You are correct that the meta stripe is 960k, and there are 12 tracks on a 3+1 RAID set, which is 384k (32k tracks on DMX1/2 and 4 tracks on 3 data drives)  If a striped meta was to be created on top of this, it should be across more than one raid group, so there is no worry about wrapping.
Hi,  I'm a little confused with Meta/Hyper stripe size's on a DMX 1000. After doing some research the default (and apparently best) meta stripe size is 960k. On a fairly standard RAID5 (3+1) hyper, i'm trying to understand exactly how the data will fall. Presumably for 3+1, the stripe of the RAID would need to be greater or equal to 320 (960 divided by 3) in order to prevent wrap around.  However when I look at my standard RAID 5 (3+1) hypers, they seems to suggest their stripe size is "4 tracks". 4 Tracks * 128 * 512 /1024 = 256k stripes. 256k * 3 = 768k which is obviously short of the 960k meta stripe size. To me this would seem to suggest that within a hyper, when you get towards the end of the 960k stripe, it will start hitting the first disk member in the hyper again? Surely this cannot be correct.  Are my numbers wrong somewhere?  Many thanks
