Configure and Manage DHCP/DNS/NAT Understand proper use and addition of a DHCP IP Pool NSX Edge supports IP address pooling and one-to-one static IP address allocation. Static IP address binding is based on the vCenter managed object ID and interface ID of the requesting client. NSX Edge DHCP service adheres to the following guidelines: Listens […]
Objective 6.1: Configure and Manage Logical Load Balancing Describe and understand when to use the two topologies for load balancing NSX edge LB enables net traffic to pass through multiple paths to a specific destination, to optimal resource optimization. It handles traffic up to L7, mapping eternal (or public) IP address to a set of […]
Objective 5.4: Configure and Manage Logical Routers Dynamic routing provides the necessary forwarding information between layer 2 broadcast domains, thereby allowing you to decrease layer 2 broadcast domains and improve network efficiency and scale NSX extends this intelligence to where the workloads reside for doing East-West routing. This allows more direct virtual machine to virtual […]
Objective 5.1: Create and Administer Logical Switches Given a scenario, demonstrate the proper way to add/remove a logical switch and Determine use case for and contrast the three Control Plane Modes A logical switch is distributed and can span arbitrarily large compute clusters. This allows for virtual machine mobility (vMotion) within the datacenter without limitations of […]
Data protection is still a challenge for many companies which are looking for a solution to perform backup data and do more. My last research about backup solutions landed to Vembu: an interesting solution that, near plenty ways and technical elements to protect data, offers an interesting set of tools to give a strong hand […]
Objective 4.3: Upgrade Existing vCNS/NSX Implementation Based on a given upgrade scenario, identify requisite steps and components for upgrading to NSX 6.x Before you install or upgrade NSX, consider your network configuration and resources. You can install one NSX Manager per vCenter Server, one instance of Guest Introspection and Data Security per ESXi host, and […]
Objective 4.1: Configure Environment for Network Virtualization Comprehend physical infrastructure configuration for NSX Compute, Edge and Management clusters (MTU, Dynamic Routing for Edge, etc.) Physical infrastructure configuration: MTU: must be >=1600 (configure it at switch and vSwitch level). Note: quite all new switches uses have preconfigured jumbo frames (9000 bytes), check switch vendor documentation before […]
Objective 3.2: Configure and Manage vDS Policies Compare and contrast common vDS policies Virtual Switch Objects Where Policies Apply for vSphere Distributed Switch: Distributed port group –> When you apply policies on a distributed port group, the policies are propagated to all ports in the group Distributed Port –> You can apply different policies on […]
Today server virtualization is standard de facto, adopted in small and large companies to guarantee the best available system manageability and efficiency. The problem of the caring systems in some disruptive situations, like physical replacement, system updates and service availability seems definitely solved using a VM instead physical systems. In the same time, the need […]
After half a year from my first Silicon Valley experience during Cloud Field Day 2, I’ve gathered some useful info like trends, news and hints in cloud strategies of this last years. While a lot of companies already adopted public cloud environment for their IT service or as a way to start new business, a […]
