Adtron ActiveRAID™ technology
In most RAID implementations, the host CPU and/or a separate RAID controller is involved in RAID disk management. This means that the storage is tightly coupled to the host CPU and that both the host CPU and the storage must be taken offline to support software upgrades or version changes. Adtron ActiveRAID™ technology moves RAID-0, RAID-1, and RAID-5 hard disk management to the storage subsystem level where it belongs in embedded applications. Incorporated in most Adtron Bladepak™ products, ActiveRAID technology frees the host CPU and its operating system to do its work. This eliminates the need for valuable processing cycles to be used for managing data storage and integrity and improves overall availability. The following animation demonstrates Adtron ActiveRAID technology in action.
With Adtron ActiveRAID technology, control of interleaving (RAID-0), mirroring (RAID-1) and redundant disks (RAID-5) occurs on the storage subsystem. Error handling, disk hot swapping and data rebuilding are handled by ActiveRAID onboard technology.
In contrast to other RAID implementations, ActiveRAID technology is interface independent and has been integrated with IDE, SCSI and Ethernet protocols. Isolation of the RAID function from changes in the host CPU and operating system protects your storage investment in embedded platforms, minimizing or eliminating the need to requalify when host systems change. In addition, during a disk drive failure, the isolation of the storage combined with RAID1 or RAID5 allows individual drives to be removed, replaced and rebuilt with no impact to on-going operations.
Tightly integrated with the Adtron SmartStorage™ architecture, ActiveRAID technology easily transfers to different form factors including 2.5-inch and 3.5-inch traditional hard disk drive footprints and PICMG industry standards such as cPCI and ATCA. Most high availability telecom, defense and industrial applications can benefit from ActiveRAID technology.
