Thaks to : Sven Heydecke Grzegorz Bakalarski Przemol Summary : --------- As the 3510FC and the original-branded Dothill Sannet II FC are using the Infortrend Eon2510 controllers, stripe size with the last recent firmware releases should be as following: RAID 0, optimization for sequential I/O: 128k RAID 0, optimization for random I/O: 32k RAID 3, optimization for sequential I/O: 16k RAID 3, optimization for random I/O: 4k RAID 5, optimization for sequential I/O: 128k RAID 5, optimization for random I/O: 32k When I do remember right, the optimization for random I/O will only work for logical drives (RAID sets oder LUNs in speech of others) with size smaller than 512 GB - this is due to limitations in Infortrends internal organization of RAID controller's architecture (as well as the limitation to logical drives of 2 TB in size) This limitation is solved and a new functions like individual stripe sizes on a per logical drive basis are implemented with firmware 3.31 and above. Since at least Sun's (and Dothill's?) notation on f/w release versions is sth. different, there's maybe a chance that the 3.31 release is already available from Sun ... _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Sun Feb 8 20:50:37 2004
