Hi James,
Cisco Learning has decided to take data centric approach. What this means is all the product specific training courses are being retired one by one and are getting merged in to wider technology specific area like Data Centre is one as an example. Certification and training courses like DCUFI, etc includes Nexus and MDS products training and certifications.
As a result, Cisco learning has decided to retire DCSNS, ICSNS, IASNS and CCIE Storage Networking as well by the end of Q2CY13.
To cover up the MDS specific trainings, we are now focusing on DCMDS which is specific to MDS products. This course is available now with 9222i platform and will be updated soon to include new platform - MDS 9710 (and 9250i at a later stage). The approximate timeline we estimate for this course update to be rolled out to all of our training partners is around Q3CY13 time frame.
So, if you are looking for MDS specific training course for storage experts, DCMDS is the way to go. It covers all the indepth details and is appropriate for new starter in SAN or experts in SAN as well.
Hope this answers your question.
