I decided to use my old server (Lenovo TS140) to replace my present one (Dell R730XD), There were two factors in my decision (1) it was more stable (2) it consumed less power at ~50W vs ~99W. However, before I could do that I wanted to make two key upgrades: (1) more than 4 cores/4 threads and (2) faster than gigabit networking.
Hardware Options
Processor:
- E3-1225 v3 (Current Processor)
- Links: Intel / Tech Power Up
- 4 core 4 thread
- Base: 3.2 GHz
- Max Turbo: 3.6 GHz
- IGP: Intel HD P4600
- TDP: 84W
- Single/Multi: 2014/5322
- E3-1245 v3
- Links: Intel / Tech Power Up
- 4 core 8 thread
- Base: 3.4 GHz
- Mz Turbo: 3.8 GHz
- IGP: Intel HD P4600
- TDP: 84W
- Single/Multi: 2150/7044
- E3-1275 v3
- Links: Intel / Tech Power Up
- 4 core 8 thread
- Base: 3.5 GHz
- Max Turbo: 3.9 GHz
- IGP: Intel HD P4600
- TDP: 84W (listed as 95W at places)
- Single/Multi: 2198/7203
NIC:
- Used Intel X710-DA2
- roughly $30 from eBay
- 10 Gbps SFP+
- Requires a PCIe x8 slot
- Realtek RTL8125B NIC
- roughly $17-20 from Amazon
- 2.5 Gbps
- Requires a PCIe x1 slot (PCIe 2.0 x1 provides up to 5 Gbps of bandwidth)
Decision
I went with the E3-1275 v3 as it was roughly the same price as the E3-1245 v3 and was slightly faster.
I chose the Realtek RTL8125B from GiGaPlus as it would keep the x16 slot free in my TS140 for future expandability. I also only had a single free SFP+ port on my switch,
