5 VIRTUAL CLUSTER SWITCHING (VCS) Scale-out, multi-path, highly resilient layer 2 Ethernet Fabric Self-forming and masterless through Distributed Intelligence Manage fabric as a single Logical Chassis
6 VCS Cluster Logical Chassis FCoE storage (Single Hop) iSCSI DCB FCoE storage (Multi hop) FC storage * CB500 Server Blade VDX 6746 Embedded Switch Creation of a VCS fabric between 2 embedded switches is free VDX 6720 Top of Rack Switch NAS vLAG VCS license allows creation of a Ethernet Fabric that scales past two switches FCoE license enables single and multi hop FCoE VCS AND FCOE * Future use case
7 VIRTUAL MACHINE MOBILITY CHALLENGES TODAY Limited sphere of mobility STP limits flexibility to a minimized, defined tree of switches L3 limits mobility to a single rack VM migration can break network/application access Port setting information must be identical at destination Map services (VLANs, QoS, security, etc.) to all physical ports Eases mobility, but undermines network and security best practices Distributed Virtual Switch Addresses configuration needs Consumes server resources and still restricted by physical limits Limited insight into where VMs are running VMs exist anywhere in the cluster L2 STP L3 to Agg. Layer !!!! Distributed vSwitch ? ? ? ?
8 MAC ID VDX 6746 VM MOBILITY WITH VDX 6746 & VCS AUTOMATIC MIGRATION OF PORT PROFILES (AMPP) Distributed intelligence of VM location throughout VCS fabric Granular VLAN, ACL, and QoS policies assigned per VM Zero network re- configuration required when a VM is moved across the VCS fabric
