IBM says we cannot expand our physical memory on our 570's without upgrading all the existing DIMMS since all slots are currently full. Is it really so difficult for IBM to build servers that leave a couple vacant slots for future expansion? A technical explanation would be greatly appreciated.... (2 Replies)

ns_rand
ns_rand(3aolserver) AOLserver Built-In Commands ns_rand(3aolserver)
__________________________________________________________________________________________________________________________________________________
NAME
ns_rand - commands
SYNOPSIS
ns_rand ?max?
_________________________________________________________________
DESCRIPTION
ns_rand generates a cryptographically-secure random number. If max is not specified, the random number is a floating-point value n such
that 0.0 <= n < 1.0.
If max is specified, it must be a positive integer between 0 and 2147483647. The return value is an integer value such that 0 <= n <= (max
- 1).
Internally ns_rand is implemented with the drand48(3) and lrand48(3) standard library functions. An internal random seed is generated the
first time ns_rand is called after the server starts.
EXAMPLES
nscp> ns_rand
0.39938485692
nscp> ns_rand 10
