How so? I thought DSSD was doing top-of-rack direct-connect acceleration for specific servers. Also recall that it was brutally expensive, and very exotic, but not very feature-rich.
This seems to be more tailored to enterprise storage by connecting to more servers via typical network infrastructure (iSCSI and Fibre Channel). Also looks like it runs the same software as the other Pure boxes, so it provides the software services (compression, dedup, encryption, snapshots, cloning, replication, etc...).
I was not aware that DSSD had matured to this point.
