    Shutting Down the Appliance IMPORTANT: To ensure preservation of data on the REO 4600, you should not turn off the appliance using the Power button. Always use the Shut Down option located in the GUI.

  • Page 25: Backup Power

    Backup Power In order to protect your data from loss due to sudden power interruption, your REO 4600 supports the use of an external UPS. The unit monitors the UPS via the USB port (reporting the charge level on the System Summary page). When the REO 4600 senses a low UPS power condition, it initiates a graceful shutdown that completes before the UPS runs out of battery power.

  • Page 26: Behavior When Connected To Ups

    Behavior When Connected to UPS A REO 4600 with a UPS works normally as long as the main AC power is supplied. When the main AC power is interrupted and the REO 4600 detects battery power, it initiates a graceful shutdown in such a way as to be completed before the battery power runs out.

    (2 Gb or 4 Gb versions). Disk-to-Disk-to-Tape (D2D2T™) Backup Capabilities The REO 4600 is a storage resource used by a single backup server, or shared by multiple backup servers, using an Ethernet or FC network. Using standard backup software, you can copy backup data that resides on the REO 4600 to tape for long-term data retention.

    You select the type of tape emulation when you create the virtual tape device. Depending on the type of tape emulation you select, the disk drives on the REO 4600 appear to your backup software as LTO-2, LTO-3, or LTO-4 tape drives. Tape emulation simplifies the setup process while simultaneously providing data compression and the attributes of backing up data to disk.

  • Page 122: Appendix E - Initiators And Targets

    To configure the REO 4600 as a backup-and-recovery appliance, you must provide target and initiator information. Each volume on the appliance (REO 4600 device) is a target; the backup host servers are initiators. The initiator serves as a unique identifier across the network for communication setup.

  • Page 123: Ieee Iscsi Names

    You must assign targets and initiators to each other in pairs. This must be performed both on the REO 4600, by using the REO 4600 GUI, and on the application or backup server, by using the iSCSI initiator management tools. The following illustrations demonstrate how this should be accomplished in an iSCSI configuration using the Microsoft iSCSI initiator.
