Managing Replication Operations

If you plan on performing replication operations across a firewall, the DR Series system replication service requires that

the following fixed TCP ports be configured to support replication operations:

注: To allow replication storage information to be viewed by a corresponding data management agent (DMA), the

target DR Series system needs to reside in the same domain as the source DR Series system in the replication

relationship.

• port 9904

• port 9911

• port 9915

• port 9916

注: If there are no existing containers, replication relationships, or any scheduled replication operations, the only

Replication-related option that is enabled is Create. The Edit, Delete, Stop, Start, Bandwidth, and Display Statistics

options are disabled (grayed out).

In the 2.0 release, DR Series systems support 32:1 replication of data. This means that multiple source DR Series systems

(up to 32) can write data to different individual containers on a single, target DR Series system.

注: Starting with release 2.0, the DR Series system software includes version checking that limits replication only

between other DR Series systems that run the same system software release version (DR Series systems running

Release 2.0.x software can only replicate with other DR Series systems that run the same release system

software). For example, Release 2.0.x systems will not be able to replicate with Release 2.1 or Release 3.0 systems,

but can replicate with systems running Release 2.0.0.1 or 2.0.0.2.

注: You need to be aware that the storage capacity of the target DR Series system is directly affected by the

number of source systems writing to its containers, and also by the amount being written by each of these source

systems.

创建复制关系

要创建新的复制关系，请完成以下操作：

1. 选择 Storage（存储） → Replication（复制）。

此时将显示 Replication（复制）页面，其中按以下类别列出了所有当前复制条目：

– Local Container Name（本地容器名称）

– Role（目标或源）

– Remote Container Name（远程容器名称）

– Peer State（联机或脱机）

– Bandwidth（复制带宽限制）

注: Bandwidth（带宽）为复制带宽限制，可将其设置为二进制千字节/秒 (KiB/s)、二进制兆字节/秒

(MiB/s)、二进制千兆字节/秒 (GiB/s) 或无限带宽（默认）。

2. 单击选项栏中的 Create（创建）。

此时将显示 Create Replication（创建复制）页面。

3. 在 Step 1: Select a local container（步骤 1：选择一个本地容器）中，从可用容器列表中选择一个本地容

器。

4. 在 Step 2: Select Encryption（步骤 2：选择加密）中，选择以下加密选项之一：None（无）、128-bit（128

位）或 256-bit（256 位）。
