Job Dutiesspecific Tasks Methodologies And Applications Of Knowledge

Job Duties specific tasks, methodologies, and applications of knowledge required from Bachelor’s/Master’s level professionals. The duties include monitoring and managing the performance of ESX/ESXi servers and virtual machines, managing servers across multiple hardware platforms in development and production environments, and handling a large VMware infrastructure with hundreds of virtual machines. Responsibilities also involve capacity planning, design, installation, and configuration of VMware, CentOS, Citrix PVS servers, along with managing VMware features such as VMotion, Storage VMotion, Cloning, and templates.

Additional tasks encompass configuring high availability and distributed resource scheduling (DRS), managing Cisco UCS and HP server hardware, consolidating hardware health monitoring, and reducing administrative efforts through central management solutions. The tools leveraged include VMware vSphere Client, Cisco UCS manager, HP and Dell server management tools, and various network security and analysis courses to ensure secure and optimized network configurations.

The role extends to managing virtual desktops using VMware Horizon View, creating and maintaining persistent and non-persistent desktops, building gold images, and deploying clones. This work ensures efficient and secure virtual desktop infrastructure (VDI) deployment aligned with organizational needs.

The responsibilities further extend to the decommissioning and commissioning of Windows Server environments and VDI instances, utilizing System Center Virtual Machine Manager (SCVMM) and PowerCLI scripting. Storage management involves creating LUNs, setting up datastore clusters, and ensuring compliance with security policies using scripting and role management.

Monitoring and managing the performance of VMware vRealize Operations (vR Ops) and vCenter Orchestrator (vRO), as well as providing operational support for SCCM environments, storage, and server infrastructure, are also critical duties. This involves planning patches, disaster recovery, and storage solutions such as EMC Unity and NetApp FAS8200, ensuring high IOPS and data redundancy.

Supporting web services involves managing SSL certificates, server security, and performance tuning of IIS servers, including handling TCP/IP, SSL/TLS, and packet analysis. Deployment of Windows Server images via SCCM, WDS, PXE boot, and related technologies are part of routine operations, requiring deep understanding of network security and deployment best practices.

Further duties comprise consolidating datacenter peripherals, migrating virtual machines between datacenters, managing Active Directory, and ensuring business continuity through disaster recovery planning. Troubleshooting for diverse teams, integrating automation solutions such as PowerShell scripting, and maintaining operational standards are integral to this role.

The comprehensive management and operational support of virtualized environments, server provisioning, network security, and disaster recovery constitute core competencies in modern IT infrastructure management. This paper explores the methodologies, applications, and knowledge bases relevant to these duties, emphasizing the technical skills, tools, and coursework necessary for professionals in this field.

Monitoring and managing ESXi servers and virtual machine performance require a combination of technical tools such as VMware vSphere, which offers capabilities for resource management, load balancing, and performance optimization. Effective management involves continuous monitoring, capacity planning, and proactive troubleshooting. The use of VMware vRealize Operations (vROps) provides insights into performance metrics, anomaly detection, and predictive analytics, enabling administrators to identify issues before they impact operations (Khawaja et al., 2019). This approach aligns with best practices for maintaining high availability and optimal resource utilization in enterprise environments.

In addition to VMware technologies, managing physical hardware such as Cisco UCS and HP servers requires familiarity with hardware management tools like Cisco UCS Manager and HP Onboard Administrator. These tools facilitate server configuration, health monitoring, and hardware troubleshooting. Hardware consolidation strategies, including reducing administrative efforts through centralized health monitoring systems, contribute significantly to operational efficiency, reducing downtime and maintenance costs (Ibrahim & Yilmaz, 2020).

The deployment of virtual desktops using VMware Horizon View involves creating gold images and managing desktop pools. The process ensures consistent, secure, and scalable virtual desktop environments for end-users. The recompose, rebalance, and snapshot procedures are crucial for maintaining desktop consistency, deploying updates, and restoring images swiftly in case of failures. Virtual Desktop Infrastructure (VDI) management requires understanding of both the technical setup and security considerations, particularly in securing remote connections via protocols like PCoIP and Blast Extreme (García & Salazar, 2021).

Server decommissioning and commissioning involve the creation and deletion of virtual machines, management of storage via LUNs, and clustering of datastores to ensure high availability. The use of PowerCLI scripts automates many of these processes, reducing manual effort and error rates (Liu, 2022). These automated workflows support compliance with security and operational policies, centralizing access controls through Active Directory role management, and ensuring proper segregation of duties within the IT environment.

Monitoring system performance and undertaking troubleshooting are fundamental to ensuring operational stability. VMware vROps and System Center Operations Manager (SCOM) facilitate these activities, providing dashboards, alerts, and reporting functionalities that help administrators respond promptly to issues (Zhao et al., 2018). In network security management, courses in network analysis and testing offer insights into firewall operation, VPN connectivity, and packet filtering, strengthening security posture and preventing breaches.

Data storage solutions such as EMC Unity and NetApp FAS8200 are integral to meeting performance and redundancy requirements. Storage management involves planning RAID configurations, performing firmware updates, and deploying storage protocols like CIFS and NFS. These practices are guided by security architecture principles and operational security coursework, ensuring data integrity and availability (Shrestha & Kafle, 2020).

Security management extends to SSL certificate deployment, server patching, and securing web services. Managing cryptography, PKI, and SSL/TLS protocols requires foundational knowledge from cryptography coursework to ensure secure external communications and compliance with industry standards (Zhou et al., 2019). Proper configuration of firewalls, VPNs, and access controls is essential to mitigate cyber threats and safeguard sensitive data.

Disaster recovery and business continuity planning are critical for minimizing downtime and data loss. Techniques include data replication, backup, and cross-site failover configurations. Technologies like Zerto and VMware Site Recovery Manager automate recovery workflows, reducing manual intervention and increasing resilience (Ahmed et al., 2021). These strategies rely heavily on understanding active directory management, access control, and networking, reinforced through specialized coursework.

In conclusion, supporting a complex virtualized and hybrid infrastructure requires a deep integration of technical knowledge, tools, and methodologies. Continuous learning via coursework in areas such as network security, operational security, application security, and cryptography is vital. Additionally, practical skills in scripting, automation, and hardware management underpin the successful execution of these duties, ensuring that organizations maintain high performance, security, and resilience in their IT environments.
