Hi guys, today i got my PowerValut220, while configuring i got a few questions where i will need help from you guys 1- write policy: write throug/write back This machine is hosting database for site which is read intensive (this is dedicated DB server), and while doing some research i read from a site that "write throug" will be good for fast read. What you guys suggest. 2- read policy: no_readahead/readahead/adaptive No idea about this, what is recommended? 3- cache policy:cachecd io/direct io same no idea for this what is suggested? All feedback are welcome. Waqar.
