NBU over FLEX network configuration
Hi Folks, I apologize in advance for the length of the text, as there are many details we wanted to share in order to expose our use case. Description: We have some questions regarding the network configuration of our NetBackup (NBU) infrastructure and its impact on Primary Server availability, WebUI access, and MSDPs replication. We would appreciate your guidance on the feasibility and best practices for our planned setup. Current Setup: DC1: Subnet 1: Contains all database (DB) and application servers, and is isolated from all other Subnets, even DC2's Subnet 1). Subnet 2: Used for virtualization management (vCenter) and inter-site communication (Routed with Subnet 3). Primary Server in DC1: Currently has a single interface in Subnet 1. Media Server in DC1: Configured in Subnet 1. DC2: Subnet 1: Contains DB and application servers (isolated from DC1’s Subnet 1). Subnet 3: Used for virtualization management (vCenter) and inter-site communication (Routed with Subnet 2). Primary Server (planned replication using Primary Server Availability from DC1): Intended to retain Subnet 1 IP but will need a new IP in Subnet 3. Media Server in DC2: Configured in Subnet 1 while the subnet was not yet isolated. Questions: Q1 Adding an Interface to the Primary Server in DC1 Our Primary Server in DC1 currently has an interface in Subnet 1. We want to add another interface in Subnet 2 to allow communication with nodes in that subnet and subnet 3 (Media Server from DC2). Is it feasible to add an interface to a Primary Server? Would this impact the accessibility of the NBU WebUI? If so, will the WebUI be accessible from both subnets or only from Subnet 1 IP that is already configured? Q2 Primary Server Availability Feature and IP Configuration in DC2 We intend to purchase the "Primary Server Availability" feature to replicate the Primary Server from DC1 to DC2. Since Subnet 1 exists in both DCs, we plan to keep the same IP for Subnet 1 in DC2. However, the second subnet does not exist in DC2—instead, we have Subnet 3. Can we configure the replication without impact, keeping the same Subnet 1 IP and assigning a new IP from Subnet 3 in DC2 in case of a Failover? Q3 Media Server Replication and Deduplication We plan to replicate backed-up data from DC1 to DC2 using deduplication. Initially, our Media Servers in both DCs were configured in Subnet 1 while inter-site communication was open. Now that Subnet 1 will be isolated, we must add an interface for each Media Server to allow communication between them: Subnet 2 for the Media Server in DC1, Subnet 3 for the Media Server in DC2 Does NetBackup require additional configuration to recognize and use the new interfaces for replication? Can we change the configured IPs (Subnet 1 of each Media Server) and set both for Subnets 2 and 3, while keeping Subnet 1 dedicated for DB and application backup? Sorry again for the length, we appreciate your advice on these points. Regards,
