Janus 8850 24 bay SATA II to U320 SCSI  |  |
Description New! The 4U Janus 8850 is designed for superior enterprise performance. Its new Power PC 440SP controller CPU, SATA II internal architecture, and possible 4GB cache provides optimum transfer speed. Standard with RAID6 or TP protection, which allows for the simultaneous failure of 2 or even 3 hard drives without data loss. Operating system independent & transparent with Windows, Linux, Novell, UNIX, or Mac based servers. On-line expansion allows the user to add drives to an existing array without interrupting operation. Available with a battery backup. Dual flash ROM onboard. 3 year parts and labor warranty with 5 year warranty option. The Janus8850S contains the following built-in functions: - Disk Self Test: This function tests the health of hard drives with them installed in the RAID unit. DST performs write tests, servo analysis, and read scan tests; the test results are then displayed on the LCD and hyperterminal output. This can aid the user in deciding whether or not to replace a suspected failing hard drive.
- Disk Scrubbing: The data and/or parity stored on hard drives can sometimes become corrupted; this data can also reside in areas that are not accessed for long periods of time. DS will use idle time to test the disks, and if a sector is found to be corrupted, the data will be regenerated from other RAID member disks and will be written to an uncorrupted sector. The purpose of DS is to prevent the possibility of having multiple corrupted sectors in a single stripe, which is one of the main causes of data loss.
- Disk Cloning determines when to begin cloning a bad drive to a hot spare. Upon completion of cloning, the new cloned disk can take the position of the failing disk or can stand-by until the original disk fails, then take the failed disk's position. Disk cloning helps prevent a rebuild from ever occurring, keeping the unit from entering a degraded rebuild mode.
- Array Recovery Utility (ARU) aids a user in the event of multiple drive failures corrupting the RAID array of a Logical Disk and/or volumes. The ARU enables user’s online recovery of lost disk members of a Disk Group, and will automatically recover Logical Disks and Volumes.
