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...

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.

A couple days ago, I blogged about the related myths of complexity and unreliability regarding high availability (HA) clustering. Today I want to spend a little time on the myth that clustering is expensive.
 
Early high availability clustering was as simple as it was primitive. Shared  storage was generally limited to two nodes via dual-attached SCSI disks and  communication between nodes typically consisted of each node just pinging the other periodically to check its state. If the standby node decided the active node was dead, it would respond to that failure by firing local copies of the  failed node's startup scripts to restart applications that had been running there.
 
But SAN and NAS technologies which allowed many more nodes to share...

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...

I'm glad to announce that Symantec is named a LEADER in the 2012 Gartner Magic Quadrant for Storage Resource Management. We moved the needle in both execution and vision. Gartner viewed the introduction of Veritas Operations Manager (VOM) Advanced as a positive move for Symantec and applauds VOM Advanced for providing a holistic view of storage and server environments. You can view the full report here.

VOM Advanced is a premium version of Veritas Operations Manager, a comprehensive management platform that helps you optimize data center assets, ensure availability, scale operations and increase storage utilization. VOM Advanced supports agentless deployment, provides chargeback...

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 their origins in someone's actual experience, but just like the mythology...

Before virtualizing mission-critical applications, enterprises must be confident their virtualization solution provides visibility, availability, failover and load balancing. In VMware environments, these advanced features haven't been available with VMware native multi-pathing tool. The new Dynamic Multi-Pathing for VMware offers the flexibility of multi-pathing to any VMware guest VM, and supports nearly 70% of storage arrays.
