United & Protected
FlexRAID is about Unifying & Organizing your data as well as Protecting & Recovering that data in case of disk failure.
Imagine a system with a number of disks as displayed here.
As you can see, it is a bit overwhelming from a usability standpoint.
Finding a file here requires browsing through multiple drives if one does not remember exactly which disk hosts what.
Additionally, this user has had to manually manage the free space across his disks.
Using FlexRAID, such a system can be cleaned up and properly protected.
In this transformation, FlexRAID took all the disks minus the OS disk and aggregated them into a single massive protected pool.
All your data under 1 unified and protected pool.
Works on your existing hardware
FlexRAID products transform anything from common household PCs to enterprise class storage JBODs into protected data pools. They enable you to Aggregate & Manage your data under a single Storage View while protecting that storage from data loss. All products include SMART Disk Monitoring such that you will be alerted either via email or SMS or both if anomalies are found.
FlexRAID offers you two products:
– A RAID over File System (RAID-F) solution that works above existing file systems to provide arbitrary data unit protection
– A Transparent RAID (tRAID) solution that transparently works underneath the file system at the block level to provide disk failure protection
Each takes a different approach to data protection in order to rip out particular benefits from each chosen protection strategy.
RAID over File System
RAID over File System is an extremely flexible and efficient system for large arrays of mostly static or semi-static data.
Rather than protecting disks, it only protects actual meaningful file data.
Because it is entirely agnostic to the storage medium, one can define the unit of risk to be practically anything including physical disks, unique file or set of files, folders, networks shares, removable media, etc.
A key feature of RAID over File System is its Snapshot RAID feature.
Snapshot RAID allows you to capture and protect data changes at scheduled times rather than at constant time. This allows for an extremely energy efficient system, in which only a single disk needs to be spinning during data access.
Whereas RAID over File System is not appropriate for storage arrays with dynamic data, Transparent RAID excels at protecting any type of data whether static or dynamic.
Transparent RAID provides real-time data protection with Live Data Reconstruction, Online RAID Expansion, RAID Contraction, Online Data Restoration, and Hot-Spare support.
Transparent RAID focuses on protecting whole physical disks and nothing else. It does so with efficiency and flexibility as its primary focuses.
Read operations in tRAID only need a single disk to spin while write operations requires at least two disks to spin. Slighly less as energy efficient as RAID-F, but vastly more efficient compared to standard RAID.
