the recovery points created by the snapshots. Due to the amount of data transmitted from core to

core, multiple parallel streams may be required to perform at wire speeds up to the speed of a 1GB

Ethernet connection.

NOTE: Bandwidth specified by the ISP is the total available bandwidth. The outgoing bandwidth

is shared by all devices on the network. Make sure that there is enough free bandwidth for

replication to accommodate the change rate.

• Number of Agents— It is important to consider the number of agents protected per source core and

how many you plan to replicate to the target. DL1000 lets you perform replication on a per-protected

server basis, so you can choose to replicate certain servers. If all protected servers must be replicated,

this drastically affects the change rate, particularly if the bandwidth between the source and target

cores is insufficient for the amount and size of the recovery points being replicated.

Depending on your network configuration, replication can be a time-consuming process.

The Maximum Change Rate for WAN Connection Types is shown in the table below with examples of

the necessary bandwidth per gigabyte for a reasonable change rate.

Broadband Bandwidth Max Change Rate

DSL 768 Kbps and up 330 MB per hour

Cable 1 Mbps and up 429 MB per hour

T1 1.5 Mbps and up 644 MB per hour

Fiber 20 Mbps and up 8.38 GB per hour

For optimum results, you should adhere to the recommendations listed in the table above. If a link

fails during data transfer, replication resumes from the previous failure point of the transfer once link

functionality is restored.

Steps For Configuring Replication

NOTE: The information below is presented as a high-level overview of the steps required to perform

replication. For complete procedures, go to the Dell DL1000 Appliance User’s Guide at dell.com/

support/manuals.

To replicate data using AppAssure, you must configure the source and target cores for replication. After

you configure replication, you can then replicate agent data, monitor and manage replication, and

perform recovery. Performing replication in AppAssure involves performing the following operations:

• Configure self-managed replication — For more information on replicating to a self-managed target

core, see topic 'Replicating to a Self-Managed Target Core' in the Dell DL1000 Appliance User’s

Guide.

• Configure third-party replication— For more information on replicating to a third-party target core,

see topic 'Process of Replicating to a Third-Party Target Core' in the Dell DL1000 Appliance User’s

Guide.

• Replicate an existing agent— For more information on replicating an agent that is already protected

by the source core, see topic 'Adding a Machine to Existing Replication' in the Dell DL1000 Appliance

User’s Guide.

• Consume the seed drive — For more information on consuming seed drive data on the target core,

see topic 'Consuming the Seed Drive on a Target Core' in the Dell DL1000 Appliance User’s Guide.
