Preface The Overland Storage REO 9000 Disk-Based Backup-and-Recovery Appliance takes the lag time, expense, and burden out of backing up critical data and works seamlessly within current storage environments. The REO Appliance performs faster than traditional disk-based storage methods and serves as a shared network resource by utilizing high- capacity disks, high-speed Ethernet and Internet SCSI (iSCSI) connectivity, and unique software intelligence capability from Overland Storage. The R

Reviewing REO 9000 Concepts 1 CHAPTER and Requirements The main steps involved in preparing to set up the REO Appliance include: Step 1 Understanding the concepts of iSCSI, Fibre Channel (FC), disk-to-disk- to-tape (D2D2T) backup, redundant array of independent disks (RAID), tape emulation, logical volume management (LVM), and how the REO Appliance fits into the picture. Step 2 Reviewing the requirements that your servers and network must meet to ensure successful installation and operation

Overland Storage REO 9000 with ProtectionPAC Software Fibre Channel (FC) Instead of, or in addition to, using iSCSI and the TCP/IP protocol to transmit information over a network, you also have the option of using a SAN that makes use of the FC and Small Computer System Interface (SCSI) protocols. The FC protocol uses two additional protocols to communicate at the hardware level: Fibre Channel Arbitrated Loop (FC- AL), which communicates with hubs, and Fibre Channel Switched (FC- SW), which

Setup Guide Disk-to-Disk-to-Tape (D2D2T) Backup Capabilities The REO Appliance is a storage resource used by a single backup server or shared by multiple backup servers using an Ethernet or FC network. By using standard backup software, you can copy backup data that resides on the REO Appliance to tape for long-term data retention. The following illustration shows application servers sending backup data over a 10/100 or Gigabit Ethernet (GbE) LAN to backup servers sharing REO Appliance D2D

Overland Storage REO 9000 with ProtectionPAC Software If you use a RAID 5 configuration, you can also set aside a disk drive for each physical host (controller); that is, you can create a hot spare. These disk drives remain in standby mode, and you can use them immediately if another disk fails. Tape Emulation The ProtectionPAC software includes two tape emulation features, which you can use to create virtual linear tape-open (LTO-2) tape devices that provide 2-to-1 compression ratios with

Setup Guide Network For best results, Overland Storage strongly recommends that you use a dedicated GbE network to share the storage resources on the REO Appliance among multiple backup servers. To ensure optimum performance, always use the appropriate patch cables to connect the REO Appliance to the backup-server storage network. To select the appropriate cables, use the following guidelines: If you intend to use GbE, you must use Category 5E (or better) cables for GbE connections. You ca

Overland Storage REO 9000 with ProtectionPAC Software Setting the SCSI Time-Out Value in Windows Environments If you intend to use your REO Appliance in a Windows environment, be aware that there are certain operating conditions in which time-out errors might occur. These errors usually result in the system reporting a disk failure for the associated REO Appliance disk drive or drives. (These errors might be reported as iSCSIPrt errors in the System Log of the Event Viewer. Examples includ
