Here's a detailed explanation of each requirement:
C. Create bond 1 and Tag replication:
Bonding: Bonding (also known as link aggregation) combines multiple physical network interfaces into a single logical interface (bond1 in this case). This provides redundancy and increased bandwidth for replication traffic. If one physical link fails, replication can continue over the remaining links in the bond.
Tagging: Tagging replication traffic (usually with a VLAN tag) ensures that it is properly routed over the network and isolated from other types of traffic. This helps maintain performance and security for replication.
D. Create Remote System:
Defining the Replication Relationship: In PowerStore Manager, you need to create a "Remote System" object to establish the relationship between the source PowerStore appliance and the destination appliance where replicated data will be stored. This involves specifying the management IP address and credentials of the remote system.
E. Configure File Mobility Network:
Dedicated Network for File Replication: The File Mobility Network (FMN) is a dedicated network in PowerStore specifically for file-level replication traffic. It consists of three additional IP addresses per PowerStore cluster that utilize the existing management network VLAN, gateway, and netmask. These interfaces are mapped to the 1 GbE management ports, sharing the physical port with the existing management interfaces. 1
Isolation and Performance: Using a separate network for file replication ensures that this traffic doesn't interfere with other network activities, such as iSCSI or user access to file shares. This helps maintain optimal performance for both replication and other operations.
Why the other options are incorrect:
A. Create FC zoning between PowerStore: FC zoning is used for block-level storage access (like Fibre Channel SAN), not for file-level replication over Ethernet.
B. Configure Data Storage Network: While a Data Storage Network is essential for general storage traffic, it's not a specific requirement for configuring asynchronous file replication. File replication relies on the File Mobility Network.
