Use rapid tables, enter in your wattage and hours per day, if you put in your power cost it will even give you a monthly and yearly bill. Just google “power cost calculator”

4 blades? Jesus those must be old. I thought 800w idle with 3 UCS b200 m3 blades in a UCS mini was bad…

I’m now running 3 dell r630’s with dual 10 core e5 v4, 384gb ddr4 and 8x 1.92tb SSDs and it’s under 400w idle with 12 or so VMs running

~550w Nexus 9k 48p 10g 6p 40g 3x dell r630, 2x 10c e5 2640 v4, 384gb ram, 1x 960gb nvme ssd and 5x 1.92tb sata SSDs

Though it may change soon… not for the better

Are Xeon v4 machines good today for long-term? by EpicEpyc in c/homelab@selfhosted.forum

I’ve got 8 dell r630’s, hp dl380 g9, and 2x 2u 4 node supermicro chassis all running e5 v4 CPUs in my lab. Still supported by the current build of VMware, they run great and are relatively power efficient. I do have 4 Xeon gold servers, however I havnt even fired them up because they aren’t much better than the v4’s (only v1 scalable) but I probably will eventually when VMware ups the hardware requirements.

I don’t know where you are at, but in most countries with eBay or probably anywhere else, buy the server barebones, or with really low spec components (low ram and even v3 CPU’s) and upgrade it yourself. I find this to be a lot cheaper than buying it prebuilt with identical specs.

For example, my dl380 g9 came with a single v3 Xeon, I bought a 12 core e5 2650 v4 for literally $4.79 shipped to my door. Flashed the new bios and I was off and running. I also can pickup as much ram as I want for ~$7 per 8gb ddr4 dimm or $12 for 16gb dimm on eBay all day long (us prices obviously but it still should be cheaper to buy low spec or barebones outside the Us and upgrade)

Best 2 node storage solution (alien.top)

My 24/7 homelab is currently running in a 3 node all flash VSAN: 3x Dell R630 2x Xeon E5 2650 v4 10 core 384gb ddr4 (16gb X 24) 1x 960gb intel DC nvme ssd 5x Samsung 2.5” SATA 1.92tb enterprise SSD

I just got two 2u supermicro x11 based systems with 12x 3.5” bays each that I’m planning to migrate all of my drives into from the VSAN and add a couple more. Each 2u contains 2x Xeon gold 5120 14 core, 384gb ddr4 (16gb x24)

Since I’m planning on using using strictly these 2 nodes to be my 24/7 cluster, I’ll need some shared storage. Some options may be: 2 node all flash VSAN (hosting the witness on one node, I know it’s not supported but it works) I do have a license for this Starwind VSAN (though I think I pass the community edition maximums) Host truenas scale on each with the raid controller passed through and replicate and host a shared ISCSI / nfs share (havnt done this yet and leaning towards it, anyone tried this yet?) Similar setup to scale, but windows storage spaces direct all flash Nutanix 2 node robo (might not have a license for it)

Anything else anyone can think of that might work well? Esxi is a hard requirement for the hypervisor.

Alternatively I do have an r730 with 24 2.5” bays, a single 12 core e5 2660 v4 12 core and 192gb ram that I could stick all the SSDs into and make a large dedicated truenas bare metal box, but I’d like to only power 2 servers 24/7 if possible as 768gb ram will do for my daily operations, I’ve got other clusters for spinning up and down depending on what I’m doing.

I’ve only got 10g Nic’s but I do have some space 40g ports on my switch, so 10g is the speed requirement, shouldn’t be hard at all, and even if I upgraded to 40g that should be a piece of cake as well.

TLDR best 2 node solution with shared storage running on ESXi? VSAN? Truenas on each ESXi host? S2D?
