Areca Adds RAID Controller Firmware New Advanced Configuration

 
 

Taipei, Taiwan, - April 13, 2018 - Areca Technology Corporation (ARECA), a leading provider of internal, external and Thunderbolt RAID controllers, today announced the enhanced configuration features in the new version firmware. This new enhanced features include RAID 1-Multi Mirroring and Mirrored Pass-Through Disks that delivery a truly innovative hardware triple disks mirror solution.

Usually RAID 1-Simple Mirroring uses just two disks in a mirror. A third disk in the mirror set would permit active double-redundancy like with RAID-6, but without the overhead of parity generation, so better performance at lower cost. You can set up a RAID 1-Multi Mirroring or Mirrored Pass Through three disks system so that it mirrors data onto three identical disks all mirrored. If you combine an SSD and HDDs in a Mirrored Pass-Through, RAID1-Simple Mirroring or RAID 1-Multi Mirroring hybrid solution, the reads are obtained from the SSD with SSD speed. You don’t need to use OS and/or Software to create the copies of your data across multiple drives.

RAID 1-Multi Mirroring

RAID 1-Multi Mirroring is also known as “triple disk mirror”; data written on one disk drive is simultaneously written to another two disk drives. Read performance will be enhanced if the array controller can, in parallel, access all members of multi mirrored drives. During writes, there will be a minor performance penalty when compared to writing to a single disk. If one or two drive fails, all data (and software applications) are preserved on the healthy drive. RAID 1-Multi Mirroring writes three copies of everything, but its data storage capacity effective is 33.3%.

Mirrored Pass-Through Disk

Pass-through disks are attached to a RAID controller and operate as if they were attached to a non-RAID controller. No RAID configuration structure is stored on these physical disks. This feature is primarily targeted for users moving physical disks containing data from non-RAID controllers to RAID controllers. The disk is available directly to the operating system as an individual disk. It is typically used on a system where the operating system is on a disk not controlled by the RAID controller firmware. A mirrored pass-through disk means controller will be regarded as the hard disk clone function, a host’s data will write simultaneously into dual or triple hard disks in the RAID controller. Triple pass-through means “save three copies of the data such that you can survive two disks failure and still have everything."
