I’m in the process of moving my ZFS pool of 6 x 4TB disks to a new server,  so taking a moment to re-design. Design ZFS supports redundant data by the concept of a ‘vDEV’.    Each vDEV is a redundant combination of 2 or more disks.  vDEV’s can then be connected together for larger capacity. vDEV Mirror 2 disks written with identical information.   Can … Continue reading ZFS Pool design

References vSphere / ESXi homelab setup   ( Existing lab setup ) Logical Switch setup on NSX   ( Earlier post on setting up Logical switches ) Intro This post continues my studying of basic NSX concepts in preparation for my VCAP6-NV. I’ll try and cover some answers I’ve found to some of my mis-conceptions along the way, and finally run a few labs. As a review … Continue reading NSX lab North/South Routing options

Introduction It’s relatively easy to enable vSAN on our Nested lab,  so let’s  take a short detour. My previous posting on Nested ESX setup is here. And the physical network setup is here. I originally had setup my nested lab with vSAN but immediately got very low disk IO performance of about 2 IOPS, so I switched to NFS storage.    Even NFS had sub-par … Continue reading Adding VSAN to my Nested ESXi lab

This part continues to build out NSX on top of the Nested ESX cluster created in the last part ESX/NSX nested lab – Part I. Part I included some basic NSX setup for convenience such as. NSX Manager installed from OVF, and linked to vCenter. Physical network ESXi uplinks included allowed vLAN 100 for vxlan. distributed switch set to allow Jumbo 9000 MTU,  (> 1600 MTU … Continue reading ESX/NSX nested lab – Part II
