For all databases you can use either a raw partition or a file.
Sybase Adaptive Server supports the database devices on NFS- and CIFS-mounted devices with Network Appliance Filers for storing data. Network appliance filers provide the same performance and data integrity as raw devices. There are no changes needed to the operating system or to Sybase Adaptive Server to use network appliance filers.
NFS mounted devices have been tested on Solaris, HP/UX, IBM AIX, Windows NT, SGI, and Linux.
Choosing a raw partition
Determine which raw partitions are available.
Determine the sizes of the raw partitions.
From the list of available raw partitions, select a raw partition for each device, based on the size recommendations in Table 2-12.
Verify with the operating System Administrator that the partition you have chosen is available.
Make sure the “sybase” user has read and write privileges to the raw partition.
For more information on choosing a raw partition, see
your operating system documentation.
