VCAP5-DCA Objective 2.4 : Administer vNetwork Distributed Switch Settings

Understand the use of command line tools to configure appropriate vDS settings on an ESXi host There is very limited commands for a Distributed vSwitch through the command line, as you can understand its a way to centralize your networking configuration and really I Continue reading VCAP5-DCA Objective 2.4 : Administer vNetwork Distributed Switch Settings

Objective 2.3 – Deploy and Maintain Scalable Virtual Networking

Understand the NIC Teaming failover types and related physical network settings There are 5 NIC Teaming policies: Route based on the originating virtual switch port ID This is the default configuration and the one that’s most commonly used. It works by choosing Continue reading Objective 2.3 – Deploy and Maintain Scalable Virtual Networking

Objective 2.5 – Build Performance Requirements into the Logical Design

Knowledge Understand what logical performance services are provided by VMware solutions. Memory Transparent Page Sharing (TPS) – most guest virtuals will be using the same Operating System and drivers etc, this means there will be allot of identical data in Continue reading Objective 2.5 – Build Performance Requirements into the Logical Design

Objective 2.4 – Build Manageability Requirements into the Logical Design

Knowledge Understand what management services are provided by VMware solutions. vMA vCenter PowerCLI vCLI vCenter Orchestrator vSphere API vSphere HA vSphere DRS Auto Deploy Scheduled Tasks Host Profiles Identify and differentiate infrastructure qualities (Availability, Manageability, Performance, Recoverability, Security) See Previous Continue reading Objective 2.4 – Build Manageability Requirements into the Logical Design

Objective 2.3 – Build Availability Requirements into the Logical Design

Knowledge Understand what logical availability services are provided by VMware solutions. VMware High Availability – minimizes downtime by restarting virtual machine on remain hosts in case of hardware failure VMware Fault Tolerance – Provides continuous availability in case of hardware failure by running a Continue reading Objective 2.3 – Build Availability Requirements into the Logical Design

VCAP5-DCD Objective 2.2 – Map Service Dependencies

Knowledge Identify basic service dependencies for infrastructure and application services. This will be done during the current state analysis, There are products that will help identify application dependencies like VMware vCenter Application Discover Manager or even VMware Infrastructure Navigator can highlight dependencies. For example a Continue reading VCAP5-DCD Objective 2.2 – Map Service Dependencies

vCenter 5.1 Performance Statistics only go back 30 days

Came across this bug the other day and thought I might put it up here so it may help other people. unfortunately I was asked to grab some performance statistics going back to last year. lucky I was running vCOPS which had the data Continue reading vCenter 5.1 Performance Statistics only go back 30 days

VCAP5-DCD Objective 2.1 –Map Business Requirements to the Logical Design

Knowledge Explain the common components of logical design. The common components of a Logical Design are: Focuses on satisfying the design factors (requirements, risks, constraints  assumptions) relationships between all major infrastructure components How to arrange components Does not contain physical detail like ports or ip addresses etc Continue reading VCAP5-DCD Objective 2.1 –Map Business Requirements to the Logical Design

VCAP5-DCD Objective 1.3 – Determine Risks, Constraints, and Assumptions

Differentiate between the general concepts of a risk, a requirement, a constraint, and an assumption. Risk – is a exactly what it sounds like a risk that might prevent a projects goals or requirements from being completed. An example of this is Continue reading VCAP5-DCD Objective 1.3 – Determine Risks, Constraints, and Assumptions

VCAP5-DCD Objective 1.2 – Gather and analyze application requirements

Given a scenario, gather and analyze application requirements This is what would be included in your current-state analysis  For example we have a scenario where we have been told to virtualise all exchange servers. we would: Capture baseline performance metrics including Continue reading VCAP5-DCD Objective 1.2 – Gather and analyze application requirements
