Siemens V4.0 manual MaxEASize Regdword 1 infinity, MaxFileSizeInKB Regdword 100 infinity

Advanced Server Registry	Advanced Server Key Descriptions
MappingSeparator REG_SZ	Character string up to 7 characters

Specifies the string that will be appended to the file name before its unique suffix to indicate that the name is mapped. This value matters only in UNIX system to Windows NT file name mapping. The default is a tilde (~), the same as in UNIX system to 8.3 mapping, but it is possible to set it to enable the client to easily identify files containing characters illegal in Windows NT. By default, a file named “my?” will be mapped to “my_~xyz”. When the value of this key is set to “~asu~”, the name will be mapped to “my_~asu~xyz”. If an invalid parameter is placed in the Registry, the MappingSeparator will be replaced by the default value.

Default: ~

You can change the value of this key using the AS/U Administrator.

MaxEASize REG_DWORD 1 - infinity

Specifies the buffer size in bytes that is allocated for extended attributes.

Default: 4096

MaxFileSizeInKB REG_DWORD 100 - infinity

The maximum file size, in KBytes, that Advanced Server will allow a user to create on the server.

Default: 100000

MaxZeroFillInKB REG_DWORD 0 - infinity

MaxZeroFillInKB controls the amount of space in KB that is zero filled when a client performs a zero length write. NT clients use zero length writes to pre-allocate disk space when copying files. On UNIX, disk space is not allocated to an extended file unless it is physicall written to.

Advanced Server has to write physically to the disk and this takes time within one SMB request. Some clients might get a timeout while Advanced Server is allocating the disk space. If a very large file is copied from an NT client to an Advanced Server share and the file sizes exceeds MaxZeroFillInKB, all of the disk space for that big file will not be allocated on the Advanced Server machine.

Default: 50000 (50 MB)

MemoryMapFiles REG_DWORD 0 or 1

Specifies whether the server uses the UNIX system mmap system call to memory map file data into the server's address space for efficiency. File mapping is attempted only for read-only files.

Default: 1 (memory map read-only files)
