Abstract

FIELD: information technology.

SUBSTANCE: blade server contains two motherboards that are installed in the lower tier of the blade server enclosure in one plane, the other two motherboards are installed in the upper tier and fixed side by side in the same plane, each with a 180 degree rotation around the longitudinal axis to the motherboards of the lower tier. The longitudinal axes of the four motherboards are parallel to each other. The motherboards are arranged in such a way that when one board is in a plane parallel to the plane of the other motherboard and rotated 180 degrees around the longitudinal axis to another board. A minimum distance between the planes of the data of the motherboards is reached. And the heat sink radiator of the CPU of each of the motherboards faces the memory modules of the opposite motherboard and has a relief recess for unimpeded passage of the memory modules without contacting the heat sink radiator.

EFFECT: increased computing density.

Description

The claimed invention relates to the field of computer technology and can be used in the design of blade servers for computing, in particular non-resource-intensive computing, encoding-decoding, processing Web-front-end requests, routing and access, content delivery and caching (CDN and streaming), non-resource-intensive hosting, processing in distributed data warehouses, as well as computer modeling.

A blade server is known from the prior art, comprising a chassis for installation in a 3U chassis, a motherboard, a base backplane for connecting the motherboard to the chassis, no more than two 2.5 or 3.5 inch hard drives, a PCI-Express 3.0 expansion card LP, while the motherboard contains one central processor (Central Processor Unit - CPU), a 64 GB RAM module, a system chipset containing the following user-accessible interfaces, such as 2 × SATA3, VGA, Gigabit Ethernet BMC (GBE BMC) , PCI Express 3.0 LP, PCI Express 3.0 Micro-LP, 2 × USB 2.0, USB 3.0 (http://www.supermicro.nl/product s / system / 3U / 5039 / SYS-5039MS-H8TRF.cfm).

The disadvantage of a blade server is the inability to install more than one motherboard and / or one PCI Express 3.0 LP expansion card, which significantly limits the ability to increase the computational density, the number of additional ports and hard drives installed.

At the current time, there is a need to increase the performance of blade servers, which imposes a requirement to increase the density of the computing device. Many of the existing resources necessary for the operation of computer systems and data centers can be used to support additional capacities provided that additional computing devices are added to existing chassis and racks in data centers. While most of the efforts are aimed at changing individual components of the server, a positive effect can be obtained from modernizing systems by making more efficient use of the internal space.

Currently, blade servers are widely recognized and actively used, the tendency to increase the density of computing has led to the development of a double density blade server. The idea of a dual-density blade server is to place two servers in a chassis that has the same form factor as an existing blade server. Thus, the installed base of the chassis of the blade servers without any hardware changes can be used to support the operation of the double density blade server.

According to the results of the analysis of the prior art, the closest analogue to the claimed invention is a blade server comprising two motherboards. Each motherboard contains a central processor, random access memory connected to the central processor, a heat sink connected to the central processor, user interface connectors (Application US 2014307386 A1, class G06F 1/16, publ. 16.10.2014).

The task to which the claimed invention is directed is to perform modernization in terms of more efficient use of space in a blade server, which will allow you to perform various configurations by changing the number of components, such as motherboards, expansion cards, hard drives.

The technical result of the claimed invention is to increase the level of computational density.

This functional feature was realized due to the design of the motherboard, the base backplane and the chassis, as well as the specific location of the motherboards relative to each other inside the chassis and the specific location of the expansion cards and hard drives relative to the motherboards.

All of the above components form a single functional unit in which each of its components has a specific location.

The task is achieved by executing a blade server, including motherboards with a central processor connected to random access memory, a heat sink connected to the central processor, connectors for user interfaces; Base backplane expansion cards; hard disks; means of their fastening; at the same time, the blade server is additionally equipped with Mini PCI Express 3.0 Full size interface connectors, SSD drives, while the number of motherboards is no more than four, while the first two motherboards are installed in the base of the blade server enclosure and fixed side by side in the same plane , two second other motherboards are installed and fixed side by side in the same plane, each with a 180 degree rotation around the longitudinal axis to the motherboards at the base of the blade server chassis, the longitudinal axes of the four motherboards are parallel to each other d friend, and the user interface connectors of the four motherboards go to the front of the case; the power and system interface connectors go to the back of the system board, with the motherboards located so that when one board lies in a plane parallel to the plane of the other board and is rotated 180 degrees around the longitudinal axis to the other board, the minimum distance between the data planes is achieved motherboards, and the heat sink of the central processor of each of the boards is located opposite the memory modules of the opposite board and has a relief notch for unhindered passage of the mode her memory without touching the heat sink.

No more than four 2.5-inch SATA3-formatted hard drives are installed in the blade server enclosure.

No more than four SSD drives with an M.2 2280 SATA3 interface are installed in the blade server enclosure.

No more than four Mini PCI Express 3.0 Full size expansion cards are installed in the blade server enclosure.

The operation of the blade server is as follows.

“Blade” - the technology includes the principles of building a system in which the power, cooling, connecting hard drives and network functions are assigned to the external components of the system, used to increase computing density, reduce costs and facilitate the operation of the system.

The blade server consists of several functionally complete and independent from each other servers installed in a single construct. To get started, the minimum configuration requires only connecting a power supply to the chassis with an industrial-standard set of DC supply voltages (5 V and 12 V). Power is supplied through the base backplane (2) to the system boards (3).

Then, 0.9 V is supplied to the central processor (4), and 1.2 V to the memory modules (8).

The base backplane contains a packet microprocessor (not shown in Fig. 1-3), which allows the chassis controller to exchange data with each of the system boards installed in the construct.

Data exchange between the motherboards and the chassis controller is carried out via the IPMB interface.

The blade server is cooled using heat sinks (5) and chassis fans, where it is installed.

Users are connected to the blade server through user interfaces (9) on the front panel (Gigbit Ethernet and 10 Gigabit Ethernet). For the purposes of configuring a blade server by the number of installed motherboards, there are plugs on the front panel.
