Abstract
The utility model provides a kind of SAS12GRAID storage card, and belong to server data memory device field, interface is PCIEGen3x8, port is 8 SAS/SATA ports, and the RAID level of described SAS12GRAID storage card is RAID0,1,10,1E, 5,6,50,60, described SAS12G main control chip is SASRoC chip LSISAS1078, described port adopt 4 built-in, 4 externals, described RAID dish figure place supports 256 at the most; Usefulness: a kind of SAS12GRAID storage card has compatible good, the advantage that transmission data are fast.
Description
Technical field
The utility model relates to a kind of RAID storage card, belongs to server data memory device field, specifically a kind of SAS 12G RAID storage card.
Background technology
Along with the develop rapidly of computer technology, the importance of various information data is more and more obvious.For the memory protection of data, it is one of each manufacturer server technology of first developing.The memory protection of data, mainly through to when data on front disk, the backup carrying out various algorithm realizes, in case precipitate disk failures, or the data that other a variety of causes cause can not be accessed, or partial data damages.Data after backup, can after data failure, and the very first time returns to produces on disk, thus farthest falls end loss.
RAID (Redundant Array of Independent Disks) i.e. Redundant Array of Independent Disks (RAID) is the major technique realizing data backup memory.Multiple independent physical disk is combined into a logic magnetic disc by RAID technique in a different manner, thus improves readwrite performance and the data security of disk.Different RAID levels can be divided into: Raid0/1/2/3/4/5/6 according to different algorithms.The RAID mode that employing two kinds is different simultaneously can also be combined into new RAID level, as Raid10/50/60, to meet needs such as disk size, data redundancy or performance of storage system.The utility model, according to above-mentioned technology, devises a kind of SAS 12G RAID storage card, and it is compatible good to have, the advantage that transmission data are fast.
Summary of the invention
The utility model pin provides a kind of SAS 12G RAID storage card, and the concrete scheme of proposition is: a kind of SAS 12G RAID storage card, and interface is PCIE Gen3 x8, and port is 8 SAS/SATA ports.
The RAID level of described SAS 12G RAID storage card is RAID 0,1,10,1E, 5,6,50,60.
Described SAS 12G main control chip is SAS RoC chip LSISAS1078.
Described port adopt 4 built-in, 4 externals.
Described RAID dish figure place supports 256 at the most.
A kind of SAS 12G RAID stores khaki board parameter:
Number of ports: 8 native SAS/SATA ports, MiniSAS HD
Support SAS 12Gb/s & SATA 6 Gb/s, and backward compatible
PCIE interface: Gen3 x8
Buffer memory: DRAM capacity 1GB, dominant frequency DDR3-1600MHz
Use Mini-SAS HD Connectors
Raid level: RAID 0,1,10,1E, 5,6,50,60
Support SSD Read & Write Caching
Support that super cap scheme realizes Cache protection
Usefulness of the present utility model is: to data high speed processing backup protection, supports SAS12G SSD and hard disk; Achieve the data conversion between PCIE3.0 and SAS3.0 agreement; The backup protection of data is realized by Raid algorithm 0/1/5/6/10/50/60 etc.; Data cached protection, adopts super capacitor mode, can accomplish that data efficient is preserved for a long time.
