Description

Based on the disk position hot plug mainboard server of 2U cabinets Gemini 20

Technical field

The utility model belongs to server apparatus field, especially a kind of to be based on the disk position hot plug master of 2U cabinets Gemini 20 Plate server.

Background technology

The network in China is become increasingly popular at present, and the new technology such as cloud computing and big data is greatly developed, personal standby to data Part, enterprise are to the demand of data platform etc., it is necessary to use substantial amounts of storage server.

In the process of running, hard disk is in constantly data storage, and the data capacity for working as hard-disc storage reaches for storage device , it is necessary to be changed or safeguarded to hard disk during certain size；Storage cabinet inside is generally fitted with multiple hard disks while transported OK, the normal operation of other hard disks can not be influenceed by changing or safeguarding during some hard disk, this just needs hard disk to support hot plug, i.e., hard Disk needs to support independent power-on and power-off and does not influence other hard disks；

Existing traditional storage system is substantially based on SAS/SATA interfaces, by SAS Controller and Expander chips reach the storage system of the multiple hard disks of mainboard control to extend.SAS master at present Stream or using the 6.0Gbps of SAS 2.0 the 12Gbps of the SAS 3.0 and 6Gbps of SATA 3.0 speed.And in hard disk speed Defect has not caught up with the growth requirement of industry gradually.

NVMe SSD appearance alleviates the bottleneck in present hard discs speed, and NVMe SSD are using the X4's of PCIE Gen 3 Signal, the read-write of data is directly carried out to NVMe SSD using CPU, substantially increase the efficiency of disk read-write.

Existing two-way storage server cabinet hard disk all uses SATA or SAS hard disks, speed cannot with it is current before NVMe SSD speed is mentioned in the same breath.We use test comparisons of the NVMe SSD with common SATA SSD IO performances, from That 512K orders are read it can be seen that coming, NVMe SSD can reach 2600, and common SSD speed only has 500, therefore NVMe The performance that SSD 512K orders are read is as many as 5 times of common SATA SSD.And above the performance of 512K sequential writes from the point of view of, The performance of NVMe SSD 512K sequential writes is 1200, and common SATA SSD performances only have 200, therefore NVMe SSD 512K The performance of sequential write is as many as 6 times of common SATA SSD.This this test comparison can be seen that current NVMe SSD speed Degree advantage is very clear and definite.

NVMe SSD are read and write into delay with common SATA SSD to compare, it can be seen that NVMe SSD read-write is prolonged from contrast When probably only have common SATA SSD read-write delay 1/36.Additionally by test checking observation, SATA SSD read-writes delay is very It is unstable, and NVMe SSD when delay is very stable.

For this reason, it is necessary to design a kind of new modularization storage server, NVMe SSD can be introduced into server, So as to improve processor efficiency.
