The technical scheme of the utility model also includes: the SAS line starts from the Raid card, bypasses the side of the storage expansion structure close to the Raid card and the side facing away from the pulling direction of the hard disk backplane, and runs away from the side of the storage expansion structure away from the Raid card. The side is connected to the hard disk expansion card.

The technical scheme of the utility model also includes: a hard disk indicator light is arranged on the front panel of the storage expansion structure. There are hard disk indicator lights on the front panel of the extension, and the status of the hard disk can be observed through the indicator lights.

The beneficial effects of the utility model are as follows: the utility model provides a storage expansion structure suitable for blade servers, which is installed in the rack-type cabinet, and is connected with the server raid card installed in the rack-type cabinet through the SAS line Connect, so that the computing node can recognize the hard disk in the storage expansion structure to ensure the normal operation of the device. The utility model has a simple structure, and can directly replace the card server unit on one side of the half-width blade server with the storage expansion structure, which can effectively save space, and the change of the chassis is small, which can effectively save costs and effectively It realizes the expansion of the storage capacity of the blade server, and has good practicability and market promotion value.

detailed description

The utility model will be further introduced below in conjunction with the accompanying drawings and embodiments.

Meanwhile, since what is described below are only some embodiments, the embodiments in the present application and the features in the embodiments can be combined with each other under the condition of no conflict.

A storage expansion structure suitable for blade servers, the storage expansion structure 1 is installed in a rack cabinet, the storage expansion structure includes a hard disk, the hard disk is installed on a hard disk expansion card, and the hard disk expansion card passes through a SAS The line 3 is connected to the Raid card 5 in the blade server computing node 4, the hard disk is electrically connected to the power board, and the power board is connected to the cabinet.

The hard disk and the hard disk expansion card are installed on the hard disk backplane 2, and the hard disk backplane 2 is installed in the rack cabinet through the slide groove. The storage expansion structure 1 can move with the pulling of the hard disk backplane 2 through the chute, so that the storage expansion structure 1 can support hot swapping. If an individual hard disk fails, the storage expansion structure 1 can be pulled out directly Replace the problem hard drive.

The SAS cable 3 is covered with a protective sheath 31 .

The storage expansion structure 1 includes a SAS cable limiting structure 32 , and the SAS cable limiting structure 32 is installed on the side of the rack-mounted cabinet facing away from the direction in which the hard disk backplane 2 is pulled.

The SAS line 3 starts from the Raid card 5, bypasses the side of the storage expansion structure 1 close to the Raid card 5 and the side facing away from the pulling direction of the hard disk backplane 2, and runs from the side of the storage expansion structure 1 away from the Raid card 5 Connect with the hard disk expansion card.

A hard disk indicator light is arranged on the front panel of the storage expansion structure 1 . The front panel of storage expansion structure 1 has a hard disk indicator light, and the hard disk status can be observed through the indicator light.
