## Abstract

The present disclosure relates to an integrator for a storage device, a corresponding storage device and a method of manufacturing the same. The integrator comprises a base board comprising a first interface and a second interface; a connector coupled to the first interface of the base board, the connector being connectable with at least one server in the storage device; an input/output (I/O) part coupled to the second interface of the base board and connectable with an I/O device; and a switcher arranged on the base board and adapted to exchange data between the first interface and the second interface to support data transmission of the I/O device or other servers with the server via the integrator.

## Claims

### Claim 1

An integrator (100) for a storage device, comprising:
a base board (101) comprising a first interface (109) and a second interface (110);
a connector (102) coupled to the first interface (109) of the base board (101), the connector (102) being connectable with at least one server (200) in the storage device;
an input/output (I/O) part (104) coupled to the second interface (110) of the base board (101) and connectable with an I/O device (300); and
a switcher (105) arranged on the base board (101) and adapted to exchange data between the first and second interfaces (109, 110) to support data transmission of the I/O device (300) or other servers (200) with the server (200) via the integrator (100).

### Claim 2 (depends on 1)

The integrator (100) of claim 1, wherein the connector (102) is compliant with Peripheral Component Interconnect Express (PCIe) protocol.

### Claim 3 (depends on 2)

### Claim 4 (depends on 1)

The integrator (100) of claim 1, wherein the switcher (105) comprises a plurality of PCIe switch chips.

### Claim 5 (depends on 4)

The integrator (100) of claim 4, wherein the data is exchanged between the PCIe switch chips via a non-transparent bridge (NTB).

### Claim 6 (depends on 1)

The integrator (100) of claim 1, further comprising a heat radiator (107) for dissipating heat for the integrator (100).

### Claim 7 (depends on 1)

### Claim 8 (depends on 1, 2, 3, 4, 5, 6, 7)

A storage device, comprising:
a plurality of servers (200);
a plurality of I/O devices (300); and
an integrator (100) according to any of claims 1-7.

### Claim 9

A method for manufacturing an integrator (100) for a storage device, comprising:
providing a base board (101) comprising a first interface (109) and a second interface (110);
coupling a connector (102) to the first interface (109) of the base board (101), the connector (102) being connectable with at least one server (200) in the storage device;
coupling an input/output (I/O) part (104) to the second interface (110) of the base board (101), the I/O part (104) being connectable with an I/O device (300); and
arranging a switcher (105) on the base board (101), the switcher (105) being adapted to exchange data between the first and second interfaces (109, 110) to support data transmission of the I/O device (300) or the server (200) with the server (200) via the integrator (100).
