Most businesses today need to retain a growing volume of valuable data that, although it is rarely accessed, must be readily available and retained for long periods of time. The IBM TotalStorage DS4100 Storage Server represents an entry-level server for cost-conscious enterprises that addresses storage needs without undue expense. Innovative design aspects include customer-replaceable components that can be repaired or upgraded without the need for tools and without the need to power down the server. Adding more storage capacity is as easy as inserting a new disk drive and folding down the locking handle. This easy process creates all power and signal connections and secures the new disk drive into place.
