New Release: Introducing Veritas Cluster Server and Veritas Dynamic Multi-Pathing for VMware
Mike Reynolds PMM | 04 Sep 2012 | 3 comments

 

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...

Top Five Methods to Bullet Proof Your Disaster Recovery Plans
Mike Reynolds PMM | 19 Jul 2012 | 1 comment

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...

Don't be that guy
Eric.Hennessey | 07 May 2012 | 1 comment

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...

Out: Clustering. In: Application Management
Eric.Hennessey | 18 Apr 2012 | 0 comments

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...

Stop the guessing game with your mission-critical applications in VMware
Raissa_T | 16 Apr 2012 | 0 comments

IT organizations have embraced virtualization as a way to cut costs and make their data centers more agile to respond to business needs.  However, application visibility inside VMware HA is nascent and can lead to disastrous failures.  Listen to this podcast, as Lorenzo Galelli, Sr Principal Technical Product Manager at Symantec, explains how you can confidently gain visibility and control of mission-critical applications inside VMware.

Everything you think you know about clustering is wrong: Busting the myths of unreliability and complexity
Eric.Hennessey | 10 Apr 2012 | 1 comment

 

In my last post I mentioned a few common misconceptions about HA clustering that I'd be debunking; namely that it's unreliable, complex, and expensive. There are others that we'll get to in later posts, but for this one I want to tackle the myths of unreliability and complexity, since they kind of go hand-in-hand.
 
The vast majority of our customers using Veritas Cluster Server (VCS) for high availability have been using it for quite some time and are completely happy with it. But we do hear from time to time from customers who say they've used HA clustering in the past - either VCS or Brand X - and stopped using it because it "broke". Frankly, this reaction baffles me. As an IT guy who's been in the business for - well, let's just say a long time, OK? - I learned early on that if something...

Everything you think you know about clustering is wrong
Eric.Hennessey | 06 Apr 2012 | 0 comments

We're making some pretty big changes in how we deliver high availability and disaster recovery, and to do that, we have to change how we look at HA & DR. But in order to do that, we first need to debunk a few myths about clustering that seem to have crept into a lot of people's heads over the years.

 

This is the first in a series of posts I'll be putting up here at Symantec Connect over the coming week or so in which I'll lay out some common misconceptions of HA clustering and explain why they're wrong. Here's an example of what some people believe about clustering and which I'll refute over the coming days:
  • Clustering is unreliable
  • Clustering is too complex
  • Clustering is expensive
Sure, like any other myth these have...
