UCS1

As the picture show above, it is the high level architecture which requires to run the entire UCS solution from Cisco. Not necessary every environment will require Nexus 7000, it is meant for large scale networking environment. You may go with various different switches to replace the Nexus 7000 in the picture depend on your requirement. In the current UCS release, the UCS 6100 interconnect fabric will integrate with the MDS 9000 series Fiber Channel environment or others compatible FC switches. This allow UCS blade I/O to be consolidated with CNA with 10Gbps per connection as FCoE.  This had significant reduce the physical cabling requirement per blade chassis.

Server Virtualization & Cloud Computing Model

Posted on September 26th, 2009 in Data Center, Server, Virtualization | No Comments »

What will be the next after the server virtualization with any hypervisor in the market today? Everyone may has a different thought about it when they went through the journey with different experiences. VMware are very focus on the future of cloud and we also notice there are more cloud providers in the market to provide the cloud services to everyone around the world. But it does not convince enough for the enterprise environment to go for public or hybrid cloud at the moment. Private cloud are always considerable for most enterprise environment.

Is virtualization meant everything? Virtualization is not, but it had played the important role in the entire journey. Everyone may had faced different challenges during or after the server virtualization in the data center. The next thing which prompt up after server virtualization will often be I/O virtualization and utility computing model. I/O had become real challenges as server virtualization had increased the total bandwidth require to be allocated per physical servers which may easily contains 30 virtual machines in 1 single server. At the mean time, we often see the FC, ISCSI and NAS are seperated with the Ethernet LAN in data center.  Can we do it better? my answer is Definitely. Plenty of solutions today such as Xsigo or Cisco Nexus are really ready to address the challenges that everyone is facing today through Infiniband or FCoE.

FCoE in the Data Center

Posted on August 23rd, 2009 in Virtualization | No Comments »

FCoE is new today for data center environment, but it will be very soon adopt by most of the users in 2 years time. If we look at the current environment in most data center today, there will be isolated environment of FC connection for Storage and Ethernet connection for networking purpose in every single data center. Cabling management and knowledge require to keep the environment running and organize is becoming more challenging from time to time. Well, with the FCoE technology from Cisco, it will definitely simplify everything for us.
