RiOS Data Store
You can display and modify RiOS data store settings for the selected optimization policy on the Data Store page.
SteelHeads transparently intercept and analyze all of your WAN traffic. TCP traffic is segmented, indexed, and stored as segments of data, and the references representing that data are stored on the RiOS data store within SteelHeads on both sides of your WAN. After the data has been indexed, it is compared to data already on the disk. Segments of data that have been seen before are not transferred across the WAN again; instead a reference is sent in its place that can index arbitrarily large amounts of data, thereby massively reducing the amount of data that needs to be transmitted. One small reference can refer to megabytes of existing data that has been transferred over the WAN before.
General Settings
Encrypting the RiOS data store significantly limits the exposure of sensitive data in the event an appliance is compromised by loss, theft, or a security violation. The secure data is difficult for a third-party to retrieve.
Encrypting the RiOS data store can have performance implications; generally, higher security means less performance. Several encryption strengths are available to provide the right amount of security while maintaining the desired performance level. When selecting an encryption type, you must evaluate the network structure, the type of data that travels over it, and how much of a performance trade-off is worth the extra security.
For details about RiOS data store encryption and synchronization, see the SteelHead Management Console User’s Guide for SteelHead CX.
Complete the configuration as described in this table.
Control | Description |
Data Store Encryption Type | Select one of the following encryption types from the drop-down list. The encryption types are listed from the least to the most secure. • None - Turns off data encryption. • AES_128 - Encrypts data using the AES cryptographic key length of 128 bits. • AES_192 - Encrypts data using the AES cryptographic key length of 192 bits. • AES_256 - Encrypts data using the AES cryptographic key length of 256 bits. |
Enable Automated Data Store Synchronization | Enables automated RiOS data store synchronization. Data store synchronization ensures that each RiOS data store in your network has warm data for maximum optimization. All operations occur in the background and do not disrupt operations on any of the systems. |
Current Appliance | Select Master or Backup from the drop-down list. |
Peer IP Address | Specify the IP address for the peer appliance. You must specify either the IP address for the primary or auxiliary interface (if you use the auxiliary interface in place of the primary). |
Synchronization Port | Specify the destination TCP port number used when establishing a connection to synchronize data. The default value is 7744. |
Reconnection Interval | Specify the number of seconds to wait for reconnection attempts. The default value is 30. |
Enable Branch Warming for SteelHead Mobile Clients | Select the check box to enable branch warming for SteelHead Mobile Clients. By default, branch warming is enabled. |
Enable Data Store Wrap Notifications | Select the check box to enable data store wrap notifications. The default value is 1 day. |
Important: You must clear the RiOS data store and reboot the SteelHead service on the SteelHead after turning on, changing, or turning off the encryption type. After you clear the RiOS data store, the data cannot be recovered. If you do not want to clear the RiOS data store, reselect your previous encryption type and reboot the service. The appliance uses the previous encryption type and encrypted RiOS data store.
