Any spare drives? (Swap Drive Rebuild / Spare Drive Rebuild) Spare drives allow for the unattended rebuilding of a failed drive, heightening the degree of fault tolerance. If there is no spare drive, data rebuild has to be manually initiated by replacing a failed drive with a healthy one. As is often ignored, a spare drive (whether dedicated or global) must have a capacity no smaller than the members of a logical drive. 9. Limitations? Firmware 3.31 and above support 64-bit LBA. A maximum of 64TB capacity can be included in single logical drive. Up to 128 members can be included in each logical drive. Extreme array sizes can cause operational problems with system backup and should be avoided. <strong>Infortrend</strong>
2.2 Configuring the Array 2.2.1 Starting a RAID System Here is a flowchart illustrating basic steps to be taken when configuring a RAID system. Hardware installation should be completed before any <strong>configuration</strong> takes place. Figure 2 - 2 Array Configuration Process Drives must be configured and the controller properly initialized before a host computer can access the storage capacity. 1. Use the LCD panel, terminal program, or the RAIDWatch manager to start configuring your array. 2. When powered on, the controller scans all the hard drives that are connected through the drive channels. If a hard drive is connected after the controller completes initialization, use the "Scan SCSI Drive" function to let the controller recognize its presence. 3. Optimize the controller's parameters for your applications. 4. Configure one or more logical drives to contain your hard drives based on the desired RAID level, and/or partition the logical drive or logical volume into one or several partitions.
