It can take our hardware RAID cards upwards of five minutes. We reboot about once a month for kernel upgrades; several months if we're lucky. Meanwhile, a Wheezy desktop with a cheap SSD boots from cold to usable in less than 19 seconds, which is less than the 30 seconds it takes a TCP session to consider timing out. -dsr-
