Učenje iz svojih datacentara

Inspirirani ljudima. Networking u Win Serveru 2012

Virtual RSS (vRSS) Windows Server 2012 VMs restricted to 1 processor for network traffic processing Windows Server 2012 R2 vRSS maximizes resource utilization by spreading network traffic across multiple virtual processors Now possible to virtualize traditionally network intensive physical workloads Requires no hardware upgrade and works with any NICs that support VMQ

NIC Teaming Windows Server 2012 Provides network fault tolerance and continuous availability Aggregates bandwidth from multiple network adapters Hyper-v switch port mode, hasing mode Windows Server 2012 R2 Introduces a new mode, Dynamic mode. Balances based on flowlets Optimized utilization of a team on existing hardware

Extended ACLs Windows Server 2012 Enabled traffic to be allowed/blocked based on source and destination VM Windows Server 2012 R2 Allows or blocks traffic for specific workloads Filter traffic based on: Network address Application port Protocol type Stateful packet inspection

Remote Live Monitoring Windows Server 2012 Remote monitoring of network traffic is not 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

QoS / VM QoS - Relative minimum bandwidth (preporučeno) - Strict minimum bandwidth - Maximum bandwidth limits (za WAN linkove, radi i VM2VM)

Primjena novih funkcionalnosti

Inspirirani ljudima. SDN

Software Defined Network - SDN

SDN in Win 2012 R2

Postojeća mreža nefleksibilna

Network virtualizacija - Enkapsulacija korištenjem NVGRE protokola - Riješava problem migracije između datacentara, clouda, hostera - Zadržavanja IP adresne sheme

Kako radi Network virtualizacija

Hyper-V Extensible Switch Benefits Open platform to fuel plug-ins Free core services Reliability and quality Unified management Easier to support

Hyper-V vSwitch i Network virtualizacija Introduces new hybrid forwarding HNV forwards HNV traffic Forwarding Extension forwards non-HNV traffic Richer switch extensions Extensions can view CA and PA packets Enables 3 rd party network virtualization Forwarding extensions can modify packet headers on both ingress and egress

Standardizirano upravljanje mrežom Standards-based CIM model Switches running Open Management Infrastructure (OMI) Switch Management PowerShell Cmdlets Problems solved Common management interface across multiple network vendors A utomate common network management tasks

VPN Gateways

SDN Partneri Hyper-V Switch extensions NVGRE-aware hardware Switching ASICs Task offload enabled NICs HNV gateways Hardware, Appliances and Software Gateways OMI managed switches

IP address management - IPAM Inbox feature for integrated management of IP addresses, domain names, and device identities Tightly integrates with Microsoft DNS and DHCP servers Provides custom IP address space display, reporting, and management Audits server configuration changes and tracks IP address use

IPAM u R2 Windows Server 2012 R2 Manages virtual address space in addition to physical address space Imports and exports network configurations automatically through plugin for System Center Virtual Machine Manager Enables synchronization of Active Directory Sites and subnets information with IPAM
