Typical Lab Infrastructure is an IT Headache

Server sprawl – under desks, in closets

Aging, cast-off hardware

Dirty systems – inability to maintain “clean state”

Users and IT bogged down in provisioning requests

What is VMware Lab Manager?

Shared virtual machine libraryStores “multi-machine” configurations-- in state-- as a unit Creates copies of VMs using a fraction of storage normally requiredRuns identical copies simultaneously on the lab networkLeverages central pool of virtualization resources

A portal to access the libraryEasy to use web based interface, even for a non-IT professionalQuotas and Leases to control usage of resourcesCommunicate copies of running machines with a URL (LiveLink)

The premiere solution for managing “transiently configured” IT infrastructureSoftware development and testPatch testing, compatibility testing, onboarding new employeesTechnical support, demos, training

ROI – From Our Customers

Cost Savings

Consolidation reduces the number of physical machines required

Library/ Workspace allows physical machines to be freed for reuse (!)

Linked Clones provide tremendous storage cost savings

Time Savings

IT spends less time provisioning machines–you can allow users to do it themselves if you wish

Create fully-loaded machines in seconds instead of days

Set-up machines are stored in-state–no time wasted waiting for machines to boot or setting up tests

Everything can be automated

“VMware Lab Manager obsoletes many manual processes and lets us be more pro-active and innovative.I can't think of any other product, process or project that has had a greater impact in our daily activities. Everything just runs with little interference. Lab Manager will be key to the future success of software development in Avaya.”

Network Fencing

Property 1: Isolation between fencesVMs in fence A cannot directly communicate with VMs in fence B (including NETBIOS broadcasts)

Property 2: Zero modification of VMsVMs resume from check pointed state directlyNothing is modified inside the VMs, e.g. MAC address, IP address, security IDs, or machine name

Property 3: Internal resources accessibleVM inside a fence are able to access other resources on the same internal network

Property 4: External resources accessibleVMs inside a fence are able to access resources on the external network

Property 5: Internal machine externally accessible

An external IP address is assigned to the VM to be accessible from the external network, i.e., via RDP

Feature Benefits

Linked ClonesSpeed. Copy a VM in seconds.Space. Copy the disk of a VM in 16 MB (initially).Consistency. Exact copies

Saved StateStartup Time. Never wait for a VM to boot.Setup Time and Expertise. Only set up a test once.Bug Capture. Record bug situations

Fencing Concurrency. Allow multiple users to use benefits of Linked Clones and Saved State simultaneously.

Linked Clones, Saved State, and Fencing

VMware Lab Manager manages all the files, setup, maintenance,

and security associated with using these technologies.

Multiple Networks: Multiple NICs/Networks

LM3 adds to those networking capabilities
