XOsoft's WANSyncHA
Data protection is at the
top of most storage
managers' minds these
days, especially in
companies where
information fuels not only
business decisions but
the business itself. XOsoft
Inc., Burl
ington, MA, has
carved a niche out of the
burgeoning data
protection market with a
small arsenal of business
-
continuity products.
WANSyncHA, the latest incarnation of XOsoft's remote replication package, continuously
replicates data to a local or remote s
ite and provides automatic failover to ensure uninterrupted
access. WANSyncHA's innovation is evident from the start, with its non
-
disruptive agent
installation that doesn't require rebooting servers or stopping applications.
WANSyncHA runs on Windows, Li
nux and Sun operating system servers. Application
-
specific
versions for Microsoft Exchange, SQL Server and Oracle databases provide services such as the
autodiscovery of database files and network configurations. WANSyncHA is hardware
-
agnostic
and operates
with nearly any storage system.
The server agent software monitors all changes to files and directories in the server's file system
and records changes to a journal. The journals are then used to synchronize the master data and
replica data over a LAN or
a WAN.
When synchronizing replica data with master data, WANSyncHA compares the data at the two
servers and sends only the changes to minimize WAN traffic. WANSyncHA can also sense slow
connections and spool changes until sufficient bandwidth is regained
; updates interrupted by lost
connections will recover and resume when the connection is re
-
established.
WANSyncHA can be configured in a many
-
to
-
one arrangement where a single replica at a remote
site serves multiple masters. For more resilient disaster
recovery, WANSyncHA can be used in a
"tree" structure to create multiple replicas at disparate sites.
In a crowded disaster recovery market, WANSyncHA is "outstanding data protection solution,"
said one judge, who cited its "high innovation, high function
ality, high performance and high
value." And with a price tag that starts at approximately $5,200 to $10,000 per license, it's also a
cost
-
effective approach to disaster recovery.
WANSyncHA, XOsoft's remote replication package, can m
