Course notes for Windows Server 2016 (iv)

• High Availability:

  • Services: Ensuring continuous availability of services

    • A node with multiple deployments of the same service, typically using shared storage (distributed storage) to provide high availability of services

  • Type of service: Based on data manipulation and object-oriented

    • based on " Read Operation " Services: Access to the number of objects and connections: connection-based load balancing

    • DNS Polling : A domain name corresponds to multiple IP

    • HLB : Device-based load balancing: F5 (COST)

      • Third party

    • SLB : Application-tier-based load balancing

    • NLB : Network protocol-based load balancing

      • based on " Write Operations " services: Databases, virtual machines: Uniqueness of Write Objects

    • Failover Clustering: When a cluster node fails, the service is transferred to another available node, guaranteeing continuous availability of the service

  • physical: All physical nodes must use shared storage ( SAN , s2d )

  • Quorum: When a cluster node failure occurs: whether the cluster is working

    • Next active node

  • all cluster nodes: AM (activity Manager)

  •   based on voting mechanism: cluster node

    • quorum disk (folder): Contains all node information for the entire cluster , and is am give voting rights

• deployment of failover Clusters: compute nodes: CPU Number of cores

  • Memory size

  • Network card Bandwidth

  • Sum of resources for all nodes

• Network: Advanced: Planning a physical network:

  • Access network: Used to provide services

  • Heartbeat (cluster) network: Passing Heartbeat signals , passing write data (independent vlan

  • Storage network: Transfer data (standalone switch)

  • late: Planning for virtual Machine network

    • Virtual switches: Resource pools: Virtual switches from multiple nodes converge into one virtual pool, you can configure virtual network card auto-connect      

    • virtual network card

• storage: How to plan and connect storage spaces ( SAN , ISCSI , s2d )

  • Disaster Recovery and backup solutions

• Cluster Deployment operations: System Environment Preparation: computer name, network information: IP , MASK , GW , DNS

  • logical Environment: recommended AD domain environment: domain controller, node join domain

  • network Environment : Switches and network cards (physical & virtual), different networks of IP Sub-Network

  • Storage Environment: experiment: Configure ISCSI Services: Create a Virtual disk file for storing data

  • Define the use target object for this virtual store

• Backup: Local: Local media & Local network

  • Cloud Backup: Windows Azure Backup

  • Backup object: Virtual machine & Physical Machine

    • Database of services: whether the backup truncates the transaction log for the service database
