New server recommendations?

[Norman Uittenbogaart]

I want to build a new server.
I was thinking a i7 7820x with 128GB RAM

Now the question is how to arrange the harddrives.
I have 9x 1TB HDD's which I would like to keep using.
How can I optimize speed with ZFS?

Should I buy a NVMe for L2ARC & ZIL ?

i7 looks more like a desktop system, not a server.

If you go for ZFS, use only server components and high quality ECC ram. And yes, NVMe can speed up your ZFS.

Ok what would be the ideal server setup, keeping the disks in mind

 

[alexskysilk]

you're asking the questions backwards.

What are you trying to accomplish? is this a production system? if so, what workloads are going to be running on it? figure that part out first; then decide what is the base performance you require and your fault tolerance. then decide how much you want to invest in initial purchase and how much to spend in operating costs (eg, electricity, cooling, network, etc.) THEN you can start putting solutions together

It will be a production system, running 1x windows server with MSSQL, 1x ORACLE db, a mail server, a webserver and a samba server.
All reasonably lightweight, 15 users will be working on these servers.

What it really matters is you need SSD drives.

i7 will work fine if you have SSD drives.

 

[Vasu Sreekumar]

Use RAID1 with 2x1TB for Proxmox (local) and RAID5 with SSD drives for VM storage.

Only problem with that is, I need allot of storage ....

 

[Vasu Sreekumar]

Space VS speed, that is your decision.

 

[Norman Uittenbogaart]

What I'm trying to find out is what the speed impact would be running ZFS with a ZIL / SLOG on a good SSD (which has power out protection).
And having the "slower" hdd's behind that.

But haven't found directly the speed impact

RAID1 with 2x1TB for Proxmox (local) and RAID1 with 1TB SSD drives for VM storage.

This is what I use and i can run upto 6 or 7 KVM or 15 LXC.

And it is reasonably fast.

a slog helps writes quite a bit, and makes the whole filesystem feel snappier. a little bit goes a long way- it doesnt have to be large.

So would you normally set a SLOG & L2ARC?

 

[alexskysilk]

slog, yes. l2arc- no. check the forums, there is exhaustive discussion on the subject.

It's what I thought, but in the movie he only uses it as l2arc.
