  2. Case study • Customer: Sprint, SBC and AG Edwards • Problem statement • Rapid growth • Large complex environments • High availability is paramount • Multi-platform environments • Budget dollars are hard to come by • Revenue represented • Aprox.5 million in recent revenue on the HP platform

  3. The Value proposition * Creating Operational Efficiencies • Manage more systems and storage in less time and with less resources • Reduce your maintenance windows • Repurpose older storage • Manage multiple tiers of storage more effectively while maintain current SLA’s • Reduce the amount of storage needed in your environment

  10. Problems with LVM • PE_SIZE is set at VG creation. (Default 4MB) • Cannot be changed after creation. • MAX_PE is set at VG creation. (Default 1016 or #PEs on largest disk) • Cannot be changed after creation. • Cannot add larger disk to VG and use all available space on disk. • MAX_PV is set at VG creation. (Default 16) • Cannot be changed after creation. • Must know MAX_PV value when VG is created. • Since these values are fixed at VG creation, the PE-LE map size is fixed also. • To change any of these values, the HP administrator must back up the data, destroy the existing VG, recreate the VG with new values, then restore the data.

  17. Storage Foundation 4.1 (Q3 ‘05) Major New Themes • Share Data Across Platforms • Make it Easier to Allocate Storage • Move Data to the Most Appropriate Storage Device • Improve Performance and Manageability of DMP

  18. Share Data Across Platforms Portable Data Containers Linux Solaris HP-UX AIX • Solaris records the incoming data • HP-UX batch processes the data • AIX loads the data onto a data warehouse • Linux backs up the data Simplifies Serial Processing Enables Easy Data Migration Reduces Vendor Lock-in Eliminates “Double Storage”

  19. Intelligent Storage ProvisioningStorage provisioning can be challenging Storage provisioning without ISP • Mission Critical • High-end storage • 4 column stripe • 3 mirrors (2 offsite) Disk Group • Takes too long • Risk of errors • Inconsistent • Virtually impossible to create storage service levels

  20. New in 4.x Mission Critical Business Priority Snapshot • StorageWorks XP12000 • 3 Mirrors • One Mirror in BLDG A • Two Mirrors in BLDG B • Virtual Array 7410 • 2 Mirrors • One Mirror in BLDG A • One Mirror in BLDG B • Virtual Array 7410 • RAID-5 Intelligent Storage ProvisioningTemplates reduce cost and risk Storage Provisioning Templates • Provisions storage faster • Eliminates configuration errors • Creates company-wide consistency • Simplifies implementation of storage service levels

  21. Quality of Storage Service Storage Today: Problem = All data created “equal” • One class of storage • When storage is consumed: • Delete files • Archive files to tape • Buy more storage 1997 EmployeeReviews CurrentHR Files 2004 Holiday Party Pictures HR DepartmentEVA3000

  22. New in 4.x Quality of Storage ServicePolicy-based tiered storage QoSS Overview • Multiple classes of storage available from one file system • Policy-based, automatic relocation • Transparent to applications VERITAS File System 2004 Holiday Party Pictures CurrentHR Files 1997 EmployeeReviews EVA3000 DS 2120

  23. Quality of Storage ServiceSimple implementation How it Works • Create two or more volumes • Group volumes into a volume set • Create a file system on top of the volume set • Applications and users create files • Set and run relocation policies VERITAS File System EVA3000 DS 2120 No Application Changes Necessary

  24. MENU DMP Management Enhancements • Can Set Policies for Load Balancing • Now Fully Managed from GUI • Detailed Stats • Can Now Specify Which Paths to Scan • Automatically Recognizes Changes in Server Partitions

  25. MENU DMP Performance Enhancements • Several New Load Balancing Algorithms • Balanced path • Round-robin • Minimum queue length • Priority-Based • Adaptive Priority • Concurrent A/P • A/P-C, A/PG-C

  26. MENU Storage Expert • Scans Configuration for Common Errors • Makes Recommendations for Improvement Poor Fault Tolerance Improper Layout Slow Relayout (Configuration Changes) Poor Recovery Time Poor Utilization of Storage Too Many Volumes to be Checked by Hand Configuration Degradation

  27. MENU Major FlashSnap Enhancements • Incremental Volume Level Checkpoints • Similar to File System Checkpoints • Split Mirror Before it is Synchronized • Unlimited Number of Snapshots • Integrated with NetBackup • Can Take and Mount Checkpoints from VEA • Restore an Entire File System to a Point In Time • Create Storage CheckPoints Faster

  28. MENU Instant Snapshots Instant Split of 3rd Mirror Makes Mirror Available BEFORE It Sync’s

  29. & QUESTIONS ANSWERS

  30. VxVM: Physical Allocation VM Disk private region subdisk public region VxVM utilizes variable sized allocation units called subdisks. These structures are defined by an offset into the public region and a length for flexibility in space allocation.

  31. PVRA VGRA The Real View Two views of an LVM disk PVRA/VGRA physical extents HP’s View So why do we care about this?

  32. The LVM ‘Bermuda Triangle’ (1-65535) MAX_PE (Max # of PEs on single PV) (Resolution size of LV) (Max # PVs in VG) PE_SIZE (1-256 MB) MAX_PV (1-255) This is what every HP system administrator must think about when creating a new volume group.
