Sure,  In either Symmetrix model, take your 8 DAEs and divide that into the 96 min.  That gets you 12 per DAE.  Technically we need only 4 per DAE for the cache vaulting (to give a total of 32), but the 96 provides for better back-end drive performance and hyper volume distribution in your RAID protection schemes for the logical volumes you provision.

Hi             This question is related to DMX-4  backend cable connections and number of drives that can be connected .  From document , we can get that  if we have 2 disk director/adapter  we can connect min. 96 and max. 240 drives.  I know that disk shelf can contain min. 4 disk amd max. 15 disk .   1) How many ports are there in a disk adapter  2) How the cable connection done for this case  Can somebody explain the min. and  max . drives number and how they will be connected ..   I have never get a chance to see the rear side of a symmtrix .. [IMAGE]  Thanks Bipul
