jhonovich 0 Posted May 10, 2008 I found an interesting article today on using RAID: http://www.milestonesys.com/UsersGroup/Articles/tips+and+tricks/ViewTips?Id=2340 He's an integrator and the article assumes using a software only solution. One of the things I found interesting is the difference in complexity and cost of setting up RAID for a software only versus an appliance. With most DVR appliances, you simply choose the RAID model and you are all set. I have written a more in depth review on this at: http://ipvideomarket.info/review/show/18 including a discussion on relative pricing. How often do you use RAID in your systems? In my experience, most clients don't use RAID because of the increased costs but I do see that changing with the premium for RAID dropping.

survtech 0 Posted May 10, 2008 In casinos, many DVR systems use separate RAID storage in DAS with each server. Occasionally, you find systems that incorporate internal RAID in a box with encoding and processing fully integrated and a few systems, including Dallmeier and Sanyo, use single-channel recorders with built-in hard drives. We use a modified Honeywell Enterprise DVR system that has outboard 8-channel encoders, four per server, and one or more 24-bay RAIDs attached to each server for storage.

jhonovich 0 Posted May 10, 2008 My understanding is that many casinos have requirements that force the casino to shut the floor down if the DVR is down for more than a certain time period. Have you heard of this? Most of the discussion I hear about RAID comes from the casino (and government) market. I do not hear a lot about other segments using RAID.

Have you heard of this? Most of the discussion I hear about RAID comes from the casino (and government) market. I do not hear a lot about other segments using RAID. Not the whole floor, just the area that is not recording. To somewhat alleviate this, we do not have all cameras in a given area on the same DVR and PTZ's are always on different DVR's from the fixed cameras. That way, we can often "fill in" with one or more PTZ's if we lose one or more fixed cameras in an area. Share this post Link to post Share on other sites
jhonovich 0 Posted May 14, 2008 Thanks. That's really interesting, especially how it effects distribution of cameras to video recorders. Share this post Link to post Share on other sites
