Server room or cabinet with active noise cancellation
Hello. This is my first post, so please do not judge strictly.
I am the owner of a small company, in combination I set up all my servers myself. I have a fairly simple network architecture with four 19 "physical servers, which recently lost their kolokshen to the server landlord. The
question arose of allocating a server room from the total area of the server room with compacting the team or installing a silent cabinet, the principle of which has already been described in Habré.
Then I will try to determine for myself: build the simplest server room or install a silent cabinet.
From the calculations, I will throw out the same work for both cases, such as: power supply, switching, and other identical work.
Calculation of the cost of ownership of the server
Input data for the calculation will be:
- the minimum server area according to the ANSI / TIA / EIA-569-B standard should be at least 14 sq.m., but foreign standards for us are not a decree. We took as a basis 8 sq. M. m., so that the cabinet could be approached from either side;
- rental rate per sq.m. - 1000 rubles per month;
- minimal construction work on the construction of the server: plasterboard partitions, noise insulation, wide door, fire alarm, lighting, ceiling alteration;
- The simplest cooling system for household air conditioning without redundancy;
- sufficient budget server cabinet CMO 42U with ventilation modules ;
- tenure - 3 years, since in our country any leader from the field of small and medium-sized businesses does not look beyond 3 years.
Calculation:
- the cost of owning an area for 3 years is 1000 rub. / Sq. M. * 8 sq. M. * 36 months. = 288 000 rubles.
- the cost of building a server - 50 000 rubles.
- the cost of installation of air conditioning - 60 000 rubles.
- the cost of the cabinet with ventilation ventilation - 66,500 rubles.
TOTAL for 3 years: 464,500 rubles.
Calculating the cost of owning a silent cabinet
The input data for calculating the cost of ownership of an active noise-canceling technology Silentium's cabinet:
- the area occupied by the cabinet is 1 sq. M .;
- rental rate per sq.m. - 1000 rubles per month;
- air conditioning in the office is already installed;
- tenure - 3 years.
Calculation:
- the cost of owning an area for 3 years is 1000 rub. / Sq.m. months * 1 sq.m. * 36 months = 36 000 rub.
- the cost of a typical silent cabinet VIST AcoustiRACK - 420 000 rubles.
TOTAL for 3 years: 456,000 rubles.
SUMMARY
We will summarize unscientific - without weight coefficients, trite by the number of pluses.
| Server room | Silent cabinet | ||
|---|---|---|---|
| cost of ownership for 3 years: 464,500 rubles. | cost of ownership for 3 years: 456,000 rubles. | ||
| most of the investment "spread" for 3 years | most of the investment must be allocated immediately | ||
| when renting additional space for the server room, there may not be small areas in the business center or there may be no free spaces at all | You can always allocate 1 sq. m. from the already rented area without serious sealing of employees | ||
| allocation of space for the server in an already operating office is associated with the compaction of employees | You can always select from the available office space 1 sq. m. without staff seals | ||
| not every landlord will allow office redevelopment | in accordance with the landlord is not necessary | ||
| the need for construction and electrical work | electrical work only | ||
| when moving the server will have to build again | mobility - transported wherever it wanted | ||

Честно говоря, при всей своей очевидности, решение я еще не принял.
