KEY PROJECTS
1. SIMULATION MODEL DEVELOPMENT of IBM Power Series Server hardware using SIMICS Simulator, spanning P5, P6 and P7 power processor series . SIMICS simulator is a full system simulator, used by the firmware, for code bring-up, in absence of actual systems. Various chips as part of the Server – including Server - IO Chips were simulated understanding respective Bit/Pin functionalities .
Full system (model) configuration was done using, python. TCP/IP networking standards have been followed keeping Linux Operating system technology.
Following Hardware parts were designed as part of SIMICS engine, modeled using C and DML and integrated to full system.
-Host Channel Adapter -HCA – a channel adapter which stands as an interface between an end-node and a link in an InfiniBand subnet.
-Host Ethernet Adapter -HEA model was done keeping HCA as backbone, to fit in to an IO chip (P5IOC2) .
-PCI-X Host Bridge - PCI switch that connects multiple PCI devices to one slot in a system.
- Memory Management Unit (MMU) of IBM server IO chip - MMU provides address translation capability for different units in IO chip.MMU simulated model supported 4K to 4G page sizes.
-Distributed Virtual Ethernet Bridge (P7 Power series), Layer 2 networking connectivity between IBM blade servers of data centre network and external networks. Followed TCP/IP Layer 2 standards.

2. HYPERVISOR-FIRMWARE VERIFICATION - IBM P series servers
Functional Test Case ( FTC Test Cycle )/ Integration Test Case ( ITC Test Cycle ) for IBM P series servers.
Responsibilities:
-Identification of test cases for functional flow of different features of Power Hypervisor.
-Ensuring 95% coverage of entire server system with FTC/ITC Cycles
