System Administrators – System Administration is one of the key
tasks in data centers. System administrators do many activities like hardware
maintenance, cabling, and other software tasks. They are essential for
effective running of the data center. Some of the tasks of system
administrators are user group maintenance, patching, rebooting, security scans,
disk and storage usage scans, performance monitoring, File transfer, high-level
administration, malware and firewall management etc. System administrators were
earlier doing manual tasks and use to lift servers and equipments.
With advent of automation most of the tasks are being
automated and tasks that a sys admin performs
repeatedly are being automated. Automation through scripting, specialized
software and system scheduling frees her time, saves you money and prevents
human error-related mistakes. As hardware and virtualization technology becomes more reliable, the need
for dedicated systems administrators for managing the operating system and
physical servers decreases. Managing applications and how they work, building
scalable web services, database farms, and searchable, indexed file servers are
a few of the skills that the new sys admin is going to need.
Some of the prominent
Certification Programs:
The Microsoft Certified Systems Administrator
(MCSA)
"Microsoft
Certified Systems Engineer" - The MCSE program began with Windows NT 3.1
and is today one of the most widely known Microsoft certification programs. It
is available for the Platforms viz., Windows NT 4.0, Windows 2000 Server and
Windows Server 2003. Microsoft
has, in effect, discontinued the MCSE certifications for future versions of
Windows, replacing the single Platform MCSE award with a plethora of other more
narrowly focused certifications.
The Microsoft
Certified Systems Administrator (MCSA) certification Program helps to validate
an individual's ability to manage and troubleshoot network environments based
on the Windows Server 2003 operating system. As an alternative to the electives
on the MCSA, electives like table, certifications or certification combination
may substitute as MCSA electives. For example, CompTIA A+ and Network+ together
or CompTIA A+ and Server+ together can be credited and substituted as an
elective through a Microsoft and CompTIA partnership agreement. An individual may
also substitute Security+ alone, which counts for the elective and one of two
exams for the "Security Specialization." Security+ counts for MCSA
2003 and MCSE 2003.
Red Hat
Certified System Administrator (RHCSA)
RHCSA is an entry-level certification that
focuses on actual competencies at system administration, including installation
and configuration of a Red Hat Linux system and attaching it to a live network
running network services. To achieve the RHCSA certification the student must
pass EX200, a half-day hands-on lab exam. The minimum passing score for
the exam is 210 out of 300 possible points (70%). There is no prerequisite for
the exam, but Red Hat recommends preparing for the exam by taking courses in
Red Hat System Administration (RH124 or RH135) if one does not have previous
experience. RHCSA was
launched in 2002 as Red Hat Certified Technician (RHCT).As of July 2009 there
were 30,000 RHCTs. In
November 2010 it was renamed to RHCSA.
