What is Micro-Segmentation? When it comes to SDN micro-segmentation is one of the biggest use cases/features that it has to offer. But what is micro-segmentation? In its purest form, Micro-Segmentation is a security technique that further isolates workloads/segments, allowing for finer-grained security controls to be applied. Traditionally, network

Within this post, we will show you how to build a virtualized NSX SDN lab. Our lab will be loosely based around the VMware NFV 2.0.1 Reference Architecture. For those of you who haven't worked with the VMware NFV reference architecture, it consists of a set

What is iSCSI? iSCSI (internet SCSI), is an Internet Protocol (IP)-based area storage networking standard for linking data storage facilities. It provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network.[1] Unlike FC SAN which requires dedicated hardware (FC HBA, FC switch, etc.

What is an ASN? An autonomous system number (ASN) is a unique number, assigned by IANA that is available globally to identify an autonomous system and which enables that system to exchange exterior routing information with other neighboring autonomous systems. [1] Figure 1 : BGP/ASN Example ASN Types There are

MTU The MTU is the maximum payload length for a particular transmission media. For example, the MTU for Ethernet is typically 1500 bytes. (The maximum packet length for Ethernet is typically 1518 bytes, but that includes 14 bytes of Ethernet header and 4 bytes of CRC, leaving 1500 bytes of

Introduction HPEs - Virtual Connect FlexFabric networking, can take a while to wrap your head around. So I thought I would take a moment to explain what HPE Virtual Connect is, and also share some knowledge and also resources that you may find useful. What is Virtual Connect? Virtual Connect

Introduction Within this short article, we will answer the question: What is a FlexibleLOM? First of all, What is a LOM? LOM LOM (LAN on motherboard) refers to a chip or chipset capable of network connections that have been embedded directly on the motherboard of a desktop, workstation or server.

Introduction This article provides a summary to some of the key points around vSAN network design. For full details around vSAN network design please review https://storagehub.vmware.com/export_to_pdf/vmware-r-vsan-tm-network-design. What is vSAN? vSAN is a hypervisor-converged, software-defined storage solution for the software-defined data centre. It is

Introduction In our previous posts , we installed the management plane aka VSD, and also the controller aka VSC. We will now install the VRS. VRS is the virtual switch that replaces OVS within each of the compute nodes. This is achieved via an RPM install on each of the nodes.
