Description
Technical field
The present invention relates to the performance verification technical field of SAN storage system, be specifically related to a kind of SAN storage system host link bandwidth authentication method, provide a kind of calculating SAN storage system host link bandwidth method, verify the data transmission bauds of SAN storage system effectively and accurately, greatly enrich network bandwidth authentication techniques.
Background technology
Along with the development of Internet technology, huge network client produces the data message of magnanimity every day, and therefore, people constantly increase for the demand of data storage aspect.Now, not only data storage capacity exponentially is increased, and further requirement is proposed to all many-sides of the performance, fail safe etc. of memory device.
Under the promotion of huge storage market demand, memory technology develops from traditional storage organization centered by main frame to the network storage.In Network storage technology, provided Information Access and the share service of network information system by the network storage equipment, its principal character is embodied in super large memory capacity, the large aspect such as data transmission rate and high system availability, remote backup, long-distance disaster.
Existing three large mainstream network storage modes are DAS(Direct Attached Storage respectively), SAN (storage area network) and NAS(network attached storage).Wherein, storage area network SAN provides block stores service, and optical-fibre channel is particularly suitable for SAN storage networking, is present most widely used FC-SAN storage networking.But, because the cost of optical fiber is higher, along with Ethernet bandwidth improve constantly and people to the demand of more large bandwidth, SAN storage networking has had again IP-SAN, IB-SAN two kinds of memory modules.
Generally speaking, after SAN storage networking has been built, people need the data transmission capabilities of the network verifying storage system.In fact, directly from (as optical fiber) transmission line medium, the transmission speed of measurement data is very complicated, and acquired value is often inaccurate.For this reason, people are by installing scsi-target software respectively at server and disk array end, by the Disk Mapping of disk array end to server end, mapping hard disk as server uses, the now file copy speed of local hard disk and mapping hard disk, as the data transmission bauds of storage system.
Above-mentioned authentication method is accurately for the data transmission bauds checking of IP-SAN, FC-SAN storage system, but but differs greatly for the checking of the data transmission bauds of IB-SAN storage system.
As shown in Figure 1, this figure is for SAN storage system, adopts the method for physical disk mapping mechanism checking memory system data transmission speed.The method installs scsi initiator software at server end, and install scsi target software at disk array end, the Disk Mapping of disk array end uses to server end after connecting by both.When server adopts gigabit Ethernet to Disk Array Host link, this file copying speed can reflect host link bandwidth, but when the band of host link is wider than Magnetic Disk Controler bandwidth, the method cannot measure SAN storage system host link bandwidth, the inconvenient debugging to storage system host link section path performance.
Summary of the invention
The technical problem to be solved in the present invention is: the object of the invention is to the deficiency overcoming existing verification method, proposes a kind of SAN storage system host link bandwidth method, effectively can verify the data transmission bauds of storage networking.
The technical solution adopted in the present invention is:
A kind of SAN storage system host link bandwidth authentication method, described method reflects host link bandwidth by carrying out large files copy between server and the internal memory of disk array.
The general principle of the method is, between internal memory, the transmission speed of data is greater than host link transmission speed, and transfer of data is without Magnetic Disk Controler, in data transmission procedure, file copy limited speed between internal memory is in the host link bandwidth of SAN storage system, measuring the file copy speed of virtual hard disk and mapping hard disk, is exactly the host link bandwidth of SAN storage system.
Described method operating process is as follows: first at server end, adopt RamDisk instrument internal memory (RAM) to be invented disk to use, at disk array end by memory-mapped to server end, use as disk, then by verifying the file copy speed of virtual disk (local memory is virtual) and Map Disk (disk array mapping), the data transmission bauds of storage networking is reflected.
The operating procedure that described method is concrete is as follows:
1) at disk array end, target software is installed;
2) dd order is used at disk array end, by under memory-mapped to/tmp/disk file directory, and as the rear end memory device of vdisk_fileio pattern;
3) host server end installs initiator software;
4) use RamDisk instrument, memory-mapped is become local virtual disk, and connects the remote dummy disk of disk array end;
5) after configuring above step, at server end, be the file of 4G from local virtual disk toward remote dummy diskcopy size, use HDTune to monitor the writing speed of remote dummy disk, the copying speed of this file is exactly the host link bandwidth of storage system.
Beneficial effect of the present invention is: the invention solves and cannot measure SAN storage system host link bandwidth, with the problem of inconvenience to the debugging of storage system host link section path performance, host link bandwidth is measured by carrying out large files copy between server and the internal memory of disk array, verify the data transmission bauds of SAN storage system effectively and accurately, greatly enrich network bandwidth authentication techniques.
