                          VMware ESG vs DLR ESG DLR -        It’s always a VM. -        We use ESG for North-South. It means, going outside from datacenter towards the external network or internet. -        If you have logical switches in different transport zone, then you can use ESG. -        ESG is for different transport zone, but DLR is for same transport zone. -        It supports dynamic routing as well as static routing. -        It supports OSPF and BGP. -        It supports both the routing protocol at the same time. -        It is for centralized routing. -        Since it is a VM, so it can have maximum of 10 interfaces. -        On one interface, we can have maximum 200 sub-interfaces which will be connected as trunk interface. -        ESG has  internal interface  which connects with South. Means, it connects to DLR. (Transit Network). -        Physical router will be  Uplink interface . -        It’s a kernel module. -       

                                                VMware NSX Introduction IT organizations have gained significant benefits as a direct result of server virtualization. Server consolidation reduced physical complexity, increased operational efficiency and the ability to dynamically repurpose underlying resources to quickly and optimally meet the needs of increasingly dynamic business applications. VMware’s Software Defined Data Center (SDDC) architecture is now extending virtualization technologies across the entire physical data center infrastructure.  NSX for vSphere  is a key product in the SDDC architecture. With  NSX for vSphere , virtualization delivers for networking what it has already delivered for compute and storage. In much the same way that server virtualization programmatically creates, snapshots, deletes, and restores software-based virtual machines (VMs),  NSX for vSphere  network virtualization programmatically creates, snapshots, deletes, and restores software-

                                  Not able to register vRB with vRA 7.6 version During my upgrade of vRB, i had encountered with vRB registration with vRA. This is known issue as of now with vRB and VMware is aware as well. there is a fix for this. Getting error " Invalid data format " while registering with vRA. 1. SSH to vRB appliance and go to "/usr/local/tomcat/shared-lib" 2. check if any .jar files exist there or not. In my case, there was no .jar files located under this directory. 3. I got shared lib .jar files from VMware for vRB 7.6 version. 4. Once got the .jar files from VMware, follows below steps. If you need vRB 7.6 versions .jar files, comment me on this post, i will provide that. 5. ***** Take a snapshot of the vRBC appliance again ***** i. SSH to vRB appliance and run command "monit stop all" ii. Put all the jar files to "/usr/local/tomcat/shared-lib/" iii. R un command "monit start all" iv. Re-Register the
