Viewing cluster summary information

Complete the steps in this procedure to view summary information about a cluster including information about the associated quorum for the cluster.

The Summary page for the machine appears.

For information about viewing summary and status information for an individual machine or node in the cluster, see Viewing protected machines.

Configuring machine settings

Once you have added machines for protection in Rapid Recovery, you can easily view and modify the settings that govern the behavior of that protected machine. When you modify settings for a specific machine, those settings supersede the behavior set at the Core level.

You can view and configure the following machine settings in the Rapid Recovery Core Console:

The procedure for viewing or changing machine-level settings is identical for general, excluded writers, and license details. For more information, see Viewing and modifying protected machine settings.

The procedure for modifying nightly jobs for a machine is different. For information about configuring nightly job settings for a machine, see Customizing nightly jobs for a protected machine.

In some cases, you may want to adjust the data transfer rate for a protected machine. For more information, see About modifying transfer settings.

Viewing and modifying protected machine settings

Machine settings help determine the behavior of a machine protected by the Core. When you modify settings for a specific machine, those settings supersede the behavior set at the Core level.

Likewise, a protected Hyper-V virtual host has different machine settings than the virtual machines it manages. For more information, see

Complete the steps in this procedure to view and modify general settings, transfer settings, settings for excluded writers, and licensing settings for a protected machine.

NOTE: To view and modify nightly job settings, see Customizing nightly jobs for a protected machine.

The Settings page appears, showing settings for the selected machine. Optionally, to display setting categories from anywhere on the page, click the appropriate hyperlink on the left side of the page.

When you click on a setting you want to change, that setting becomes editable as a text field or a drop-down menu.

For each setting, when satisfied with your changes, click to save the change and exit edit mode, or click to exit edit mode without saving.

Table 84. General settings for a protected machine

Text Box	Description
Display Name	Enter a display name for the machine. This is the name that displays for a protected machine in the Rapid Recovery Core Console. You can enter up to 64 characters. By default, this is the host name of the machine. You can change this to something more user-friendly if needed. Do not use prohibited characters or prohibited phrases .
Host Name	This is the name of the protected machine as it appears in the machine's metadata.   NOTE: Do not change this setting, as doing so could break the connection between the protected machine and the Core.
Port	Enter a port number for the machine. The port is used by the Rapid Recovery Core service to communicate with this machine. The default port is 8006.
Encryption Key	If you want an encryption key that is already defined for this Rapid Recovery Core to be applied to the data for every volume on this protected machine, you can specify the encryption key here. The key must be unlocked. If no encryption keys exist, you can add an encryption key. For more information on managing encryption keys, see Managing encryption keys. If the volumes on this protected machine are encrypted, you can change to a different encryption key. Alternatively, you can disassociate an encryption key by selecting (none) from the Encryption key drop-down menu.   NOTE: After you apply an encryption key, change an encryption key, or disassociate an encryption key for a protected machine, Rapid Recovery takes a new base image upon the next scheduled or forced snapshot.
Repository	Select a repository for the recovery points. Displays the repository configured on the Rapid Recovery Core in which to store the data from this machine. The repository volume can be local (on storage attached to the Core server), or on a volume on a CIFS shared location.   NOTE: The Repository setting on this page can only be changed if there are no recovery points or if the previous repository is missing.

NOTE: For conceptual information about transfer settings, see About modifying transfer settings.

Table 85. Transfer Settings for a protected machine

Text Box	Description
Restore Default	This control restores all transfer settings to the system default settings.
Priority	Sets the transfer priority between protected machines. Enables you to assign priority by comparison with other protected machines. Select a number from 1 to 10, with 1 being the highest priority. The default setting establishes a priority of 5.   NOTE: Priority is applied to transfers that are in the queue.
Maximum Concurrent Streams	Sets the maximum number of TCP links that are sent to the Core to be processed in parallel per protected machine, for machines protected in a DVM repository.   NOTE: Quest recommends setting this value to 8. If you experience dropped packets, try increasing this setting.
Maximum Concurrent Writes	Sets the maximum number of simultaneous disk write actions per protected machine connection.   NOTE: Quest recommends setting this to the same value you select for Maximum Concurrent Streams. If you experience packet loss, set slightly lower—for example, if Maximum Current Streams is 8, set this to 7.
Use Core Default Maximum Retries	Select this option to use default retries number for each protected machine, if some of the operations fail to complete.
Maximum Segment Size	Specifies the largest amount of data, in bytes, that a computer can receive in a single TCP segment. The default setting is 4194304. Do not change this setting from the default unless directed to do so by a Quest Support representative.
Maximum Transfer Queue Depth	Specifies the amount of commands that can be sent concurrently. The default setting is 64. You can adjust this to a higher number if your system has a high number of concurrent input/output operations.
Outstanding Reads per Stream	Specifies how many queued read operations will be stored on the back end. This setting helps to control the queuing of protected machines. The default setting is 0.
Transfer Data Server Port	Sets the port for transfers. The default setting is 8009.
Transfer Timeout	Specifies in minutes and seconds the amount of time to allow a packet to be static without transfer.
Snapshot Timeout	Specifies in minutes and seconds the maximum time to wait to take a snapshot.
Snapshot Cleaning Timeout	Specifies in minutes and seconds the maximum time for process of deleting VSS snapshot on a protected machine.
Network Read Timeout	Specifies in minutes and seconds the maximum time to wait for a read connection. If the network read cannot be performed in that time, the operation is retried.
Network Write Timeout	Specifies the maximum time in seconds to wait for a write connection. If the network write cannot be performed in that time, the operation is retried.

NOTE: Because the writers that appear in the list are specific to the machine you are configuring, you will not see all writers in your list.

Changing the settings for a Hyper-V host or node

A Hyper-V host that is using Rapid Snap for Virtual (agentless protection) to protect VMs is indicated in the left navigation area by the host icon . The settings for a Hyper-V host with VMs that are protected agentlessly are not the same as a typical protected machine. All changes made to the settings for a host apply to the VMs on that host.

The setting you selected becomes editable, as a text field or a drop-down menu.

Table 87. General settings information

Text Box	Description
Display Name	The name that displays for a protected machine in the Rapid Recovery Core Console. You can enter up to 64 characters. By default, it is the host name of the machine. You can change the display name to something more user-friendly if needed. Do not use prohibited characters or prohibited phrases .
Host Name	The name of the protected machine as it appears in the machine's metadata.   NOTE: Do not change this setting, as doing so could break the connection between the protected machine and the Core.

NOTE: For best performance, it is recommended that the maximum concurrent transfers for the Hyper-V host or node be set to 1, which is the default setting.
