Disks required to store a core dump

When the filer creates a core dump, it saves the contents of memory and nonvolatile RAM (NVRAM) to a set of fixed-sized areas at the beginning of all the disks. Therefore, you must make sure that the filer has enough disks to create a complete core dump for the amount of memory and NVRAM it has.

The minimum number of disks needed for a successful core dump is shown in the following table.

Memory	NVRAM	4-GB disks	9-GB disks	18-GB disks	36-GB disks	72-GB disks
512 MB	32 MB	6	3	2	2	1
1 GB	32 MB	12	6	3	3	1
3 GB	128 MB	n/a	18	9	7	2
