Check out Going from ‘Fat’ to ‘Thin’ Isn’t an Automatic in the Virtual World Either, the latest blog on thin provisioning by DCIG lead analyst Jerome Wendt. He breaks down the various scenarios for when the benefits of thin provisioning are easily realized and when it is not so readily recognized, as there can be issues with deployment and utilization in certain circumstances. He discusses how Veritas Storage Foundation’s SmartMove feature can help larger enterprises maximize their thin provisioning investment.

Jerome Wendt is the President and Lead Analyst of DCIG Inc., an independent storage analyst and consulting firm. Since founding the company in 2006, Mr. Wendt has published extensively in data storage publications and journals covering all facets of storage.

During snapshots, server jobs fail due to Storage is inaccessible to the Recovery Solution Server. The following event appears in the application event:

The data storage location 'F:\Altiris\DataStorage' is offline and not accessible now.
Local Event Code: 0x8008000f
System Event Code: 0x00000020: The process cannot access the file because it is being used by another process.
SbsName: , SbsKey: 0, 0

Data File Synchronization job for Synchronous Storage completes with errors.


Recovery Solution 6.2.2760 (SP2)
Synchronous Storage


It is a physical (timing) problem on the storage.

Definition of the disk latency in a SAN environment is a very difficult task, because there are many physical and logical nodes: operating system, physical disks, RAID, one or more HBAs, one or more fibers (HBA > SAN), ports on SAN, may be fiber-switch, and so on...

Data deduplication is another technology that has gained wide acceptance as a tool to streamline the backup process. Deduplication eliminates duplicate data even when such data is unrelated, greatly reducing the data multiplier effect on data.

For example, if a Microsoft PowerPoint presentation is stored on different file servers multiple times, deduplication ensures that only one copy is stored no matter how many full or incremental backups occur. Organizations may consider specialized appliances to provide backup-to-disk and deduplication functions. However, these appliances add complexity to the data center with more devices to manage and actually add capacity to the environment rather than using what already exists more efficiently.

To be continued...

To make better use of storage resources, organizations can leverage storage management technologies. Storage resource management (SRM), for example, enables IT to navigate the storage environment and identify old or non-critical data that can be moved to less expensive storage. These tools can also be used to predict future capacity requirements.

Managing storage without an SRM tool is like going on a journey without a map. Having a clear plan and objective before taking action is the best assurance of rapid progress and success. Storage managers should ask some questions before cost-cutting:

  • What is the average utilization rate?
  • What is the utilization rate by application?
  • Which applications are growing fastest? Slowest?

SRM technology can help companies make an assessment and provide an enterprise-wide view of the storage environment, which helps identify problem areas, consolidation opportunities, and to create a priority...

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...
