REO 4600 Product Description:
Affordable, scalable, flexible. When you need disk-based backup and recovery that provides uncompromising support for growth, deployment as VTL or disk volumes, all without breaking an IT budget, the REO 4600 is your choice. With the ability to scale from 3TB to 27TB and beyond through compression, the REO 4600 is an ideal choice for businesses of any size.
Overland Storage® REO Virtual Tape Library (VTL) software emulates multiple tape libraries over a Fibre Channel or iSCSI interface and seamlessly integrates with the existing backup infrastructure to enable cost-efficient long term retention on disk and more reliable, high-speed recoveries of backup data.
Unlike tape solutions and other disk-based back up systems, only the REO SERIES® includes REO ProtectionOS™ software, which embeds data protection intelligence. When configured as virtual tape, backup data is written sequentially and in large blocks, which results in greater backup performance.
Every REO SERIES system includes our 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.
REO 4600 appliances are compatible with all popular open systems and Windows-based backup software, physical tape drives and libraries and easily connect to existing Ethernet (iSCSI) and Fibre Channel networks for seamless integration without changes to existing backup processes. An intuitive and robust browser-based graphical user interface makes REO easy to configure and manage. Users can proactively monitor REO appliances and receive e-mail alerts for instant notification of status changes.
Highlights:
- User-defined functionality for Virtual Tape Library, Virtual Tape Drives and Disk Volumes (LUNs)
- Over 50 TB raw capacity, 100 TB useable compressed virtual tape capacity
- Compatible with all popular backup software
- Ethernet (iSCSI) and Fibre Channel connectivity
- Up to 6 virtual tape libraries and 512 virtual tape cartridges can be created and configured with up to 32 virtual tape drives (16 drives maximum per library)
- Up to 64 standalone devices can also be created utilizing a mix of virtual tape drives and/or disk volumes.
REO 4600 Hardware Compression:
The hardware compression option effectively doubles the useable virtual tape capacity of the REO 4600 and connected expansion arrays, making it the most cost effective way to store more backup data on disk. The combination of hardware compression and Dynamic Virtual Tape ensure REO is the most efficient and cost effective VTL available.

Software embedded in all REO SERIES appliances. Provides data protection intelligence, including virtualization, management, and connectivity. Also enables enhanced features via add-on software PACs (e.g. REO Multi-SitePAC)Hardware Compression
Effectively doubles the useable virtual tape capacity of the REO 4600 and connected expansion arrays. The combination of hardware compression and Dynamic Virtual Tape ensure REO is the most efficient and cost-effective VTL availableDrive Spin-Down
In order to conserve energy, drives can be spun-down into a sleep mode when they are not being accessed
Key Benefits:
Fast
The Overland REO 4600 disk-based backup and recovery appliance adds speed, reliability, and flexibility to any data protection environment. The REO 4600 features innovative Protection OS™ software that delivers volume and device virtualization, management, and connectivity capabilities. It also allows the REO to be easily enhanced via current and future software PAC optionsFlexible
It's easy to configure the REO 4600 as virtual tape libraries and/or any mix of standalone virtual tape drives or disk volumes (LUNs) for maximum flexibility. Patent-pending Dynamic Virtual Tape (DVT) 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 as needed to match the exact capacity requirements of the backup operation.Expandable
The REO 4600 offers tremendous flexibility in capacity, ranging anywhere between 6TB raw/5TB useable and 60TB raw/50TB useable (using 1TB drives and 4 expansion arrays). Expansion is facilitated by adding economical SAS connected expansion arrays in 6TB and 12TB configurations. Hardware compression effectively gives the REO4600 a total of 100TB useable compressed capacity without affecting performance or useable virtual tape capacity.Simple
The REO 4600 is also easy to deploy and manage. It's compatible with all popular open systems or Windows-based backup software, physical tape drives, and libraries, and it connects easily to Ethernet (iSCSI) or Fibre Channel networks. A simple browser-based interface, proactive monitoring, and remote management capabilities combine to make REO 4600 easy and cost effective to manage.
