4. This option is available in the drive channel configuration menus of Fibre SATA based subsystems Default is AUTO and should work fine with most drives Changing this setting is not recommended unless some particular bus signal issues occur All SATA ATA based system connects only one drive per SATA ATA channel This helps to avoid single drive failure from affecting other drives The maximum mechanical performance of today s drives can reach around 30MB sec sustained read This is still far below the bandwidth of a drive channel bus Setting the SATA ATA bus speed to a lower value can get around some problems but will not become a bottleneck to system performance Mind that the SATA ATA speed is the maximum transfer rate of SATA ATA bus in that mode It does not mean the drive can actually carry out that amount of sustained read write performance For the performance of each drive model please refer to the documentation provided by drive manufacturer 115 Galaxy 16 User Guide 8 13 System Functions Cache status Main Pen Quick instslla ion wiew and it Logical crives vlew and edit Lagical Yolumes wlew and edit Host luns wlew and edit sesl Drives and edit Ges charnels wiew and edit ConF ae parame mrs view and edit rel devices Y v Mute beeper Pazzunrd Reset control l r contrs ler folntenarce

Drives j Volume o o rer Physical Drives Physical Drives Logical Drive Figure 4 15 Logical Volume O S A logical volume is a combination of RAID 0 Striping and other RAID levels Data written to a logical volume is first broken into smaller data segments and striped across different logical drives in a logical volume A logical volume can be divided into a maximum of eight partitions During normal operation the host sees a non partitioned logical volume or a partition of a partitioned logical volume as one single physical drive The benefits of using logical volumes include Expand the MTBF mean time between failure by using more redundancy drives spare drives Decrease the time to rebuild and reduce the chance of data loss caused by multiple drive failures happening at the same time Avoid the disastrous loss of data caused by channel bus failure with proper drive deployment Cost efficiency Functional Description As shown in Figure 4 16 numerous drives can be included in a logical drive and one of them is used for redundancy By grouping these drives into several logical drives and then into a logical volume chance of failing two drives in a logical unit is greatly reduced Each logical drive can have one or more local spares A failed drive can be immediately replaced by a local

107. Card Figure 11 6 Mapping System Drives IDs e Some operating systems do not read multiple LUNs under single ID As diagrammed above you may have the host channel to present several IDs and map logical configurations to these IDs Each of these IDs is identified as Primary or Secondary As a rule for most operation systems each configuration unit will be mapped to LUNO under each ID A limitation is imposed on the 1Gbit Fibre channel which supports single target ID per host port Two host channels will be necessary for an active active configuration Each host channel presents one active ID Primary or Secondary If one controller should fail the standby ID chip on the counterpart controller will be conducted to continue host s I O requests Note that standby IDs will not be seen by users Firmware will activate the standby ID once it discovers the controller on which the active ID resides has failed Multiple Target IDs are supported on the 2Gbit Fibre controllers meaning an active active configuration can be set with single host port Fault Tolerance What Is a Redundant Controller Configuration Hardware failures can occur A simple parity error may sometimes cause a RAID system to completely hang up Having two controllers working together will guarantee that at least one controller will survive the catastrophes and keep the system working This is the logic behind having the redundant controllers to minimize the chance

122. Theory of Operation the theory behind data bus and system drive mapping Considerations After you understand the basic ideas behind the RAID levels you may still be wondering about how to begin Here are the answers to some questions that may help you through the decision making 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 enclosure or in the JBOD attached to the RAID appliance 2 How many drives on each drive channel The 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 the average of your hard drives Knowing the mechanical performance of your hard drives can help to determine how many drives should be connected over a drive channel Always use drives of the same speed and capacity for your disk array A logical drive composed of an adequate number of larger drives can be more efficient than that of many but smaller drives 3 How many drives would you like to appear to the host computer It must be decided what capacity will be included in a logical configuration of drives A logical configuration of drives will appear to the host as a single capacity volume 61 Galaxy 16m User Guide 62 A logical drive composed of fewer but larger drives can be more efficient than that of
