Multi-Node Mirroring Support
Supports multi-node mirroring technology, allowing a single server to simultaneously mirror data to multiple nodes, creating a mutual backup architecture across nodes. By leveraging EXPRESSCLUSTER’s pioneering multi-node mirroring technology, you can achieve more flexible configurations without sacrificing system reliability or performance, further saving hardware investment.
Multiple Cluster Working Modes
Supports not only traditional single-active (Active/Passive) and dual-active (Active/Active) modes, but also N and N+1 multi-node cluster backup.
(1)Active/Passive
(2)Active/Active
(3)N+1 Backup
(4) M+N Backup
Remote Disaster Recovery for Mirror Clusters
Another innovation in EXPRESSCLUSTER’s application method is applying mirrored clusters to remote disaster recovery solutions. Typical remote disaster recovery solutions often require demanding network environments, complex implementation, and high costs. However, the remote disaster recovery solution using EXPRESSCLUSTER mirrored cluster software not only backs up business data offsite but also monitors software and hardware resources. In the event of a primary node failure, it can automatically restore services on the backup node, minimizing service downtime to the greatest extent possible.
Virtualization Technology Support
EXPRESSCLUSTER supports virtual clusters. It can serve as a high-availability cluster solution at the virtual machine level, or it can build high-availability clusters for applications running on virtual machines.
When a service running on a virtual machine fails, EXPRESSCLUSTER can switch it to another virtual machine. If the virtual machine software itself fails, or the physical server fails, EXPRESSCLUSTER can switch the entire virtual machine to another physical server. Furthermore, virtual machines can be used to back up physical servers. For example, if you want to use one server to back up physical servers running different operating systems, combining virtualization technology with EXPRESSCLUSTER makes this easy to achieve.

Supports Up to 32 Nodes with Excellent System Scalability
As your business expands, you can dynamically add cluster server nodes, scaling up to a maximum of 32 nodes;
Multi-Platform Support
Supports almost all mainstream Windows and Linux operating system platforms currently used domestically, such as Windows NT/2000/2003, RedHat, Turbolinux, MIRACLE LINUX, Novell SUSE LINUX, RedFlag, etc.
64-bit Architecture Support
Supports servers and operating system platforms based on 64-bit architectures such as IA-64, EM64T, and PPC64.
Flexible Storage Device Selection
Supports most mainstream storage devices currently available domestically, including products from renowned storage manufacturers such as NEC, IBM, Dell, EMC, HP, Lenovo, and Sugon. It supports not only single-path disk enclosures but also multi-path disk enclosures, and provides support for iSCSI-type enclosure devices as well.
Comprehensive Application Protection Support
EXPRESSCLUSTER can protect a vast array of applications and services, covering almost all mainstream applications and services on Windows and Linux platforms, such as Oracle, SQL Server, DB2, Sybase, PostgreSQL, PowerGres, MySQL, Exchange Server, Apache, Samba, etc. (see “Supported Software” for details). Beyond these mainstream applications and services, it can also protect custom applications and services developed by users.
Deep-Level Stall State Monitoring
In addition to conventional monitoring of applications and services (i.e., monitoring at the process death level), EXPRESSCLUSTER also offers a series of monitoring options, such as Database Agent, Internet Server Agent, Application Server Agent, File Server Agent, etc. These monitoring options can watch for stall states in databases and other applications/services running on EXPRESSCLUSTER, thereby providing deeper protection for users’ critical business systems.
