Accordance Introduces RAID for the Masses with its ARAID 3500 Hard Drive Subsystem
Accordance Systems today announced the ARAID 3500 advanced RAID controller and subsystem for hard drive data protection. The system utilizes a PC system’s existing system drive and dynamically builds a RAID 1 array with a blank secondary drive. Data is constantly mirrored on both drives, in the event one drive should fail the computer continues to run and no data is lost. The ARAID 3500 supports SATA drives and connects to PC SATA or IDE ports.
“TThe ARAID 3500 runs on any Windows, Macintosh, Linux or real-time kernel without additional device drivers or application software. The RAID intelligence is built into the device and is ready to run at high performance speeds out-of-the-box.
The ARAID 3500 provides operation status via an LCD display, audio alarm, email alert or optional SNMP network traps on each unit. ARAID warns users of any hard drive failure allowing drives and data to be replaced while the computer is still operating. In 2007, Google Inc. observed the annualized failure rates (AFR) of commercial PC hard drives varied from 1.7% to over 8.6% for drives in their 3rd year of operation. The ARAID 3500 represents the new approach for PC data backup
Each ARAID contains two removable hard drive trays allowing drives to be added or removed while the system is running. The ARAID allows drive trays to be taken from the system for archive back up storage in a similar manner as traditional computer storage tape. However, restoring systems is instantaneous as users only need to start systems from the archive drive and eliminate costly data rebuilds.
