REO 1550 Product Description:
Big power in a slim profile’ is the calling card of the REO 1550. Many Overland customers find the REO 1550 is simply the most cost-effective way to incorporate robust disk protection capabilities across a wide range of applications. With support for up to 4 TB of capacity, the REO 1550 provides integrated software management capabilities, high performance, and full VTL support that can scale with your needs.
The REO® 1550 Disk-Based Backup and Recovery Appliance solves the challenges that IT professionals face exponential data growth, shrinking backup windows, the need for fast data recovery, new government regulations by providing fast, reliable data backup and recovery while reducing operating costs. The REO 1550 delivers reliable unattended backups and near-instantaneous file recovery in an easy to use, versatile appliance. Easily configured as a virtual tape library, standalone virtual tape drives, and/or disk volumes (LUNs), the REO 1550 can be easily deployed and modified to adapt to changing data protection requirements.
Unlike tape autoloaders, standalone tape drives, and other disk-based backup systems, only the REO SERIES® includes REO Protection OS™ software, which embeds data protection intelligence and enables future software enhancements via software PACs. It also provides a core set of volume and device virtualization, management, and connectivity features found only in REO SERIES appliances. When configured as virtual tape, backup data is written sequentially and in large blocks, which results in greater backup performance. In addition, REO SERIES virtual tape appliances are not susceptible to disk fragmentation, viruses, manual volume management, hackers, ongoing tuning, or file system overhead—all are common problems found with general purpose disk-based backup systems.
And only the REO SERIES includes patent pending Dynamic Virtual Tape™ (DVT) technology, which ensures that no storage capacity is wasted while eliminating the manual effort and guesswork of sizing, configuring, provisioning, and deleting virtual tape cartridges. With DVT, users can create virtual tape cartridges that automatically expand or shrink to match the exact capacity requirements of the backup operation. An intuitive and robust browser-based graphical user interface makes REO 1550 easy to configure and manage. Users can proactively monitor REO appliances and receive e-mail alerts for instant notification of status changes.

- User definable as virtual tape libraries, standalone virtual tape drives and/or disk volumes (LUNs)
