Let‘s make this clear:

This is NOT a VMware sales show!

Some alternatives:

• Paralells• KVM• XEN• Virtual PC (okay, maybe not)

• Windows Server 2008 (soon)

Look, PowerPoint 2007 can do reflections!

…what a save game is to your computer game.

ClonesNever again install an OS again, just copy it

Linked ClonesLike clones, but without the big disk space usage

Record/Replay• Record all instructions on a VM for some time• Replay as often as you want• Attach a debugger during a replay • Get tracing results during a replay • Go live at any time during a replay

It’s mind-bending!(and still Alpha Release Quality)

VMware Server

Key Differences to VMware Server• Faster, less overhead• Run more VM’s on a single host machine• Supports up to 64 GB of RAM per VM• Supports up to 4 CPU’s per VM• Virtual Switches• Has High Availability options • And lots more…

VI3 – Virtual Infrastructure

Virtual Center

SAN(Storage Area Network)

Is VI3 a Single Point of Failure?

Let‘s first look at some more features...

Virtual Networking• Each NIC of your ESX Server is a 56 Port Switch• Supports for VLAN ID’s• Supports for Multipathing• Supports for Bandwith Shaping

Note:

• Only use Gigabit Ethernet NIC’s• Buy Servers with fast expansion slots • Buy your servers with lots of NICS • Use 2 or 4 GbE port NICS to save space

• One NIC port is used for the console• One NIC port is used SAN access (iSCSI/fibre)

High Availabilty (HA)

Consolidated Backup / ESX Ranger

Virtual Center

SAN

Is VI3 a Single Point of Failure?

• Make sure your SAN is fail-safe

• Use at least two ESX Nodes• Consider using Network Multipathing

• Use VMware HA• Use VMware VMotion• Use VMware DRS• Use Consolidated Backup

It might, but it can be avoided:

Let’s save some Energy…

20 Virtual Servers at local.ch• Use less power• Use less space• Produce less heat• Use less cables and switches• Spend less time in the server room

VI3 Setup Traditional

Think dense:• A FAST SAN of your choice• A Blade Center of your choice• 1 x cheap blade for Virtual Center• 9 blades /w 2 x QuadCore + 16 GB Memory

• Run LOTS of virtual servers • Almost no cables• Uses only 10 Rack Units• HA and DRS at it’s best

• High initial investment, but low running costs

(equals a cluster with 72 CPU cores and 144 GB Memory)

Bottom-line:

Virtualization can save you time/money/resources/hassle

Thanks!
