The estimate of current requirements might be spot on, but the estimate for how the requirements will grow over time might be off base. This could mean the workload performs fine on the hardware purchased for it for a year or two, but that over time things get slow as the workload requirements increase.
In a perfect world, IT pros correctly estimate the workload of a particular server over the course of its projected lifetime. When they purchase the hardware for that workload, the workload grows into the hardware until it fits like a glove.
Unfortunately, when most workload estimates bump up against reality, they are found wanting. For example, the estimate of current requirements might be spot on, but the estimate for how the requirements will grow over time might be off base. This could mean the workload performs fine on the hardware purchased for it for a year or two, but that over time things get slow as the workload requirements increase.
There are also problems around estimates of the amount of time a workload will be in service. As many IT pros are aware, servers running Windows Server 2003 are still regularly being used--years after the people who initially implemented the servers assumed they would have been retired. When hardware outlasts its planned lifespan, the original capacity requirement estimates won’t even be in the same ballpark.
There’s also the issue of managers who assume that an IT pro has overestimated requirements, so they pare back the hardware. This action often means that the hardware that a workload runs on is underpowered from the start, leading to an experience that is less than optimal for everyone.
One of the huge value propositions of converged architecture is that it is, by nature, expandable. Should the current workload reach or exceed capacity, it’s a simple matter of expanding out the converged architecture system to meet that need. This is far better than purchasing an entire replacement system, something that is often necessary when capacity requirements are exceeded.
Converged architecture systems allow a workload to grow. As workload demands increase, the converged architecture system can be expanded to meet those needs--something that isn’t possible with traditional hardware deployments.
Underwritten by HPE
Part of HPE’s Power of One strategy, HPE Converged Architecture 700 delivers infrastructure as one integrated stack. HPE Converged Architecture 700 delivers proven, repeatable building blocks of infrastructure maintained by one management platform (HPE OneView), built and delivered exclusively by qualified HPE Channel Partners. This methodology saves considerable time and resources, compared to the do-it-yourself (DIY) approach.
Based on a complete HPE stack consisting of HPE BladeSystem with Intel® Xeon® E5 v3-based HPE ProLiant BL460c Gen9 blades, HPE 3PAR StoreServ all-flash storage, HPE Networking, and HPE OneView infrastructure management software, the HPE Converged Architecture 700 can be easily modified to fit within your existing IT environment.
