Abstract

The utility model relates to a server device. The technical result is the ability to visually review the light indicators of the operating status of the air cooling fans of the server for quick individual replacement of failed fans without disconnecting and dismantling the server. The device comprises a chassis, inside which computing modules are placed, and shelves are installed on its rear panel for installing air cooling fans outside the chassis. Each shelf is intended for installing only one fan, and there is a distance between adjacent shelves. The technical result is increased ease of maintenance. 2 cl., 5 fig.

Description

The field of technology to which the utility model relates

The utility model relates to the design of rack-mounted solutions for server devices intended, in particular, for installation in universal chassis racks, for example, in data processing centers.

State of the art

From the prior art, a known server device with a chassis, inside which computing modules are placed, while the chassis on the rear panel contains group modules of air cooling fans (RU 178957, published 04/24/2018). The disadvantage of this known device is the limited visual overview of the light indicators informing about the status of the fans.

The essence of the utility model

The utility model solves the problem of increasing the ease of equipment maintenance.

The technical result achieved: the ability to visually view the light indicators of the operating status of the server air cooling fans for quick individual replacement of failed fans without shutting down and dismantling the server.

The specified technical result is achieved in that the server device contains a chassis designed with the possibility of placing computing modules inside it, the said chassis on the rear panel contains shelves for installing air cooling fans, wherein each said shelf is intended for installing only one fan, and there is a distance between adjacent shelves.

The shelves contain a means of securing the fan.

The shelves can be made removable.

Implementation of a utility model

A server device is computer equipment designed to perform a particular service task in interaction with other elements of computer systems. Server devices can be implemented as software and hardware complexes or workstations and usually include several computing modules.

A widespread approach is to create server devices in the form of chassis racks or server racks, in the cells of which the required number of computing module carriers (the so-called "chassis") are installed. Several computing modules can be placed in the chassis. According to this principle, server devices are created within the framework of the OCP (Open Compute Project) standard.

A typical rack chassis 9 is shown in Fig. 5. On the rear side of the rack chassis 1 are located air cooling fans 3, equipped with indicator lights 7, indicating the serviceability of each fan. By the color of the indicator light 7, the operator can visually determine which fan 3 has failed and replace it by visually viewing the rear side of the rack chassis 9. Existing chassis designs allow the operator to view the indicators 7 only in a certain area 8, since multi-seat shelves or single-seat shelves installed without a lateral interval block the indicator lights 7 located outside the area 8. In order to see all the indicator lights 7, the operator must change his body position, bend over, move, etc., which leads to a loss of time for establishing the operability of the fans 3 and causes inconvenience.

According to the utility model, the server device contains at least one chassis 1, inside which computing modules 2 are placed, and on its rear panel shelves 4 are installed for installing air cooling fans 3 outside the chassis. Each shelf 4 is intended for installing only one fan 3, and between adjacent shelves 4 there is a distance, as shown in Fig. 2. The number of computing modules 2 placed inside the chassis 1 can be from two to six.

The arrangement of the fans inside the chassis excludes access to them from outside the rack, which leads to the need to disconnect and dismantle the server from the rack if necessary to notice the fans. In this utility model, the fans 3 are located outside the chassis for quick individual replacement of failed fans without disconnecting the server dismantling.

Each shelf 4 of the fan is made to accommodate one fan 3. This makes it possible to install shelves 4 with a lateral interval, i.e. with a distance, and thereby improve the visual view of the light indicators 7.

Shelves 4 can be made removable. This will further increase the ease of maintenance, since unused shelves can be quickly removed, thereby expanding the view of the indicator lights 7.

Each shelf 4 may be provided with means for fixing the fan 3. Such means may be made, for example, in the form of a shaped groove 6 and a screw 5.

The utility model works as follows.

The required number of chassis 1 with computing units 2 installed inside is installed in the rack chassis 9. Air cooling fans 3 are installed on individual shelves 4 on the rear side of the chassis 1. The power is connected and the device is started.

In accordance with the maintenance regulations, the operator periodically inspects the rear side of the chassis rack 9, and by the color of the light indicators 7 determines which of the fans 3 has failed. Due to the presence of lateral intervals between the shelves 4, the operator, without changing his position, can see almost all the light indicators 7 and, if necessary, quickly replace the failed fans without turning off and dismantling the server.

If necessary, the operator quickly disconnects and replaces fan 3 without disconnecting and dismantling the entire server.
