  1. Required Slide SESSION CODE: UNC306 Going Big! Deploying Large Mailboxes with Microsoft Exchange Server 2010 without Breaking the Bank Kevin St. Clair Sr. Support Engineer Hewlett-Packard

  2. AGENDA • What do large mailboxes give me? • What do I need to consider when deploying large mailboxes? • How do all of the parts fit together in a solid design?

  3. Why large mailboxes?Get PST files under control • User’s PST files at risk on the laptop or desktop • User’s PST files typically not backed up • Recovery from corruption is painful 2006-PST 2007-PST 2010-PST 2008-PST 2009-PST

  4. Why large mailboxes?Add value for users • Search historical data • Don’t recreate work • Reduce time spent managing mailbox

  5. 2010-PST Why large mailboxes?Add value for users • PST files only available on single machine 2010-PST

  6. Why large mailboxes?Adding IT Value • Search across all mailboxes including data that was in a PST • Dumpster 2.0 – searchable as well! • Legal Hold • Use high-capacity drives efficiently

  7. Large mailbox considerationsPresent Environment • Skillset and training of staff • Stability Issues • Pain points

  8. Large mailbox considerationsBusiness Needs • Business requirements, expectations and SLA • Productivity Features – Mailbox moves online • Search historical information

  9. Large mailbox considerations

  10. Large mailbox considerationsDisaster Recovery • Backup & restore methods ~30 seconds 2+ hours – weekly full

  11. Large mailbox considerationsDisaster Recovery • Availability consideration • Continuous availability (DAG)

  12. Large mailbox considerationsDisaster Recovery • Availability consideration • Continuous availability (DAG) • Restoration of service (non-DAG)

  13. Large mailbox designKnow your environment • Strengths and weaknesses • User profile and data quantity = Mailbox data + PST data • Exchange Server 2003 support ending when the next version of Exchange releases

  14. Large mailbox designSelect appropriate options • Business requirements • Storage • Licensing

  15. Large mailbox designBusiness requirements • Service Level Agreements (SLA) • Business requirements • Regulatory compliance • Increase in mail volume for users

  16. Large mailbox designStorage Performance 0.12 IOPS • Balancing act between performance and capacity Capacity 10 GB

  17. Large mailbox designStorage • Performance Drivers • User workload

  18. Large mailbox designStorage • Performance Drivers • User workload • Third party applications – BlackBerry • Desktop Search

  19. Large mailbox designStorage • Exchange Storage changes • Move from random to sequential IO • Larger database page size: • Exchange 2010 has 32 KB page size • Exchange 2007 has 8 KB page size

  20. Large mailbox designStorage • Exchange Storage changes • Reduction in IOPs

  21. Large mailbox designStorage • Performance Drivers • Maintenance • Default is 24x7 • Large block sequential

  22. Large mailbox designStorage • Disks increasing in size • Disk speed has remained unchanged • Largest capacity disks are midline SAS and SATA

  23. Large mailbox designStorage • Database capacity • Message data • Deleted Items • White space • Legal Hold • Performance and capacity overhead Database

  24. Large mailbox designStorage • Two LUNs per database or backup set • RAID Free Space 20% Content Index 10% Database Free Space 20% Transaction Logs

  25. Large mailbox designStorage • One LUN per database • JBOD Free Space 20% Content Index 10% Database Transaction Logs

  26. Large mailbox designStorage • Mount Point Root

  27. Large mailbox designStorage • Types of storage • Internal direct-attached storage (DAS) • External direct-attached storage (DAS) • Storage Area Network (SAN)

  28. Large mailbox designStorage • Storage connectivity • Array controller • Cache • Logical and physical drives • Host Bus Adapter (HBA) • Fibre Channel

  29. Large mailbox designStorage – per spindle • Exchange 2007 • Heavy user profile (20 sent/80 received) • 0.32 IOPS per user • 300 GB – 15K RPM disk (useable 279 GB – 20%) = 223 GB with 150 IOPS • Performance - 150 IOPS / 0.32 IOPS per user = 468 mailboxes per disk • Disk size 223 GB / 468 mailboxes= 476 MBper mailbox

  30. Large mailbox designStorage – per spindle • Exchange 2010 • Heavy user profile (100 sent & received) • 0.12 IOPS per user • 300 GB – 15K RPM disk (useable 279 GB – 20%) = 223 GB with 150 IOPS • Performance - 150 IOPS / 0.12 IOPS per user = 1,250 mailboxes per disk • Disk size - 223 GB / 1,250 mailboxes= 178 MB per mailbox

  31. Large mailbox designStorage – per spindle • Exchange 2010 • Heavy user profile (100 sent & received) • 0.12 IOPS per user • 2 TB – 7,200 RPM disk (useable 1.818 TB – 20%) = 1.454 TB with 50 IOPS • Performance - 50 IOPS / 0.12 IOPS per user = 416 mailboxes per disk • Disk size – 1,454 TB / 416 mailboxes= 3.50 GB per mailbox

  32. Large mailbox designActual Design – Large Enterprise Company • 150,000 Mailboxes • Current – 150 MB mailbox size • 200 Messages sent and received • Mailbox sizes discussed • 1 GB, 5 GB, 10 GB and 12 GB • SAN and DAS both considered • Exchange team wants to control all aspects of Exchange • Cost • Reliability

  33. Large mailbox designActual Design – Large Enterprise Company • Exchange high-availability (DAG) • Two copies in primary site • Site resilience – two copies in DR site • 12 GB Mailbox size • 8,192 – 2 TB drives (JBOD) • 36,000 – 600 GB drives (RAID5) • 19,344 – 2 TB drives (RAID10)

  34. Large mailbox designActual Design – Large Enterprise Company • Exchange high-availability (DAG) • Two copies in primary site • Site resilience – two copies in DR site • Reduced to 4 GB Mailbox size • 5,600 – 2 TB drives (RAID10)

  35. Large mailbox designActual Design – Large Enterprise Company • Exchange high-availability (DAG) • Two copies in primary site (RAID10) • Site resilience – two copies in DR site • Copy 1 – Site Resiliency (RAID10) • Copy 2 – 14-day Lagged copy (RAID10) • Exchange Native Data Availability
