Server bus requirement:PCI-Express

Problems which Xsigo Addresses

App DBWeb SAN

• Server’s use limited by connectivity• Time consuming to re-purpose– Re-configuration of cards, cables, networks

Challenge : Constrained Datacenter

Cannot respond quickly to changing needs.

Web Tier App Tier DB Tier

Challenge : Agility

• Time– Moves adds and changes

take weeks.

• Expense– Multiple teams involved in

each change.

• Risk– Re-cabling introduces risk of

mechanical failure and human error.

High costs. Response time challenge.

More Agility

100X faster management.

Why I/O Drives Cost

• Network complexity– Interdependencies abound

• Example:– Application migration– Caused by:

– Server upgrade– Maintenance– Recover under-used asset

Core Mgmt

• Consolidate I/O. Storage and networking share one cable.

• All servers can be configured with access to any network.

Faster and less costly to deploy VMware across hundreds of servers.

Save space with 1U servers, rather than 4U.

How It Works

• Create virtual connectivity

• Create I/O profile template

• Migrate connectivity

• Retains full identity of I/O

“Web Server”

How Xsigo Virtualizes I/O

• Xsigo fabric extends I/O bus– Extends I/O bus from servers to

the Xsigo I/O Director

– Apart from that, the network remains the same

• Self-contained– Fabric is fully self-contained

– Management tools built in to the Xsigo system

Routers

LAN SANDirectors

Self contained fabric

Routers & Switches

• Simplifies edge infrastructure– Extends I/O bus to the I/O

Director

– Consolidates edge networking

– Not replacing Ethernet as network fabric

– No change to core switch, VLAN, firewall, or SAN

• Simple, consistent I/O management– Single point of management

for configuration settings

Saves capital cost 4 ways:

1.70% fewer I/O cards and cables

2.Enables more use of 1U high servers

3.No edge switches

4.More I/O on blades at less cost

33% to 50% capital cost savings.

The Xsigo Difference

Relevance to VMware

Why I/O Matters for Virtualization

• 75% of users have five or more Ethernet ports per server.

• 85% of users have two or more SAN ports per server.

• 58% have had to add connectivity to a server specifically for VMs.

• 65% consider cable reduction a priority.

7 or more I/O ports per server!

Virtualization drives significantly more I/O.

Virtualization drives I/O demand for users:

vsw1 vsw2 vsw3

LAN SAN

Consolidate infrastructure, reduce costs.

Xsigo Benefits

Integrated separate network for VMotion

Virtual I/O

Isolate traffic to each VM or any logical grouping. No need for “open zoning.”

Scale I/O as needs change.

Guarantee bandwidth to specific VMs.Ensure application performance.

Predictable Application Performance

• Problem:

– Ensure performance of critical applications.

• Xsigo Solution

– Integrated QoS

1. Provision critical applications with dedicated I/O.

2. Set QoS by virtual machine.

3. QoS remains with VM even through VMotion.

Scalable I/O

TestSAN

BackupDMZ

VMotionDev

• VMware recommends dedicated I/O for:

‒ VMs running critical applications

‒ VMotion

‒ Management

• Xsigo I/O scales to meet changing requirements

Test SAN

VMotion Dev

Core Mgmt

Add I/O resources whenever needed.

Dedicated I/O resources:• Many cables.•Hours or days to modify.

Same I/O resources:• Two cables.• Change in minutes.

• Problem:– Large 4U servers required

to accommodate I/O cards.

– More power, space, cost.

• Xsigo Solution– Use virtual NICs and

– Get the connectivity you need in a 1U high server.

Fast & Secure VMotion

1) VMotion traffic

3) Traffic does not hit LAN

2) Travels over 10Gb link

• Problem

– VMotion traffic contains all data for VMs being moved.

– Security risk of moving unencrypted VMotion data over open network.

– Requires network bandwidth for rapid execution.

• Xsigo Solution

– Use Xsigo high-speed fabric to handle VMotion traffic.

– Traffic does not hit LAN.

– Fast 10 or 20Gb link.

Xsigo Integration with Virtual Center

Examples from W&W Testing

Tested

• Redundant configuration with 2 ESX server 3.5u1– (2 ports/server , 2 Xsigo chassis, 2 LAN switch, 2 paths to SAN)

• Binding / unbinding of profiles to ESX servers– with several vNICs and vHBAs each– without reboot

• Combination Xsigo vnics with vSwitches– ESX without vmnic0– added VLANs

• ESX multipath with vHBAs• QoS limitations with vNICs and with ACLs• Seamless failover, even during VMotion

– Cable pulls on LAN, SAN and chassis power

Summary

• Traditional connectivity limits virtualization deployments

• Xsigo addresses this with virtual I/O• Benefits:

– Predictable performance for critical applications– Scalable I/O resources– Agile management of I/O resources – Match I/O to the unique requirements of virtualization

• Well integrated with ESX 3.5

• Xsigo: Faster, Simpler,More Cost-effective Server I/O
