Continuous Updates

The Entire World is Your Data Center - Today the compute model is reversed. The Customer Experience Comes First. Users can connect from anywhere from anything. As a result compute power and to a lessor extent storage capacity have move from the data center to the end nodes of the network. The entire world is your data center. The network has evolved from where it was 30 years ago with one vendor. Now there are multiple vendors and users have most of the power

Brocade One - enabling a converged environment. Unified view. Where the entire world is you data center. Invention is creating something, Innovation is people adopting it. The driving factor in the move from invention to innovation is simplicity. Also Brocade has a history a supporting multiple server suppliers, storage suppliers, virtualization vendors.

Why shouldn't you do it? Storage is designed for non-blocking connectivity. It is very deterministic. IP networks are not. There is a relatively complex design issue of testing now two different networks. This is going to be a five year or more phase. As customers begin to get into it they realize that it is not trivial. 

Market trends 2009

  1. Bullet Physical Servers down 17% year over year. Belief is that this is an impact of virtualization - Gartner

  2. Bullet 14% increase in fibre HBA shipments year over year. Despite all the IP based storage. - Dell'Oro Group

  3. Bullet 133% increase in CNA port volume - Gartner

  4. Bullet 2009 2.7 M FC ports / 25k FCoE ports - Dell'Oro Group

In summary the moved to converged storage will move slower than we are predicting but we are under predicting its long term impact.

Virtualization, cloud and convergence - perspective is not always reality.Virtualization is a technology that is driving the adoption of cloud. 

Convergence 2.0 - Convergence voice, data and video was convergence 1.0, convergence 2.0 is merging storage on to that network. Easier to draw on the slide then to execute. We have to ask ourselves why should or shouldn't I converge. Are there compelling reasons to go slow? How many people are really doing this? 

Why should you converge? Too many cables. Blade servers have 15 to 20 connections coming out of them. More connectivity in to a smaller space is causing a problem Converged networking then moves to this a single pair of fibre 10GB connections.

Building the Virtual data center

The Dawn of the Virtual Enterprise. Obvious trends, growth of data and virtualization. More subtle trend, the distribution of compute power, started with Mini’s, then PC’s and now mobile devices and cell phones. iPhone example. Pictures taken and then uploaded somewhere in the cloud. Massive storage growth.

Cloud Implications. Many definitions. Public cloud is Applications for rent, infrastructure for rent, platforms for rent. Have to be able to scale environment. No warning that scale is coming. Similar needs are driving private cloud, need to scale quickly and easily. Moving from physically allocated to virtually allocated infrastructure.

Legacy mode was to replicate the data center a server at a time until you ran out of apps. Resulted in 15% utilization and 85% operating costs. Needs to stop  and virtualization is the answer. About 20% virtualization now. This is driving the need for faster bandwidth but it is also driving complexity on the network. Not fixing the operating costs.

To drive down this complexity is going to need to be simplified...flattened. If you move a VM the network should know how to fix all the connectivity. To get there they are innovating in three key areas. Infrastructure systems via a virtual access layer, VCS will allow them to collapse and automated the network and then finally to be and advisor of the elements in the network.

Building the Virtual data center

Virtual Access Layer - Logical construct that extends network connectivity to VM’s. They support third party adaptors but you can get more control with Brocade’s adapters. SR-IOV is coming in Q4. Important for Hypvisors and IO Virtualization.

Virtual Cluster Switching - First data center ethernet fabric. Means high performance, no latency, all links are on. Goodbye spanning tree. Deterministic. It will auto heal on switch failure. Lossless. Built for convergence. First shipment will support 10,000 VM’s!.

Fully distributed control plan. Can be wired up in any topology, they are self-forming. Network wide knowledge of all members, devices and VM’s. If I move a VM that configuration is already known by the network so all the connection information moves automatically. Reduces management complexity. All the switches are managed as a single entity. The cluster is masterless because every switch has a copy of the topology/configuration. Radically reduce managed elements. Drives costs down.

Dynamic Insertion - No longer have to decide where to place devices. Now can reconfigure the network with software. You connect the device and then steer the services to the device. Incorporation of partner services. Encryption as an example. Traffic that needs to be encrypted is just “dragged” to it.

Building the Virtual data center

What can you do with VCS Technology - Vertical integration just is not needed. Pick the Hypervisor, server and storage of your choice. VCS capable switches are designed to handle all types of storage and network traffic. The customer picks the devices they want to use. You can also use any combination of these as well.


Data Center # 1 - VCS Cluster with 64 port switch, FCoE 8000, Dell server with 10GB CNA’s, VMWARE, DELL EqualLogic for Storage. Data Center # 2 - Similar infrastructure with EMC Storage attached and IBM Servers. Going to migrate a VM between two data centers. They have a video playing on the server. Wizard walks him through. Movie plays with no interruption. Migrated a VM between data centers, maintain storage connectivity all over a single wire over a WAN link, looked pretty simple!!!
