22. VERITAS File System

23. What is VERITAS File System? High Performance, Quick Recovery, Journaled File System • Scalable performance • On-line Management and reconfiguration • Maintains data integrity • Common across multiple platforms

24. Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block Disk Block VERITAS File System Inode Disk Block Disk Block Extent Addresses Disk Block Disk Block Direct Address 0 / Length Direct Address 1 / Length Direct Address 2 / Length Direct Address 3 / Length Direct Address 4 / Length Direct Address 5 / Length Direct Address 6 / Length Direct Address 7 / Length Direct Address 8 / Length Direct Address 9 / Length Single Indirect Block Double Indirect Block PerformanceExtent-based Allocation Block-Based Allocation: Spaced allocated 1 block at a time causing fragmentation and hindering performance • VxFS Extent-Based Allocation:Groups multiple blocks into large writes • Faster than block-at-a-time based operations. • Metadata overhead is reduced • Less overhead is necessary with sequential reads

25. Performance Direct I/O • For large FS writes, it is much faster to write directly to the disk • Direct I/O skips the FS cache • BUT, for smaller writes, Direct I/O is slower! • We developed... Discovered Direct I/O • DDI/O looks at the size of each write & gets the best performance from each I/O model Example: • If write is <=256KB, uses the FS cache • If write is > 256KB, uses Direct I/O

26. Journaling File System • Logs file system changes before they are made • Reduces fsck times after a crash from hours to just a few minutes • Parallel fscks – ability to run fscks in parallel at boot time increases availability whenever running multiple file systems on a single host • Maintains Data integrity • Critical for HA environments

27. VERITAS FlashSnap

28. Benefits of FlashSnap • Increase revenue • Simplify environment maintenance • Simplified data warehousing • Simplified application testing • Simplify batch processing • Cost savings

29. VERITAS FlashSnap Option • Point in time copy of data used on-host or off-host • Supports multiple copies of data • Enables off-host analysis and reporting • Fast Resynchronization of Volume Snapshots • Storage Checkpoints • Hardware independent

30. Dynamic Group Split and Join • Feature of FlashSnap • Allows split of a dynamic disk group • Allows 2 dynamic disk groups to be joined • Enables easy re-organization of data • Enables off-host processing

31. Off-Host Processing • Why ? • Reduce the load on the production host • A more consistent I/O pattern for tuning • Operations • Backup • Reporting • Decision Support • Training/Testing • CRM • More….

41. Summary

42. Business Benefits • Lower hardware costs • Maximization of current hardware resources • Hardware Independence • Greater IT productivity • Simplified administration of heterogeneous environments • Proactive management of applications • Increased application ROI • Improved throughput • Increased uptime “on-line everything”

43. Lower Hardware Costs • FACT:Less than 50% of UNIX/Windows disk is utilized • Solution:VERITAS Storage Foundation solutions allow dynamic (re)sizing and logical space allocation • Example: • VxVM “logical” pools across heterogeneous storage subsystems • VxFS extent based file allocation lessens fragmentation to increase performance

44. Lower Hardware Costs • FACT:Homogeneous solutions “trap” enterprises into expensive, proprietary architectures • Solution:VERITAS Storage Foundation solutions provide a consistent approach to heterogeneous environments – the net/net equates to flexibility of choice • Example: • VxFS Storage Checkpoints vs. EMC TimeFinder • VxFS dynamic write optimization vs. NetApp

45. Greater IT Productivity • FACT:Most System and Database administrators spend an increasing amount of time managing an environment growing in complexity • Solution:VERITAS Storage Foundation solutions provide efficiencies by automating manual tasks • Example: • Dynamic VxVM and VxFS sizing • VxVM “on the fly” performance tuning via online subdisk move

46. Greater IT Productivity • FACT:It costs more to manage 10 GB of disk than it does to purchase it • Solution:VERITAS Storage Foundation solutions can provide the benefits of “proprietary commodity” systems without the associated costs • Example: • VxVM FastResync vs. EMC TimeFinder (BCVs) • VxVM DMP vs. PowerPath

47. Increased Application ROI • FACT:Planned downtime and un-planned downtime affect application availability – which equates to lost revenue • Solution:VERITAS Storage Foundation solutions decrease the need for “planned downtime” • Example: • VxVM dynamic RAID reconfiguration (vs. an EMC service call, or copy of the file to new storage) • VxFS online file expansion & defragmentation

48. Increased Application ROI • FACT:70 – 80% of database applications are allocated on RAW partitions and basic file systems • Solution:VERITAS Storage Foundation solutions provide “RAW” performance combined with granular control and logical management • Example: • Quick I/O and ODM for Oracle8i/9i • VxFS/VxVM policy based growth – notifications and automated growth through VxDBA
