Working with VDCs in the ECS Portal

An ECS virtual data center (VDC) is the top-level resource that represents the collection of ECS infrastructure components to manage as a unit.

You can use the Virtual Data Center Management page available from Manage > Virtual Data Center to view VDC details, to create a VDC, to edit an existing VDC, to update endpoints in multiple VDCs, delete VDCs, and to federate multiple VDCs for a multisite deployment. The following example shows the Virtual Data Center Management page for a federated deployment. It is configured with two VDCs named vdc1 and vdc2.

You can use the Virtual Data Center Management page available from Manage > Virtual Data Center to:

Table 1. VDC properties
Field Description
Name The name of the VDC.
Type The type of VDC is automatically set and can be either Hosted or On-Premise.
  • A Hosted VDC is hosted off-premise by a third-party data center (a backup site).
Replication Endpoints Endpoints for communication of replication data between VDCs when an ECS federation is configured.
  • By default, replication traffic runs between VDCs over the public network. By default the public network IP address for each node is used as the Replication Endpoints.
  • If a separate replication network is configured, the network IP address that is configured for replication traffic of each node is used as the Replication Endpoints.
  • If a load balancer is configured to distribute the load between the replication IP addresses of the nodes, the address that is configured on the load balancer is displayed.
Management Endpoints Endpoints for communication of management commands between VDCs when an ECS federation is configured.
  • By default, management traffic runs between VDCs over the public network. By default the public network IP address for each node is used as the Management Endpoints.
  • If a separate management network is configured, the network IP address that is configured for management traffic of each node is used for the Management Endpoints.
Status The state of the VDC.
  • Online
  • Permanently Failed: The VDC was deleted.
Actions The actions that can be completed for the VDC.
  • Edit: Change the name of a VDC, the VDC access key, and the VDC replication and management endpoints.
  • Delete: Delete the VDC. The delete operation triggers permanent failover of the VDC, You cannot add the VDC again by using the same name. You cannot delete a VDC that is part of a replication group until you first remove it from the replication group. You cannot delete a VDC when you are logged in to the VDC you are trying to delete.
  • Fail this VDC:
    WARNING:  Failing a VDC is permanent. The site cannot be added back.
    NOTE: Fail this VDC is available when there is more than one VDC.
    • Ensure that Geo replication is up-to-date. Stop all writes to the VDC.
    • Ensure that all nodes of the VDC are shutdown.
    • Replication to/from the VDC will be disabled for all replication groups.
    • Recovery is initiated only when the VDC is removed from the replication group. Proceed to do that next.
    • This VDC will display a status of Permanently Failed in any replication group to which it belongs.
    • To Reconstruct this VDC, it must be added as a new site. Any previous data will be lost, as that data will have failed over to other sites in the federation.
