About Resiliency Platform features and components
The following is a brief introduction to Veritas Resiliency Platform key components and their relationships. Administrators responsible for deploying and configuring the product need to understand these in more detail.
Resiliency Manager | The component that provides resiliency capabilities within a resiliency domain. It is composed of loosely coupled services, a distributed data repository, and a management console. The Resiliency Manager is deployed as a virtual appliance. |
Infrastructure Management Server (IMS) | The component that discovers, monitors, and manages the asset infrastructure within a data center. The IMS transmits information about the asset infrastructure to the Resiliency Manager. The IMS is deployed as a virtual appliance. To achieve scale, multiple IMSs can be deployed in the same data center. |
Replication Gateway | The component of Veritas Resiliency Platform Data Mover that is deployed as a virtual appliance on both data centers and used to perform replication between the data centers. If you plan to use any third party replication technology, you do not need to deploy Replication Gateway. |
Data Gateway | The component of Veritas Resiliency Platform that is deployed in AWS data center to enable replication using Object Storage. You need to deploy this component only if you plan to use Object Storage replication for recovery of your data center assets to AWS data center. See About Data Gateway. |
Resiliency Domain | The logical scope of a Resiliency Platform deployment that includes Resiliency Manager , IMS, and hosts in both the data centers. It can extend across multiple data centers. |
Data center | For a disaster recovery use case, the resiliency domain must contain at least two data centers in different locations, a source data center and a target data center. Each data center has a Resiliency Manager and one or more IMSs. If you are using Resiliency Platform Data Mover for replication, each data center must also have at least one Replication Gateway. |
Asset infrastructure | The data center assets that you add to Resiliency Platform for discovery and monitoring by the IMS. The asset infrastructure can include virtual machines, physical machines (Windows or Linux servers), virtualization servers for Hyper-V and VMware, and enclosures (storage arrays). Once the asset infrastructure is discovered by the IMS, the discovered virtual machines or applications are listed in the console as assets to manage or protect. |
Resiliency Group | The unit of management and control in Resiliency Platform. You organize related assets into a resiliency group and manage and monitor them as a single entity. |
Service objective | A template to define the type of operations and technologies that are supported for a group of assets. You apply a service objective to each resiliency group. A template which identifies the characteristics of a service. These could be availability related characteristics such as local redundancy, and number of nodes in a cluster or DR characteristics such as remote recovery, Recovery Point Objective (RPO) SLAs, rehearsal support etc. Service objective is applied when a group of assets are being added to a resiliency group. Resiliency Platform monitors the resiliency groups based on the service objective definition and raises the risks as applicable. |
NetBackup Server | The component that allows restoration of virtual machines to a local or remote data center using NetBackup generated backup images. You need to add this component only if you want to restore the virtual machines using NetBackup generated backup images. See About protecting assets with NetBackup using Resiliency Platform. |
Veritas InfoScale Operations Manager Management Server | Till version 3.4, this component allowed discovery of InfoScale applications that are already configured in Veritas InfoScale Operations Manager. From version 3.5 of Resiliency Platform, the discovery and management of InfoScale applications is performed via Infrastructure Management Server. From Resiliency Platform version 3.5, you cannot add Veritas InfoScale Operations Manager Management Server. |
Virtual Business Service (VBS) | A multi-tier business service where each VBS tier hosts one or more resiliency groups. A VBS lets you group multiple services as a single unit for visualization, automation, and controlled start and stop in the desired order. VBS uses the vertical grouping mechanism to group the multiple services. You can perform the disaster recovery operations on the entire VBS. |
