  • 42. Virtual Partitioning Manager● Purpose ● Dedicate/isolate specific resources to an application or customer ● Disk, Data Cache, I/O ● Data cache allocated in 4GB increments ● Facilitates dedicating resources to several applications or internal/external customers in a SE 9985 or SE 9990. ● This is consolidation in context of this software package. ● While flexible enough to change resource over time, in practice, partitions are not expected to be changed frequently.

  • 45. Universal Replicator (UR)● Conceptually: TrueCopy plus more capability: ● Disk Journaling ● In case of WAN-link failure, data is written to disk, and copy suspension and recovery is avoided ● Need to plan for space to accommodate expected outtage. Threshholds are settable ● Remote site polls primary site SE 9990/85to pull data off the production site, decreasing cycles consumed on at production site. ● UR is asynch; combine with TrueCopy Synch for data currency● Use only with SE 9985 and SE 9990. Sun Confidential: Internal Only 45
  • 46. Universal Replicator (UR) -Universal Replictor is more stable than TrueCopy Asynch (TCA) in addressing link issues. 26% of issue are link related:HDS/TRC analysis 04Q/2004 - Engineering tests suggest UR help manage expensive, limited, and unreliable links - TCA could not maintain Remote Copy due to 45 seconds Link down - UR could provide reliable Remote Copy during 5 minutes Link downTCA starts host I/O throttle Universal Replicator maintains Remote Copyto reduce input to cache over cache 30% during link down until JNL fullResponse time(ms) Link down Link up 5 minutes UR guarantees data consistency during Link down TC Async TCA Suspend (Cannot maintain remote copy after Suspend After Suspend, TCA receives host I/O) 45 sec UR Time Sun Confidential: Internal Only 46
  • 47. Example: Universal Replicator● Before ● WAN-link fails; transactions overflow cache ● Suspend copy and initiate re-synch operations● After (e.g with Universal Replicator) ● WAN-link fails and transactions are written to disk ● WAN-link is restored, copy operation resumes, no copy suspend, no re-synch operation ● Pull technology polls central to transmit data according to bandwidth capacity ● Customer can by smaller pipe● Benefits: Lower WAN costs and reduced operational disruptions Sun Confidential: Internal Only 47
  • 48. Tiered Storage Manager Details● “Volume Migrator” is the underlying engine● Search capability enables collection of application data to be grouped and migrated● Example: Condition is: RAIDLevel IS RAID5 AND DriveType IS FC-AL AND ArrayGroup IS NOT 2-1● Groups of volumes can be migrated at the same time (migration groups)● A group of volumes can serve as migration targets (storage tiers) Sun Confidential: Internal Only 48
  • 49. Example Tiered Storage Manager● Customer topology ● SE9900 with SE3511 and EMC● Use Tiered Storage Manager (TSM) to select several volumes and migrate them to specific target volumes● Result: automated movement of data according to its value ● Reduced DLM costs Sun Confidential: Internal Only 49
  • 50. Continuity Example Sun Confidential: Internal Only 50
  • 51. ShadowImage In-System Replication Up to 9 Full Duplicate Copies of Any Data Volume Secondary Volume Secondary Volume Secondary Secondary VolumeNon-stop VolumeProduction Secondary Primary Secondary Volume Volume Volume Secondary Secondary Volume Volume Secondary Volume 9 Copies Total Open Systems Sun Confidential: Internal Only 51
  • 52. SE 9900 ShadowImage Operations● R/W operations continue during creation of S-Vol. ● R/W operations buffered in data cache● Pair status monitored to ensure completion of copy operations● Meta data about changed/new data kept in differential bitmap in shared memory to support resynch operations● R/W operations may also be performed on S-Vols. S- Vols need not be fully populated before other copy software begin operations on S-Vol. Writes can be held in cache while other copy operations are executed against the S-Vol.● TrueCopy Remote Replication and Universal Replicator use SI P-vol. Sun Confidential: Internal Only 52
  • 53. Copy On Write● Copies Changes only ● Create Primary Volume (P-Vol) from the Production DB. ● Create a Secondary Volume (S-Vol) from the P-Vol. ● This is a Copy on Write Snapshot Pair● The S-Vol is carved out of a pool of allocated physical storage called a “Pool-Vol” ● Pool-Vol can dynamically grow; thresholds settable● Cannot snap off of a snap (e.g. No S-Vol to S-Vol) ● A snap can be taken off of a P-Vol ● TrueCopy (TC) and SI can operate off of a P-Vol. ● Use for write oriented applications: 60% W, 40% R is rough limit. Sun Confidential: Internal Only 53
  • 54. Sun Confidential: Internal Only 54
  • 55. TrueCopy to Remote DR site.● S-Vol copied by TC to Remote DR site may be re-mounted as a P-Vol. ● COW Snaps can be taken off this P-Vol ● Tape would use use a SI S-Vol created from P-Vol in order to avoid write contention.● Updates to remote DR site occur realtime, assuming cache write through Sun Confidential: Internal Only 55
  • 56. SnapBack Operations● Snapback ● Can now snapback to any version ● Do not have to delete later versions Sun Confidential: Internal Only 56
  • 57. Summary● The SE 9985 and SE 9990 represent the highest levels of: ● Availability ● Managability ● Scalability ● Connectivity ● Performance Sun Confidential: Internal Only 57
