6. er given today s usage the price of a disk machine has dropped dramatically whilst performance function significantly improved As the RAID HDD system is fault proof it is able to enhance data protection Having reconciled the disk machines its overall performance is also optimized thereby enabling it to become an essential equipment in an environment with the need for high performance jobs 2 2 1 RAID 1 also Disk Mirroring RAID 1 also known as Disk Mirroring provides a structure with two sets of HDDs that store the same kind of data When one of the sets is damaged operation under the other will continue With the change of a new HDD data will be automatically uploaded through an Auto Rebuild So long as the two HDDs do not malfunction simultaneously the system is able to function normally 3 1Installation 3 2 Installation Services 3 2 Installation Process 1 Stop running the machine and remove original HDD requires assistance of user to turn off power of machine and remove original hard disk 2 To administer synching hard disk copy all data from original hard disk to DTX 2100S Depending on condition of the disk the speed of copying is approximately 15M s 4 5G requires approximately 5 minutes 3 Run DTX 2100S 4 Re start machine E mail Welco me d atex fr Website www datex dsm com S A S au capital de 160 000 R C EVRY B 331 142 018 SIRET 331 142 018 00026 APE 725Z Int VAT n
