The Virtual Monitoring Challenge

Enterprises have been utilizing Tap solutions for network trac access for

many years. Trac capture, analysis, replay, and logging are now part of

every well-managed network environment. In recent years, the signicant

shift to virtualization—with penetration exceeding 50%—is yielding great

benets in eciency. However, today’s virtualization-based deployments

create challenges for network security, compliance, and performance

monitoring. This is because Inter-VM trac is optimized to speed up

connections and minimize network utilization. This imposes invisibility on

physical tools unable to extend easily into the new environments. Costly

new virtualization-specic tools plus training can aect the economic

benets and cost-savings of virtualizing. Currently, many tools suer from

limited throughput, hypervisor incompatibility, and excessive resource

utilization.

Next generation data centers use virtualization technology to deploy

private/public cloud environments on a single physical server, or across a

clustered group of servers. Traditional Taps cannot see the trac between

the VMs that reside on the same hypervisor (east to west trac), nor can

they “follow” VMs as they get migrated from one host to another.

At a Glance

• 100 percent visibility of trac between Virtual

Machines (VMs) and inter-blade visibility

• Installs in hypervisor kernel for full trac

visibility

• Enables visibility and control of network

trac in all best-of-breed hypervisors in

the virtual environment: VMware vSphere

ESX/ESXi Server 4.X/5.X; Citrix XenServer 5.6.x;

Redhat KVM 2.6.32; Oracle VM 3.0; Microsoft

Hyper-V 2012

• Generates Layer 2 and 3 statistics (packet

count, utilization, etc.)

Visibility is further reduced by the complexity of blade servers: with each

blade running multiple VMs on a hypervisor. Trac running on blades

servers share a common backplane, presenting a network blind spot, as

the physical network and its attached tools unable to see trac from the

internal network packets.

The Phantom Virtualization Tap Solution

The Phantom suite of software products provides 100% visibility of virtual

network trac, including the unseen inter-VM trac on hypervisor stacks.

This milestone solution has now expanded to support the industry’s leading

hypervisors. The Phantom Monitor is vSwitch agnostic supporting the

virtual standard switch, virtual distributed switch and next generation SDN

since it installs at the kernel level ( mirroring the network packets before

it arrives at the vSwitch). It is a software implementation of a switching

mechanism that manages communications between virtual network

devices and works identically to the physical switch. The Phantom Monitor

can mirror all trac within the virtual switch, apply smart TapFlow™ ltering,

and send trac of interest to any monitoring tools of choice. It can even

pass the mirrored trac to a physical port so physical tools can monitor

the data. Virtual trac is bridged to the physical world in an encapsulated

tunnel that can be terminated by a Net Optics xFilter™, Phantom HD™

and send trac to Director™ Data Monitoring Switch, or at any capable

termination point of your choosing.

Monitoring for Virtualized Computing

• TapFlow™ multi-layer L2-4 ltering engine

• Extends monitoring and access into the

Inter-VM networking layer

• Applies existing physical monitoring

tools, processes, and procedures to the

virtual network

• No interference with the data stream or VMs

• No modications needed in VMs

• Mirrors Inter-VM trac to virtual and physical

monitoring tools of choice

• Sends mirrored trac out physical NICs

in encapsulated tunnels

• xFilter™, Phantom HD™ terminates encapsulated

tunnels and sends trac to Net Optics Director

or to any of your existing monitoring tools

• One Phantom Virtualization Tap monitors trac

between VMs (one monitor instance is required

to be installed on each physical server)

• Scalable to support and administer high-density

environments

• Centralized Management for Phantom

Virtualization Taps VM (included software

component) manages multiple Phantom

Virtualization Taps and network trac

The Net Optics Phantom Virtualization Tap™ is a network trac monitoring and access solution for virtualized computing environments

developed for converged data centers. It captures data passing between virtual machines (VMs) and sends trac of interest to virtual and

physical monitoring tools of choice. This innovative software Tap supports all major hypervisors, including VMware vSphere ESXi 4.x/5.x,

Microsoft Hyper-V 2012, Redhat KVM, and Parallels. Unprecedented visibility of packet-level data lets you manage virtual network security,

compliance, and performance using your choice of instrumentation layer tools—physical or virtual; local or remote. Because the Phantom

Virtualization Tap can bridge virtual-to-physical in converged environments, you can maintain current policies while continuing to use

your existing physical monitoring tools.
