Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.
For a better understanding of the present application, embodiments thereof are explained in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a management network device for storing products according to an embodiment of the present application. As shown in fig. 1, the management network device in this embodiment mainly includes: the system comprises a first management network card, a second management network card and a controller. The first management network card and the second management network card are identical in structure and redundant to each other, and are respectively connected with the controller, so that the controller can be accessed through the first management network card or the second management network card. And under the normal condition, the first management network card is adopted by default, and the second management network card is a standby management network card. When one management network card fails, the other management network card is automatically switched to, so that the first-level redundancy is realized.
As can be seen from fig. 1, in this embodiment, the first management network card and the second management network card both include: the system comprises a first user network interface, a second user network interface, a south bridge chip and a switching chip. The first user network port and the second user network port are respectively connected with the south bridge chip, two cables are arranged between the south bridge chip and the exchange chip, the two cables are redundant, and the exchange chip is connected with the controller.
In this embodiment, the first User network port and the second User network port are U ports, which are also called User ports, that is, network ports used by users. The number of the controllers can be 1 or more than or equal to 2. Taking 2 controllers as an example, a schematic diagram of an internal link of a management network device for storing products in the embodiment of the present application may be shown in fig. 2. In fig. 2, the management network card 1 and the management network card 2 are respectively: a first management network card and a second management network card. The ETH U0 and ETH U1 are interfaces of a first user network port, a second user network port and an ETH T port, namely PCI-E respectively. PHY is south bridge chip, the type of the south bridge chip is: BCM5482, SerDes SW for the switch chip, the switch chip model adopted is: BCM 5389.
As shown in fig. 2, in the present embodiment, the first user port ETH U0 and the second user port ETH U1 are respectively connected to the south bridge chip BCM5482, two cables are disposed between the south bridge chip BCM5482 and the switch chip BCM5389, the two cables are redundant to each other, and the switch chip is connected to the controller.
Taking the management network card 1 as an example, the management network card 1 may respectively manage the first controller and the second controller through paths 3 and 4, and the two management network cards form a primary-standby switching relationship.
The redundant path from the management network card 1 to the controller 1 is: 1-2-3 and a-B-3, the redundant paths from the management network card 1 to the controller 2 are: 1-2-4 and a-B-4, and the four redundant paths pass through PHY chip 5482 and switch chip 5389 in between. Therefore, the connection mode of the first management network card and the second management network card can realize link redundancy, namely second-level redundancy, in the first management network card or the second management network card.
When the management network card 1 fails, if only the link failure in the internal part of the management network card occurs, the management network card can be communicated with the corresponding controller by switching the redundant path. When the management network card 1 is in a fault, the management network card 2 is switched to through the main/standby switching relation, and the management network card 2 respectively manages the first controller and the second controller through paths c and d. Therefore, in this embodiment, physical isolation and redundancy can be achieved through the first management network card and the second management network card, redundancy of two paths can be achieved inside a single management network card, and through two-stage redundancy of double-link paths in the double management network card and the management network card, reliability of a management network can be greatly improved, high reliability and high availability of the management network are achieved, and thus user experience is improved.
As can be seen from fig. 2, the first Management network card and the second Management network card further include an ETH (Ethernet) T port, that is, a BMC (Baseboard Management controller) Management port, in addition to the U port, and the ETH T port is connected to the switch chip through another south bridge chip. The south bridge chip in this embodiment is a south bridge chip in the first management network card or the second management network card for connecting to the user network port.
Further, in this embodiment, the management network device is connected to the storage product through a backplane.
The present application also provides a storage system, including: storing products and managing network devices. The storage product and the management network device are connected through a backplane, and the management network device is a management network device for the storage product as described above, and is not described herein again. By arranging the management network device, the whole storage system can realize the primary redundancy of two management network cards and the secondary redundancy of the internal path of each management network card on the U port, thereby greatly improving the reliability and the availability of the whole storage system.
