1-2 Adaptec SCSI RAID 2120S/2200S Software User’ s Guide Chapter 3, Adaptec Storage Manager-Br owser Edition , provides an in- depth look at Adaptec Storage Ma nage r , an easy-to-use storage configuration application that supports both local and remote management.
1-3 Introduction Adaptec RAID controllers support the following types of array: RAID-0 A RAID-0 is cr eated by striping data ac ross two or more d isk drives.
1-4 Adaptec SCSI RAID 2120S/2200S Software User’ s Guide The cost of this redundancy is in efficient use of capacity , because all data is written to both drives, only half of the total capacity is available.
1-5 Introduction RAID-10 A RAID-10 is an example of a dual-level array and is created by using two or more equal-sized RAID-1s to cr eate a RAID-0. The top level RAID-0 shares the load among the second level RAID-1s, impr oving both r ead and write performance.
1-6 Adaptec SCSI RAID 2120S/2200S Software User’ s Guide RAID-50 A RAID-50 is a dual-l evel array created by usin g two or more equal-sized RAID-5s to create a RAID-0. The top level RAID-0 shares the load among the second-level RAID-5s, impro ving both read and write perf ormance.
1-7 Introduction RAID V olu me A RAID volume is created by joining two or more single-level arrays of the same RAID type. Unli ke dual-level arrays, the arr ays in a RAID volume do not have to be of equal capacity .
