Cores, hyper-threading (HT) | 4 cores (one processor) i5-6500, 3.20 GHz (Not HT capable) | Total 16 cores (Two, 8-cores each) Each: Xeon Silver 4110, 2.10GHz 11MB Cache (85W) HT-capable | 16 total cores => 20 total cores
16 total cores => 24 total cores
*Availability delay, as of 12/22/17. | 16 cores (Two, 8 cores each) HT-capable Each: The now-older processor, Dual Intel Xeon E5-2620 v4 2620v4 2.1ghz processors with 8 real cores / 16 virtual cores per processorMore details: 10GHz 20MB Cache (85W) | Dual Intel Xeon Silver 4110 2.1ghz processors with 8 real cores / 16 virtual cores per processor | Hyper-threading (HT) is useful to the group. Group tested performance between HT being turned on and off on "CHEN-21". With HT, test system showed 32 cores. 25 of these could be used without saturation, and thus without delaying processing time. Without HT, only 16 cores available so maximum much less than 25 effectively used under HT. Notes:

Storage All SSD. | 500 GB SSD | 2TB is 4 times the space: 2.0TB Samsung 960 PRO M.2 PCIe 3.0 x4 NVMe Solid State Drive (cost is $1,499) Above configuration is the fastest option since combines OS and data on fast bus.
| If need less space, easy. Save about $375 per 500GB. Replace 2.0TB at left with:
If more space is needed, more complicated and slower, but of course doable. Please ask. | 400 GB SSD (380GB usable) | RAID-0 (striped) dual 240GB SSD drives acting as a single 480GB SSD for performance | Large amounts of data not needed to be stored on server, nor moved from server. Instead, simply deleted from server after processing. |

Core prices snap-shot
- Prices taken 12/22/2017
- Prices go up dramatically with both core-count and processor speeds.
- Cache sizes and power consumption also increase with capabilities.
- This chart of estimated marginal costs is a sub-set of options pulled from <https://www.thinkmate.com/system/rax-xs4-21s1-sh> and <https://www.thinkmate.com/system/rax-xs4-21s1-10g>, focusing on SLOWEST procs to reduce costs. Other, more expensive-per-proc (faster) options available.
