- Page 5 Important Safety Instructions, Care and Handling Before starting, take a few minutes to read this manual. Read all of these instructions and save this manual for later reference. Protect the disk array system from extremely high or low temperatures. Let the disk array system warm (or cool) to room temperature before using it.
- Page 6 The appliance must be grounded. The disk array system is equipped with a 3-wire grounded type of power cord. This power cord will only fit into a grounded type of power outlet. If an extension cord or a power center is used with the disk array system, make sure that the total current con- sumption of all products plugged into the wall outlet does not exceed the ampere rating.

Page 26: Raid 0
User’s Manual RAID 0 RAID 0 links each drive in the array as one huge drive. Storage capacity is determined by the smallest drive in the array. That capacity is then applied to format all other drives in the array. If using a 40 GB, 50GB, 60 GB, and 70 GB drive in a RAID 0 array, your system will see one huge drive of 160 GB (40 GB×4). -
Page 27: Raid 0+1
Chapter 2 – Before you begin RAID 0+1 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). RAID 0+1: Combination of mirroring and striping Characteristics: This configuration provides optimal speed and reliability. -
Page 28: Raid 5 And Raid 5+Hot Spare
User’s Manual RAID 5 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 fail, parity data can be used to rebuild the failed data. Under RAID 5, parity data is stored across all drives in the array. - Page 29 Chapter 2 – Before you begin The diagram below represents the writing of data on a RAID 5 array composed of four DISKS connected to the controller. Parity blocks are represented by the letter P. The diagram below represents the writing of data on a RAID 5+hot spare array composed of four DISKS connected to the controller.

I have connected the subsystem, but it does not appear in the motherboard BIOS. - Page 58 User’s Manual is R5. (1) Shut down and tune the RAID level selector to R5. or (2) Re-plug the four disks and re-create the Array to R0 (But data in the R5 disks will be lost due to the destructive init ) If I really want to re-create a new RAID.

Appendix B– Glossary Array See Disk Array. Array Management Software The body of software, that provides common control and management for a disk array. Array Management Software most often executes in a disk controller or intelligent host bus adapter, but may also execute in a host computer. When it executes in a disk controller or adapter, Array Management Software is often referred to as Firmware. - Page 64 User’s Manual Parity Parity information is redundancy information calculated from actual data values. If any single piece of data is lost, the data remaining and the parity information can be used together to compute the lost data. Parity information can either be stored on a separate, dedicated drive, or be mixed with the data across all the drives in the array.
