The younger brother of 90 terabyte gravitsapu.

Writes basanovich:

... Or how to store data in a locker +) Yes, yes. Inquiring minds do not stop. I wrote Alexander, inspired by the sensational in runet 90 terabyte gravitsapu and decided to assemble his small, but highly amusing. Design feature is that it is very good scaled to virtually unlimited size, while there will be where to put tables ask skeptics and critics consider this design on in terms of features the construction of nuclear reactors, as well as the fun home crafts.
A short story from the author:
Actually the process of creating sprawling somewhere in the month. It is based on plain old battered chipboard cabinet, on the sidelines of any public office dime a dozen.

Black things that catch your eye - a deflector 3 by 2104. Through them out all the air. Conventional rail on wheels were replaced with full extension ball. Because of the mounting rails to gorizintalnoy shelf - you can open the drawer, or both at the same time or just the bottom.

The top drawer is only motherboard stuck in her controllers vidyuhi and a second network card.

While involved in all 6 hard drives, but as you can see, the potential of the tables have

Corpus tables pasted anti-vibration material to reduce noise. The buffer zone is generally made for the same. In principle the partition wall can be removed. The meaning of this will not change. The fan blows air into the lower chamber of the UPS and the air through a single slit near the hard drives will come out of this camera, but ... when the air falls within the scope of which has a narrow exit - creates a resonance frequency is proportional to the size of the chamber where the air circulates. In this, for this circulation it has been allocated just 6cm instead of the entire volume of the lower chamber. So low bubnilovo been replaced by high urchalovo :-)))

Total:

1) The design was very heavy and very quiet.

2) It is worth it all in the kitchen. As the volume is equal to the refrigerator Liebherr :-)

3) the centrifugal fan from the stove some budgetary foreign cars. The drum fan is larger than that gazelevskoy stove. Sam the engine is connected to 5V, but an internal resistor voltage is reduced to 3V. (the regulator can be seen on one of the gallery if you look closely). Regulator can be 1.7V, 3V or 5V. Conventional rotary switch from 2108.

4) Total System 4 Fan: centrifugal, zalmana7000 2 processors (they are controlled by motherboard. Turnover of 50% or more on heating) and 1 small fan 5c connected to 3.3V. It also can not be heard. The temperature of the working system can also be found in the pictures. Hard disk can not be heard, because they are completely isolated damped front wall.

5) Materinka Tyan Thunder K8W (S2885), 2 strips of 1GB of memory with ECC. Controller SATA LSI 8x. 320 SCSI controller LSI. On the mother has 4 sata. 2 AMD Opteron processor 285 (2.6GHz 2yadra each)

6) The system Ubuntu 10.04 server. Apache, ssh, samba, mail, mysql, ftp, transmission. Net + gives a second computer in another room. In addition to the server my site is still spinning 12 others.



7) For those who understood and will repeat: the design is very easy to scale both in width and in height. Ie You can take a wide bedside table and put on a shelf 2 mother with the same layout nodes. You can rack with hard drives to make deeper or higher. Disks put in 2 rows in height or depth. Even in my gravitsapu there is room for another PSU ... If for example 12 hdd one will be enough.

8) The circuit cooling comes up with a very long and hard. The challenge was not simply to do something where the air blowing and blowing somewhere, and all deliberately blow the heating part, do not lose the flow and does not create it where it is not needed.

9) This implementation should be seen as a working model Well structured body, which (if you have time and desire) will be implemented in a different material.

10) The idea of ​​a single, centrifugal fans but how it came unexpectedly brilliant. He sat in the car and thought why car heater gives a great air flow and so still work? Yes, and with a filter at the entrance ...
