I am looking at ways to harden my asterisk install to prevent computer related issues from happening. I am concerned about about disk write cache. That seems to be a major source of hard drive corruption on power failure. Hard Drive corruption is simply unacceptable for the 99.999% uptime requirements of my Asterisk install that needs to be as reliable as a proprietary PBX.
Of course I will be using redundant power supplies, raid 1 and use a UPS. None of those things mean much if the power cords accidentally get pulled from the back of the server. Unlikely as it may be I have to consider ALL possibilities. So is disabling the write cache a good way to reduce the risk of hard drive corruption for an Asterisk server? I am not too concerned about the reduced performance/lifetime of hardrives with write cache disabled since Asterisk is not a very write intensive environment. Even with lot's of voicemail going on. Any other recommendations/links for increasing the reliability of Asterisk servers? _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
