Synology DS1817+ or DS1517+ virtualization eo ...


I have a Synology DS414 now (home use only) but would like to run
virtual machine manager, cloud drive (family use), web station (my public site), audio station (share with family) & other packages on it.

I have 3 questions:

*I think the DS1817+ would be a good choice to runvirtual machine manager, right (maybe somewhat overkill -4 ethernet ports whereas I only have 1 network-)?
*I' hope to run a:
-W2K16 domain controller
-sccm server with sql and
-windows 10
-virtual synology to host a website

Therefore 32 GB would be needed, that is supported? I did found a place to buy the ram for it

*I have 4 disks (Seagate Green 2 TB) in my current setup, the  DS1817+ has 8 so I could add 4 more ssd's to put my
vm's on (raid 0 for speed, then backup my machines via ?).

*Which config (I  know there is some caching possibilites)/SSD's would recomend?

The idea is to have my main storage on my 4 disks, then run an ssd cache on extra disk, then other 3 SSD's in raid 0 for vm's.

Any other input welcome.

we would opt for the larger capacity DS1817+ unit, Synology bottlenecks are often

1. disk slots
2.  NAS memory
3. NAS cpu

Purchase slow SATA disks, and then use SSD Read and Write cache to enhance performance on the volumes.

Ok, thanks for your input. Then I could also go for ds1515+. Do not need the 8 slots, only wanted it to run vms. So I could then add ssd for cache to my 4 disks (slower ones), will that be better then having (on ds1817+) 4 ssd in raid 0 to run vm s?
Depends on your VM workload

you are going to use internal VM manager, not VMware or Hyper-V

4 SSD in RAID 0, no raid >?
Review of ssd cache is good but it is expensive. 200 Euro for card without ssd. For 400 Euro (or less) I could buy 4 ssd to add in the 4 bays of Dr 1817+ ....
Want to stick to somewhere around 1200 Euro. Note that mostly I will only 1 vm (Synology vm) for running a personal site and I have only 1 UTP cable for nas in home network. Don t want to overdo it, mostly my current nas isn't doing really much. New one would be a lab environment and sharing Synology apps between some friends (Drive, Music, Office etc).
Does this device not use standard SSDs for read and write cache our Synology units do!
Don t know. Ok, so you have Synology too...
So what is the difference with this card and dad in the slots then?
This card must be something new....NVMe plug in flash card.

Or you could build yourself a XPEnology using a HPE Gen8 ProLiant Microserver for little money!!! - Hint Google!
Thanks! I had a Microserver with 6 ssd bay and ESXI running on it. Even a seperate Microserver with 'superfast' storage (forgot the technology).
Still have the LSI raid controller .... Bottomline: don't have time left to configure it ... and it will always ask lots of configuration and maintenance.
Then  also things break, like I had 16 GB in it but it wasn't recognized at every boot.
When I would build the thing again (for which I do not have the time), then it still would cost be quite some money.

Made the calculation: for a DS 1817+ plus 2 SSD's of 250 GB (what makes a RAID0 of 500 GB, plenty enough) I'd pay a 1000 Euro.
Then I have a hassle free NAS which I can run a vm on, from time to time. If not needed, I power them off, if upgrading the nas/rebooting the nas they will come up with the nas, if no vm's used, the synology will use less power.

So 1000 Euro but only for 2GB, the Synology would support 16 GB, but found this 32 GB for 300 Euro 

=> Should/can I trust that?

(If yes, I will have a 32GB, quadcore 2,4 Ghz machine with 500 GB in RAID0 SSD, plenty enough for me :-)).

DS 1817+ has a PCIe bus slot, and also M.SATA connectors for SSD or PCIe Flash card, so you do not have to use standard SSDs in the disk slots, and use them up.
the cpu is an  Intel Atom C2538 so don't expect to run much in the way of a virtual machine
Thanks guys, but what are my options then?  XPEnology has only version till 5.2 ....
then also, would love to make a rock solid microserver with 32 GB ram but there are only 4 slots for my 4 sata disks  so it will be slow too.
