Brocade is putting flesh on the bones of is Virtual Cluster Switching (VCS) architecture that it announced in June with the release of the VDX family of converged Ethernet switches.
At the Brocade Conference 2010 in Frankfurt, Germany this week, the company announced the VDX 6720 models -- a 1U 24-port switch and a 2U 60-port switch -- which let IT build flat, multipath networks that will work in the newest data center architectures. Both switches support 10Gigabit Ethernet and 1Gigabit Ethernet as well as Fibre Channel over Ethernet and iSCSI and file-level CIFS and NFS protocols They also support Brocade's VCS technology, which allows the clustering of as many as ten other switches.
In a virtualized infrastructure where multiple servers are partitoned with VMware, Citrix XenServer or Microsoft Hyper-V, the VCS architecture allows the migration of virtual machines.
Further, the VDX switches support the IEEE Data Center Bridging standards for lossless Ethernet switching. They do not support the Spanning Tree routing algorithm. In accordance with emerging standards, the VDX switches also support TRILL for transporting data across converged fabrics.
All VDX switches are managed from a single management interface and all links are self-healing and changes can be made non-disruptively.
The VDX switches are expected to ship in December but are already for sale through the channel.
Brocade also plans a 48-port switch for early 2011 and a chassis-based core switch for 2011. The VDX switches start at $10,700. The VDX switches are sold on a pay-on-demand licensing model where ports can be added 10 at a time.
