AOS-CX

  • Putting a container image on a switch

    Starting with AOS-CX version 10.13, a new feature called the Feature Pack has been introduced. Advanced features can now be accessed through an additional software license subscription called a Feature Pack. There are two types of Feature Packs: Advanced and Premium. The Premium license is required to enable the NAT and IPSec functions of the CX 10000 switch. Other Feature Pack features are…

  • [acp-dc training#10] vsx (2)

    In the previous post, we explored VSX, the virtualization technology of HPE Aruba Networking AOS-CX switches. We explained the components of VSX, the differences from VSF, and its advantages. Today, we will cover the practical aspects. We will examine how to utilize VSX in practice, such as live software upgrades and technologies like Split Brain. VSX Control Plane Separation and Software Update Control Plane…

  • [ACP-DC Training#9] VSX (1)

    Today, the demand for network availability is ceaseless. Customers require networks that operate 24 hours a day, 365 days a year, and HPE’s VSX technology offers a solution to this problem. HPE Aruba Networking’s VSX technology is a virtualization technology for data center and core switches running on the AOS-CX operating system. This solution enables switches in critical areas to function as if they were a single virtualized…

  • [ACP-DC Training#8] 2-Tier Design for Small Data Centers

    Layer 2 two-tier designs are simple to deploy, operate, and troubleshoot because they utilize existing traditional protocols. They can be managed without specialized knowledge of overlay protocols or complex designs. This architecture is suitable for small to medium-sized data centers, but in larger environments, it can also be implemented at the data center POD level. In a two-tier data center, host information is traditional bridge…

  • [ACP-DC Training#7] Deploying Data Center Switches

    Deploying data center switches may look similar to installing campus switches, but there are unique aspects specific to data centers. In particular, data center switches often undergo a 'staging' process to prepare their configuration before being brought into the field. Today, we will take a closer look at what switch staging is and the two main provisioning methods. Switch Provisioning: The Challenge…

  • [ACP-DC Training #6] DCI and OOBM

    In the last post, we examined various data center network designs. We explained the characteristics of each design, along with their advantages, disadvantages, and architectural changes. This time, we will look at Data Center Interconnect (DCI), which connects data centers, and OOBM, which is a management network. Data Center Interconnect (DCI): A technology that connects multiple data centers. Everyone, it is common for customers to operate multiple data centers. These data centers are one…

  • [ACP-DC Training #5] Data Center Network Architecture

    Today, I would like to discuss data center network architecture. When designing a data center, many factors are considered, such as its purpose, size, and future scalability. The architecture is then designed to align with these factors, taking into account available budget and time. Let's explore the different architectures available, as well as the characteristics, advantages, and disadvantages of each. 1-Tier Design 1-Tier…

  • [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…

  • [ACP-DC Training #2] DCN Products and Specialized Technologies

    Continuing from last time, this time we will cover HPE Aruba Networking DCN products and technologies related to data center network deployment. As this module serves as the starting point of the process, you must be able to select appropriate products and deploy them in a design suitable for your data center. We will examine various HPE Aruba Networking products and explain the technologies required for DCN. Inflexible, outdated existing infrastructure…
