Abstract
The utility model discloses a RAID card based on multi -path server belongs to the computer storage field, including RAID control chip, FLASH, EEPROM, NVRAM, PSoC, FLASH storage RAID control chip's firmware ensures the normal operating of chip, the EEPROM storing configuration file, NVRAM saves interim information, avoids information loss, the analytic SGPIO signal of PSoC, voltage information is monitored simultaneously to control LED lamp, the utility model discloses satisfy the demand for control that multi -path server calculated the local hard disk of node pair, compensatied the disappearance that multi -path server singly calculated node local hard disk management scheme, be favorable to the competitiveness of promotion company on multi -path server.
Description
Technical field
The utility model discloses a kind of RAID card, belong to Computer Storage field, specifically a kind of RAID card based on multipath server.
Background technology
RAID card be a kind of polylith independently physical hard disk to combine differently formation logic hard disk, thus provide and have higher performance than single hard disk and the technology of data redundancy is provided.
RAID card is generally divided into hard RAID card and two kinds, software PLC card, be exactly hard RAID by what realize RAID function with hardware, independently RAID card, the integrated RAID chip of mainboard is all hard RAID, is normally made up of a series of spare parts such as I/O processor, hard disk controller, hard disk connector and buffer memorys.Use the RAID card of CPU to refer to use CPU to complete the conventional calculating of RAID by software, it is higher that software RAID takies cpu resource, and most server apparatus is hardware RAID.RAID technique is through constantly development, and occurred RAID rank, different RAID rank represents different memory properties, data security and carrying cost.
Also do not meet the RAID of multipath server computing node to the demand for control of local hard drive at present, the utility model provides a kind of RAID card based on multipath server, for meeting the demand for control of multipath server computing node to local hard drive.By this utility model, the RAID card function of multipath server single node can be realized, meet the demand of enterprise-class tools, compensate for the disappearance of multipath server list computing node local hard drive Managed Solution, be conducive to the competitive power of lifting company on multipath server.
Summary of the invention
The utility model provides a kind of RAID card based on multipath server, for meeting the demand for control of multipath server computing node to local hard drive, compensate for the disappearance of multipath server list computing node local hard drive Managed Solution, be conducive to the competitive power of lifting company on multipath server.
The technical scheme that the utility model adopts is:
Based on a RAID card for multipath server, comprise RAID control chip, FLASH, EEPROM, NVRAM, PSoC, FLASH stores the Firmware of RAID control chip, guarantees the normal operation of chip; EEPROM store configuration files, NVRAM stores temporary information, avoids information dropout; PSoC resolves SGPIO signal, controls LED, simultaneously monitoring voltage information.
Described RAID card is connected with CPU board by PCIE high speed connector, and CPU board provides PCIE signal to be connected to RAID control chip.
RAID control chip sends SAS signal to SAS connector, management hard disk.
Raid control chip refers to the companion chip controlling to perform Raid function, and common is IntelICH5R, VIAVT8237, SIS964, nVidianForce3250GB etc.
The beneficial effects of the utility model are:
The utility model provides a kind of RAID card based on multipath server, comprises RAID control chip, FLASH, EEPROM, NVRAM, PSoC, and FLASH stores the Firmware of RAID control chip, guarantees the normal operation of chip; EEPROM store configuration files, NVRAM stores temporary information, avoids information dropout; PSoC resolves SGPIO signal, controls LED, simultaneously monitoring voltage information; The multiple local hard drive of ALARA Principle, realize the functions such as RAID0, RAID1, RAID6, RAID10, meet the demand for control of multipath server computing node to local hard drive, compensate for the disappearance of multipath server list computing node local hard drive Managed Solution, be conducive to the competitive power of lifting company on multipath server.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
Fig. 2 the utility model signal connection diagram.
Embodiment
With reference to the accompanying drawings, by embodiment, the utility model is further illustrated:
The utility model Raid control chip refers to the companion chip controlling to perform Raid function, can adopt common Raid control chip, also can independent research.
Based on a RAID card for multipath server, comprise RAID control chip, FLASH, EEPROM, NVRAM, PSoC, FLASH stores the Firmware of RAID control chip, guarantees the normal operation of chip; EEPROM store configuration files, also manages the information such as PHYMAP; NVRAM stores temporary information, avoids the information dropout because power-off etc. causes; PSoC resolves SGPIO signal, controls LED, simultaneously monitoring voltage information;
Described RAID card is connected with CPU board by PCIE high speed connector, and CPU board provides PCIE signal to be connected to RAID control chip, can provide 100M clock and I2C signal simultaneously;
RAID control chip sends SAS signal to SAS connector, management hard disk; RAID control chip also sends signal and communicates with UART with EJTAG and to debug for chip DEBUG.
