Cisco not getting rid of MDS 9500 Storage Director in favor of the Nexus 7000

Douglas Gourlay - Cisco Data Center Business Unit Senior Director of Marketing and Product Management, confirmed that Cisco is not getting rid of the Cisco MDS 9500 Storage Director in favor of the Cisco Nexus 7000 in his recent Cisco Data Center Blog entry: FCoE, FibreChannel, Ethernet, Eagles, and Parrots Gourlay opines that: FibreChannel is here to stay.

I can guarantee 10 years from now FibreChannel will still exist, and still be deployed actively in our customers networks. It's a good protocol, it works, it works well, and it will continue to solve some network problems that even by that time I do not think Ethernet and FCoE will have evolved to deliver. Customers that I have talked to really don't like changing their network equipment out every 2-3 years, most like equipment that has legs. FCoE will happen. Of this I am certain. But I also believe that the pragmatic adoption path of FCoE will be first on the host, then over a period of time switch to switch, and then eventually to the target. Why?

1.	Hosts get churned faster than Targets.
2.	By running FCoE to the hosts more workload processing capability gets connected to the SAN. This means there is more data to protect and safeguard. This is GREAT for storage. The entire Storage market is predicated on 15-20% of the hosts connecting to the SAN. Fast-forward 3-5 years and imagine a world with 100% of the servers connected to the SAN. Pretty powerful!
3.	Existing SAN services that Cisco has integrated into the MDS* like Storage Virtualization, Encryption of Data at Rest, and Data Migration can get applied against all the corporate data in the FC SAN.*
4.	For Cisco customers, uniquely, this lets their existing MDS infrastructures* continue to soar and interconnect with FCoE for host-access to the SAN.*
5.	Cisco is continuing to invest in R&D for the MDS 9500 series, delivering on a strong roadmap of innovative products that continue to lead the market in services, stability, investment protection, etc. (Will we get to 8Gb and such? Certainly, the MDS is already shipping 10Gb, if you can do 10Gb, I assure you you can do 8Gb ;) But we felt it was also important to not require yet another director* to get there.*

If another director won't get there, what will get there?
