To achieve near-zero downtime, mission-critical systems cannot afford to have single points of failure in servers, storage or interconnects. High-availability (HA) is now a necessity in most modern IT systems. HA is most effectively achieved in server and storage systems through server clustering, which allows systems to survive hardware or software failures without users experiencing downtime.

Orient specializes in designing, deploying and supporting clustered HA systems for a variety of applications and environments. Some of the supported clustering environments are listed below:

  • Microsoft Cluster Server (MSCS) for Exchange, SQL Server and Windows Server clusters
  • Oracle Real Applications Clusters (RAC) for HA Oracle database applications

Nexus can assess your HA needs then design, integrate, test and support a single or multi vendor clustering solution.

Our factory-trained and certified engineers are current with the latest clustering technologies and products, and use field-proven “Best Practices” to design and deploy “best-of-breed” solutions to fit your exact requirements and budget.

Our Software team includes Oracle and MS SQL certified DBAs so that we can provide you with full, top-to-bottom assistance with your Oracle clustering project.
