core business communication up fabric am
incorporated
is based on email messages therefore the
need for a highly available messaging
system
is crucial for the organization
currently Exchange Server 2007 is the
messaging system
used by fabric am although Exchange
Server 2007 provides features were
deploying high-availability
inside resiliency solutions it has
certain limitations
fabric and realized there with Exchange
Server 2007
they were incurring high hardware cost
for example
clustered servers require dedicated
hardware to provide a highly available
Exchange environment
at least four Exchange servers are
needed to achieve full redundancy have
the primary components have an Exchange
server 2007 deployment
this is because only the mailbox server
role
can be installed on a node in the
cluster Exchange Server 2007 requires
high administrative overhead
management oven Exchange Server 2007
high availability solution requires
administrators to master
both exchange and Windows failover
clustering concept
which is moving network identities and
managing cluster resources
because failover up a clustered mailbox
server occurs
at the server level administrators have
to fail over the entire clustered
mailbox server
to another node in the cluster or leave
the users on the field database
offline for a few hours while restoring
the database from backup
additionally when troubleshooting issues
related to cluster mailbox servers
administrators need to use Exchange in
cluster tools
for analyzing in correlating logs and
events from the Exchange organization
and cluster to overcome these cost and
administrative issues have Exchange
Server 2007
fabric and decided to upgrade their
messaging system
to Exchange Server 2010 with the move to
Exchange Server 2010
fabric am is now able to reduce their
hardware cost
significantly for example Exchange
Server 2010
enables multiple server roles to coexist
on servers
they provide high availability thereby
reducing the number of dedicated servers
cost could also be controlled because
fabric and can now achieve full
redundancy
by using just new servers moreover
the storage improvements in Exchange
Server 2010
now allows the use of serial advanced
technology attachment
say die hard disks and redundant array
have
inexpensive disks rate less just a bunch
of discs:
J Budd configurations resulting in
significant cost savings
apart from cost Exchange Server 2010
has also helped fabric am reduce their
administrative overhead
administrators at fabric a.m. are no
longer required to build a failover
cluster
in order to achieve high availability
this is because
failover clusters are now created
behind-the-scenes
when the Exchange server 2010 I
availability feature
is enabled moreover even after exchanges
been deployed as a stand-alone server
administrators can add high availability
to their exchange server 2010
environment
also because storage group no longer
exist and mailbox databases
are portable across all Exchange Server
2010 mailbox servers
administrators in easily move databases
whenever needed
additionally for troubleshooting issues
administrators can use
a view that combines events from
exchange and the operating system
Exchange Server 2010 also includes many
modifications to its core architecture
that provided fabric am with enhanced
server availability
in server resilience for example the
cluster continuous replication
CCR and stand by continuous replication
Secr features have Exchange Server 2007
have been combined enhanced into the
database availability group
the AG feature this feature provides
automatic failover protection at the
individual mailbox database level
and not at the storage group level this
results in failover actions
to complete in lesser time than in the
earlier versions of Exchange
consequently administrators have fabric
and could achieve a high level up time
in Exchange Server 2010 wanna be a new
transport dumpster features
is decreased transport dumpster size
through truncation feedback
to improve cash efficiency in addition
if the mail queue gets corrupted it will
now be rebuilt
in Exchange Server 2007 the transport
dumpster feature
help prevent males from being lost
during the time taken for a cluster to
failover
however administrators became concerned
about the message losses that occurred
while they are in transit Exchange
Server 2010
has been able to address this issue with
the new shadow
redundancy feature that provides
redundancy for messages
for the entire time they are in transit
before adopting Exchange Server 2010
administrators had fabric M used to
perform system maintenance tasks during
nights
or weekends however with Exchange Server
2010
they are now able to perform these desk
even during business hours
this has been possible because if the
improved online mailbox moves
feature in Exchange Server 2010
this feature allows administrators to
move mailboxes between databases
even while end users are still accessing
it Exchange Server 2010
has not only helped fabric and reduce
the cost
and complexity of deploying in the email
solution
what it has also provided them with
improved up times
and enhanced flexibility for
administrators
