Australian Curtin University of Technology is one of the first beta customers to sign up to a telecom provider ’s new private cloud-based service which utilises technology from Cisco, EMC and VMware and is also currently deploying an internal private cloud, based on the Cisco Unified Computing System – An interesting journey to the cloud presented by the Curtin University of Technology’s CIO, Peter Nikoletatos as described by Cisco Linda Horiuchi in her blog
if you want to know more about the deployment of this University at the forefront of the cloud computing adoption, listen to the roundtable organized with the systems integrator (Alphawest),the telecom provider (Optus Business) and the vendor partners (Cisco, EMC and VMware) in addition of Peter Nikoletatos
Two of our favorite bloggers, Kash Shaikh and Omar Sultan wrote several times on the emergence of the FCoE solution, and the benefits of the unified fabric approach
Today Kash Shaikh and Senior Director of IT Derek Masseth at University of Arizona talk about how customers are simplifying data centers with new FCoE Solution and how consolidation, simplification and virtualization with unified fabric contribute to more business agility, significant cost reduction and investment protection in the existing customers infrastructures
For those of you who want to know a little bit more about Derek Masseth’s experience with FCoE and Nexus deployment here is the on-demand link for a 20 minutes presentation he made last September
If you look at history, cabling infrastructure has generally been in place ahead of network adapters and switches. That was certainly the case when the market transitioned from 10/100 to 1Gigabit Ethernet. And BASE-T technologies using twisted-pair cables have been the volume leader during each transition.
Same thing is happening here today with 10GBASE-T, short for 10Gigabit Ethernet over twisted-pair cables. 10GBASE-T can utilize the widely deployed Cat6, 6A or 7 cable plants.
But wait, why would anyone need 10G in the data center?
So, lets take a closer at OTV and how it works. As a reminder, OTV is an NX-OS feature that allows us to extend Ethernet LANs between data centers. One of the nice things about OTV is that it is transport agnostic–the connectivity between data centers can be L2 based, L3 based, IP switched or label switch–pretty much anything that can transport IP.
OTV works by creating an OTV control plane through authenticated links between the Nexus 7000 switches at each of your data centers (called edge nodes in OTV parlance). You can then “route” your LAN traffic by encapsulating it and routing it through this IP infrastructure. Routing of the traffic is determined by associating a MAC address with a next-hop IP address. The process is fully dynamic, so there is no need to establish and manage tunnels and virtual wires. This approach certainly simplifies management and administration over existing approaches, but it also allows you to take full advantage of your IP core such as optimal routing and features such as load balancing, multicast traffic replication, and fast failover.
In their Q4 2009 WAVE report Forrester recognized Cisco WAAS as a market leader in WAN optimization in their comparison of the top 8 vendors, considering criteria such as the offering, strategy, market presence, and technology.
Forrester says that WAN optimization is increasing in importance to IT organizations and that business issues such as consolidating branch office servers and rolling out new collaborative applications are driving its adoption. This is because companies rely on the WAN for delivery of their business-critical services, but the WAN suffers from poor performance because of latency over distance.
Forrester advises that WAN optimization technology plays a critical role in improving application performance by using techniques such as caching, protocol optimization, compression, traffic management and quality of service (QoS), to increase effective throughput and mitigate latency, while providing visibility into the traffic mix.
