In the article Commoditizing High Availability and Storage using Flexible Storage Sharing I described my first attempt to create a two node cluster based on Flexible Storage Sharing within Symantec Cluster File System and the nice results that I got. My next step was to increase the node count as I wanted to move to an architecture where a database will be running in each of the nodes. The first step here was to add a new node to the cluster.

Many times I get the question about how easy or difficult is to add a node to the cluster. This was a good opportunity to document what I did here. Our engineers at the Common Product Installer (CPI) group have done a great job over the years and now adding a node to the cluster can be done with a few easy steps.

The first thing to do is deploy the packages on the new server. There are several ways to do...

It was during this year VISION conference in Las Vegas when I got a very interesting question from Mike. He was running my Flexible Storage Sharing (FSS) lab and he asked me: “So Carlos, with FSS I can use internal HDDs and provide a highly available service, commoditizing the HW and avoiding any SAN need”. Then I started talking about the work I have being doing in the lab for the last months. And it was when I realized I had to start writing and publishing about that work, so here we go.

During FSS deployment we all were very excited about the capabilities to bring any application working close to the CPU, especially when using internal SSDs. We worked very closely with Intel and we published the white paper Remove the Rust: Unlock DAS and go SAN-Free. This white paper described how I could increase by four times the performance of a database. But what happens if I do not...

Many organizations believe that they have a solid and ready to execute business continuity plan in case of a disaster.  However, according to a 2010 Forrester survey*, “many organizations have lulled themselves into a false sense of security” when it comes to how they value their preparedness.  The survey also revealed that proper plans of planning, testing, and maintenance are not actively tested as often as they should be.  This lack of preparedness is a costly strategy in terms of revenue, employee productivity, reputation, among  other factors.  Specifically, the survey found that an average recovery took 18.5 hours with 4.8 hours of data loss.  In addition, according to a StorageCraft blog, in 2011, disasters cost $52B versus $10B in 2010.  These numbers clearly indicate that organizations must evaluate their...

As IT organizations continue to rapidly deploy virtualization, ensuring availability of applications in their virtual environments is critical. Since its initial launch last year, Symantec ApplicationHA helped numerous customers quickly and automatically recover from a wide range of application and infrastructure failures inside virtual machines.   

Symantec recently announced the latest release of Symantec ApplicationHA 6.0 for Windows. This release includes integration of Symantec ApplicationHA with Symantec Backup Exec which takes application availability to a new  level by providing another level of remediation to recover from failures in VMware virtual environments. This new feature provides virtual machine image restoration as a possible remediation mechanism if application restart and virtual machine restart both fail in recovering an application. In the event of a corrupt virtual machine or OS image, Symantec ApplicationHA coordinates with...

For some organizations, the idea of virtualizing their mission critical applications is perceived to be more riskier and its advantages are not yet compelling to make the switch.  In fact, according to Symantec's latest Virtualization and Evolution to the Cloud Survey, 40% of CEOs and 42% of CFOs are reluctant to make the leap to virtualization.  Some of the cited reservations are around downtime and the lack of visibility into virtualized environments.  However, IT users can get around these challenges by making sure that they deploy virtualization tools that are suited for their particular needs. A foolproof virtualization plan can deliver cost savings, efficiency, increased productivity, high availability, disaster recovery, etc.  Recently, Dan Lamorena, Product Marketing Director within Symantec's Storage and Availability Management Group authored an article in the ...

SwapDrive (now part of Symantec)
By far the world’s largest software-as-a-service (SaaS) provider of Consumer Online Backup solutions, SwapDrive (now part of Symantec’s Norton Data Services business unit) serves 13.5 million active users and manages more than 68 petabytes of data. Symantec acquired SwapDrive in 2008, but even before the acquisition, SwapDrive relied on Symantec storage management and server clustering technologies to:

  • Reduce hardware costs by up to 80 percent.
  • Minimize downtime for customers.
  • Help IT staff manage ever-accelerating data growth.
