Geez, Tony, if the DS8700 is safe, stable and steeped in the POWER tradition, then why does it not support all the same features as the DS8300 it replaces? <div>&nbsp;</div> Could it be that the POWER microcode is in fact incompatible across processor AND platform generations? Or perhaps you have some other creative excuse why the announcement materials and RedBooks call out that the new DS8700 doesn't support either Thin Provisioning nor Remote Pair FlashCopy as is offered on the archaic DS8300? <div>&nbsp;</div> In stark contrast, the new Intel-based Symmetrix V-Max not only supports all the features offered on the PPC-based DMX3 and DMX4 with inherently compatible management GUI, API and CLI, it also builds upon the proven DMX base with numerous new capabilities and features. You see, properly architected SOFTWARE (as opposed to microcode) is easily ported to a new hardware platform with out compromizing features OR availability. <div>&nbsp;</div> IFF you know what you're doing, that is. <div>&nbsp;</div> Oh, and the fact that there is virtually ZERO shared hardware or software between SVC, XIV and (NetApp's) N Series, not to mention the DS8K, DS5K or DS3K, is surely not lost on the audience.
