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

• +$460: 2.20GHz
• +$1,628: 2.40GHz

16 total cores => 24 total cores

• +$1,200: 2.10GHz
• +$1,960: 2.30GHz*
• +$3,060: 2.60GH*
• +16,060; 3.00GHz*

*Availability delay, as of 12/22/17.

More details: 20MB Cache (85W)

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:

• See chart below for options with more cores and faster speeds.
• See write-up below chart for why we are pricing two-processor server options instead of  single- or four-processor servers.

Storage

All 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:

• 512GB, at $399.
• 1.0TB, at $749.

If more space is needed, more complicated and slower, but of course doable. Please ask.

Large amounts of data not needed to be stored on server, nor moved from server. Instead, simply deleted from server after processing.

64GB

(128GB is $880.55 more)

3 year, NBD

Dell on-campus "parts locker"

3 year, Advanced Parts Replacement Warranty

• +$150: 3 => 4 years

• +$375: 3 => 5 years

Option: Redundant power supply unit (+$224).

~$1,000 each

(*4 => $4,000)

~$5,500 for just the server

~$3,700. Compared to minimum recommendation:

• Older, cheaper processors
• Much less RAM
• Much smaller storage
• Warranty is 2 year longer and on-site
• Dual power supplies
• Better network card
