Abstract： |
This invention belongs to the SAN technology field of storage area network, the character is: it organizes the frontal server in SAN and excrescent DRAM memory resources in the object node server together to form a high speed virtual hardware TH-SSD, and gives users the same read-write connect of normal disk. This method uses virtual technology to project the primary dispersive memory resources to a continuous virtual disk address spaces, all the data requests to TH-SSD from front are the request to virtual disk. Factually, it expends the usable virtual disk spaces because of using expending memory technology of X86 platform; and it ensures date integrality in TH-SSD because of using the image strategy with double log and double copy; and it realizes the no gap supporting to FC SAN and IP SAN, and makes TH-SSD can good work not only in fiber-optic network, but also in Ethernet. |
