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

VCAP5-DCD Objective 1.1 – Gather and analyze business requirements

Associate a stakeholder with the information that needs to be collected. Before  a design can begin the correct information needs to be collected, this information needs to be collected and associated with particular stakeholders. GATHER (information) – DEFINE (requirements) – IDENTIFY(constraints, risks Continue reading VCAP5-DCD Objective 1.1 – Gather and analyze business requirements

VCAP5-DCA Objective 2.2 : Configure and Maintain VLANS, PVLANs, and VLAN Settings

Determine use cases for and configure VLAN Trunking VLAN trunking is where you allow multiple VLANs to run over a single port…. Simple When this comes up most people just talk about the physical VLAN trunking which carries the physical up-links from Continue reading VCAP5-DCA Objective 2.2 : Configure and Maintain VLANS, PVLANs, and VLAN Settings

VCAP5-DCA Objective 2.1 : Implement and Manage Complex Virtual Networks

Configure SNMP SNMP (Simple Network management Protocol) is available and supported by basically all devices in the IT world most people would reffer to it as SNMP trap which is an alert sent by an SNMP agent to a management Continue reading VCAP5-DCA Objective 2.1 : Implement and Manage Complex Virtual Networks
