CA XOsoft High Availability Exchange - Exchange Protection / Exchange Failover Solution
CA XOsoft High Availability Exchange provides Exchange protection through automated Exchange failover that specifically addresses the nuances of Microsoft Exchange. CA XOsoft High Availability Exchange provides concise, tailored Exchange installation-specific options, and requires no further IT intervention to complete the processes of failover detection, Exchange failover and bringing the hotsite/replication site online.
For further ease of use, CA XOsoft High Availability Exchange is built specifically for Exchange protection and the Exchange environment as it reads the Active Directory, the server registry and Exchange 2000/2003 files, and quickly gives an administrator a profile of where things are, how they are set and options for synchronization intervals. Our Exchange failover solution doesn't require customization details and script writing for Exchange administrators to struggle with.
Exchange Protection and Exchange Failover
CA XOsoft High Availability Exchange provides complete Exchange protection and Exchange failover by automatically detecting when the primary site is down, then recasts the hotsite's mirror to Exchange users. Our Exchange failover product automatically brings Exchange services back online by using an existing connection to reroute operations to the secondary site. In an independent laboratory test, only CA XOsoft High Availability Exchange did not lose any messages during the Exchange failover process.
Be sure to view our Exchange protection recorded webcasts and demos which walks through our Exchange failover solution.
For compliance and testing purposes, CA XOsoft's Assured Recovery works in conjunction with our disaster recovery and high availability solutions by enabling a full test of the recoverability of your data on a replica system. This is done by actually starting up application services on the replica and performing whatever operations are required to verify the integrity of the data, including updates to the database, without any need to perform an expensive resynchronization or to leave the production system vulnerable.

Q. What is the difference between WANSync and CA XOsoft High Availability?
A. CA XOsoft High Availability offers a superset of the capabilities of WANSync. In particular, CA XOsoft High Availability adds the capability for push-button or automatic failover of clients from the production server to a secondary replica server, without any need to reconfigure clients, as well as the ability to automatically monitor the status of the production server and the applications running on it. Once the Master server is restored to its original state, CA XOsoft High Availability allows the IT administrator to reinstate the Master Server or "automatically failback" from the Replica with no loss of data or application availability. |
Exchange Failover
CA XOsoft, a leading provider of continuous application availability
software, provides a solution tailored to handle the specific nuances of MS Exchange failover, high availability and disaster recovery.
CA XOsoft has developed CA XOsoft High Availability Exchange for Exchange protection, which
enable the availability of Microsoft Exchange through high availability
replicas that enable Exchange failover, even across different IP
networks.
CA XOsoft High Availability Exchange for Exchange protection secures entire Exchange
servers, backs them up and constantly synchronizes them with either
local or remote replicas in real time - MS Exchange failover. Our patented soft installation avoids system shutdowns and does not require that Exchange services
be restarted, ensuring that lost productivity is not an issue.
Intelligent, binary differentiation-based algorithms allow CA XOsoft High Availability
Exchange to continuously carry out byte-level updates, even over
intermittent WAN and slow TCP connections. Should the Exchange
server fail for any reason or have to be shut down for maintenance,
a CA XOsoft High Availability Exchange failover replica,
either local or halfway around the globe, will automatically take its place to provide true Exchange protection and automated Exchange failover.
Key Benefits and Features of Exchange Protection and Exchange Failover
Meeting Compliance Regulations, Testing, and Backup/Snapshot Assurance
For those industries mandated by the government or its board of directors to provide documented proof that their disaster recovery replicas will function in the event of downtime, CA XOsoft's Assured Recovery is the solution to this previously very expensive undertaking. With Assured Recovery, IT professionals are provided with documented assurance that the replica is in a valid state. Once the test has verified the data to be fully consistent, appropriate staff can be alerted with the status of the test, and additional actions can be triggered on success, such as running a snapshot or a backup of the data for archiving purposes. Note: Assured Recovery testing is tailored to the particular applications that are being protected, including Exchange, SQL and Oracle.

CA XOsoft High Availability Exchange - Exchange Protection at
Work
With automated Exchange server component discovery and MS Exchange replication
setup, installation and configuration is easy. The CA XOsoft High Availability
Exchange service running on the master Exchange server maps and
retrieves all Exchange database components, including storage groups
and associated public and private information stores, system directory
and log files.
Once paths to Exchange database components have been retrieved,
synchronization with CA XOsoft High Availability Exchange replicas
commences, creating up-to-date copies of the Exchange server being
secured. CA XOsoft High Availability Exchange tracks all incoming
changes to master Exchange server files (at the file system level),
and replicates these changes in real time. Transactional integrity
is maintained constantly, as updates are applied to replicas in
the exact same order in which they were written to the master Exchange
server.

Exchange Failover / Failback
Should the master Exchange server become unavailable, our Exchange protection software
automates the failover steps to the MS Exchange replication site. CA XOsoft High Availability
Exchange monitors all critical events, including global server failure
and Exchange service failure, and either automatically or on command,
initiates failover to a standby replica site. Exchange failover may include
IP take-over (if the standby site is implemented within the same
network segment) or DNS redirection, when the remote standby site
is located on a different IP network (cross-network failover).
Review NetworkWorld's Exchange failover product comparison.
Single-Network Exchange Failover / Failback
In a single segment scenario, a CA XOsoft High Availability Exchange
master (M1 in the diagram below) is assigned a secondary IP address.
This IP address is used for replication with a replica server (R1
in the diagram below). In case M1 fails, it will retain the secondary
IP address, while its primary IP address is reassigned to R1. This
procedure is fully automated, and involves the following events
on the replica:
- IP take-over
- Startup of Exchange services
- Mounting of Exchange databases
- Updating of user records in Domain Controller with new Exchange
server name
Complete service availability is achieved, with our Exchange failover users are instantaneously switched to the replica server (R1) and through a completely automated process. Once the master
server is back online, reverse replication (from replica to master)
can be automatically initiated, ensuring that the master is fully up-to-date
when users are switched back to it.
Cross-Network Exchange Failover / Failback
When master and replica do not reside on the same IP network, IP
address transfer is impossible. CA XOsoft High Availability Exchange
failover overcomes this limitation through intelligent manipulation of DNS
lookup. Should the master server fail, CA XOsoft High Availability
Exchange will route client applications to a replica server with
an alternate DNS name, again providing users with complete and seamless
Microsoft Exchange service availability.
