Presentation Transcript

  1. member of Erste Group 80 people (Croatian subsidiary) 250 people (Together with IT Dev part of ErsteBank) IT service provider for ErsteBank Group entities 3 Datacenters in Croatia(Zagreb, Bjelovar, Rijeka) Microsoft technologies (AD, Exchange, SQL, Lync, System Center, TMG, SharePoint, TeamSystem, File Servers, Failover Clustering, DFS, Hyper-V, etc...) 500 servers (90% virtualized)

  2. Hyper-V, Guest Clustering, Deduplication

  3. Support for Virtual Fibre Channel Adapters Supported HBA and SAN NPIV supportrequired Live Migration of the VM GuestCluster MPIO ontheguest Notsupported Bootfrom SAN Snapshots Host basedbackupsusing VSS Live Storage Migration of plain data onthe SAN

  4. Virtual Fiber Channel architecture Up to 4 VFC adapters Guest MPIO Eachadapterisassociatedwith a virtual SAN DSM Guest MPIO DSM SAN Switch Fabric • Each adapter connects with one or two WWNN\WWPN address pairs • HA VMs require two to support mobility scenarios in the cluster

  5. Virtual Fibre Channel Adapters NPIV settings Eachadapterisassociatedwith a virtual SAN Eachadapterconnectswithoneortwo WWNN\WWNP addresspairs HA VMsrequiretwoformobilitysupport in cluster

  6. Guest Clustering using FC storage access FC SAN LUN • VMs should use WS2008, WS 2008 R2 or WS 2012 • NPIV Support required • Up to 4 HBAs inside Guests • Multiple SANs access • MPIO on Host and Guest can coexist • Live Migration supported • WWN Pairs should be assigned to the VMs • Hyper-V alternates between Set A and Set B on LMs

  7. The fibre channel adapter is certified for Windows Server 2012 Check with your fibre channel adapter vendor that: • You have the latest firmware and drivers for the adapter • #1 issue we’re seeing so far

  8. NPIV is enable on the Fibre Channel HBA and Verify that you have enabled NPIV on the storage fabric meaning: • NPIV is enabled on the Fibre Channel Switch port • Configure WWPN/WWNN as stated in the TechNet article HERE?

  9. Fibrechannel also offers a similar sounding feature called NPV Finally: • Hyper-V doesn’t use NPV • Hyper-V requires NPIV

  10. Demo #1 • Virtual FC adapter • SAN Switch, WWN, Zoning • LUN mounting • Clustering • Live Migration while copying data to/from cluster

  11. Common Data Optimization Techniques

  12. Pre Deduplication This is what the files look like before deduplication

  13. Identify the Chunks that are Identical Unnamed Data Stream Metadata Attributes A B C M N O Metadata Unnamed Data Stream Attributes A B C X Y Z

  14. Move Data Chunks into the Chunk Store Unnamed Data Stream Metadata Attributes Metadata Unnamed Data Stream A B C M N O Attributes A B C X Y Z

  15. Move Data Chunks into the Chunk Store Unnamed Data Stream Metadata Metadata Attributes Attributes Sparse Reparse Point Metadata Unnamed Data Stream Metadata A B C M N O Attributes Attributes A B C Sparse Reparse Point X Y Z

  16. Post Deduplication The data streams have been moved to a new structure called the chunk store. In place of the data stream, a reparse point is created that points to the chunk store.In addition, the stream is marked as sparse to indicate that the stream is segmented.

  17. The Chunk Store The Dedup files, like VSS files, are stored in each volume's respective 'System Volume Information' directory. This includes logs, settings, state information, and the actual Chunk Store.

  18. Quick Glance Dedup Facts

  19. Quick Glance DedupFacts II

  20. Typical Savings

  21. ErsteBank Example #1 • File Cluster, File Share Volumes

  22. ErsteBank Example #2 • General File Share Volume

  23. Garbage Collection and Data Scrubbing • Garbage collection process to clear data chunks that are no longer referenced. This process deleted content to free up additional space. • Data scrubbing checks integratiy and validate the checksum data. • These jobs can be ran manually by running Start-DedupJob–Type Scrubbing and –TypeGarbageCollection.

  24. Demo #2 • Setting Deduplication on File Cluster • Starting Deduplication • Optimization Analysis
