Virtualization is everywhere, but IT organizations are still looking for ways to cut costs.  One way to do that, is to…  virtualize even more applications!  However, the easy stuff has been done.  File and print servers, cafeteria menus and the company picnic blog have been virtualized.  The next step is to move up the chain and virtualize business and mission critical applications.  But the risks of virtualization are still there.  How do I monitor and protect my application and business services in the event of a failure, or even a site wide disaster?  What happens to the performance or availability of my data when a path connecting a virtual machine to the storage fails?  These are the roadblocks that are preventing IT organizations from virtualizing more of their business critical services and applications.  The good news is Symantec can help!  

Symantec is announcing a new version of...

Do you have control over your virtualized environment?
It is imperative that the Lotus Renault GP F1 Team has 24x7 availability to all of its applications. If the team lost access to IT during a race, it would be driving blind. To ensure that doesn’t happen, the Lotus F1 team turned to its long-standing technology partner, Symantec. The team implemented Symantec ApplicationHA to gain visibility into its VMware environment. ApplicationHA provides the Lotus F1 team with granular control of all its applications, delivering 99.99% availability. For more information about how the Lotus F1 Team is using ApplicationHA in its VMware environment check out this video: http://bit.ly/O3ixps.

Disasters happen.  In fact, according to the Munchener Ruckversicherungs-Gesellschaft, Geo Risks Research, 355 events, from floods to tornados to tsunamis and earthquakes occurred in 2011.  IT organizations need protection from such horrific events, but also those that are more common place, for instance power outages and equipment failures.  

Here are a few interesting statistics from the latest Symantec State of the Data Center report (available later this year):

  • 70% of organizations experience downtime from power failure (11.3 hours per outage)
  • 63% experience cyber attacks (52.7 hours per outage)
  • 26% conducted a power outage and failure impact assessment
  • Median downtime per outage in the last 12 months was 5 hours
  • Organizations experienced an average of 4 downtime incidents in the past 12 months

When most people hear the term "Disaster Recovery", they immediately think of data...

I have been working for Symantec for more years than I care to remember. I joined through the Veritas acquisition some 6 years ago. In that time the datacenter has changed incredibly, before joining Veritas I was a systems administrator, this was long before the concept of SANs were mainstream and most UNIX systems simply had direct attached storage. I think it’s fair to say that at some point over the past 10 years the datacenter began transitioning from physical to virtual and we at Symantec were very guilty of not adapting our solutions quickly enough. We went on selling our traditional clustering and storage management tools which while they have always been best of breed weren’t necessarily a good fit in virtual environments. Thankfully due to the strength of our portfolio our product team began to reinvest into adapting our solutions specifically into the virtual space. The upshot is now although there is still much development and innovation under way we have a...

Are you setting up Veritas Cluster Server in VMware vSphere?  Below is a technical guide to walk you through the process such as configuring Veritas Cluster Server clusters across ESX hosts and the compatibility of VCS with VMware HA. Check out the new Application Note available now.

Environment

Two ESXi Servers = Esxi1 and Esxi2

version of Esxi Servers = 5.0

Vcenter OS = Windows2008R2(64bit)

SAN = iscsi SAN attached on both Esxi Servers

HA and DRS = enabled

Application HA = 5.1 SP2

Application HA OS = rhel 5.6 (64bit)

Application name = sshd

Problem

I was facing the subjected error while configuring the Application under Symantec Application  HA. See the below snap as a reference:

Solution

There may be other culprits but in my case there were two things which was occuring.

1.) initially I was trying to configure Symantec Application HA on a OS which was configured as vmware FT. On the vmware FT this will not be applicable as per my understanding because the status is same of both VMs as primary VM and the partner VM are being replicated...

A funny thing happened the other day when I went to one of my favorite sites to look up a word...I saw the above message, but looking at the redirect URL, it says "failover-namechangedtoprotecttheinnocent.com". Now, far be it from me to be correcting the vocabulary of a site whose stock in trade is word definitions, but in the high availability biz, that is NOT what we mean by "failover". A failover is when you have a service under HA cluster control, and in the event of a failure, that service is relocated to another server in the cluster. In its entirety.

Clearly there was some attempt made at protecting the service, otherwise my browser would have just thrown an error saying the site wasn't available. But it's just as clear that protection wasn't extended to the entire business service. We introduced Virtual Business Services to Veritas Cluster...

I've been blogging over the past couple of weeks under the theme "Everything you think you know about clustering is wrong". It's sort of a tongue-in-cheek theme, but the misconceptions I was trying to dispel are real and held by enough people that I felt they were worth addressing. But now I want to shift gears a little bit.

In my last post, I mentioned how a lot of people can't seem to break out of the late-1990s mindset of 2-node active/passive failover HA:

While large clusters meant we no longer needed two nodes for every critical application, many people's mindsets were still stuck in 1997 and they continued to view HA clustering in a 2-node, active/passive context.

To be sure, that's definitely not the case with all of our customers, especially...
