Description
Technical field
The utility model is related to Information Technology Equipment field, more particularly, to a kind of switch based on NVMe SSD.
Background technology
Switch is the important composition link of Information Technology Equipment, traditional switch guiding file, system map file,
Manufacturer's configuration file etc. is deposited in FLASH, with switch operation system image increase and the technology such as SDN is brought to friendship
Change planes the demand of memory space, part manufacturer switch begins to use SATA SSD to realize the function that FLASH completes.
In traditional storage architecture, the bandwidth of SATA and SAS interface becomes the maximum bottleneck of flash memory I/O, in order to solve this
One bottleneck, is arisen at the historic moment based on the SATA Express of PCIe bus, SATA Express do not have any SATA link layer and
, therefore there is not any transmission transit loss in transport layer, NVMe standard is exactly a kind of physical layer design of SATA Express
Specification.NVMe standard pin defines optimized register interface, instruction set and function collection to PCIe SSD, and provides expansible
Interface is to realize the performance potential of SSD technology the present and the future.Compare traditional SCSI, NVMe is in handling capacity, delay, energy
The many aspects such as consumption, compatibility and extensibility all have leading superiority, and NVMe can bring significant performance boost.
NVMe SSD is NVMe hard disk, and NVME is the new transmission standard of hard disk, is to replace present AHCI.NVMe's
Advantage is at 3 points：1st, lower time delay：NVMe has simplified method of calling, does not need to read register during execution order；And
Every order of AHCI then needs to read No. 4 registers, and one meets 8000 CPU cycle of consumption together, thus causing the delay of 2.5 μ s.
2nd, higher transmission performance：The pretty good SATA interface SSD of performance on the market, can reach 32 in queue depth, but this
It is also the limit that AHCI can accomplish.But enterprise-level PCIe SSD high-end at present, its queue depth may reach 128, very
To being 256 can to have given play to highest IOPS performance.And under NVMe standard, maximum queue depth is up to 64000.Additionally,
The number of queues of NVMe also from the 1 of AHCI, improves 64000.3rd, lower power consumption control.
Content of the invention
The utility model is directed to current needs and the weak point of prior art development, provides one kind to be based on NVMe SSD

Chip, wherein, described NVMe SSD passes through processor and described SDRAM interactive communication, simultaneously described processor and described exchange
Chip interactive communication；Switch operating system associated documents, journal file, system management file, expanded function file, upgrading literary composition
Part is deposited in NVMe SSD, and the operating system that switch reads when system starts in NVMe SSD is run in SDRAM, makes
Obtain switch toggle speed and obtain lifting.
Preferably, described operating system associated documents specifically comprise to guide file, system map file, manufacturer's configuration literary composition
Part.
Preferably, switch reads guiding file in NVMe SSD, system image file and manufacturer when system starts
Configuration file runs in SDRAM.
Preferably, the log management of described switch, system administration and expanded function by using NVMe SSD to storage
Medium is written and read operating.
Preferably, the upgrade file of described switch is placed in NVMe SSD.
A kind of switch based on NVMe SSD described in the utility model, compared with prior art has the advantage that
It is：The NVMe SSD that the utility model uses improves a lot than SATA SSD read or write speed, switch operating system associated documents,
Journal file, system management file, expanded function file, upgrade file etc. are deposited in NVMe SSD, and switch system starts
When read NVMe SSD in operating system program run in SDRAM so that the startup of switch, daily record deposit, system pipes
Reason, function execution, upgrading uniform velocity effectively improve, and good stability, are starting what uniform velocity had high demands to switch
Special dimension has very big application space.
Brief description
Accompanying drawing 1 is the schematic diagram of the described switch based on NVMe SSD.
Specific embodiment
For making the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with specific embodiment, right
A kind of switch based on NVMe SSD described in the utility model further describes.
The utility model proposes the switch based on NVMe SSD, switch operating system associated documents, journal file,
System management file, expanded function file, upgrade file etc. are deposited in NVMe SSD.NVMe is read when switch system starts
Operating system program in SSD runs in SDRAM, and switch toggle speed obtains lifting；Switch daily record is deposited, system pipes
Reason, the execution speed of expanded function obtain and are effectively lifted；Switch upgrades speed is effectively lifted.
Embodiment：
The present embodiment is based on the switch of NVMe SSD, and its overall architecture as shown in Figure 1, mainly includes NVMe
SSD, SDRAM, processor and exchange chip, wherein, described NVMe SSD passes through processor and described SDRAM interactive communication,
