MCCS (Mantech Continuous Cluster Server) is a high-availability solution for mission-critical computing systems developed by Mantech.
It provides continuous computing environment due to unplanned downtime such as natural disasters, or system failures, or unexpected service interruptions caused by terrors, sabotage or a human error and minimize the downtime due to planned downtime like periodic maintenance.
Normal business of companies in our current industries is conducted in computers, and most of the core information for this needs continuous service on a 24/7 basis. Mission critical systems require no downtime server infrastructure, but you will meet many types of service failures which bring in negative business impacts. 
MCCS protects and make always on your mission critical application from these failure and disaster scenarios.

Features of MCCS

MCCS manages network cards, virtual IP addresses, processes, user programs, SCSILock disks, shared disks, mirror disks, services, Shared disk DR and Oracle database as resources to ensure service keep online.

Service Level Fault Detection and Automatic Failover 

MCCS not only detect on hardware, but it also offers detection on resources (such as network connection, application, platform, disk, etc) as well.
Therefore, if the managed resources are not working properly, it will be either restarted or failovered to the standby server according to the defined action policies.

Support External Shared Storage and Local Disk Replication Environment

MCCS supports both local disk replication and shared disk environment. Thus, it provides enhanced flexibility to make equip any type of storage for the user.

Support Failover Group 

Failover group is including the resources that can be run on only one node at a time.
Application will be switch over to standby node at critical reource is failed in a failover group. 
The resources that included group are online only available node.
For example, IP Address is not onlined on an active node and standby node at same the time. 
Therefore, when IP address is get failed, it and its related resources will be fail over to the standby node. 

Support Parallel Group

Parallel group is a group of resources that are taken online on more than two nodes at the same time. Parallel group cannot failover.
The opposition of this is Failover Group. The group can be online on a node in a cluster within a failover group. 
However, when configured through parallel group, specified application can be online, monitored and terminated on the multiple nodes at the same time in a cluster.
For example, user would like to run backup software on both nodes and be managed by the MCCS, backup software should be online on both nodes at the same time. 
You can use parallel group instead of failover group for this.

Cluster between Heterogeneous Platforms

MCCS is not influenced greatly by the hardware compatibility in a cluster. 
Thus, there is no need to use the exact same hardware between the nodes in a cluster.

Remote Disaster Recovery

MCCS is a high availability that can be configured with no distance limitation between nodes. 
That means standby server can be easily configured on a remote site without extra charge.

Web based management console

MCCS allows user to use a web browser to control MCCS from a local server or remote server. 
At each server, you can connect to the server where MCCS is configured. There is no need to configure an additional environment file. 

Support Multi Group

Group is a set of collected resources dependent on one another to manage resources (ex. Network Card, IP address, disk application etc.) such as failure monitoring, recovery, failover within MCCS. It is also a set of resource to failover.
MCCS can configure more than one group in a cluster. Thus, a configuration of Active/Passive, Active/Active is made possible. (Active/Active means different services on different server)
You can configure parallel and failover goup at the same time. Each group will be managed independently by MCCS in a multi-group environment.

Support IPv6 network environment

MCCS supports both IPv4 and IPv6 network environment configuration. 
Therefore, you can configure the existing been using IPv4, IPv6 network environment, disaster recovery system intact.
