Ethernet data center switch to take on Cisco Nexus
Infiniband vendor Voltaire took a big leap into the Ethernet data center switching arena with a core switch optimized for virtual environments and Layer 2 efficiency.
Voltaire’s first Ethernet switch, the Vantage 8500, is the embodiment of the company’s “Scale-Out Ethernet” data center architecture. The switch features a 12-slot 11.5Tbps chassis with a peak slot capacity of 960Gbps.
Initially, the Vantage 8500 will support 288 nonblocking 10G Ethernet ports, with future plans to accommodate 432 and 576 10G Ethernet ports with higher density line cards. Current Line card options include 24 port 10G Ethernet SFP+ nonblocking; 36 port 10G Ethernet SFP+; and 20 port 10G Ethernet plus eight port FibreChannel, which will come next year.
The switch supports the imminent Converged Enhanced Ethernet specifications from the IEEE, FibreChannel over Ethernet, Voltaire’s virtual switch fabric and I/O techniques, latency of less than 1 microsecond and less than 10 watts of power per port, Voltaire says.
Up to 12 Vantage 8500s can be clustered together to connect up to 3,400 servers, Voltaire says. It interoperates with standard Gigabit Ethernet and 10G Ethernet switches, and provides “fabric wide” congestion management and QoS, the company says.
Voltaire says the Vantage 8500’s congestion control and routing optimization silicon can detect and avoid impending congestion rather than react to it. Its patent pending Virtual I/O Port Objects (VIPO) technology, which the company says is “aligned” with Virtual Ethernet Bridging work in the IEEE, partitions each switch port into multiple independent virtual ports so they can be provisioned, monitored and mirrored as if they were physical ports.
VIPO policies can migrate across physical ports, Voltaire says.
Fabric virtualization allows the switch to be partitioned into virtual data centers. Each virtual data center consists of physical or virtual servers, with isolated virtual I/O to storage and network resources, Voltaire says.
Servers can dynamically change and move while policy and SLA is maintained, and user access can be restricted to a virtual data center, the company says.

Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.
