More and more information is becoming readily available to companies and they are leveraging it to advance business and give consumers what they want. This practice known as “big data” has the potential to yield big opportunities, as well as its share of management headaches if not approached strategically. In the latest CIO Digest article “Big Data Without Big Headaches,” Symantec lays out three basic strategies that IT leaders should consider when leveraging big data. Getting the strategies right will enable companies to make effective decisions and realize the business value of big data. But get them wrong, you can end up with incomplete information and introduce a New Coke. With these data-driven strategies in place, companies like Asia Pacific Telecom, Telefonica de Espana, and Teradata have seen results in both financial and operational performance. Indeed, embracing big data doesn’t have to come with big headaches. To get more in-depth...

Windows 8 has been released... OK, so I'm not actually that excited about Windows 8 (I'm a Mac user and I like my screen sharp and finger print free).  But as usual it was accompanied by a new version of Microsoft's server OS - 2012 and that does excite me.
 
Yes 2012 has got a load of new functionality, but these 'cool new features' aren't the interesting bits, it's what's been in there for a while that's really exciting.  There are a few components in Windows 2012 that have hit version 3.0 and that's a big deal, one of those is Hyper-V.  What this really means is Microsoft's hypervisor platform has passed a milestone in maturity.  Typically when Microsoft brings a new technology to market it takes a few versions of fine tuning to really hit the mark.  During this time, some early adopters will use it for production workloads, but the majority of large enterprises will confine it to...

Cloud computing has long been a buzz word in the IT sector. A seemingly fitting definition of cloud is “a model for enabling convenient, on demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. Many organisations have cautiously been dipping their toes in the public cloud market. Many applications can be seamlessly delivered through public clouds which alleviate the need to on premise servers and reduce the capex costs involved with hosting these services on premise.  Public clouds offer the benefit of utilizing someone else’s  infrastructure to run IT workloads on a pay as you go basis thus reducing your capex costs. Private clouds are different since they leverage cloud technology and ultimately reduce overall opex costs and improve business agility. Many organisations particularly in the financial sector simply wont use public clouds for their mission critical...

The modern organization is highly dependent on information technology, simultaneously and quite unintentionally, information technology has introduced new exposures which have deceptively seeped into every layer of the financial organization.  The likelihood that an organization will experience a catastrophic loss from an IT-service interruption caused by an IT issue is far greater than an interruption coming from some disaster or ‘black swan’ event.  Still, the key to survival is allocating the appropriate amount of resources to the “right” risks; while that may include planning contingencies for a worse-case scenario, to be rational about risk more guidance regarding the investment tradeoffs that mitigate risk.

The “Big Question” is how to optimize scarce resources today, to achieve the greatest reduction in future losses.  The Big Question two components: (1) which risks are the serious ones and...

Recently one of my customers had a series of outages in the Communications between their buildings. The upshot of this is because of the way they had deployed their clusters they weren’t protected against their cluster nodes losing communications between each other. I have seen mixed experiences from my customers in terms of split brain issues (split brain is when all nodes in a cluster begin writing in an uncoordinated fashion to shared storage as they each believe they are the last node in the cluster)

I have seen customers running Campus Clusters with no split brain protection and have yet to see any problems. I have also seen other customers who go belt and braces using IO fencing which is built into VERITAS cluster server. Some have issues due to the way they handle the IO fencing devices as they are often not understood. So what's it all about then? it’s pretty simple.

For a cluster to work there needs to be a communication system between the...

Operational risk is everywhere in the business environment, every decision has its share of uncertainty.  Nothing is a sure thing, yet we when we make important decision we certainly want to “keep the odds in our favor”.  I have often heard the terms like ‘risk appetite’, ‘risk tolerance’, or ‘risk aversion’ used in reference to making forward-looking choices about operational risk as if we can rationally and effectively manage risk based on our subjective feelings.  These terms, however, provide little guidance and position risk-management in the domain of oracles and soothsayers.  Business is not a game of chance based on our subjective ‘feelings’ regarding operational risk. 

The stakes are too high relative to operational risk to leave it to subjective guesses or ‘gut’...

The benefits of data center consolidation are apparent; they save millions of dollars and improve the overall quality of service.  It is easy to see that too many data centers adds unnecessary costs, it chips away at manageability, increases complexity and contributes to a number of operating inefficiencies.  Realizing the economic benefits of data center consolidation can be elusive, the challenge is to circumvent the potential pitfalls that complicated the transformation process.

Data center consolidations involve much more than just moving servers or data from one location into another.  Data centers have become a conglomeration of disparate technologies running on combination of virtual platforms, physical platforms, and clustered platforms that operate an assortment of systems and access a range of data-tiers that are stored on multiple arrays from a whole host of hardware vendors.  

In addition to the...
