In this Technology Adoption Profile we explore the current state of replication in SMB IT departments and in particular the use of SAN-based replication. We find strong demand for both synchronous and asynchronous SAN-based replication, as well as the need to replicate data within the SMBís own data center facilities, either to a colocated secondary array or to one within 5 km [approximately 3 miles](a campus or metro-style deployment). We also find that in order for SMBs to protect more data using replication, they need replication solutions that are non-disruptive, easy to use, and inexpensive.
Recently, enterprises have seen enormous gains in scalability, flexibility, and affordability as they migrated from proprietary, monolithic server architectures to architectures that are virtualized, open source, standardized, and commoditized.
To stay competitive in today's business climate, organizations must find ways to meet their business needs while controlling IT costs. IT departments face flat budgets and, at the same time, find that their organizations have become increasingly dependent on uninterrupted access to business-critical data. In today's world, prudent IT administrators prepare to recover from two types of disasters as part of a complete Business Continuity and Availability (BC and A) plan.

Intelligent N+X Redundancy, Placement Affinities, & Future Proofing in the Virtualized Data Center
Virtualization brought about the ability to simplify business continuity management in IT. Workload portability and data replication capabilities mean that physical infrastructure failures no longer need impact application services, and they can rapidly be recovered even in the event of complete site failure.
However, Enterprises and Service Providers face new challenges ensuring they have enough compute capacity in their virtualized data centers to support their business continuity requirements, while at the same time not over provisioning infrastructure capacity resulting in unnecessary capital expenditure.

Email, calendaring, collaboration, and mobility solutions are moving from corporate data centers to service provider networks. Service providers can realize far greater economies of scale than most businesses and deliver higher levels of service to more users at a lower cost; in fact, the fewer the users, the higher cost for each. Concentric Hosted Exchange is a fast, reliable and affordable solution for email, calendaring, collaboration, and mobility based on Microsoft® Exchange Server 2007 Service Pack 1 (SP1) and Microsoft Outlook® 2007. Concentric Hosted Exchange provides all of the benefits of Microsoft Exchange and Outlook 2007 without the up-front infrastructure costs or ongoing overhead.
Why do industry analysts agree Silver Peak is the WAN Optimization vendor of choice for offsite data replication? It starts with a unique, next generation architecture. Conceived from the ground up to optimize all IP applications, regardless of transport protocol or application version.
When faced with their EqualLogic replication not completing due to limited WAN bandwidth and consistently missing their RPO, ZLTO needed a solution. Learn how Silver Peakís virtual appliances reduced their bandwidth used for replication by 86%.
Double-Take Move provides migration functionality that dramatically reduces the impact and risk of migrations in the data center and across any geographic distance. Double-Take Move has a patented and award-winning replication engine that provides real-time, byte-level data replication and ensures transaction consistency without affecting users and production applications. Read this whitepaper to learn about the concerns that affect data, application and whole system migration.
This whitepaper looks at why companies choose Riak
over a relational database. We focus specifically on
availability, scalability, and the key/value data model. Then
we analyze the decision points that should be considered
when choosing a non-relational solution and review data
modeling, querying, and consistency guarantees. Finally, we
end with simple patterns for building common applications
in Riak using its key/value design, dealing with data conflicts
that emerge in an eventually consistent system, and discuss
