The deployment specification details the design decisions covering physical design, sizing, and high availability for the DRaaS Connector appliances in the protected VMware Cloud Foundation instance.

DRaaS Connector Appliance

The DRaaS Connector appliance connects the VMware Cloud Disaster Recovery service to on-premises data centers. The DRaaS Connector is distributed as a virtual appliance in the Open Virtualization Format (OVF) standard.

A DRaaS Connector appliance is required in the protected VMware Cloud Foundation instance to manage the replication and synchronization of data between the VMware Cloud Foundation instance and the Cloud File System to enable recovery of business workloads in the event of a ransomware attack. You deploy the DRaaS Connector appliance in the management domain.

Note:

Depending on the number of virtual machines you protect, you might need to deploy multiple DRaaS Connector appliances to your VMware Cloud Foundation instance. For more details, see DRaaS Connector System and Network Requirements.

Decision ID

Design Decision

Design Justification

Design Implication

CBR-CDP-CFG-001

Deploy two DRaaS Connector appliances in the default management vSphere cluster.

Required to establish secure communication between the VMware Cloud Foundation instance and VMware Cloud Disaster Recovery.

The DRaaS Connector appliances must be able to connect to the internet through a firewall.

CBR-CDP-CFG-002

Protect the DRaaS Connector appliances by using vSphere High Availability.

Supports the availability objective without requiring manual intervention during an ESXi host failure.

None.

CBR-CDP-CFG-003

Place the DRaaS Connector appliances in a designated virtual machine folder.

Provides organization of the appliances in the management domain vSphere inventory.

You must create the virtual machine folder during deployment.

CBR-CDP-CFG-004

Apply vSphere Distributed Resource Scheduler anti-affinity rules to the DRaaS Connector appliances.

vSphere Distributed Resource Scheduler prevents the DRaaS Connector appliances from residing on the same ESXi host and impacting the performance of replications.

  • You must perform an additional configuration to set up an anti-affinity rule.

  • For a default management vSphere cluster that consists of four ESXi hosts, you can put in maintenance mode only a single ESXi host at a time.

Decision ID

Design Decision

Design Justification

Design Implication

CBR-CDP-CFG-005

When using two availability zones, add the DRaaS Connector appliances to the VM group of the first availability zone.

Ensures that the DRaaS Connector appliances run in the primary availability zone hosts group.

After the implementation of the second availability zone for the management domain, you must update the VM group for the primary availability zone virtual machines to include the DRaaS Connector appliances.
