Resource mapping creation on OceanStor ReplicationDirector

0

If the protected object is a FusionSphere VM, then map virtualization resources from the protected site to the disaster recovery site so that the VM can be recovered at the disaster recovery site based on the target attributes specified during resource mapping. For FusionSphere VMs, different resource mappings must be created due to differences in disaster recovery methods and applicable cloud platforms.
1. Storage replication disaster recovery
For VMs built on the FusionCompute cloud platform, you must create resource mappings for port groups and clusters/hosts.
For VMs built on the FusionManager cloud platform, you must create resource mappings for clusters and networks. Resource mappings for security groups are optional. If the VMs that require disaster recovery have been added into a security group, you must create resource mappings for that security group.
2. Host replication disaster recovery:
For VMs built on the FusionCompute cloud platform, you must create resource mappings for clusters/hosts, port groups, data stores, and Virtual Replication Gateways (VRGs).
For VMs built on the FusionManager cloud platform, you must create resource mappings for clusters, networks, and VRGs. Resource mappings for security groups are optional. If the VMs that require disaster recovery have been added into a security group, you must create resource mappings for that security group.
One resource at the production site or disaster recovery site can be mapped to only one resource of the same type. In remote disaster recovery mode, this operation must be performed at the production site.

Resource addition of OceanStor ReplicationDirector
If resources such as hosts or associated storage devices have been added to a new local site or remote site, ignore the resource addition step. If the required resources are unavailable when a site is created, or new resources need to be added during subsequent operations, perform the resource addition step.

Introduction to resource discovery of OceanStor ReplicationDirector
In order to provide disaster recovery for protected objects, OceanStor ReplicationDirector needs to discover the hosts where protected objects (such as databases) reside, storage devices associated with the protected objects, vCenter servers associated with the VMware virtualization environment, cloud platforms associated with Huawei virtualization environment, and VRG.

OceanStor ReplicationDirector positioning
The OceanStor ReplicationDirector (mainstream version: V100R003C10) is designed to manage the disaster recovery services of enterprise data centers. With the high application-aware capabilities and integrated value-added features of Huawei storage products, the OceanStor ReplicationDirector ensures service consistency during disaster recovery. The OceanStor ReplicationDirector helps users efficiently configure and monitor disaster recovery services and also conveniently perform data recovery and tests.

OceanStor ReplicationDirector features
The OceanStor ReplicationDirector (mainstream version: V100R003C10) has the following features: 1. Simplicity and high efficiency The OceanStor ReplicationDirector uses an application-based method to manage disaster recovery services and guides you through the disaster recovery service configurations step by step. It supports one-click disaster recovery test, planned migration, failover, and reprotection. 2. Visualization By graphically displaying the physical topologies of global disaster recovery and the logical topologies of service protection, the OceanStor ReplicationDirector enables you to easily manage the entire disaster recovery process. The execution status of protected groups and recovery plans is clear. 3. Integration The OceanStor ReplicationDirector integrates storage resource management. It meets the O&M requirements of various application scenarios, such as active-passive data centers, three data centers in two cities, and active-active data centers, reducing O&M costs and improving O&M efficiency. The OceanStor ReplicationDirector supports REST and SNMP v3 northbound interfaces, which can be connected to third-party systems. 4. Robust reliability The OceanStor ReplicationDirector ensures that the applications and data at the disaster recovery site are consistent with those at the production site. After the production site fails, the disaster recovery site immediately takes over services from the production site, ensuring service continuity. The multi-site deployment improves the reliability of the disaster recovery management system. The OceanStor ReplicationDirector backs up management data automatically so that the management system can be recovered rapidly in the event of a disaster.

OceanStor ReplicationDirector versions
The OceanStor ReplicationDirector has the following versions: 1. OceanStor UltraAPM V100R002C00 (The product name was changed to OceanStor ReplicationDirector in later versions.) 2. OceanStor ReplicationDirector V100R002C10 3. OceanStor ReplicationDirector V100R003C00 4. OceanStor ReplicationDirector V100R003C10
