El Reg has a quick overview of the upgrades to EMC's Symmetrix VMAX. Some of it is good stuff:
The Fibre Channel upgrade doubles link speed from 4 to 8Gbit/s and EMC has also announced 8Gbit/s mainframe FICON links and 8Gbit/s SRDF (Symmetrix Remote Data Facility). It has added support for the mainframe zHPF (z mainframe High Performance FICON) protocol which EMC says streamlines the FICON architecture to reduce I/O overhead and improve mainframe performance.
The 8gig ports for remote replication are more of an upgrade incentive than an enticement to convert, but that makes it harder for the competition to steal EMC customers.
