Abstract

A server chassis, consisting of a chassis that contains vertical rails for fourteen server blades in the front part and one more compartment on the side for a control module in the format of a server blade, and built-in switches are installed in the chassis rack in the back of the chassis, which switch all network interfaces from 14 server blades, and a management module for 4 × 10 Gb / s SFP + slots.

Description

The utility model relates to computer technology, in particular to an improved server chassis that can be used in various types of devices, such as servers. Switches integrated in the server chassis rack save space

Many various such electronic products are known in the art.

The closest of them is the chassis of the blade server, known from US 2008266813. Moreover, to expand the capabilities of the computer system in a relatively small physical space, several server blades can be installed in the chassis of the blade server.

The blade server includes an access panel that is attached to the vertical side of the blade server. The access panel provides personnel access to the blade server components for maintenance. These components include processors, memory, storage, network interface modules, and other components installed on a blade server. Access for service personnel to the components of the blade server is through the access panel of the blade server, moves the blade server without accessing the chassis of the blade server. Moreover, the maintenance of the blade server can be carried out with the components extracted from it.

Serving the blade server outside the blade server chassis provides blade server maintenance personnel with convenient access to the blade server for routine maintenance, such as replacing the computer processor of the blade server, installing more machine memory on the blade, replacing the blade server in server blade chassis to a new server blade, and so on.

An advantage of a blade server chassis over all known devices of this type is that it is relatively easy to maintain and requires no additional workplace for maintenance due to its use.

A support caliper is also installed to support the blade server installed in the chassis of the blade server. The support caliper connects to the blade server chassis and the blade server and is required to maintain the blade server when serviced outside the blade server chassis. Using a support caliper allows maintenance of the blade server outside the chassis of the blade server.

The difference between the claimed utility model and the well-known close analogue is that the server chassis contains two built-in switches that save work space. In one chassis, you can install two different modifications of server blades at the same time.

The technical task was aimed at obtaining an improved server chassis having optimal operational characteristics, such as saving space.

The technical result is the saving of occupied space, which is achieved due to two built-in switches installed in the chassis rack in the rear of the case.

The use of built-in switches reduces the number of network cables used, which leads to space savings in the chassis rack (saving space), two built-in switches are installed. The LE301 switch switches all network interfaces from 14 server blades and a management module to a 4 × 10 Gb / s SFP + connector.

Each of the LE301's built-in switches has a wide range of functionalities available to Layer 3 switches.

The server chassis is illustrated with an illustration of the location in the chassis rack at the rear of the chassis of the two built-in switches, shown in Figure 1, which describes the front of the server chassis, with an illustration of the location of the server blades in the chassis rack.

The server chassis consists of a housing (4), containing in the front part vertical guides for fourteen server blades and another compartment on the side for the control module. In the middle part of the case, a connection board (7) and a fan unit (8) are integrated.

In the front of the case there is a module containing server blades in an amount of up to fourteen pieces (6), which are installed through vertical rails and connected to the connection board through connectors, and a control module (5), made in the format of a server blade and located in front of the chassis in the compartment on the side. Server blades are connected to the control module via the connection board using I2C and COM interfaces, while the control module through the I2C and COM interfaces monitors and controls the blades. Built-in switches (2) are installed in the chassis rack at the rear of the chassis. For ease of maintenance of the connection board and the fan unit, the cover (1) is located on the top of the connection board and the fan unit by the power supply unit to the chassis rack in the rear of the case.

The connection board (7) and the fan assembly (8) are integrated in the chassis in the middle part. In the middle part of the case, on the side of the connection board and the fan unit, a power supply unit (3) is built into the case. In front of the housing is a control module (5). Built-in switches (2) are installed in the chassis rack at the rear of the chassis. A cover (1) is located above the connection board and the fan unit by the power supply unit to the chassis rack in the rear of the case.

The claimed server chassis (EcoServer R314) consists of a case containing vertical guides for fourteen server blades in front and one more compartment on the side for the control module, backplane (connecting plate), top cover of the fan unit, power supply unit with hot-swap 1 + 1 hot -swap (1200W), 3U chassis, under 19 ″ rack, and includes up to 14 modules of computing (server) blades in two versions EcoBlade LR301 with one processor and EcoBlade LR302 with two ARM processors - Marvel1 Armada ХР, as well as a control module (MUiM).

Up to 14 LR301 and LR302 blades can be installed in the Rikor EcoServer R314 chassis; in a particular case, up to 14 blades can be installed. They are mounted in the chassis in vertical rails and connected to the backplane via PCIe slots.

The server blades LR301 and LR302 are independent of each other, which allows them to be installed and replaced without having to turn off the power of the entire chassis and stop the rest of the servers. Using LAN interfaces, they are connected to the built-in switches. To increase reliability, each blade is connected to both switches. Using I2C and COM interfaces, the blades are connected to the MUi M control module, which through these interfaces controls and controls the blades. The USB interface is used to connect external storage media.
