|DSCP||The Layer 3 Differentiated Services Code Point (DSCP) detects packets based on their DSCP values. CoS is always applied to the data packet irrespective of the trusted mode.NSX-T trusts the DSCP setting applied by a virtual machine or modifying and setting the DSCP value at the logical switch level. In each case, the DSCP value is propagated to the outer IP header of encapsulated frames. This enables the external physical network to prioritize the traffic based on the DSCP setting on the external header. When DSCP is in the trusted mode, the DSCP value is copied from the inner header. When in the untrusted mode, the DSCP value is not preserved for the inner header.|

|IQN||ISCSI Qualified Name. iSCSI Naming Conventions. iSCSI uses a special unique name to identify an iSCSI node, either target or initiator. This name is similar to the WorldWide Name (WWN) associated with Fibre Channel devices and is used as a way to universally identify the node. iSCSI names are formatted in two different ways. The most common is the IQN format. For more details on iSCSI naming requirements and string profiles, see RFC 3721 and RFC 3722 on the IETF Web site. iSCSI Qualified Name (IQN) Format.

|MTU|| Maximum Transmission Unit. Change the size of
the maximum transmission unit (MTU) on a vSphere Standard Switch to improve
the networking efficiency by increasing the amount of payload data
transmitted with a single packet, that is, enabling jumbo frames. |
Procedure: 1. In the vSphere Web Client, navigate to the host. 2. On the Manage tab, click Networking, and select Virtual switches.
3. Select a standard switch from the table and click Edit settings. 4. Change the MTU (bytes) value for the standard switch.
You can enable jumbo frames by setting MTU (bytes) to a number greater than 1500. You cannot set an MTU size greater than 9000 bytes.
5. Click OK.

|NUMA||Non Uniform Memory Access|

|POD||Point of Delivery. Small set of common building blocks called pods. In the Software-Defined Data Center (SDDC) there are several types of workloads. There are workloads needed to instantiate and support the underlying SDDC infrastructure itself. For example, in order to create and manage VMs, I first need to have a Platform Service Controller, a vCenter Server, and one or more ESXi hosts. Before I can create logical switches and transport zones, I need to have an NSX Manager and three NSX Controllers. You get the idea. The SDDC is built on-top of an infrastructure which includes a number of VMs and services that are needed to instantiate that infrastructure. In the VMware Validated Design these SDDC “infrastructure” components are referred to as “management” components, and we have a special place in the SDDC where we run these components – this place is called the Management POD. Each validated design starts with these three basic PODs – the Management POD, the Edge POD and one or more Compute PODs. These PODs interconnect to instantiate the SDDC. Things like redundancy, availability, scalability, load balancing, etc. are all designed at the POD level. As your business grows, you simply add additional PODs in order to scale out the SDDC.|
