High Availability for SAP by EXPRESSCLUSTER
Today, more and more IT systems have been migrated into virtualized environment or public/private cloud services aiming for optimization of IT assets. However, regardless of the increase in diversity, keeping the IT system always up and running is essential for success of the business.
EXPRESSCLUSTER, the leading HA/DR solution from NEC offers market-proven quality of high availability for various applications including SAP.
EXPRESSCLUSTER X 3.1 for SAP NetWeaver
NEC launches the SAP HA Interface Certified software, EXPRESSCLUSTER X 3.1 for SAP NetWeaver. Please find the details at press release.

- Microsoft SQL Server (Windows only)
EXPRESSCLUSTER Benefits for SAP
High Reliability & Flexibility
EXPRESSCLUSTER offers many sophisticated features which ensures high availability of critical applications. Its wide range of monitoring capability maximizes uptime for any applications by detecting any failures which may lead to system disruption.
In addition, comparing to other high availability clustering solutions including WSFC (Windows Server Failover Clustering), it also offers higher flexibility enabling to meet each and every customers requirement.
For example, EXPRESSCLUSTER supporting synchronous/asynchronous data mirroring does not require shared disk which most of the high availability clustering solutions do and this enables customers to configure more cost effective clustering solution.
Of course, it also supports clustering with shared disk as well. Similarly, EXPRESSCLUSTER does not require Active Directory to manage cluster which normally requires users to have separate server. Minimize the complexity and cost, but maximize the availability of the application is what EXPRESSCLUSTER does.
Not Only Windows, But Also Linux Supported
As well as Windows, EXPRESSCLUSTER has been deployed for a large number of protecting Linux systems. Today, choosing Linux OS for critical application in order to optimize the IT cost is normal, and EXPRESSCLUSTER supporting wide range of Linux OS is the solution which protects your Linux system.
< Supported OS >
- Windows Server
- Red Hat Enterprise Linux
- SUSE Linux Enterprise Server
- Asianux Server
- MIRACLE LINUX
- Turbo Linux
- Cent OS
Wide Range of Virtualization Supported
Virtualization is one of the best way to consolidate the servers and optimize the usage of IT resources. However, if on the other hand, it also consolidates the risk of system failure which can be said as "All Eggs In One Basket". This is why it is essential to ensure high availability especially for virtualized environment.
EXPRESSCLUSTER offers application level protection for virtual machines running on any major hypervisors. Utilizing high availability features of hypervisors itself can be one of the effective way to add high availability to the virtualized system. However, they normally do not support application level protection which means there are still certain level of risk of system disruption.
For applications which requires extra high availability, combined usage of EXPRESSCLUSTER and high availability features of hypervisor will bring one level higher availability to the virtualized system.
< Supported Virtualization Platform >
- VMware vSphere
- Microsoft Hyper-V
- Citrix XenServer
- Linux KVM
- Sun Solaris Container
- IBM Power VM
