Greetings from VERITAS Product Management:
I recently completed a competitive analysis of this. Some of the findings:
* The primary point is that you cannot achieve HA by simply dropping a
failover product, ANY failover product, on a pair of servers and walking
away. There are many many other aspects that must be considered. Legato
doesn't sell products that address many of the "supporting" HA issues.
VERITAS supplies a truly comprehensive portfolio of storage management
products, including the industry leading Volume Manager and File System
products, SRVM (Storage Replication for Volume Management) and NetBackup.
Not only do we have kernel-level knowledge of the OS platform (Legato does
not), we more tightly integrate with our portfolio of products than Legato
VERITAS offers Editions; Legato does not. These are bundled, integrated
solutions of multiple storage management solutions from VERITAS. Not only
does VERITAS provide integrated solutions to our customers, and not just
point products, we include solid enhancements like Quick I/O to improve
performance as well as provide HA.
A listing of just some of the strengths of VERITAS Cluster Server:
* Heterogeneous platform strategy (Solaris, HP-UX and NT, with a Linux
port on the way).
* State of the art failover features, including policy-driven,
cascading failover, service level failover: GUI assisted resource group
* Part of a product portfolio that includes kernel components like
Volume Manager and File System (Legato does not have this advantage).
* Comprehensive application monitoring strategy: numerous agents and
flexible API to create additional ones
* Support for more 3rd party disk arrays than any other vendor
(VERITAS has invested extensively in an interoperability lab, and has
automated test suites for unassisted vendor testing). Legato does not make
public any information about their supported storage vendors.
* Simplicity of configuration and manageability: with included JAVA
GUI. Up to 256 clusters of 32-nodes each can be monitored from a single
* A single configuration file for all cluster nodes.
* True wide area failover strategy makes VERITAS offering stronger
than any in the business (VERITAS will introduce in Q2 a disaster recovery
product incorporating replication, VCS and a global management layer).
* With its ClusterX acquisition, VERITAS now has a strategic
management tool which provides entry into Windows environments with
Microsoft Cluster Server and Windows Load Balancing Service.
* SAN partners and real SAN customers !!
Hope this helps,
Product Management: VERITAS Cluster Server

I am already leaning toward the Veritas Product, but I was just
if anyone has any feedback as to which product is better and why? And also,
any pluses and minuses of either product would be great.
