Beyond exam success, the program is structured to impart foundational yet advanced knowledge, fostering a holistic understanding of data center virtualization principles.
Engage with a blend of expert-led instruction, detailed theoretical discussions, and immersive hands-on labs that reinforce every crucial concept.
Requirements / Prerequisites
A foundational understanding of general IT concepts is highly recommended, including basic networking principles (IP addressing, subnets) and familiarity with server hardware components.
Participants should possess working knowledge of a modern operating system (e.g., Microsoft Windows Server or a popular Linux distribution) for basic system administration tasks.
An eagerness to engage actively with the practical, hands-on lab environment and a proactive approach to troubleshooting will significantly enhance the learning experience.
While not strictly mandatory, preliminary conceptual knowledge of shared storage technologies (e.g., NAS, SAN, iSCSI) will aid in grasping advanced storage virtualization topics more rapidly.
Basic familiarity with command-line interfaces can be beneficial, particularly when working with ESXi hosts or performing specific administrative functions.
Skills Covered / Tools Used
vSphere Infrastructure Deployment: Master the installation and initial configuration of ESXi hosts and the deployment of vCenter Server for centralized management.
Virtual Machine Lifecycle Management: Learn to create, configure, clone, and template virtual machines. Administer virtual hardware, manage snapshots, and understand guest OS installation.
vSphere Networking Configuration: Implement and administer vSphere Standard Switches (vSS), including VMkernel adapters, virtual machine port groups, and network teaming for redundancy and performance.
vSphere Storage Provisioning: Explore various storage types (e.g., VMFS, NFS, iSCSI). Learn to provision and manage datastores, configure host access, and understand storage best practices.
Resource Management & Optimization: Configure Resource Pools to allocate CPU, memory, and network resources. Implement vMotion and Storage vMotion for dynamic workload migration without downtime.
High Availability & Disaster Recovery: Deploy and manage vSphere High Availability (HA) for automatic VM restart and Distributed Resource Scheduler (DRS) for automated load balancing across hosts.
Monitoring & Troubleshooting: Utilize vSphere Client tools to monitor performance metrics, analyze logs, set alarms, and effectively troubleshoot common issues within the virtual environment.
Security & Access Control: Implement robust security by managing user roles, permissions, and integrating with identity sources. Understand vCenter Server security best practices.
Tools Used: Predominantly the vSphere Client (HTML5) for daily administration and management tasks. Hands-on labs provide access to a fully functional vSphere environment.
Develop an understanding of how to interpret performance charts and data to proactively identify and resolve bottlenecks in a virtualized data center.
Benefits / Outcomes
