- Veritas Storage Foundation (SF) – Storage Foundation brings advanced volume management, quick recovery, and storage fault tolerant enterprise applications. Features and capabilities include items such as storage migration, storage agnostic mirroring, thin provisioning reclamation, and capacity insight and management.
- Veritas Dynamic Multi-pathing (DMP) – Veritas Dynamic Multi-pathing for VMware environments provides array integration and advanced pathing failure and load balancing policies for VMware ESXi environments.
- Veritas FlashSnap – FlashSnap, which requires SF and is included with certain SF and SFHA bundles, integrates with Microsoft VSS framework on the Windows platform and application specific awareness on the Linux platform to ensure application consistent snapshots of application data that reside on SF volumes. FlashSnap can be leveraged to ensure application consistent quick recovery, testing replicated data consistency and off host data mining and reporting.
- Veritas Volume Replicator (VVR) – Volume Replicator, which requires SF, provides node to node, over-IP block based replication at the volume level. VVR can be leveraged to provide the replication of the application data that will need to be recovered in a DR event.
- Symantec ApplicationHA (AppHA) – Symantec ApplicationHA provides the base fundamental application monitoring and fault remediation needed for applications across guests running Windows or Linux. Base fault remediation includes application restart and virtual machine restart. Advanced remediation includes image based recovery from a backup; currently integrated with Backup Exec.
- Veritas Cluster Server (VCS) – Veritas Cluster Server, which can be used independently or with SF, extends application monitoring and fault remediation to include application failover for a wide range of topologies including single site high availability, campus high availability, campus disaster recovery and wide area disaster recovery.
- Cluster File System (CFS) – Cluster File System, a cluster integrated shared file system, assists in ensuring greater availability of applications by reducing downtime in an application failover since the dependent storage resources and file system are simultaneously available and accessible by all targeted failover nodes. CFS is applicable to virtual machines running Linux.
- Storage Foundation High Availability (SFHA) – Storage Foundation High Availability combines together SF and VCS to provide a full end to end solution for storage management through high availability and disaster recovery.
- Symantec High Availability Console – The Symantec High Availability Console provides an in context management experience for applications protected by Application HA and VCS within a VMware ESXi environment via a vSphere plug-in. The console provides capabilities such as push installation to Windows and Linux guests for ApplicationHA and VCS packages, simplified application availability configuration experience, dashboard view of application health and administrative driven remediation management actions.
- If the OS instance is connected to the network, running the installer from a remote node and performing a push installation.
- Running the installation directly within the guest OS instance.
- Push installation from the Symantec High Availability console.
