3. For example using simple striping as shown in Figure 3 failure of any hard drive leads to failure of all logical drives in the same array and hence to data loss To protect against data loss from hard drive failure storage systems should be configured with fault tolerance HP recommends adhering to RAID 5 configurations The table below summarizes the important features of the different kinds of RAID supported by the Smart Array controllers The decision chart in the following table can help determine which option is best for different situations Table 2 Summary of RAID methods RAID 0 Strip RAID 5 Distrib ing no foul D HOMI ied Date RAID 6 ADG roring e tolerance Guarding Maximum number of hard N A drives Storage system dependent Tolerant of single hard Yes Yes drive failure If the failed drives are not mirrored to each other Tolerant of multiple simul taneous hard drive fail ures Yes two drives can fail Online spares Further protection against data loss can be achieved by assigning an online spare or hot spare to any configuration except RAID O This hard drive contains no data and is contained within the same storage subsystem as the other drives in the array When a hard drive in the array fails the controller can then automatically rebuild information that was originally on the failed drive onto the online spare This quickly restores the system to full RAID level fault tolerance

P1 P3 can be logically combined into one or more logical units L1 called arrays When this is done the read write heads of all the constituent physical drives are active simultaneously dramatically reducing the overall time required for data transfer EY NOTE Depending on the storage system model array configuration may not be possible or necessary BW qQ EM EZ E B E E E P1 P2 P3 gl0042 Figure 2 Configuring arrays from physical drives Because the read write heads are simultaneously active the same amount of data is written to each drive during any given time interval Each unit of data is termed a block The blocks form a set of data stripes over all the hard drives in an array as shown in Figure 3 1 163 Fer us 9 B12 gl0043 Figure 3 RAID O data striping S1 S4 of data blocks B1 B12 For data in the array to be readable the data block sequence within each stripe must be the same This sequencing process is performed by the array controller which sends the data blocks to the drive write heads in the correct order A natural consequence of the striping process is that each hard drive in a given array contains the same number of data blocks EY NOTE If one hard drive has a larger capacity than other hard drives in the same array the extra capacity is wasted because it cannot be used by the array X1800sb and X3800sb Network Storage Blade 27 Fault tolerance Drive failure although rare is potentially catastrophic
13. Scheduling defragmentation Defragmentation is the process of analyzing local volumes and consolidating fragmented files and folders so that each occupies a single contiguous space on the volume This improves file system performance Because defragmentation consolidates files and folders it also consolidates the free space on a volume This reduces the likelihood that new files will be fragmented Defragmentation for a volume can be scheduled to occur automatically at convenient times Defragmentation can also be done once or on a recurring basis EY NOTE Scheduling defragmentation to run no later than a specific time prevents the defragmentation process from running later than that time If the defragmentation process is running when the time is reached the process is stopped This setting is useful to ensure that the defragmentation process ends before the demand for server access is likely to increase If defragmenting volumes on which shadow copies are enabled use a cluster or allocation unit size of 16 KB or larger during the format Otherwise defragmentation registers as a change by the Shadow Copy process This increase in the number of changes forces Shadow Copy to delete snapshots as the limit for the cache file is reached A CAUTION Allocation unit size cannot be altered without reformatting the drive Data on a reformatted drive cannot be recovered For more information about disk defragmentation read the onlin
