A Logical Volume with Logical Drives of Different Levels? Multi-level RAID Systems RAID (0+1) - this is a standard feature of Infortrend RAID controllers. It brings the benefits of RAID 1 (high availability) and RAID 0 (enhanced I/O performance through striping). Simply choose multiple drives (more than two) to compose a RAID 1 logical drive, and RAID (0+1) will be automatically implemented. RAID (1+0) or RAID 10 - a logical volume is a multi-level RAID implementation by its own rights. A logical volume is a logical composition which stripes data across several logical drives (the RAID 0 method). A logical volume with several RAID 1 members can be considered as a RAID (1+0), or RAID 10 volume. RAID (3+0) or RAID 30 - a logical volume with several RAID 3 members. A logical volume with several RAID 3 members can be considered as a RAID (3+0), or RAID 53 as defined in "The RAID Book" (from The RAID Advisory Board). RAID (5+0) or RAID 50 - a logical volume with several RAID 5 members. Functional Description 1-17
Chapter 2 RAID Planning This chapter summarizes the RAID configuration procedures and provides some useful tools for first-time configuration: 2.1 Considerations things you should know before setting up the array 2.2 Configuring the Array the basic configuration procedure 2.3 Operation Theory a brief introduction to data bus and system drive mapping 2.4 Tunable Parameters a useful tool that gives you a glimpse of important parameters 2.1 Considerations After you understand the basic ideas behind RAID levels, you may still be wondering how to begin. Here are the answers to some questions that may help you through the decision making process. 1. How many physical drives do you have? When initially creating the drive groups, you should know how many drives you have in your RAID system and in the JBOD attached to the RAID controlling unit. 2. How many drives on each drive channel? Optimal system planning is always a compromise between pros and cons. As a general rule, the number of drives you should connect on each channel equals the data bus bandwidth divided by the maximum transfer rate you can get from each of your hard drives. Knowing the mechanical performance of your hard drives can also help to determine how many drives to connect over a drive channel. Always use fast and large drives of the same capacity for your disk array. A logical drive composed of an adequate number RAID Planning 2-1
