  • [ACP-DC Training #4] Building a Data Center Network

    We have finally successfully completed the first step of building the data center network. Over the past period, we have understood the basic overview of the data center network and secured sufficient important resources and materials, namely the necessary products (hardware) and technologies (protocols). This process can be likened to an architect understanding blueprints and preparing the required materials before constructing a building. From now on, we will actually utilize these prepared resources to…

  • [ACP-DC Training #3] Data Center Technology

    Last time, we discussed the robust hardware products of data centers. While physical equipment such as servers, storage, and switches are important, what truly makes a data center 'smart' are the various technologies running on top of this hardware. Simply put, data center technology refers to the various protocols configured on switches. These protocols efficiently [manage] the applications and workflows that are the core of the data center…

  • [APSC Training #7] Aruba Central Device Management Method (2) – Site / Label

    In the previous post, we looked at the device management methods provided by Aruba Central. We examined the Group method among the three options: Group, Site, and Label. This time, we will explore the remaining two methods: Site and Label. Site: A Site refers to a physical location where a series of devices are installed, such as a campus, branch, or place. A site is…

  • [APSC Training #6] Aruba Central Device Management Method (1) – Group

    Once you have onboarded devices and mapped subscriptions to Aruba Central, you need to manage the devices starting from their configuration. To manage devices more efficiently and generate reports, Aruba Central manages them in three ways. By appropriately utilizing these three methods, you can manage and monitor the devices and endpoints connected to Central. From the left-hand menu of the Network Structure page in Central…

  • [APSC Training #5] Aruba Central Subscription Management
