1.        VERITAS Volume Replicator：implement data replication in your disaster recovery strategy
2.        VERITAS SANPoint Foundation Suite provides simple and reliable data sharing in an enterprise-level SAN environment by implementing a clustered file system that leverages the strengths of file and volume management technologies, combined with sophisticated failover and clustering logic, to ensure consistency and availability. includes:
        – VERITAS Volume Manager
        – VERITAS Cluster Volume Manager
        – VERITAS File System
        – VERITAS Cluster File System
VERITAS SANPoint Foundation Suite HA Adds VERITAS Cluster Server to VERITAS SANPoint Foundation Suite for faster application failover
3.        Storage virtualization is the process of taking multiple physical storage devices and combining them into logical (virtual) storage devices that are presented to the operating system, applications, and users. not restricted to specific hardware devices
4.        Three main types of storage virtualization used today are:
Storage-based
Host-based
Network-based
5.        Storage-based storage virtualization refers to disks within an individual array that are presented virtually to multiple servers.
6.        Host-based storage virtualization refers to disks within multiple arrays and from multiple vendors that are presented virtually to a single host server.
7.        software-based solutions, such as VERITAS Foundation Suite,provide host-based storage virtualization.
8.        By combining VERITAS Foundation Suite with clustering technologies,such as the Cluster Volume Manager available with SANPoint Foundation Suite HA, storage can be virtualized to multiple hosts of the same operating system.
9.        Network-based storage virtualization refers to disks from multiple arrays and multiple vendors that are presented virtually to multiple servers.
10.        VERITAS File System is a quick-recovery journaling file system
11.        Snapshot of a file system provides an internally consistent, read-only image for backup.
12.        Performance bottlenecks can be located and eliminated using VxVM analysis tools.
13.        With VxFS, several add-on products are available for maximizing performance in a database environment.
