The biggest driver for adoption of Hadoop is its promise of unlocking value from an enterprise’s vast data store. Use cases that show incremental revenue from data analysis are very well publicized.  Every organization strives to achieve that and wants to leverage the power of data analytics to drive its revenues. Promises aside, Hadoop storage has severe issues that calls  into question its place in the enterprise datacenter.

  1. Increased storage and server sprawl – Hadoop cluster is built  with numerous commodity hosts, each with its own direct attached storage. Just when datacenter architects have spent considerable time and resources consolidating their datacenters and reducing footprint through server consolidation, virtualization and private cloud,  Hadoop requires them to build out a massively parallel system with hundreds or even thousands of compute nodes. Managing these numerous nodes and keeping them up to date with right...

Unstructured data growth is exploding. According to Gartner, the growth of data is 40% to 60%, but for unstructured data in the enterprise, the growth rate can be up to 80% (2011). With this challenge in mind and after months of collaboration, NetApp and Symantec have developed Symantec Data Insight - a solution that integrates with NetApp storage systems, among others, to discover and collect data activity and permissions in unstructured data in order to improve an organization's data governance objectives. Data Insight is also integrated into Symantec Data Loss Prevention enabling organizations to discover, monitor and protect confidential information residing in CIFS and NFS file shares on NetApp storage systems.

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 a common...
