Featured: New Release: Get the Private Cloud you Want From the Infrastructure You’ve Got
DLamorena | 03 Oct 2011 | 3 comments

Symantec today announced a major refresh to its Storage and Availability Management portfolio to help customers build the private cloud they want by transforming their existing infrastructure. Symantec’s high availability solutions will enable users to architect resilient private clouds with fast local or global recovery of complete business services and data replication across any distance to meet their recovery time/point objectives. Symantec can orchestrate the recovery of a business service, even if its components (various databases, application servers, and web servers) run on different operating systems or virtualization technologies. 

As more IT organizations move to the cloud, Symantec’s new storage management offerings will also help IT organizations manage and deliver elastic, resilient storage for cloud workloads by providing the ability to scale storage capacity up or down while applications remain online and reducing the storage footprint...

Featured: Virtual Business Services: High Availability for Complex Applications
Eric.Hennessey | 29 Sep 2011 | 1 comment
Things just aren't as simple as they used to be. There was a time when we could achieve nearly all of our uptime goals just by clustering our backend database servers and maybe a handful of other application servers. There was very little of that weird virtualization voodoo going on, and all our important 
applications ran on physical servers.
 
Well, times have changed. Not only are a larger share of our applications considered mission critical, but our service level agreement expectations are much higher and we're under pressure to virtualize more applications in order to realize greater cost savings in the data center. To further complicate things, those applications have grown more complex with more moving parts. For those of us concerned with high availability and disaster recovery, this has presented some interesting challenges.
 
Consider, for example, an online...

Don't be that guy
Eric.Hennessey | 03 May 2012 | 0 comments

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 | 13 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 | 05 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...

Converged Infrastructure: Tabasco sauce not included
Eric.Hennessey | 14 Feb 2012 | 0 comments

 

I was fortunate enough during my many years in the military to have been assigned to fixed-base communications units, meaning it was only on rare occasions that I had to choke down those infamous MRE (meal, ready to eat) rations that the US military hands out to personnel deployed in the field. For those unfamiliar with them, an MRE is a big packet containing a full meal for one, typically with items like corned beef hash, freeze-dried fruit, crackers & jelly, and maybe an oatmeal cookie.
 
When MREs are handed out at meal time, everyone takes a look at what their particular packet contains and the inevitable trading begins: "Anyone wanna trade with me for my corned beef hash?" or "Hey! Did anybody get chicken ala king? I'll give you my tuna with noodles!" In the end, though, everyone just put Tabasco sauce on everything to make it edible, so it didn't matter what they got in the first place.
