Sometimes a hardware-defined traditional data center offers protection from software costs when licenses are based on physical assets. For example, a client was surprised when a software manufacturer updated their policy to include every physical asset in their cluster. The results of the policy were to buy more licenses or build isolated environments. There was also ambiguity around interpretation of the policy and meeting compliance. The end result was avoiding virtualization to create an environment that would limit the expense of the licenses.
One of the biggest benefits is the ability to use the latest technology as soon as it’s available whether it’s network, compute or storage. The industry is moving fast and some customers want to incorporate the latest products that accelerate performance. They also want the freedom to enhance one layer without replacing the others.
Evolution is occurring around performance and high availability especially with organizations who have high-transactional requirements. New product releases in server memory technology have increased transactional processing power by hundreds of thousands. So, the focus is shifting from storage to the server infrastructure. With high availability however, the focus is on storage. There is a growing need for a second copy of data on a second target to enable availability groups, stretch clusters and fault tolerance.
Popular today are the ready nodes or servers designed to be compliant with hypervisor converged requirements. A customer buys these nodes and they have the correct, integrated components. There is no fancy, self-installing script, but lower-cost economics drive this market.
