Depending on the role’s complexity a minimum of three-five years’ experience is normally required for a system administrator.

However, some employers may require further training depending on the role and if it requires the system administrator to specialise in a specific area. Therefore certificates and proof of training may be required from certain vendors.
Common certifications asked for by employers are Cisco Certified Network Associate and Cisco Certified Network Professional. Depending on the technologies used within the organisation Sun Solaris certifications for instance may be required for administrating Solaris Servers.

The role requires the individual to work with several departments outside of IT, on a daily basis. Therefore they need to possess a high level of patience and professionalism when working with other employees who will have a varying range of computer competencies.
The system administrator’s role can be seen as the ‘puzzle solver’ of the company and this can be highly stressful, especially if you work in an industry such as finance which is very depend on its IT operations. They require excellent problem solving and multitasking skills, should be a constant learner and able to remain calm when dealing with a crisis.
