12 Windows Server 2012 Provides network fault tolerance andcontinuous availability Aggregates bandwidth from multiplenetwork adapters Windows Server 2012 R2 Introduces a new mode, Dynamic mode. Balances based on flowlets Optimized utilization of a team onexisting hardware Virtual adapters Team network adapter Operating system Dynamic NIC Teaming optimizes utilization of a team on existing hardware, thereby maximizing ROI

14 ACL s Windows Server 2012 Enabled traffic to be allowed/blockedbased on source and destination VM Windows Server 2012 R2 Allows or blocks traffic for specificworkloads Filter traffic based on: Network address Application port Protocol type S tateful packet inspection Parent Partition Extension C Extension D Extension A Virtual Switch Capture Extensions Filtering Extensions Forwarding Extension Physical NIC VMNIC Virtual Machine Extension Miniport Extension Protocol

15 Remote Live Monitoring provides remote packet and ETW event capture from any host in the datacenter, enabling low-touch diagnostics at high scale Server or client with Microsoft Message Analyzer Windows Server 2012 R2 WMI to configure the filters and truncation WMI starts/stops the session Truncated network traffic redirected ETW events Windows Server 2012 Remote monitoring of network traffic isnot simple Windows Server 2012 R2 Mirror and capture network traffic for remote and local viewing GUI experience with Message Analyzer Supports remote offline traffic captures Filtering based on IP addresses and VMs
