When managing a converged architecture system, you need to have systems administration techniques that can scale in the same manner that you scale the converged architecture system itself. This means that rather than leveraging techniques that you might use to manage a small number of servers, such as Remote Desktop Connection or direct sign-on to console, you should transition to techniques that allow you to automate as much as possible, using tools including Microsoft’s PowerShell.
One of the big benefits of converged architecture is that it allows an organization to reduce the number of physical computers deployed, as a converged architecture system allows many workloads to be consolidated down to a single chassis. This is especially true when the converged architecture system is a virtualization host.
With that said, an HPE Converged Architecture deployment, for example, can host up to 9,000 virtual machines. This many virtual machines hosted in a single place presents challenges to traditional systems administration practice. If you are responsible for managing those virtual machines and you need to perform a task on all 9,000--such as configuring a specific setting in response to a security bulletin—efficiency is key.
While you could sign on to each virtual machine and configure the setting, this would take a few minutes per virtual machine. Over 9,000 virtual machines, a task that takes 3 minutes on each will take a total of 450 hours. If you come up with a way to automate the task, it might take less than an hour.
The trick to managing converged architecture is understanding that you need to automate every task that you repeat more than a couple of times. Every task that you automate is one that you have to spend less time doing manually in future. You’ll be able to scale up your reach as a server administrator in the same way that converged architecture allows you to scale up the workloads your organization hosts.

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 HP stack consisting of HP BladeSystem with Intel® Xeon® E5 v3-based HP ProLiant BL460c Gen9 blades, HP 3PAR StoreServ all-flash storage, HP Networking, and HP OneView infrastructure management software, the HP Converged Architecture 700 can be easily modified to fit within your existing IT environment.
