User’s Manual 1. Introduction to the ACS-77100 1.1. Overview The ACS-77100 RAID controller provides RAID 0 (striping), RAID 10 (Striping and mirroring) and RAID 5 (striping with parity) for you to construct a disk array optimized for performance or reliability. By connecting the SATA cables between the ACS-77100 and the disks, a RAID solution can be easily built. The ACS-77100 controller is equipped with Java-based GUI (graphical user interface) monitoring program, by which users ca

User’s Manual 1.3. Understanding RAID Levels 1.3.1. RAID 0 (striping) RAID 0 links each drive in the array to from one large drive. Storage capacity is determined by the smallest drive in the array. This capacity is then applied to format all other drive in the array. When using a 40GB, 50GB and a 60GB drive in a RAID 0 array, your system will have, in effect, one 120GB drive (40GB x 3) The diagram above represents the writing of data on a RAID 0 array composed of four disks

User’s Manual 1.3.2. RAID 10 (striping and mirroring) RAID 0+1 combines mirroring and striping functions on a minimum of four hard disks. Mirroring provides full redundancy and protects data in case of multiple drive failure (providing that data on one of each mirrored pair of drives is intact). The diagram shown represents the writing of data on a RAID 0+1 array composed of four DISKS connected to the controller. The controller creates two matching RAID 0 arrays on four DISKS

User’s Manual 1.3.3. RAID 5 (striping with parity) and RAID 5+hot spare RAID 5 uses a mathematical expression that compares data from three drives and calculates a fourth piece of data called “parity” which is saved on a fourth drive. Should one of the drives failed, parity data can be used to rebuild the failed data. Under RAID 5, parity data is stored across all drives in the array. This maximizes the amount of storage capacity available from all drives in the array while still pr
