  1. EMC makes Exchange 2010 Better!! Optimizing Exchange 2010 while driving out cost and complexity.

  2. Microsoft adds new Features & Functions Exchange 2010 has evolved, even since RTM… • Reduce TCO by • Allowing use of SATA drives, JBOD, DAS • Increase mailbox sizes, increase speed, facilitate Legal Hold • Eliminate need for third-party journaling, archiving, & search • Enable Cloud/Private Cloud • Support for Virtualization • Open support for SAN/iSCSI/FCoE… • Open reality check on JBOD usage • Support for more DAG-Replication scenarios

  3. What are your concerns as you move to Exchange 2010? • Server virtualization • Microsoft used to discourage it, but it’s widely successful • I love VMware, should I like Hyper-V too? • Storage – DAS vsArray • I need 2TB to finish the migration; can I add more space later? • What’s wrong with my SAN?! • High Availability • How many copies should I have?! • How many servers should I deploy • Backup and Recovery — system, databases, items • If I have three copies, do I need to back it up?! • What if I use NearPoint? How does that affect my HA,BR,DR plans • Disaster Recovery • Oy. • Can I have one remote copy and make it part of the Active DAG? • Can I have Active databases at both sites?

  4. EMC makes Exchange 2010 Better! How can EMC drive costs out while adding… • Control • I want to control my own servers, storage, network, and OS’s • I don’t care how many servers I need, but I need to patch them… • Capacity • Microsoft tells me to allocate for three years, what if I’m wrong?! • Why do I need SIX bloody times the space of my 2003 SCC implementation?! • Flexibility • Can I add servers to the DAG as I add users, capacity? • Can I take servers away? Can I add servers to the DR site to handle load? • Performance • I don’t need to worry about performance any more… RIGHT?! • My boss will let me overbuild this, but how much is too much, what’s enough? • Functionality • Boy I wish I could provide Legal Search to our Legal Counsel • How do I handle rolling corruption? That’s not going to happen RIGHT?!

  5. Exchange DAG Overview AD site: Dallas All clients connect via CAS servers Client Access Server DB1 Client DB3 Mailbox Server 6 AD site: San Jose DB5 Client Access Server Easy to stretch across sites Failover managed within Exchange Mailbox Server 1 Mailbox Server 2 Mailbox Server 3 Mailbox Server 4 Mailbox Server 5 Database Availability Group DB1 DB1 DB1 DB4 DB2 DB5 DB3 DB2 DB5 DB3 DB4 DB1 Database centric failover DB3 DB1 DB2 DB5 DB4 2009 - Exchange DAG Overview Microsoft Confidential -- Ross Smith IV

  6. Four-pronged ApproachVisionary Thought Leadership redefines lowest possible TCO

Flash Flash Fibre Channel Fibre Channel SATA SATA Exchange 2010 – the EMC Way Exchange 2010 – the EMC Way Database Availability Group Optimized – Infrastructure, WAN, Storage, Backup EMC’s Unified, Lower Cost, More Capable Solution for Exchange 2010 • Fewer • Physical Servers, • OS & Application licenses, • OS & Application installations • Database copies • Increased • Data protection • Item-level recovery • Mailbox sizes • Simplified • Day-to-day management • Patch management • Site-to-site failover • Lower • Cost of initial deployment • Cost of growth • Cost of management Virtual LUN Virtual LUN RP-Journal RP-Journal

  8. Store: Exchange 2010 Brings: • Contiguous Mailboxes • Removal of SIS • Concatenated Mailboxes • Compression of HTML • Background Database Maintenance (BDM) • 64KB and 256KB disk operations • 100MB Checkpoint Cache

  9. E2K10: Store Table Architecture Per Database Per Folder E2007 Secondary Indexes used for Views Per Mailbox Per Database Per View E2010 New Store Schema = no more single instance storage within a DB Source: Matt Gossage, Microsoft Sr. Program Manager

  10. E2K10: Logical Contiguity Mailbox E2007 Many, small size, IOs Random E2010 Sequential Fewer, large size, IOs Source: Matt Gossage, Microsoft Sr. Program Manager

  11. Store: Exchange 2010 Brings: EMC makes Exchange Better: Capacity as needed Higher density storage Cache pre-fetching Automated storage tiering Storage Processors built for high bandwidth operations Storage Pools ideally suited for consolidated queue operations • Contiguous Mailboxes • Removal of SIS • Concatenated Mailboxes • Compression of HTML • Background Database Maintenance (BDM) • 64KB and 256KB disk operations • 100MB Checkpoint Cache

  12. Store: Microsoft “Best Practices” EMC makes Exchange Better Allocate storage to complete migration – add storage based on trends Let the array Protect the data: Store one copy of mail, Use disks for storing more mail, not copying the mail No “BINGO Sheet talent” required Replicate mail once: Optimize WAN utilization by using 1/3rd the bandwidth Optimize use of remote site for HA, DR, and BC Optimize replication by avoiding reseeds • Pre-allocate all storage on “day one” and add best guess for growth • Store 3 copies of mailboxes, reseed often – develop operational excellence • Replicate mail at least twice over the WAN • Reseed after remote site backup

  13. Store: Microsoft allocation method EMC makes Exchange Better Measure mail in source platform, calculate SIS ratio Design storage to absorb migrated mail Collect trend data, plan for storage increases • Measure mail from source platform – based on Profiler • Calculate required storage for concatenated mailboxes • Guess growth requirements 1.7X Add 0.5X in 1yr

  14. Store: Storage Pools • Optimize disk usage:mix different drive types (Drive mix user selected) • Recommended Ratio: SSD:SAS:SATA ~ 5%:20%:75% • Protect with RAID5, RAID6, RAID1/0, or even RAID 0! • Storage Pools are expanded dynamically • Add SSDs for more performance • Add SATA for more capacity • Thick or Thin Provision • LUNs are expandable • LUNs can be migrated on-the-fly

  15. Store: FAST VP: Automated Performance Tuning for Exchange Databases Traditional FAST (Volume/LUN level) FAST VP (Sub-LUN) • No need for • Policies, • Personal Archive Folders, • Moving users from dB to dB • Add storage based on • Capacity needs • Performance needs • DONE! Flash–10% NL-SAS–90% Flash–10% Fibre Channel–40% SATA–50%

  16. Store: EMC Storage Integrator (ESI) Providing Simplified Management for Windows Hosts • Storage provisioning for Windows Servers • Application-aware storage provisioning • Windows MMC based • Agent-less architecture • Supports VMAX, VNX, VNXe, CX4, and NS series • Block and file support Easy-to-use MMC Snap-ins for the Server/Application Admin

  17. Store: DEMO View your Exchange storage from the tools you know

  18. Protect: Exchange 2010 Brings: • CRC-level checking in three-copy DAG via BDM • DAG-Replication creates “secondary failure domains” • Store Schema, DAG-R and BDM allows use of “cheap storage”

  19. Protect: Exchange 2010 “outage-mitigation technologies”: Secondary dB copies updated via Log Shipping Data commit-based replication to avoid rolling corruption Lagged copy option allows recovery to previous points-in-time • Background Database Maintenance • 256KB blocks continuously scanned and inspected for “page tears” • Page-level reordering to continuously defrag dB • Insertion of additional white-space to enhance dB efficiency, sequentially

  20. Protect: Exchange 2010 Brings: EMC makes Exchange Better: Integrated block-level CRC offloads all data integrity checks Proactive hot sparing allows designers to cancel-out RAID-rebuilds Rebuild logging prevents *over events by keeping volumes online UltraPoint • CRC-level checking in three-copy DAG via BDM • DAG-Replication creates “secondary failure domains” • Store Schema, DAG-R and BDM allows use of “cheep storage”

  21. What the heck is a “failure domain”?! True or False: True or False: Two copies of a SQL database replicated synchronously Three copies of Exchange dBs replicated with DAG-Replication A single Exchange dB and an archive with 75% of the mail “stubbed” from the dB …a logical/physical boundary between systems • Two copies of a SQL database linked by log-shipping • Two copies of Exchange dBs replicated with HW VSS • A single Exchange dB and an indexed Journal of all it’s mail FALSE! FALSE! …sorry, nope… TRUE! TRUE, but..! Not even close!
