About the Veritas InfoScale components

Veritas InfoScale products is a set of components that provide storage administration and management in a heterogeneous storage environment.

This section can help you determine which product you need.

Table: Veritas InfoScale components comparisons shows the benefits of each product and its components.

Components

Benefits

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

Veritas Replicator 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

VFR

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

File Replicator (VFR)

  • Provides file-based periodic replication

  • Supports reversible data transfer

  • Deduplication

  • Supports protection of the target file system from accidental writes

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

Veritas InfoScale products include all the functionalities of SF plus the high availability of VCS.

DMP, VxVM, VxFS, VCS

  • All benefits of DMP

  • All benefits of SF

  • All benefits of VCS

Storage Foundation Cluster File System High Availability (SFCFSHA) extends 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 Storage Sharing (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.

DMP, VxVM, VxFS, VCS, CVM, SFCFSHA

  • All benefits of DMP

  • All benefits of SF

  • All benefits of VCS

  • Increased automation and intelligent management of availability and performance across shared storage

Veritas InfoScale Operations Manager provides a centralized management console for Veritas InfoScale products. You can use Veritas InfoScale Operations Manager to monitor, visualize, and manage storage resources and generate reports.

N/A

  • Centralized, standardized way to manage the various features in the Veritas InfoScale products

  • Visual interface for managing individual hosts and their storage

  • Visibility into all instances of Veritas InfoScale products that are running in the datacenter, across multiple operating systems

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 Veritas InfoScale offering called the 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 Services Operations Readiness (SORT) website at:
