Hardware service, maintenance, and repair. I spend the majority of my days working on IBM midrange and enterprise systems. I work on practically any type of system you could find in a data center but specialize in the former mentioned product lines. x86, SAN, NAS, and SAS are a breeze. I sometimes get caught up spending a lot of time working through critical problems in enterprise tape libraries (IBM, Quantum, Quantum rebrands) as well.
Apologies to the community in advance for my horrible coding questions. Programming and scripting was never my strong suite as much as I appreciate the helpfulness of having those skills.
