I thought that I would like to replace my server at home, I made various selections and summarize it. The current environment is as follows.
- DELL PowerEdge SC 440
Besides I have a network equipment of Cisco, Juniper and constitute my home lab.
The missing part at present is the correspondence of nested virtualization and the memory capacity. In addition, since it is used at home and individual, I basically want used Server.
- The premise is virtualization environment
- Server Usage
- Server Selection
- Selection of CPU
- Selection of memory
- DISK Selection
- rough estimate
- Find second-hand server
The premise is virtualization environment
As an assumption, do not install OS directly, virtualize with VMware ESXi. In selecting, I would like to be able to use nested virtualization. The background is as described in this article.
The main application is verification of network technology. I would like to verify the technology of IaaS, PaaS such as virtual appliances such as Cisco, F5, management system on Linux, VMware, Open Stack, Docker, Cloud Foundry etc. It is extension of home lab.
The server requirements I want are as follows. Select the case and customize the parts.
- CPU: Core i series or Xeon series
- Memory: 8 GB or more (preferably 16 GB)
- DISK: 1 TB (SSD unnecessary)
I do not think about making my own server, and make it an existing product. Although my own making may be more free, considering the troubleshooting at the moment, I believe that the ready-made products used by many people are better.
Since it is a home server, it is not a rack mount but a tower type. Selection candidate series are as follows
Both are wonderful products, but this time DELL PowerEdge is chosen.
I am using PowerEdge now, so I have some attachment. In addition, other manufacturers are putting emphasis on SI business, but DELL is good impression of product main. (DELL is not without SI though ...)
PowerEdge model number
I want to hold down the price inexpensively, so think with a missing shape rather than the latest model. However, I want performance, so choose from T series rather than SC series.
Specification comparison (maximum)
|CPU||X, C2||AMD||X, Ci||X, Ci||X, Ci||X, Ci||X, Ci||X dual|
Detailed specification comparison here
Since the CPU assumes it as a premise to replace, the type of the socket becomes important. Since it is necessary to match with the socket type of the installed CPU, carefully select it. The socket type is gathered neatly here.
Considering the second hand market as of 2016/12, T110 II is considered to be the optimal choice.
Selection of CPU
Since we decided to adopt T110 II, we need to consider the CPU of socket type LGA 1155.
The index of CPU performance was interesting and easy to understand this article. (Sorry in Japanese. Previous Page is easy to check in English)
I want a battle power of 5500, preferably 8000 if possible. Because I want to keep price cheap, because it's second hand, I will search within 10,000 yen. Since it is quite difficult to find the desired setup item, it is assumed to be replaced. (US $1.00 = about 100 yen)
Because it is a server, Xeon is the best CPU, but concern is that Xeon is basically expensive. I will consider it carefully in the Core i series. For generations of Core i3, i5, i7 this article was easy to understand.
Xeon E3-1220 4Core 4Thread 3.1GHz (Maximum: 3.4GHz) Combat Strength (Tentative): 6088 Used Market: 5,000 - 7,000 yen
Xeon E3-1220v2 4Core 4Thread 3.1GHz (Maximum: 3.5 GHz) Combat Strength (Tentative): 6532 Used Market: 8,000 yen
Xeon E3-1270 4Core 8thread 3.4 GHz (Maximum: 3.8 GHz) Combat Strength (Tentative): 8408 Used Market: 12,000 - 15,000 yen
Selection of memory
To be honest, memory is not particularly sticking, as long as it has molds and works.
At a cheaper place with a brand new;
4GB: 2,500 yen
8GB: 5,000 yen
Even though DISK is not particularly committed, it has confidence in Western Digital. Roughly Seagate has heard that the failure rate is high and was hateful. However, in the survey of 2016 it seems that Western Digital has a higher failure rate than Seagate. Toshiba has little market share, HGST is too expensive to exclude from consideration.
It seems that the failure rate is getting higher in WD, so I think Seagate is dominant now.
Approximate estimates of CPU, Memory, and DISK are as follows. Within 30,000 yen.
|XeonE3-1220||7,000 yen||E3-1270 + 8,000 yen|
|Memory (16GB)||8,000 yen||Used 4GB*4|
|HDD (1TB*2)||16,000 yen||Seagate brand new RAID|
Find second-hand server
Unexpectedly, some items of used goods that satisfy the requirements are listed.
There is nothing that perfectly meets your wishes, so it is good to consider which parts are to be compromised and replaced, consider purchasing.
(Sorry!! There are Japanese Services)
Speaking of cheap second hand Yahoo auction. However, it becomes short as it becomes a server.
Used server DELL PowerEdge T110 (4 Core)
35,000 yen (37,800 yen including tax)

There is a certain degree of exhibition and you can choose.
Surprisingly Rakuten's exhibition is cheap, it is considered to be the most promising among the candidates.
When using it as a home server (home server), DELL PowerEdge T110 Ⅱ is considered reasonable. The processor uses Xeon E3-1200 series to ensure performance. It is second-hand server specialty store, although it is not cheap, it can purchase and customize it from 30,000 yen to 50,000 yen. With this you can live comfortable home lab life.
