2 questions: Starwind + Hyper-V core possible? Starwind vSAN 1 NIC + 1 onboard?

hubtechagain

as for nics, i'm not sure if it's required, but i think you need 2-3 per host.

Thanks all for the replies.

Also, the video creator mentioned that the live migration is not actual real time as the VM needs to spin up and may takes from seconds to minutes. Is it true?

Yes, there is a hiccup as the workload is brought back online on the second machine.

Thanks SAM. I'll take minutes over hours any day.

Generally not minutes, spin ups are extremely fast. Often just a couple seconds so generally people don't even notice.

Do you recommend getting SSD for OS partition? I'm thinking xByte Edge 240GB in RAID1. I am also submitting proposal to increase HDD to 6 to reduce bottleneck. .

No, the opposite. Every penny invested in the "OS" storage is wasted. You don't care about capacity or speed there. Best practice is to install to SD card or USB stick when possible (Hyper-V only installs) or to the main array itself, never split off.

If you were to split it off, which you never would, it would go on the cheapest, smallest, slowest SATA drives that you can get (WD Red SATA.)

The server came equiped dual 8GB SD Card. Is it enough for both vSan and Hyper-V core?

LAH3385

If I have 4TB of storage capacity using all available HDD slots.. is there a way to increase the capacity down the road?

I think so but I am not sure of the exact size needed.

If you have filled the box, no there isn't a super easy way to make it bigger. You can always add capacity through bigger drives, external arrays, bigger server - in what way are you thinking?

That is not big enough for Hyper-V, I believe that they wanted 32 for the SD/USB. I would have to look again.

Right now we are about 1.5TB in. So in 5 years we may hit the 4TB mark. Just want to make sure that I have a good understanding on this.

You can always do a one time "grow" by taking a backup and moving to bigger drives. Even today you can hit 8TB with a single drive pair. So you have tons of head room.

And a few years from now you would likely replace the server, not increase storage. Growing storage always sounds better than the reality is when the time comes.

LAH3385

@scottalanmiller Good point.

Is there any gain or loss if I install Hyper-V server on the main array?
SD Card is not an option for us since it only has 8GB. So we will be getting low profile USB instead.

Nothing wrong with that.

scottalanmiller

Or, you know, put in the right sized SD cards. That it came with 8GB isn't a factor.
