Converged architecture hosts are good for a lot of things—infrastructure roles are not one of them.
Converged architecture is well-suited for hosting applications like Exchange, SharePoint, SQL Server, and virtualization because these workloads tend to have substantial resource requirements. Converged architecture is also an especially good choice for these kinds of workloads because you can purchase CA systems with these workloads in mind. For example, you can buy a converged architecture system that is designed specifically to run Exchange; the converged architecture system will be more efficient because the hardware utilization profile of Exchange is a known entity.
This is not the case for on-premise infrastructure roles such as DNS servers, DHCP servers, routing and remote access servers, and domain controllers. Each of these is very important, of course—you couldn’t run Exchange, SharePoint, SQL Server, virtualization or a host of other things without them, but they rarely require excessive hardware capacity—at least, not to the extent that platforms like Exchange, SharePoint and SQL Server do. There are rare cases when an organization has more than, say, 50,000 clients and the number of requests to infrastructure roles like domain controller necessitates a different approach to hardware. But these are the exceptions rather than the rule.
In many organizations, infrastructure roles are hosted as virtual machines. There are converged architecture configurations suited to the virtual machine hosting role, so this could be a way for infrastructure roles to be hosted on converged architecture hosts. But organizations tend to be a little cautious about hosting critical infrastructure roles in virtual machines: It adds another dependency to the mix, and most admins want to minimize the number of dependencies required to host critical roles.
For most organizations it makes sense to have some roles, like infrastructure roles, hosted on off-the-shelf hardware and to use converged architecture for specific business-critical roles like Exchange, SharePoint, SQL Server and virtualization.
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.
