  • [ACP-DC Training#11] Loop Prevention and LAG Implementation

    Data center design involves multiple layers of redundancy, extending from server NIC cards to uplinks and switches. While this redundancy is essential, it simultaneously increases the risk of network loops, broadcast storms, and network outages. Today, we will learn key technologies to prevent these risks and build high-performance, redundant L2 data centers. 1. Structure of a Collapsed Core L2 Data Center A data center is…

  • [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 #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…

  • [ACSA Education #30] Link Aggregation

    Switches must provide connections to many devices located on various VLANs. All traffic generated here communicates with each other by sharing links between switches. Therefore, multiple links are sometimes connected between switches to enhance resilience. However, this does not increase the bandwidth of the connection between the two switches. Even if two links are connected, only one of them…
