PROJECTS & PAPERS PRESENTED

a) Micro Controller Based Controller for Different Types of Motor’s

MARCH 2008

Project Description:

A Micro controller is a tiny, mostly self-contained computer. They are generally slow (~8Mhz) and have no monitor, no keyboard, little RAM, etc. Most micro controller have a number of digital inputs and outputs. The output of the micro-controller based stepper motor will be in step angle (e.g., 180 steps2=360). A micro controller based system that converts the commands coming from the personal computer in series format to the required digital format and which drives the stepper motor to the desired angle. This stepper motor is used for position control. It uses the AT890C2051 micro controller to receive the commands from the pc having graphical user interface for data entry. A MAX232CPE chip is used to convert the signals from PC’s COM port to RS232 levels for sending and receiving the data through the serial port. The 2051 micro controller is economical and sufficient for small application.

b) Next Generation Raid (Raid-6):

FEB 2009

Project Description:

RAID 6 is an extension of RAID 5.RAID 6 is designed for tolerating two simultaneous HDD failures by storing two sets of distributed parities. Apparently the complex mechanism is likely to compromise data rate in and out of the system. Raid 6 significantly enhances the reliability of the new Enhance RAID family even both are built upon low-cost high capacity SATA drives It stripes blocks of data and parity across an array of drives like RAID 5, except that it calculates two sets of parity information for each parcel of data. The goal is solely to improve fault tolerance. RAID 6 can handle the failure of any two drives in the array while other single RAID levels can handle at most one fault.

\

RAID 6 protects against multiple bad block failures while non-degraded. Intelligent RAID solutions utilize an input/output subsystem that is separate from the host CPU, to provide greater performance and reliability.

Common Name(s): RAID 6. Some companies use the term "RAID 6" to refer to proprietary extensions of RAID 5; these are not discussed here.

RAID 6 Advantages over RAID 5:

1. RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity)

2. Data is striped on a block level across a set of drives, just like in RAID 5, and a second set of parity is calculated and written across all the drives.

3. It provides for an extremely high data fault tolerance and can sustain multiple simultaneous drive failures

4. It protects against multiple bad block failures while non-degraded

5. It protects against a single bad block failure while operating in a degraded mode

6. It provides perfect solution for mission critical applications.
