SUMMARY

IT professional, Unix/Linux IT System Administrator and desktop support

with extensive experience in the engineering, administration and support of

information systems. In-depth experience in the implementation, analysis,

PROFESSIONAL EXPERIENCE

Sun Microsystems, Menlo Park and Santa Clara,CA Datacenter. 1999-

2010

ILM (Infrastructure Lab Management). First 2 years was contractor to same

team and became full time employee. ILM is global team of 20 members in

Menlo Park, Santa Clara, Prague and St. Pertersburg.

I was Menlo Park team lead, we had five labs in Menlo Park with around 500

servers and a datacenter in Santa Clara with around 900 servers. We have

worked 80% production and 20% project a week. Production work is our

normal every day duties maintaining and repair hardware, OS, application,

backup and network support of around 1,400 servers. During the project

day, we can work on project to improve infrastructure, improve JET install

for Solaris, Linux, develop and improve inventory, Perl/Shell tools

development, Work on monitoring tools such as Nagios, Zenoss, OCS Inventory

tool, lab migration, move from IPV4 to IPV6 and many other projects. The

OS of servers are about 50% Solaris and 45% Linux of all versions and

platforms, (Sparc, AMD64, Intel 64bit, X86), all OS (Solaris, Linux,

Windows and Mac OS) servers in lab environment. Our team have also

provided office desktop support of about 100 software engineer's Menlo

Park office systems. I have also provided desktop and laptop support

mostly Windows OS with VPN issues, VNC, printing, NFS, virus, desktop

firewall, Samba and network conductivity.

I have created my own inventory system I named CIS "Cubit Inventory System"

on Ubuntu server (MYSQL/PHP/NMAP/HTML). It had capabilities to scan the

network and get system information using NMAP script and automatically

update the MYSQL database with PHP script. CIS tools can keep track of all

our team global team maintained servers which are over 5000 servers.

I have setup our first Nagios servers back in 2003 and upgraded to Nagios 3

few years back, I have also setup Zenoss Monitoring server and OCS

Inventory server running CentOS 5.3 OS on Xen hypervisor.

I have created various shell, perl, PHP scripts such as shut down script

for planned power outage. The shutdown script will shutdown all 5000

servers in less than one hour. Created perl script to parse twiki host

informations from twiki web and export to my Cubit inventory system.

Postinstall scripts for Linux and Solaris to configure various settings

such as setting up domain, NFS share, setmap, local user account and

installing OCS agent.

Knowledge of virtualization, Solaris zones on ZFS file system, virtualbox,

vmware player and Xen hypervior.

Supported 100 software engineers in Solaris compilers developer teams,

optimizers and debugger, HPC (High Performance Computing) software

developer tool team, Netbeans QA team, IDE and installer team. Sustain and

Release Engineering team, C/C++ compiler team, X86 Performance team and

Community Developers team.

Supported these teams with OS installation, NFS, Samba, Apache, Symantec

Anti-Virus and Desktop Firewall, Vmware Player, Virtual Box, TCP/IP, FTP,

Telnet, NIS, DHCP, VNC, attached storage, hardware, software, peripherals,

inventory database, Nagios/Zenoss monitoring and Network.

Supported OS includes Solaris 2.5. to 11 on Sun Sparc, 32bit x86 and 64bit

AMD and Intel platforms. Opensolaris on Sun Sparc, 64bit AMD and Intel

platforms. SuSE Linux SLES 8 to 11, OpenSuSE 10 and 11, Redhat Linux 6 to

9, RHEL 2 to 5, Fedora Linux 6 to 11, CentOS 4 and 5 and Ubuntu Linux 6.04

to 9.04, Windows NT, 2000, 2003 Server, XP, Vista, 2008 Server, Windows 7

and Mac OS 9 and X.

Monitoring and Inventory Application

OCS Inventory Tool: (Open Computer and Software Inventory Next Generation)

Deployment of OCS tool in our labs to help us keep track of the computers

configuration and software installed on all our 5000+ servers. My task to

to install OCS agent on all 5000+ servers and I have developed trusted

login between our main server and all 5000+ servers and created shell

script to install OCS agent and export critical information such as OS

type, versions, system status and update the Cubit Inventory Tool database

which I have created. Here is the scree

Nagios/Zenoss Monitoring Tool:

Nagios/Zenoss monitoring tool provides us with everything we need to

establish and maintain full operational awareness of our entire IT

infrastructure.

Nagios/Zenoss monitoring tool can monitor network, physical servers,

virtual servers and applications.

Nagios/Zenoss servers have features it can discover and configuration

tracking, availability and performance monitoring, fault and event

management and report analysis.

TRAINING CLASSES

Shell Programming for System Administrators:

Completed shell programming class and learned shell conditional logic, user

interaction, loops, menus, traps, and functions. Implemented gained shell

programming knowledge to create shell scripts.

Created shell scripts to setup ssh trusted login of more than 2,000 servers

and run weekly cron job to get critical informations such as system status,

OS version change, system activity and system log.

Solaris 10 ZFS Administration:

Completed Solaris ZFS class which offers advance in data management, better

data integrity, performance improvement, volume management capabilities

using storage pools, ZFS snapshots and clones with Zones and

troubleshooting and recovering data.

Sun StorEdge 3310 SCSI and 3510 FC Arrays:

Completed Sun StorEdge class and learned how to successfully install,

administer, and maintain the Sun StorEdge 3300 series and Sun StorEdge 3500

series storage arrays.

Perl Script Programing:

Completed Perl programming language class, focusing on hands-on labs.

Created Perl script to gain access to Cubit Inventory database and

manipulation the data, modular programming, CGI programming, debugging &

advanced pattern matching and reporting.
