ESXi homelab help

Hello,

I have a Intel NUC at home which is great for learning ESXi (6.7) and also running running my pfSense firewall (for layer 3 routing and Internet access) and some other VMs (monitoring etc).

The Host only has 3 x 1GB but this is fine for home I’m not too bothered about network performance at this point. When I can afford it I will be getting 1 more and then buy a Vmug Advantage subscription to allow me to use vCenter.

The host goes into a Layer 2 Mikrotik switch where I have various VLANs for WiFi, my Servers, Management etc.

I have a couple of areas I want to play with 1 is iSCSI and the other is getting vMotion ready for when I add the 2nd host. I have been given a Synology DS218+ NAS which has 2 x 4TB drives, I was hoping of using it’s 1GB port for iSCSI and VM backups (I use ghettovcb) and also house some VMs on datastores on there. I guess I could use the spare port or use this for vMotion.

Here are my NICs:

vmnic0 = trunk to switch

vusb0 = WAN port to ISP router which pfSense uses

vusb1 = unused

I have this spare port which is currently a vSwitch called vSwitch-pfLAN, should I use this for vMotion and iScsi or can I use iScsi over vSwitch0 (trunk). As you can see I’m a little limited and wondered if it’s even possible?

I need to create a new VMKernel fpr vMotion, I guess I could use the spare NIC or add the service to the management port? What about iSCSI?

Thanks

  1. Please use iSCSI on the dedicated Port. Use vMotion on the default vSwitch with VMnetwork and Management. Please consider that your VM network performance could get really messed up when a VM is vMotioned because it will take much bandwidth.
    This setup is really far away from best practice, but it’s a home lab, so I think this solution fits your needs the best.

  2. Put the vMotion with the VM/management traffic. This is a lab and are you going to be vMotioning SQL servers or Exchange servers while under load? Probably not.

    I wouldn’t advise spending money on 10Gb equipment. Spend it in storage and memory instead. The 1Gb NICs for a lab is fine for a long time. Your NAS doesn’t have SSD from the looks. I would be surprised if it can actually use the full 1Gb for more than maybe a burst. Even with SSDs 1GB will be good.

    Then again collecting hardware can be a hobby of it’s own.
