Problems solved by technology

[0004] However, this RAID card solution can only connect the SAS bus to the hard disk backplane through the SAS connector on the RAID Card, or can only connect to the local system hard disk through other connectors, which lacks flexibility.
In addition, different storage structure design schemes need to redesign or configure different RAIDCards, increasing costs

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0017] figure 1 It is a structural schematic diagram of the RAID card of the present invention. Such as figure 1 Shown, the structure of RAID card of the present invention is:

[0018] The RAID chip is connected to multiple sets of storage buses, where the storage buses may be SAS buses or SATA buses. In a specific embodiment of the present invention, the RAID chip is an example of a chip with 8 ports (port), and the storage bus is an example of a SAS bus, so figure 1 The middle RAID chip outputs 8 sets of SAS buses, of course, it can also be SATA buses or other types of b...

Abstract

The invention discloses a disk array RAID card. The RAID card comprises a RAID chip, storage buses, AC coupling capacitors, a local system hard disk and an external hard drives panel, wherein the RAID chip is connected with a plurality of storage buses; each signal wire in each storage bus channel is connected with at least two AC coupling capacitors, the AC coupling capacitors are arranged on the PCB in a co-lay mode, wherein at least one AC coupling capacitor is connected with the local system hard disk, at least one AC coupling capacitor is connected with the external hard drives panel. According to the method, the bus reuse and the expansion design can be flexibly achieved.

Description

technical field [0001] The invention relates to the technical field of disks, in particular to a disk array (RAID, Redundant Arrays of Independent Disks) card. Background technique [0002] RAID is composed of many cheap disks combined into a large-capacity disk group, and the performance of the entire disk system is improved by using the bonus effect generated by the data provided by individual disks. [0003] In order to manage the disk, the server will insert a RAID card (Card) or integrate the RAID control chip into the motherboard. The control chip on the RAID Card can transfer the peripheral component interconnection standard (PCI Express, Peripheral Component Interconnect Express) to multiple sets of Serial Attached SCSI (SAS, Serial Attached SCSI) or Serial ATA (SATA, Serial ATA) buses to Mount the hard disk backplane of the storage array or the hard disk of the computing board system, and manage different Raid levels according to design requirements. [0004] Howe...
