Workstation / server / PC build

[kno3]

Build for 2 VMs; 1) Database, data handling and data processing server (one ubuntu VM) and 2) VM for personal use (although also used for data processing). 

 

Appreciate any feedback.

 

CPU	Intel i7-5820K
PSU	Corsair RMi850 Modular
HDD	[x4] Seagate SSHD 7200 RPM 3.5" 2TB SATA 6GB/s 64MB Cache (RAID10) (for database storage)
SSD	[x2] Samsung 950 512 GB M.2 (one for each VM)
RAM	Corsair Vengeance LPX 32 GB (4x8 GB) 2400 mhz C14 XMP 2.0
Motherboard	Asus X99 Deluxe (or Asus X99-E Workstation (WS) X99)
Cooler	Corsair Hydro H105 240 mm
VGA	Evga/Asus Titan X 12GB 1000 Mhz (potentially 2x for each VM)

Don't get Titan x. A 1080 will outperform for cheaper.

Titan X is more useful to me due to the higher number of CUDA cores, since I'll be using CUDA.

I'm not sure the Samsung 950 Pro M.2 drives are worth the cost premium. More memory and/or (perhaps) a more powerful cpu would be a better place for the $. Good ssd like Samsung 850 EVO should do a very good job as system drives.

Good point. Although was planning on going for M.2 for the server to get the best speed possible, considering the server will be doing a lot of data transfer with database reads and writes. My idea was to have reasonably sized databases on the NVMe for fast queries and data retrieval and big(ger) databases on the raid 10 system. For redundancy of M.2 data I'm thinking maybe I'll raid 1 it to an SSD although not sure as that would lose the advantage of M.2 over an SSD I believe?

I would expect that mixed device speeds in a raid 1 array would result in the array running at the speed of the slowest device.  

 

What sort of i/o volumes are contemplated? If the ssd based databases support high transaction volumes, one should be looking at enterprise level hardware. Otherwise the drives may not last very long.
