EXPERIENCE

HP Array Configuration Utility - Network Storage: Confidential,USA.
Technical Analyst Nov 2011 - Till Date

The HP Array Configuration Utility is a tool used to configure network storage devices and servers.This tool interacts with driver modules of operating system through request and perform the operation on device. This request is used to send data, status and control command to device.The storage devices are configured,control and used through device driver request on device. The request can change the device status and can transfer data from/to device. This tool has different layers/stacks of codes to talk to user through device. These layers are devided into user application, middle layer for data structure and data base and, lower layer to communicate with devices through device driver code.Application layer responsible for user interface to interect with user. Middle layer is responsible for common data structure and data base for different kind of applications like command line interface and GUI interface etc. Lower layer is responsible to maintain device driver code for each kind of OS. This tool is used in all kind of operating systems and lower layer device driver code implemented for each operating systems.

The HP Array Configuration Utility (ACU) is a browser-based utility that can be used online (that is, while the operating system is running). It has different operating modes, enabling faster configuration or greater control over theconfiguration options. It suggests the optimum configuration for an unconfigured system and provides on-screen tips for individual steps of a configuration procedure. It enables online arraycapacity expansion, logical drive capacity extension, assignment of onlinespares, and RAID or stripe size migration.

Responsibilities:

• Designed, developed and Implemented algorithm for network servers to expand the capacity of existing tool with new released hardware.
• Designed, developed and Implemented configuration commands using SCSI and BMIC protocols for network storage devices and Servers.
• Designed, developed and Implemented for Logical configuration command to configure the device.
• Designed, developed and Implemented Identify command to identify the devices and hardware.
• Designed, developed and Implemented new windows driver to provide intermediate layer between drivers and applications.
• Designed, development and implement many new feature of New storage product.
• Worked on Performance Improvement & memory leakage tasks.
• Provided an optimal design solution for Client/Server transactions for device and applications.
• Provided support for production and development issues.
• Implement change requests: Object modeling, Coding and debugging, Unit testing, Update development documentation, High/Detailed design review, Code walkthrough/review, Review of Integration Test Plan and User documentation. Prepare and participate in the integration test meetings and technical meetings.

Environment: C, C++, Windows Device Driver and Linux Driver interaction programming. VC++ Integrated Development Environment and Debug Tools, Windbg, GNU gdb, SVN, MSVSS, Microsoft word and Microsoft excel. Windows XP/7, HP-Unix and UNIX/Linux.

Storage Smart Array Component Maintenance (Network Storage)- Confidential, USA
Module Lead July 2010 - Nov 2011

Storage Smart Componentis a network storage software to flash firmware onstorage drives. This software gives facilities to upgrade/downgrade firmware on storage devices based on requirement. This software interect with device driver layer of operating systems and perform requested operation. This software basically deal with inquiry command for discovering storage devices from storage device and give the discovered devices, and deal with firmware flashing command to flash firmware on discovered devices. This is developed for multiple OS and it provides separate device driver interaction layer for each operating systems.

Responsibilities

• Designed, developed and Implemented SCSI and BMIC command for storage devices like hard drive and controllers.
• Designed, developed and Implemented firmware flashing command for hard drive and controller using SCSI and BMIC specification and drivers.
• Designed, developed and Implemented device identify command for hard drives and controller using SCSI and BMIC protocol.
• Implementation work done for Windows, UNIX and HP-UX.
• Enhancement, bug analysis and bug fixing. Unix and UNIX/Linux.

Environment:C, C++, Linux Driver interaction programming. VC++ Integrated Development Environment and Debug Tools, Windbg, GNU gdb, SVN, MSVSS, Microsoft word and Microsoft excel. Windows XP/7, HP-Unix and UNIX/Linux.

MRI - Machine, Confidential, Japan :
Senior Software Engineer Oct 2009 - July 2010

• MRI is one of the safest imaging technologies available. By using magnetic fields and radio waves, MRI is able to provide your doctor with excellent images of your body without x-rays. Tools are developed for MRI machine which doctor or user can use to interact with MRI machine.
• This project involved development and design of MRI machine tools and user interface. MRI machine is use to scan any part of human body. To scan any part of human body, it requires set parameters and these parameters are set through tools. Developed tools to read data from MRI machine and send to user interface as well send data to machine from user interface. Engine is used to store data of MRI machine and connecting to application system.

Responsibilities

• Designed, developed and implemented tools for MRI machine to interact with users.
• Designed developed and implemented Reconstruction and Human diagnostic tools to human read data and get input from users and perform the related operations.
• Implementation work done for Windows, UNIX and HP-UX.
• Enhancement, bug analysis and bug fixing.

Array Software Engineering (Network Storage) - Confidential, USA
Senior Software Engineer March 2006 -Sept.2009

• Worked in design, development and maintenance of Clarion CX-Series and AX-Series of product of leading storage vendor EMC Corp. USA. Storage device consist of many drivers and supporting code to operate storage hardware and software. The base code/module for the storage device is Flare Driver and that consists various modules and sub modules such as CM, EM, Cache, Raid group, XOR, Rebuild, verify and expansion process etc that interacts with other components such as SCSI front end and Miniport driver. I was part of environment monitor (EM) module/team and EM module/team gives control and interface to hardware (e.g. Disk drives, Power Supply, FAN, Enclosure and LCC etc.) and provides driver for each components.

Responsibilities

• Designed and developed device driver code for clarion CX series product of EMC. Storage device mainly consists of Disk drive, LCC (Link Control Card), Power supply, FAN and enclosures. For which, needs device driver code to control the behavior of devices.
• EM module observes/controls the behavior of storage devices during run time. If any changes happened in any device(s), device will report to EM module and behavior of device is read by EM module. Storage device(s) is/are controlled by EM module by issuing read/write/control command to device.
• EM is in middle of device and upper layer software. This gets request from application and send to device and get back reply from device with device status.
• Device code is developed and designed for all existing and upcoming product of storage.
• Design, re-design and development of code.
• Design and re-design algorithm to interact with hardware and software.
