Recently I had deployed quite a number of EMC SAN with MDS Switches and Cisco UCS, I found tha FC SAN zoning might be a key consideration we may need to take a look for every deployment. This post will more focus on the MDS and UCS 6120 FC Uplink.
Cisco UCS interconnect fabric switches are utilizing FC uplink to allow the Cisco Unified Computing System to get access to the SAN fabric environment.
Here is the architecture diagram you can refer to. In order to make this work, 1st requirement will be the NPIV.

Unified had become a key word today, and what does it really meant for everyone? It is similar as the phenomenal Cloud Computing 2 years ago. We had seen the storage vendor are moving from FC SAN, ISCSI SAN, NAS to a unified storage today. What a unified storage does today are providing all the storage protocol standard in the market in a single box. Vendor such as EMC and Netapp had their Unified storage to support this today and proven to be performing and user are happy with it.
Beside unified storage, we are looking forward for unified computing system for the server compute platform too. Cisco had moved ahead of their competitor to bring this to the world and it is 1 fo the great platform that get attraction and adoption worldwide. Cisco UCS or Nexus 5000 both provide the unified I/O capabilities and allow us to transform the data center architecture today. Beside consolidating LAN and SAN into 1 with FCoE, the more interesting capabilities that get attention by us are the switching capacity.

Recently there are some request from my client who suggested to have their production and DR site to be automated protected and fail over in the event of disaster. VMware SRM seems to be right choice for most of the time, but these clients are decided to bring it to another level of fail over procedure during the DR happen. I am doing some research today and found this interesting topic from Netapp which the Metro cluster suppose to synchronize from production to DR through dark fiber to prevent controller failure, DR or disk corruption.
