Simulating a connection
Storage Mirroring Recover offers a simple way for you to simulate a connection in order
to generate statistics that can be used to approximate the time and amount of bandwidth
that the connection will use when actively established. This connection uses the TDU
(Throughput Diagnostics Utility), which is a built-in null (non-existent) target to simulate a
real connection. No data is actually transmitted across the network. Since there is no
true connection, this connection type helps you plan your implementation strategy.
Before and after simulating your connection, you should gather network and system
information specific to Storage Mirroring Recover operations. Use the DTInfo utility to
automatically collect this data. It gathers Storage Mirroring Recover log files; Storage
Mirroring Recover and system settings; network configuration information such as IP,
WINS and DNS addresses; and other data which may be necessary in evaluating
Storage Mirroring Recover performance. The DTInfo utility can be found on the product
CD or in the Storage Mirroring Recover installation directory.
1. From the source where you will be running the TDU, run DTInfo.exe. It may take
several minutes for DTInfo to finish processing. After DTInfo processing is
complete, a \support subdirectory will automatically be created in the Storage
Mirroring Recover installation directory. A .zip file will contain the information
gathered. The file name is based on the machine name. To distinguish this file
from the next time you run DTInfo, append a unique identifier, perhaps the date
and time, to the end of the file name.
2. Make sure you have created a replication set that contains the data you want to
protect.
3. From the Replication Console , open the Connection Manager to establish the
connection.
l
Highlight the replication set and select Tools, Connection Manager.
l
Right-click on the replication set and select Connection Manager.
4. The Connection Manager opens to the Servers tab. Depending on how you
opened the Connection Manager, some entries on the Servers tab will be
completed already. For example, if you accessed the Connection Manager by
right-clicking on a replication set, the name of the replication set will be displayed
in the Connection Manager. Verify or complete the fields on the Servers tab.
