  • 未來的架構會變成這個樣子 = Cisco Nexus + UCS LAN SAN A SAN B Ethernet FC Nexus 5K & 7K Data Center Bridging and FCoE UCS Server 7
  • Nexus 1000V Switch 8
  • 伺服器虛擬化 – 網路管理上所產生的問題 Problems: VMotion • 無法從實體的網路連線看到虛擬機的 資料流. • 無法觀察到虛擬交換器內的網路流 量 , 因此每個虛擬機的資料流無從 查起. • 虛擬機跨越不同的伺服器進行遷移, 其Policy無法跟隨. VLAN 101 VN-Link: • 將網路的控制延伸至虛擬環境 • 管理上保有一致性 9
  • Cisco Nexus 1000V -提供虛擬化環境第三方的虛擬交換器 Server 1 Server 2  Nexus 1000V 提供更進階的虛 擬網路交換能力 VM VM VM VM VM VM VM VM #1 #2 #3 #4 #5 #6 #7 #8  Access Control List  L2 Security VMware vSwitch Nexus 1000V Nexus 1000V DVSNexus vSwitch VMware 1000V  Spam Traffic VMW ESX VMW ESX  更能對於Vmotion給予彈性化 和連接的助益 10
