It also tends *over time* to redistribute load more evenly over the physical disk farms -- assuming that you have a sufficiently large number of volumes and disk subsystems so that you're not totally oversubscribed at the start and you have groups/pools defined with disk in different subsystems. There's some risk management benefit too; data gets moved around to different places, which can reduce the impact of a failure. DIRMAINTs disk allocation algorithm works pretty well, albeit these days we're typically talking about full volumes so there's not that much placement optimization going on at a micro level. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
