Symantec Cluster Server (VCS) connects multiple, independent systems into a management framework for increased availability. Each system, or node, runs its own operating system and cooperates at the software level to form a cluster. VCS links commodity hardware with intelligent software to provide application failover and control. When a node or a monitored application fails, other nodes can take predefined actions to take over and bring up services elsewhere in the cluster.

VCS |
Minimizes downtime
Facilitates the consolidation and the failover of servers
Effectively manages a wide range of applications in heterogeneous environments
Provides data integrity protection through I/O fencing
Provides High Availability of applications

Dynamic Multi-Pathing (DMP) provides multi-pathing functionality for the storage devices configured on the system. The product creates DMP metadevices (also known as DMP nodes) to represent all the device paths to the same physical LUN.
|
DMP |
Extends DMP metadevices to support OS native logical volume managers (LVM)
Provides improved storage I/O performance with load balancing
Provides storage path failure protection and fast failover
Centralizes storage path management regardless of operating system or storage hardware
|
Symantec Replicator Option enables cost-effective replication of data over IP
networks for disaster recovery, giving organizations an extremely flexible, storage hardware independent
alternative to traditional array-based replication architectures.
|
VVR |
Volume Replicator (VVR)
Provides block-based continuous replication
Provides effective bandwidth management
Supports cross-platform replication, and replication in a Portable Data Container (PDC) environment

Storage Foundation (SF) is a storage management offering that consists of Veritas Volume Manager (VxVM), Veritas File System (VxFS), and DMP.
Veritas Volume Manager is a storage management subsystem that enables you to manage physical disks and logical unit numbers (LUNs) as logical devices called volumes.
Veritas File System is an extent-based, intent logging file system.

DMP, VxVM, VxFS |
Increased storage utilization across heterogeneous environments
Deduplication and compression
Automated storage tiering
Centralized storage management
Easy OS and storage migration with minimum downtime
All benefits of DMP
|
Storage Foundation High Availability (SFHA) includes all the functionality of SF plus the high availability of VCS.

Storage Foundation Cluster File System High Availability (SFCFSHA) extends Symantec Storage Foundation to support shared data in a storage area network (SAN) environment. Multiple servers can concurrently access shared storage and files transparently to applications.
With the Flexible Shared Storage (FSS) feature, you can use local or commodity storage for Cluster Volume Manager (CVM) or Cluster File System (CFS).
CVM extends VxVM to support shared disk groups. CFS extends VxFS to support parallel clusters.

Storage Foundation for Oracle RAC (SFRAC) is an integrated suite of Symantec storage management and high-availability software. The software is engineered to improve performance, availability, and manageability of Real Application Cluster (RAC) environments.
|
DMP, VxVM, VxFS, VCS, CVM, SFCFSHA, plus support for Oracle RAC |
|
Storage Foundation for Sybase ASE CE is an integrated suite of Symantec storage management and high-availability software. The software is engineered to improve performance, availability, and manageability of Sybase ASE CE on UNIX platforms.
|
DMP, VxVM, VxFS, VCS, CVM, SFCFSHA, plus support for Sybase ASE CE |

Symantec ApplicationHA provides monitoring capabilities for applications running inside virtual machines in the virtualization environment. Symantec ApplicationHA adds a layer of application awareness to the core high availability functionality that is offered by Symantec Cluster Server (VCS) in the physical host. Symantec ApplicationHA is based on VCS, and uses similar concepts such as agents, resources, and service groups. However, Symantec ApplicationHA has a lightweight server footprint that enables faster installation and configuration in virtualization environments.
|
Symantec ApplicationHA, VCS |
Out of the box integration with VCS
Full visibility and control over applications with the ability to start, stop, and
monitor applications running inside virtual machines
High availability of the application as well as the virtual machine inside which
the application runs
A series of incremental fault management remedies that include application restart, graceful virtual machine reboot, forceful virtual machine reboot, and vMotion.
ApplicationHA tries the first two remedies and upon failure prompts VMwareHA to try the next two remedies.
Standardized way to manage applications using a single interface that is
integrated with the Veritas Operations Manager console
Specialized Application Maintenance mode, in which Symantec ApplicationHA enables
you to intentionally take an application out of its purview for maintenance or
troubleshooting
|
Veritas Operations Manager provides a centralized management console for Symantec Storage Foundation and High Availability products. You can use Veritas Operations Manager to monitor, visualize, and manage storage resources and generate reports.
|
N/A |
Centralized, standardized way to manage the various features in the Storage
Foundation products
Visual interface for managing individual
hosts and their storage
Visibility into all instances of Storage Foundation
that are running in the datacenter, across multiple operating systems

Symantec Cluster Server (VCS) agents provide high availability for specific resources and applications. Each agent manages resources of a particular type. Typically, agents start, stop, and monitor resources and report state changes.
In addition to the agents that are provided in this release, other agents are available through an independent Symantec offering called the Symantec High Availability Agent Pack. The agent pack includes the currently shipping agents and is re-released quarterly to add the new agents that are now under development.
You can download the latest agents from the Symantec Operations Readiness (SORT) website at:
