Description
Context: Windows nature connection of EOS-wnc to Windows operating system.
Objectives: The connection of the EOS-wnc on Windows platform should be as it is for Windows local disks, external disk storages, it means as a Windows disk driver letter.
Method: A storage on Windows operating is presented as a “disk drive letter”. Architecture of Windows storage drivers has following layers as follows:
- IRP for Upper-filter driver
- IRP for Storage-class driver
- SRB for Lower-filter driver
- SRB for Storage port driver
- SRB for Bus-specific commands
where
IRP (I/O request packets): kernel mode structures that are used by Windows Driver Model (WDM)
SRB (SCSI Request Block): SCSI command descriptor blocks (CDBs)
For EOS-wnc is implemented “thin” Windows disk driver.
Result: Windows driver software is low-level software and bugs in low-level software can be extremely painful; bugs can cause a loose of all data on disk drive including operating system. Therefore, the EOS-wnc Windows drivers implementation is a “thin driver” to maximize stability and security of this part of software.
