Abstract

A switch includes a chassis, a drive bay including a plurality of downlink switch ports that are configured to be connected to a plurality of storage devices, a plurality of uplink switch ports, and an embedded circuit for providing signal switching between the plurality of uplink switch ports and the plurality of downlink switch ports. The drive bay is disposed on a first side of the chassis, and the plurality of uplink switch ports are disposed on a second side of the chassis that is opposite to the first side of the chassis. The plurality of downlink switch ports is embedded in the drive bay.

Claims

1. A switch comprising:

a chassis;

a drive bay comprising a plurality of downlink switch ports configured to removably connect a plurality of storage devices via front-access slots, wherein the drive bay is disposed on a first side of the chassis;

a plurality of uplink switch ports disposed on a second side of the chassis that is opposite to the first side of the chassis; and

an embedded circuit for providing signal switching between the plurality of uplink switch ports and the plurality of downlink switch ports,

wherein the plurality of downlink switch ports is embedded in the drive bay,

wherein the switch is rack-mountable, and

wherein the plurality of uplink switch ports has pinouts providing an Ethernet interface, and the plurality of downlink switch ports has U.2 pinouts.

2. The switch of claim 1, wherein the plurality of downlink switch ports are embedded in the drive bay to connect the plurality of storage devices, eliminating internal connectors.

3. The switch of claim 1, wherein the plurality of uplink switch ports are small form-factor pluggable (SFP) ports.

4. The switch of claim 1, wherein the U.2 pinouts provide a peripheral component interconnect express (PCIe) interface.

5. The switch of claim 4, wherein each of the plurality of storage devices is a 2.5″

small form factor (SFF) drive.

6. The switch of claim 1, wherein the plurality of storage devices are front-access drives pluggable to the drive bay.

7. The switch of claim 6, wherein the plurality of storage devices is solid-state drives (SSDs).

8. The switch of claim 7, wherein the SSDs are Ethernet-attached SSDs (eSSDs).

9. The switch of claim 8, wherein the eSSDs are connected to the switch over Ethernet.

10. The switch of claim 1, wherein each of the plurality of storage devices contains one or more non-volatile memory (NVM) targets.

11. The switch of claim 1, wherein the plurality of uplink switch ports is connected to a plurality of initiators over Ethernet.

12. The switch of claim 1, further comprising a power supply and a cooling fan.

13. The switch of claim 1, wherein the plurality of uplink switch ports is connected to a plurality of external devices compatible with non-volatile memory (NVM) express (NVMe).

14. The switch of claim 1, wherein the plurality of uplink switch ports is connected to a plurality of external devices compatible with non-volatile memory express (NVMe) over fabrics.

15. The switch of claim 1, wherein an NVMe over fabrics (NVMf)-compatible device is inserted into the drive bay.

16. The switch of claim 15, wherein the NVMf-compatible device is a micro-server or a port expander.

17. A switch comprising:

a chassis;

a drive bay comprising a plurality of downlink switch ports configured to removably connect a plurality of non-storage devices via front-access slots, wherein the drive bay is disposed on a first side of the chassis;

an embedded circuit for providing signal switching between the plurality of uplink switch ports and the plurality of downlink switch ports,

wherein the plurality of downlink switch ports is embedded in the drive bay,

wherein the switch is rack-mountable, and

wherein the plurality of uplink switch ports has pinouts providing an Ethernet interface, and the plurality of downlink switch ports has U.2 pinouts.

18. The switch of claim 17, wherein the plurality of non-storage devices comprises one or more of:

a micro-server and a port expander that are Ethernet-compatible.

19. A switch comprising:

a chassis;

a drive bay comprising a plurality of downlink switch ports configured to removably connect to a plurality of devices including at least one storage device and at least one non-storage device via front-access slots, wherein the drive bay is disposed on a first side of the chassis;

a plurality of uplink switch ports disposed on a second side of the chassis that is opposite to the first side of the chassis; and

an embedded circuit for providing signal switching between the plurality of uplink switch ports and the plurality of downlink switch ports,

wherein the plurality of downlink switch ports is embedded in the drive bay,
