Before You Start

This section describes the basic environmental requirements for configuring and managing InfoReplicator.

No matter when you configure InfoReplicator for the first time or manage it during routine maintenance, you must know the following basic environmental requirements of InfoReplicator.

Time Synchronization

When InfoReplicator is used to replicate data, it takes the primary system as the baseline, that is, it replicates data from the primary system to the secondary system without synchronizing the time between the two OceanStor 9000 storage systems. These storage systems do not need to use the same external Network Time Protocol (NTP) server. Because of this, you can easily manage data replication over a long distance between storage systems at different locations.

When InfoLocker is configured for the primary and secondary systems, the write once read many (WROM) clock of the two systems must be consistent (that is, the clock difference is smaller than 60 minutes) and the protection periods for WORM root directories must be the same.

User Authentication

InfoReplicator supports local and domain authentication. These two authentication modes have their own requirements. If any requirement is not met, access will be denied due to insufficient permission.
  • When the local authentication mode is used, the local authentication users of the primary and secondary OceanStor 9000 storage systems must have the same UID and GID.
  • When the domain authentication is used, the primary and secondary OceanStor 9000 storage systems must be added to the same domain.
  • If there is a CIFS-NFS cross-protocol share access scenario, the primary and the secondary OceanStor 9000 must join the same domain and configure the same domain information. You must configure the same user mapping rule and mapping mode.

Network Requirement

InfoReplicator uses the front-end service network to transmit data from between the primary and secondary OceanStor 9000 storage systems. Therefore, data can be replicated only when the front-end service networks of the primary and secondary OceanStor 9000 storage systems can communicate with each other. To manage all storage systems using the same maintenance terminal, ensure that the management networks of the primary and secondary OceanStor 9000 storage systems can communicate with each other and the following TCP ports are available:
  • TCP 22: Used for the SSH login to the operating system of storage nodes.
  • TCP 8088: Used for the HTTPS login to DeviceManager.

Because the initial synchronization is a full synchronization that replicates all data of the primary system to the secondary system and requires a high network bandwidth, you must ensure sufficient bandwidth for the initial synchronization for it to complete as quickly as possible to minimize the impact on system performance.

Backup Requirement

In addition to InfoReplicator, the OceanStor 9000 supports multiple data protection functions to meet the varying backup requirements, for example, InfoStamper snapshot, InfoMigrator, and NDMP backup. You can choose one or more from these functions of the OceanStor 9000 according to your backup scenarios.
  • InfoReplicator: Used for data replication between two OceanStor 9000 storage systems.
  • InfoStamper: Used for data backup within one OceanStor 9000 storage system.
  • InfoMigrator: Used for data backup between an OceanStor 9000 storage system and an external server (such as a common Linux server).
  • NDMP backup: Used for data backup between an OceanStor 9000 storage system and another backup media such as a tape library.
