During periods of economic growth, organizations may be tempted to take the “quick fix” to storage management problems. The incremental cost of adding storage is relatively small and can be absorbed by the budget. Such a short-cut may facilitate faster project roll-out, but it also leads to underutilized storage. Many organizations operate at only 30 to 40 percent utilization. According to InfoPro, the average is 35 percent.

Accurate storage allocation is difficult because data growth rate information is incomplete or unavailable. Consequently, storage allocation does not correlate to consumption. New applications, with no historical trend data, receive storage allocation on a “best estimate” basis. If the allocated capacity is too high, then the excess capacity may languish unused for the life of the array.

Needless spending is the primary consequence of benign neglect. Having an array only 50 percent utilized is like paying...

The following services have just been updated. Please find below new functionalities now available to you:

Veritas Installation Assessment Service [VIAS]

  • Combined Notification Center – Users can create user defined ad-hoc or environment specific notifications for new patches, ASL/APM releases, new versions of the HCL and updates to Veritas Operations Services (VOS) from one easy-to-use web application. Both the notification center and VIAS reports now connect directly with Patch Central allowing the applications to synergistically cross-leverage customer data
  • Windows Support (Beta) – Support for the SFWHA “ConfigChecker” application to pre-qualify Windows environments

Creating highly available Oracle databases with immediate failover is expensive, though sometimes justifiable. However, organizations whose SLA includes near-minute failover can consider a Veritas Clustered File System (CFS) solution. CFS is an option within Storage Foundation (SF); SF users need a simple license key to turn it on. Application clustering to ensure high availability of databases without Cluster File System results in failover times that become increasingly longer as more disks, volumes, and file systems are added into the configuration. Furthermore, if a file system corruption occurrs, the failover time will be dramatically impacted while the file system recovers.

Cluster File System enables the Veritas Oracle Disk Manager (ODM) interface, providing near raw disk performance with all the benefits of a file system. This not only improves the speed of your data base when running on a file system, it improves failover times by reducing the time it takes for...

 Even as IT organizations face significant budget pressure, business carries on and continues to drive storage growth. So, how can IT organizations meet organizational needs without buying more storage? Let’s do a little math.

First, two baseline numbers are important. Industry analysts peg average storage utilization at 35% and the compound annual growth rate (CAGR) for storage at 50%. We can now apply these two numbers whatever assumption we wish. To make the calculation easy, assume that we have a total capacity of 100 TB with a 35% utilization (35 TB). With a 50% CAGR, we would utilize 52.5 TB (52.5%) and the end of 12 months and 78.75 TB (78.75%) after 24 months. Thus, the “average” organization can survive up to two years without buying another byte of storage, if only they can find a way to utilize what they have. If you know your utilization and CAGR, you can easily apply this calculation yourself to see how long you can survive without...

A group of DBAs that manage large databases at a large federal government agency had the challenge of migrating a mission-critical 35 TB database from a Fujitsu 2500 running Solaris to an IBM P595 running AIX within a 4 hour maintenance window. Using the tools that the database vendor offered, the estimated time to move that much data was in the neighborhood of 3 weeks, which was unacceptable. Database migration tools from another company were evaluated but they were cost prohibitive.

A Symantec Sales Engineer suggested that these DBAs use the Portable Data Container (PDC) feature within Storage Foundation, which was already deployed in their infrastructure. He explained that with PDC, instead of moving the data from one storage location to another, the data can be unmounted from the Solaris system and mounted on the AIX system. The entire process would take no more than 30 minutes.

The PDC feature was tested in the customer’s lab environment and was put in...

Hello from the Storage Foundation/High Availability Technical Product Management team, and welcome to the new Symantec Connect!  In this first VCS blog entry under the new format, we'll take a look at reducing the cost of HA by building larger, more "intelligent" clusters.

When most people think of clustering, they think of a 2-node, active/passive cluster in which a mission-critical application runs on one system (the active node) while a stand-by system (passive node) is ready to take over if something fails on the active node.  This approach works fine in an environment with one or maybe two mission-critical applications, but consider the costs of this approach in an environment with 10 or 15 or 20 mission-critical applications.

To avoid the costs of excessive hardware sparing, an "N+1" approach is often implemented in which "N" represents the number of active nodes and "+1" represents a single spare (idle) server....

Welcome to the new Symantec Connect and specifically to the Clustering and Replication Community. What a great opportunity to really build a vibrant and engaging community all about high availability and disaster recovery!

Now to introduce myself, I’m Eileen Allan, the new Clustering and Replication Community Manager. I’ll be managing and moderating the content for this area of Symantec Connect. Please feel free to drop me a note with your thoughts, ideas or suggestions. I’d be interested to learn what kind of information is important to you. What topics are of interest, or what problems are you trying to solve . . and by all means, let me know what you think of the new site.

Everyone is invited to participate and share technical knowledge and experience with the community. Take a few minutes to start a forum discussion or ask a question. Your expertise can help someone else in the community solve a problem. Why not write an article or a blog...

Symantec's Dan Lamorena, Senior Product Marketing Manager, and Eric Hennessey, Director, Technical Product Management, continue their introduction of Veritas Cluster Server One and further explain its value in providing high availability in a multi-tiered, multi-platform application environment.

Eric: Another critical element of Veritas Cluster Server One (VCS One) is the ability to manage virtualized environments such as VMware, Solaris Containers and LDOMs, IBM mPars, and others. Most of these platforms have their own "high availability (HA)" solutions; however, these solutions don't have some of the enterprise-ready features that customers require like rich application monitoring and failover. Further, these HA solutions only work on that particular platform and most IT organizations have a mix of Windows, Unix, and server virtualization in their data centers. This means that the IT organization has different tools on different...
