13. Mailbox Server Storage Design (cont.) ● RAID Controller configuration ● DAS-based RAID controllers with a 256- MB battery-backed cache ● SAN-based controllers with a battery- backed cache of 16 GB ● Logical Storage Configuration

14. ● Mailbox I servers ● Designed during Beta 1 ● Use DAS-based solution ● Move from LFF to SFF disks ● Mailbox II and III servers ● Use SAN-based solution ● Designed during Beta 2 External Storage Configuration

15. ● Universal Storage Building Blocks ● Consists of two storage enclosures and supports up to 1,200 users ● Mailbox I and II servers use two building blocks ● Mailbox III server types use three building blocks based on number of users External Storage Configuration (cont.)

16. ● Mailbox Databases, and Storage Groups ● Data distributed across seven mailbox databases per drive ● Fault Tolerance and Reliability ● Storage enclosures connected to different controller ports per building block External Storage Configuration (cont.) Server Design RAID Controller Port 1 RAID Controller Port 2 Comments Mailbox I and IIA, CB, DThe Mailbox I and II designs use two USBBs with the enclosure pairs A-B and C-D. Mailbox IIIA, C, EB, D, FThe Mailbox III design uses three USBBs with the enclosure pairs A-B, C-D, and E-F.

17. Exchange Server Backup Solution ● With Exchange Server 2003 on the 32-bit platform ● 1.2 terabytes per backup cycle ● Full restore can take up to 24 hours ● Three redundancy levels with Exchange Server 2007 on 64-bit platform ● Mailbox store ● Hub server transport dumpster ● Online database backups

18. Mailbox Store Backup Features ● Mailbox servers in CCR clusters ● Two-node Majority Node Set (MNS) server clusters with file share witness ● Requires a single mailbox store database per storage group ● All cluster nodes use DAS and separate storage subsystems

19. Transport Dumpster Features ● Hub Transport servers retain a copy of all messages delivered to clustered mailbox servers ● Messages remain for a specified period in transport dumpster queue ● Queued messages available for redelivery ● Necessary if a failover occurs to a passive node before CCR has copied the most recent messages ● Need to enable transport dumpster feature through set-TransportConfig PowerShell command ● Transport dumpster uses additional disk space

20. Online Database Backups ● Daily incremental online backups for redundancy and weekly full backups ● Separate RAID controller and RAID5 array backs up each active node in the CCR clusters ● Streaming disk-to-disk backup with command-line scripts for backup through NTBackup.exe Storage groupMonTueWedThuFriSatSun SG 1FullInc SG 2IncFullInc SG 3Inc FullInc SG 4Inc FullInc SG 5Inc FullInc SG 6Inc FullInc SG 7Inc Full

21. The Results ● Lower storage costs ● Eliminate tape backups ● Increased employee productivity ● Compliance with legal and regulatory requirements ● Improved messaging protection ● Establishment of foundation for new SLAs ● Simplified operational tasks ● Demonstrated confidence in the product ● Demonstrated confidence in the product Benefits
