What happens in the event of a hard disk drive failure?
Although Kaleidescape uses high quality hard disk drives, drives do fail occasionally. On average, drives in Kaleidescape Systems fail at a rate of one or two percent per year. To prevent loss of information from a drive failure, every Kaleidescape Server uses RAID-K to store redundant information. The 3U Server also features a Hot Spare Disk Cartridge as an additional measure of data protection. If a disk drive fails, then the LED on the Disk Cartridge with the failed drive changes from blue to amber (or does not light up at all) and Kaleidescape automatically receives an alarm message via the Internet. Kaleidescape then notifies the customer’s installer. The customer will see a message on the onscreen display and Web Utility saying “Disk is missing or damaged” or “Disk has failed; please phone your dealer”. The Kaleidescape System continues to operate and the customer can still enjoy all the Movies and Music in their library, but the Server will no longer be able to import CDs or DVD
