RAID & Storage Configuration

•    Configure RAID levels (0, 1, 5, 6, 10) via hardware and software RAID controllers based on redundancy/performance requirements.

•    Monitor disk health, rebuild arrays, and manage storage provisioning on enterprise storage systems (SAN/NAS — e.g. Dell EMC, NetApp, HPE, Hitachi).

•    Manage LUN allocation, zoning, and multipathing for SAN-connected hosts.

Virtualization / Hypervisor

•    Deploy and manage VMware vSphere/ESXi and Microsoft Hyper-V environments.

•    Perform VM provisioning, resource allocation, snapshots, migration (vMotion), and cluster/HA configuration.

Backup & Recovery

•    Design and manage backup jobs and retention policies using enterprise backup solutions (e.g. Veeam, Commvault, Veritas NetBackup).

•    Perform regular restore testing and maintain disaster recovery documentation and procedures.

Security & Hardening

•    Apply OS and application hardening standards (e.g. CIS Benchmarks) across Windows and Linux servers.

•    Manage patch compliance, endpoint protection/EDR, and vulnerability remediation.

•    Maintain access controls, privileged account management, and audit logging.

System Tools & Monitoring

•    Administer IT management tools such as ManageEngine ADSSP/ADManager Plus (self-service password reset, AD delegation), monitoring platforms, and ticketing systems.

•    Set up alerting and capacity/performance monitoring for servers, storage, and hypervisor hosts.

Documentation & Support

•    Maintain accurate infrastructure documentation, configuration records, and SOPs.

•    Provide 2nd/3rd-level support, incident resolution, and participate in change management processes.
