware update, and enable alerts for events on servers and components in the blade chassis.
• It is based on OPENBMC, C/C++11, Linux Kernel Configuration, I2C, PCIe, Nvme , Security protocol like Openssh , Openssl etc Code reviews, individual contributions for critical and deliverables, memory usage analysis and Debugging user application issues via Visual Studio and white box testing.CMC system management firmware on top of PowerPC 440Ex processor with Linux OS. It is based on Yocto , Linux kernel , Device drivers , Openssh and openssl , BSP(Board Support Package) , rootfs and initramsfs package .

• Project 6 - Kernel Porting from 3.18 to 4.9 on MSM8909 Qualcomm processor.
