8、equences of data are analyzed inline by the 3PAR ASIC in 16kB chunks. Chunks of zeroes are not written to the backend, repeating chunks of same data can be deduplicated, other chunks can be compressed.

18、Linux space reclamation Automatic if the mounted file system supports periodic (online) discard i.e. it is mounted with “discard” option. (e.g. Red Hat 6.x ext4, SLES 11 SP2 Btrfs)For example in /etc/fstab:/dev/vgappP01/lvappP01 /app ext4 defaults,discard 2 2orUse batch discard via command fstrim(8)
19、.This approach is implemented via FITRIM ioctlThe file system itself has to support this ioctlAt this point ext4, ext3, xfs, btrfs and ocfs2 support itFor example:# fstrim v /myfs11Allocation units and alignmentImportant things to consider when implementing ADRThe granularity of 3PAR deduplication i
20、s 16 KiB and therefore the dedup efficiency is best when the blocks written are aligned to this granularityFor hosts that use file systems with tunable allocation units consider setting the allocation unit to 16 KiB or a multiple of 16 KiBFor Microsoft Windows the NTFS default allocation unit size i

MS Article ID: 140365 /kb/140365?wa=wsignin1.0 Set the value to16kB or higher when formatting the NTFS volume; find the procedure here:/en-us/kb/2272294 Linux hosts using Btrfs, EXT4 and XFS file systems require no tuning EXT3 file systems align to 4 KiB boundaries and
22、 cannot be tuned; for maximum dedup efficiency migrate to EXT4 For applications that have tunable block sizes consider to setting the block size to 16 KiB or a multiple of 16 KiB12For more info also see the 3PAR Adaptive Data Reduction whitepaper 3PAR Optimization and Tuning Dynamic OptimizationAdap
