Raid Battery Backup?

Aug 2, 2012 8:54 AM

Hi.   I'm working through new disk subsystem issues (see links below for reference).  It looks like I have a new issue to address - raid battery backup.

 

My current editing system uses a battery backup.   Other than some issues lately, it's worked well.   I'm getting a new Areca 1882ix raid controller soon.   The question is, do I need a battery backup specifically for the raid controller?  E.g. http://www.newegg.com/Product/Product.aspx?Item=N82E16816151111 Or is a system battery backup adequate?

 

Thanks,

 

Dan.

    Dan,

     

    The BBM, battery backup module from Areca is the most affordable solution. The alternative is something like this UPS: http://www.newegg.com/Product/Product.aspx?Item=N82E16842101294 which is vastly more expensive. If your electricity supply is generally very reliable, the UPS is overkill and the Areca BBM is a good solution. If you are in a region where snowstorms or hurricanes or flooding often take down electricity poles and you are out of electricity with some regularity, then the UPS is the way to go, till you get your own generator started.

    Dan,

     

    Areca BBU's may have an additional benefit for performance. When I used to use 3Ware cards their firmware would allow for the fastest speed setting to be selected without the presence of a backup battery, however, I seem to think that Areca may only allow for some of the speed tweaks (higher levels of write caching) to be set when a BBU (backup battery unit) is present.

     

    BTW I chose to use both system UPS and Areca BBU and I am definitely happy with that choice.
