Strongbox LTFS Storage Solution


What is StrongBox?

StrongBox is a storage gateway solution that integrates storage tiers and technologies to simplify data management and enable the lowest-cost data preservation. StrongBox can be used as file-based, network-attached storage (NAS) or for object-based storage to support massively scalable data workloads.

StrongBox is the ultimate storage solution for unstructured data.

Performance Defined Storage

StrongBox's intelligent storage management provides the right performance to meet your applications and workflow requirements while maximizing cost savings to meet your budget. Create your perfect balance of storage performance and economics by fusing storage technologies (SSD, HDD and tape) into a seamless tier of storage.

Access data to meet business needs

When you need access to your data, you don't want to wait. StrongBox's unique policy tuning balances data availability with system efficiency. Users have a persistent view of all files and objects so that data can be recalled simply when needed.

Deploy with existing architecture

Connecting to the network via standard NFS, CIFS or S3 protocols, StrongBox provides an easy point for applications and users to access data directly as a standard file system, no special applications or agents needed. With a RESTful API and host of intrinsic tools for application integration, StrongBox can be deployed with your existing resources or as a stand-alone solution.

Scale file or object storage at the lowest cost

StrongBox provides file and/or object storage to provide the best of both worlds in one solution. Using the standard S3 protocol, users now have the ability to benefit from low-cost tape media for object storage efficiency, blended with the performance of disk to store or access data anywhere, at any time.

Control storage costs and reduce TCO

Data grows exponentially - budgets don't. With StrongBox and LTO/LTFS tape, you can scale storage as needed using the library of your choice or even add multiple tape libraries to increase storage capacity seamlessly managed behind a single StrongBox. Users can add FC/SAS disk arrays, such as StrongBox XpanDisk, to increase the nearline storage capacity.

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.

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 Data On and Offsite

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 is recoverable in time of need. You can protect data offsite by replicating to a secondary StrongBox or writing data to an offsite library.

Key data integrity and protection features include:

  • Pass-through tape encryption
  • File integrity check with HASH code validation
  • Intuitive system monitoring and health checks
  • Proactive self-healing

StrongBox provides touchless tape management by writing to multiple libraries, no manual involvement needed.

StrongBox Multi-Library

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 NAS appliance that is simple to deploy. Connecting to the network via GbE or 10GbE, StrongBox presents stored data just like a standard network share.

Build a sustainable active archive

StrongBox empowers an active archive architecture in which all 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. File transfers are managed via standard NFS, CIFS or S3 protocols. 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 or virtual machine (VM). Simple connectivity to the tape system is accomplished via SAN (8Gb Fibre Channel) or directly with SAS. With two flexible appliance 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
