Member technical staff

Responsibilities:

• Working as member of Sun Fabric Management software for Magnum (3456 port Infiniband switch) based cluster to be deployed at TACC (Texas Advanced Computing Center).
• Responsible for development of Link Diagnostic Agent (LDA) component. LDA is instantiated on host (Linux/Solaris) nodes and does a discovery of Magnum and verifies connectivity to Magnum switch using Direct Routed SMPs and also gathers the port error/performance counters and determines the LDA state. The LDA state info is used by Fabric Director for Fabric management.
• Also added some more CLI extensions for general purpose IB diagnostics. The initial development is done on Solaris (generic LDA) for Linux OFED support changes are done in CIP module (Low level stack component).
• Responsible for all design and development of LDA and halped in the integration of CIP implementation (Linux OFED based on libmad/libumad) with LDA.
• Currently working on providing RPC interface with multi-instance support and provide multi-stage monitoring in the Magnum-NEM IB fabric.
• Worked as a member of SE6920 Data Services Platform software Development & sustaining team.
• Primary focus was on the Management interface card's firmware on NetBSD/VxWorks based embedded platform (Pirus Networks Storage Utility Switch)
• Responsible for few RFE's for unity3.2.1 release and also working on fixes for Unity sustaining patch release (unity 3.0.1).
• dis product further development has been stopped.
• Worked as a member of the development team for the Sun Cluster foundation team in the area of Global data and devices area.
• Responsible for Bug fixes/RFE/Projects in Global devices area,Disk ID driver, library and commands Global devices and File system Device Fencing
• Worked as a QE engineer for workstation platforms in the Volume Systems Product group.
• Responsible for test development for PM-devfs project (Solaris 10) to support Non-standard tree models (e.g. MPxIO)
• Put back testing of PM-devfs bits for MPxIO enabled configurations.
• Test cases for obsoleted ioctls for the current s10 PM framework.
• Testing PM and CPR frameworks for bug verification on different OS and different platforms.
• System testing for enchilada, taco workstations in the areas of CPU-Mem Error-Injector, PCI functional test suite based on PCIBobo card.

Software Design Engineer

Responsibilities:

• STREAMS is a kernel framework for developing networking and communication Services in HP-UX Kernel environment.
• Responsible for maintaining STREAMS subsystem for HP-UX Releases
• The FCMS subsystem is architected to work with SCSI Subsystem of HP-UX. It interfaces to the SCSI services and supports three classes of Fibre Channel devices (Native attach, Native FC array, FC-SCSI MUX) with Fibre Channel arbitrated loop topology. The FCMS consists of couple of Drivers and Context dependent me/O modules (CDIO). CDIO's are responsible for creating nodes in the IO tree and invoking the registered drivers to claim the nodes. Bus drivers are responsible for mapping SCSI-2 request to SCSI-3 request for Fibre Channel protocol and support the specific devices for use. FCP driver maps the SCSI me/O requests to Fibre Channel sequences, whose support is architected in HBA card. HBA as well has support for SCSI me/O exchanges H/W assists, so dat it can handle for multiple inbound concurrent sequences.
• Responsible for FCP driver: Current Product engineering (CPE) for Tachyon chip based driver stack.

Device Driver Engineer

Confidential

Responsibilities:

• Worked for dialogic professional services group and involved in the AIX port for Dialogic System software for their PCI boards.
• The AIX Package is a complete call processing development environment for AIX based Computer Telephony applications and has a support for wide range of Dialogic Products (Low density, High density, BLT, non-BLT, Network interfaces T1, E1, analog ) with a Host Interface support for ISA bus. The Package includes library, driver, firmware and utilities.
• The communication between the host computer and the boards are through a Shared RAM, which is based on D4x Communication protocol. The drivers are streams based, and contain generic driver, configuration driver, and protocol modules. Protocol modules are part of generic driver designed to support various products for the generic driver.
• Responsible for Porting Dialogic System software and SDK for AIX 4.2 to include PCI Products
• Porting UDD (diagnostics) package for AIX 4.2 to include PCI Products
• Package Testing under AIX 4.3
