All Data Protection Solutions by Arco products are operating system independent and require no system resources. This is possible thanks to our unique patented DupliDisk (DD) technology which is embedded within each product. The fourth generation of this innovative hidden device technology, DD4, was released in 2005.
No Impact on System Performance
DPS-Arco products are all hardware RAID based. This means there is no impact on system performance. Unlike software RAID which uses the host processor for RAID functions--and slows overall performance considerably, our hardware RAID devices plug directly into the ATA bus of the host computer.
The advantages:
• Our products require no drivers, IRQ’s, TSRs or SysTray resources.
• Our products are hardware and OS independent.
• Our DupliDisk technology is completely transparent to the host system.
• Our products provide a constant mirror of all data and provide automatic failover
Constant Disk Mirroring
The host system writes data to the DPS-Arco hardware RAID device as though it were an ordinary hard drive. The device passes the data writes through simultaneously and securely to both hard drives, thereby maintaining a constant mirror of all data. This is done at the block level so it does not matter what the data is or how the drives are formatted.
If a hard drive should fail, the DPS-Arco hardware RAID device automatically switches to the remaining drive and alerts the user that a drive has failed. The computer system remains up and running normally. Then, depending on the model, the user can either hot-swap out the failed drive or bring the system down at a convenient time to replace the drive and re-mirror in the background.
