Client: Brocade Communications Inc., San Jose, CA (Dec '03 – Jan '06)

Project: Fabric Manager Enhancements. (FM Enh)

Module: Repository Management

Position: Senior Software Engineer.

Description

Fabric Manager (FM) is a highly scalable, Java-based distributed application that manages multiple Brocade switches and fabrics. FM provides the essential functions for efficiently configuring, monitoring, managing and dynamically provisioning Brocade Storage Area Network (SAN) fabrics. FM has a Graphical User Interface for the management and display of detailed information about multiple Brocade SAN fabrics and switches.

FM modules, which I have contributed, are:

Performance Monitoring (PM)

Advanced Performance Monitoring (APM)

Alert Management

Firmware Download

Repository Management

Performance Monitoring (PM) and Advanced Performance Monitoring (APM):

The Performance Monitoring module helps in tracking the traffic flow between switches by monitoring the different types of ports in the switch. Advanced Performance Monitoring module helps to set monitors on the Initiator/Target (F-Port), which helps in performance tuning and resource optimization in the SAN. APM also helps to identify the congestion in SAN. These modules displays the data collected as performance graphs that can be filtered for specific ports and time period for detail monitoring. These modules have scheduler threads for data collection that helps in generating the performance graph over a period of time. This module also acts as a client to FMWebService and gathers the data from it.

Alert Management (AM):

Alert Management module is a common module accessed by many other modules. This module has a Message Consumer that receives message from a Topic in the Weblogic Messaging. It converts the message data in proper format and inserts the data in the database. Sends back another message to refresh GUI based on the data inserted.

Firmware Download and Repository Management:

The Brocade switches will have FabOS releases every 6 months/year. The repository management module helps to import the firmwares from the Brocade Site or locally in another machine. It also helps to maintain the repository in the built-in FTP server of FM or externally in a FTP server. The repository module helps the user to maintain their firmwares and helps to create firmware profile for every user. The firmwares downloaded will be a single zip/tar-ed file. The zip/tar-ed file will be unzip/tar-ed and stored in proper structure. The Firmware download module provides the GUI to perform the firmware downloads to the switches, using FTP/HTTP. The client connects to the FTP server, where the firmwares will be stored in the repository, and downloads the firmware from the ftp server to the switch.
