Clearly, the size of the buffer cache and the amount of physical memory required per user have a significant influence on system cost. You need to calculate swap space even if you have enough memory to prevent swapping from ever happening. This is because the kernel preallocates swap space for each process before the process begins. If you run out of swap space, processes will fail, even if the system is not doing any swapping. It is recommended that different file systems be used for different data needs.
File systems contain disk blocks, which are made up of disk fragments.
The default sizes are 8K blocks and 1K fragments. Using eight kilobyte disk blocks and eight kilobyte fragments increases performance for access of large files. The -i parameter specifies the number of bytes per inode. This is appropriate for a file system with large files.
