Greetings,
 
I'm setting up a small pool for about 40 small VMs to run on a set of 3 Dell servers.  These are pretty lightweight VMs for web servers and they're not mission critical.  We already have some Qnap storage servers that we'll be splitting the storage loads onto.  I was hoping to get some tips.  The layout is pretty basic I think, just three R230 Servers with 4 NICs bonded going into a Dell switch and then into the 2 QNAP servers.  I'm thinking of using NFS for the storage network.
 
3 x Dell 230 PowerEdge Servers
Intel® Xeon® E3-1220 v5
64GB RAM
2 on board GBe NIC
4 additional GBe NIC (Intel 350)
1 TB HDD (For OS - cheapest option)
4 x GBe NICs Bonded for storage network
1 GBe NIC dedicated to management network
1 GBe NIC dedicated to public Internet
 
Dell X1052 Switch
 
NAS 1
Qnap TS-1635
12 x 1TB WD HDD
4 x SSD 850 EVO
2 Port 1GBe Network Card add-on (4 total)
4 x GBe NICs Bonded for storage network
 
NAS 2
Qnap TS-453A
4x2TB WD2005FBYZ
4 x GBe NICs Bonded for storage network

Keeping with NFS is what I would do, no reason to overly complicate with iSCSI, especially with a single switch. For your nics I would do bonding two nics for storage/management/public internet (I assume this is what we typically call VM traffic).

Hello Alan,

For bonding do you mean each usage is bonded separately like:
2 Bonded for Management

2 Bonded for Public
2 Bonded for Storage

Or do you mean use one bonded pair for all of the above combined?

I care more about the storage performance than either management or public.  I'm hoping to 100MB/s out of the storage.  The overall disk usage is not a lot but I'd like it to be reasonably fast.

Currently I only dedicated one NIC to management and one to Public and it's been quite reliable and the performance is great so I'm happy to continue that.  Hopefully that makes sense!

 

Thanks for the confirmation on NFS.

Separate bonds for each of the three, if you have 6 NICs. The goal is to isolate the network traffic as much as possible into each one of these distinct areas.

Yes, 3 separate bonds, sorry I lacked clarity on that. The bonds for storage and management are more for availability than for throughput. A second switch for switch redundancy would also be desirable.

Great, thanks for the clarity.  I think I'll use a separate switch for storage. I'm feeling confident about this configuration.  Hopefully the performance of the equipment will be reasonable.

Qnap and Synology make pretty nice drive configurations, especially the smaller ones that are often more than enough and way less costly than something with 8 or 12 or more drive bays.

That's great to hear.  I've had good luck with most Qnap devices over the years mostly as backup/repositories.  
I spoke to Dell today and apparently I can have as many as 18 network ports in an R230.  I've added another pair to each machine so I can pair up all of the adapters as suggested and still have 4 for storage.

2 Bonded for Management

2 Bonded for Public
4 Bonded for Storage

Mike,

That sounds like a reasonable network configuration!
