23/97


What happened to routing groups?Active Directory sites replace routing groups

Site links replace routing group connectors

Hub servers in same site dont exchange messages

Hub servers send/receive messages between sites

Mailbox servers submit messages to any Hub servers in same site

All mail is routed through a Hub server

All mail routing is direct relay

Deterministic routing

Automatic configurationHubs automatically load-balance


24/97


Mail FlowDirect Relay and Back-Off

- Exchange 2007 attempts to relay directly to destination site (unless a hub site

is defined)

- Exchange 2007 tries all Hub servers in destination site

- If direct connect fails, it queues to the closest point of failure

- Binary Back-Off

Delayed fan-out

- Bifurcate at the closest site to destination

- Reduces the amount of network traffic, through optimized fan-out process- Cannot be disabled

Monitoring Online Database DefragmentationCommon questions

- When online defragmentation was last run?

- How long it took to complete online defragmentation?

- What online defragmentation did when it ran?

Extended information for Event 703 allows you to more easily monitoronline defragmentation pass completions

Two extended Extensible Storage Engine (ESE) performance countersfor monitoring the effectiveness and efficiency of online databasedefragmentation

Event Category: Online DefragmentationEvent ID:703

Description:

MSExchangeIS (19052) SG05: Online defragmentation has completed the

resumed pass on database 'e:\MDB05\database5.edb', freeing 42794 pages.

This pass started on 6/16/2007 and ran for a total of 124919 seconds,

requiring 7 invocations over 4 days. Since the database was created it has

been fully defragmented 14 times over 73 days.

Database Management

Monitoring Online Database DefragmentationHow to manage the online defragmentation window?

- Divide the average Online Defrag Pages Read by the average Online

Defrag Pages Freed

If the read-to-freed ratio is greater than 100:1, the online defragmentation

window can be reduced If the read-to-freed ratio is less than 50:1, the online defragmentation

window should be increased

Online Maintenance Database ScanningWhen enabled

- Check summing and page zeroing tasks are tied together

- Online maintenance window is split in two, half for database scanning, and otherhalf for online defragmentation

independentlyThrottling interrupts database scanning for specified milliseconds betweenevery 320KB of I/O, which reduces performance issuesPermits page zeroing replication between databases on CCR or LCRIndependent of streaming backup (runs when page is fetched from disk)Disabled by default (set at server level)

Transport dumpster improvements


83/97


LCR & CCR Transport DumpsterTransport Dumpster enabled

- CCR & LCR

- Make sure that you have enough space on each Exchange Hub Transport server

to accommodate the data in the transport dumpster queue for each storage group.

Doesnt mitigate- Drafts folder for any Microsoft Outlook clients in online mode.

- Appointments, contact updates, property updates, tasks, and task updates

- Outgoing mail that is in transit from the client to the Hub Transport server. There is

a period of time during which the e-mail message only exists on the sender's

Mailbox server

Defaults to maximum of

- 18MB/SG/Hub server

- 7 days of retention

Manage Clustered Mailbox Server WizardMove, Start or Stop a Clustered Mailbox Server from EMC (or EMS)

Not supported

- Manage a clustered mailbox server running on Windows Server 2008 from a

computer running Windows XP or Windows Server 2003.

- Manage a clustered mailbox server running on Windows Server 2003 from acomputer running Windows Vista or Windows Server 2008.

IMPORTANT:

Windows Shutdown is not Exchange aware!

If you need to shutdown an active ClusteredMailbox Server, first stop or move it to a

passive node.


89/97


Standby Continuous ReplicationDesigned for scenarios that use or enable the use of standby recoveryservers

Enables a separation of high availability (comprised of service and dataavailability) and site resilience

Uses the same log shipping and replay technology used by LCR & CCRStandard and Enterprise Edition


90/97


Standby Continuous ReplicationSources

- A standalone mailbox server (with or without LCR enabled)

- A clustered mailbox server in a single copy cluster

- A clustered mailbox server in a CCR environment

- Recovery storage groups cannot be enabled for SCR

- Storage group to be replicated must have single database


91/97


Standby Continuous ReplicationTargets

- A stand-alone mailbox server role that does not have LCR enabled for any storage

group (can coexist with other server roles)

- A passive node in a failover cluster where the mailbox role is installed, but no

clustered mailbox server has been installed in the cluster- If using a standby cluster and the clustered mailbox server recovery feature (Setup

/RecoverCMS) as part of the SCR target activation process, the installation paths

for Exchange Server must be the same for SCR source and SCR target computers

- SCR source and target computers must be in same domain, but different AD sites

- Each target can have multiple source servers

- Standard Edition supports a maximum of 5 SCR targets

- Enterprise Edition supports a maximum of 50 SCR targets

SCR Sources and Targets - Deployment Options


93/97


Comparing SCR with LCR and CCRSCR supports multiple replication targets per storage group. LCR andCCR support only one replication target per storage group (the passivecopy)

SCR includes a built-in delay for replay and log truncation activity. This

is useful, for example, in the event of logical corruption of an activedatabase, the delay can be used to prevent logical corruption of an SCRtarget database. LCR and CCR have no such delays.

SCR is completely managed using the Exchange Management Shell.The Exchange Management Console can be used to manage manyaspects of LCR and CCR (SP1)

SCR and BackupsSCR supports backups from the source copy only

LCR and CCR support backups from both the active and passive copy

Log truncation on the SCR source does not wait until all logs have beenreplayed into all SCR targets because SCR target copies can be

configured with large log replay delays (but it waits for log inspection)On an SCR target, a background thread runs every 3 minutes todetermine if any log files need to be truncated

SCR Log Replay & File TruncationReplayLagTime (24h)

- Time to Microsoft Exchange Replication service waits before replaying log

files that have been copied to the SCR target

TruncationLagTime

- Time to Microsoft Exchange Replication service waits before truncating logfiles that have been copied to the SCR target computer and replayed into the

copy of the database. The time period begins after the log has been

successfully replayed into the copy of the database.

Maximum of ("value of ReplayLagTime" or 50 log files")


96/97


SCR Log Replay & File TruncationIf the following two criteria are met, a log file will be truncated:

- Log generation sequence is below log checkpoint for the storage group

- Log file is older than ReplayLagTime+ TruncationLagTime

In an LCR or CCR environment that is extended with SCR, if the

following four criteria are met, a log file will be truncated on the activeand passive copies in the LCR/CCR environment:

- Log has been backed up

- Log generation sequence is below log checkpoint for the storage group

- Passive copy of storage group is in a state that allows log to be truncated

- All SCR targets have inspected the log file
