We will make a few rough calculations in this section. If possible, obtain data regarding the amount of CPU cores, available RAM, and the number of disk spindles in the storage pool.
Linux systems have a live filesystem that tracks most of this information. To obtain the number of CPUs, simply execute this at the command line, and add one to the highest value since indexing starts at zero:
grep ^processor /proc/cpuinfo
For the amount of RAM in kilobytes, use this command:
grep MemTotal /proc/meminfo
Finding the amount of disk spindles can vary greatly between RAID and SAN implementations, so we suggest you obtain the number from the infrastructure department.
