vSphere ESXi 4 upgrade problem

After new release of ESXi 4 update 1 I have had one of servers with famous "Unsupported boot partition..." problem. Of course, there was Windows 7 and vSphere client problem also...there was alternate solution to make client works under 7, I tested it but it wasn't so great. It works, but not as it should be working...with this update that problem is solved...you can now use vSphere client normally under 7 but not all of features. At least I can't...remote console view from client doesn't work.
For upgrade I used Host update utility which comes with client installation...it went OK except that update utility crashes under 7 at 80% of upgrade process which made me go insane :)...but, everything was OK because upgrade process was already copied all files to server and server himself just finished upgrade.
So, be aware of vSphere components and Win 7...certainly, for some time there could be "little" problems...

NSX ALB LetsEncrypt with DNS-01 challenge - BIND example

    In some of my previous posts, mentioned here LetsEncrypt script integration and Script parameter usage , I explained how useful it can be for NSX advanced load balancing solutions to utilise this kind of approach for free and automatic certificate manipulation, especially in environments with large number of web services inside. This approach utilises HTTP-01 based challenge with LetsEncrypt systems and L7 HTTP/S virtual services on NSX ALB side.     Now, from some time ago there is enhancement in this area, developed by official Avi Networks devops page, in terms of using DNS-01 challenge also. I tried on-prem option using Bind DNS as server which works very well.     Steps are pretty much similar to HTTP-01 option, which can be summarised as following:      - Create L7 virtual service with publicly available FQDN - certificates resolved can be in both options RSA or ECDSA, as configured during creation;        - Do...

VMware SD WAN - multiple locations - LAN IP address space overlapping with NAT

Image
     Different scenarios are possible in terms of routing, NAT-ing and IP overlapping setups using VMware Velocloud SD WAN technology in Customer environments.      Recently I had an PoC with my Customer for the on-prem option with this VMware solution, where different use cases were interesting to show and demonstrate - one of them is something I would like to share and it relates to possibility of LAN-side NAT on Edge (branch) locations, with purpose to have IP overlapped on these setups. Next picture is showing typical Hub&Spoke setup where it can be possible to make this type of configuration: Picture 1. VMware SD WAN lab on-prem environment     Basically thing which needs to be accomplished is appropriate NAT solution for LANs on every branch Edge which are and needs to be the same (192.168.1.0/24 in this example) - as it is shown on Picture 1.      Honestly speaking, NAT is not one of so powerful things insi...

NSX-T Layer 2 bridging - scenarios & use cases

Image
     Layer 2 bridging is very useful feature of NSX-T, which provides connection to a VLAN backed port group or a device, such as a gateway, that resides outside of NSX-T DC environment. Useful scenarios, among others, are: Workload migration from VLAN-backed to NSX overlay segment, NSX-V to NSX-T migration in Customer environments, Security features leverage using NSX-T Gateway firewall etc. L2 bridging feature requires usage of Edge clusters and Edge Bridge profiles.      Deployments should consider different options, with most important scenarios, for implementation below (this covers Edge VM deployment option as typical use case): Edge VM on VSS portgroup  --> promiscuous and forged transmit on portgroup REQUIRED / ESXi host (with Edge VM) command " esxcli system settings advanced set -o /Net/ReversePathFwdCheckPromisc -i 1 " REQUIRED / Active and Standby Edge VMs should be on different hosts, Edge VM on VDS 6.6 (or later) portgroup  -->...
