Remote Storage Centers and Replication QoS

Connecting to Remote Storage Centers

A remote Storage Center is a Storage Center that is configured to communicate with the local Storage Center over the Fibre Channel

and/or iSCSI transport protocols.

Storage Centers can be connected to each other using Fibre Channel, iSCSI, or both. Once connected, volumes can be replicated from

one Storage Center to the other, or Live Volumes can be created using both Storage Centers.

Connecting Storage Centers Using Fibre Channel

When Storage Centers are connected to the same Fibre Channel fabric and zoning is configured correctly, each Storage Center

automatically appears as a remote Storage Center; no additional configuration steps are required.

Steps

1. Connect both Storage Centers to the same Fibre Channel fabric.

2. Configure Fibre Channel zoning to allow the Storage Centers to communicate. When communication is established, each Storage

Center automatically appears as a remote Storage Center.

Connecting Storage Centers Using iSCSI

The following tasks describe how to add and remove iSCSI connections to remote Storage Centers.

Configure an iSCSI Connection for Remote Storage Systems

Add an iSCSI connection to a remote Storage Center or PS Group if you want to transfer replication and/or Live Volume data using the

iSCSI protocol.

Prerequisites

• The Storage Center or PS Group for which you want to configure iSCSI connections must be added to Storage Manager.

• Remote connections from Storage Center to PS Group require virtual fault domains.

• If the local Storage Center iSCSI ports are configured for virtual port mode and the ports are located behind a router that performs

network address translation (NAT), NAT port forwarding must be configured for the iSCSI fault domain.

• If you intend to use Challenge Handshake Authentication Protocol (CHAP) authentication for iSCSI replication traffic, the iSCSI fault

domains that are used for replication on each Storage Center have CHAP enabled.

About this task

NOTE: PS Groups do not support Live Volume.

Steps

1. Click the Storage view.

2. In the Storage pane, select a Storage Center or PS Group.

3. Open the Configure iSCSI Connection wizard.
