Access data online, all the time

When you need access to your data, you don’t want to wait. StrongBox provides an always online file system that supports multiple, simultaneous requests. Data is never offline and users have a persistent view of all files in the archive, improving efficiency and maximizing the IT investment. Access is as simple as point and click from a standard file system. With unique performance tuning, you can customize data availability to meet specific business needs.

Reduce storage TCO

Data Growth

Minimize data center costs by leveraging low-power, low-cost LTFS media for long-term assets. StrongBox keeps data center power requirements low, reducing operational costs by up to 95 percent. As a protected archive for fixed data, StrongBox helps reduce additional storage investments while optimizing your infrastructure with policy-driven, automated tiering that matches performance and accessibility with business need.

Grow your archive with low-cost scalability

Data grows exponentially – budgets don’t. With StrongBox and LTO/LTFS storage, you can scale storage as needed. StrongBox XpanDisk allows users to increase the online disk storage capacity with the StrongBox NAS.

Simplify storage infrastructure with an easy-to-use solution

Unlike complex storage systems that require hours of configuration and training, StrongBox is a plug-and-play appliance that is simple to deploy. Seamlessly connecting to the network via GbE or 10GbE, StrongBox presents stored data just like a standard network share.

Stay in control of your data with LTFS and LTO - no vendor lock-in

You stay in control of your data with StrongBox. By leveraging the open standard LTFS technology, StrongBox writes data in a non-proprietary format and makes no modifications to files or metadata. A StrongBox system is not required to read data written by StrongBox – tapes can be exported and read by any LTFS drive.

Protect and preserve data with long-term reliability

Storage is fundamental, but ensuring that data can be retrieved is key to a successful IT infrastructure. StrongBox protects data on multiple fronts so that you can be confident that data written to the archive is recoverable in time of need.

Build a sustainable active archive

StrongBox is the turnkey solution component for active archive architectures in which your archival data remains available without high operating costs or bogging down network resources. StrongBox is energy efficient to help you meet Green IT initiatives, not to mention reduces your cost for power by up to 95 percent.

Tech Specs

StrongBox is easily configured and connected to your network with the ability to mount standard CIFS/NFS file shares. StrongBox uses an open SQL database to store and retrieve each file’s metadata, allowing the system to scale to billions of files with multiple copies for data protection. StrongBox is delivered as an appliance and connects to the host network via GbE or 10GbE. Simple connectivity to the tape system is accomplished via SAN (8Gb Fibre Channel) or directly with SAS. With two flexible models, businesses are empowered to choose the solution that works best and know that as a core capability, StrongBox can scale as needed with business growth.

Alleviate backup using StrongBox

Up to 90 percent of enterprise data isn’t accessed more than once, but still needs to be stored and protected long term. Protection typically involves backing up data to meet disaster recovery needs. But, inactive data that remains on primary storage media devours costly network, computing and power resources, while bogging down backup processes and straining the overall infrastructure.

Now you can simplify your backup process by moving fixed content into a StrongBox. StrongBox data is automatically protected, meaning that it doesn’t need to be backed up.

  • Remove 50-80% of data from your backup cycles
  • Protect data automatically
  • Maintain access to data, unlike traditional offline backup copies
  • Meet backup window and SLAs
