Virtualization Technology Wave

This is all about service levels:

• Non-disruptively move data between

servers, applications, storage

• Virtual application provides single

Virtualized Flexibility:

• Create pools of servers, storage,

network and applicationsNetwork

Virtualization Promise: IT Agility and AutomationOther Applications

• Data warehouse

• Requires Tier 2 or 3 storage

Critical Applications

• Financial data

• Requires Tier 1 storage

Email Applications

• Logs and archives

• Requires Tier 2 storage

Multi-vendor

Virtualization within network systems is similar to server virtualization:- virtual process and abstraction from hardware, pooling of hardware resources

- unified fabric and I/O, common standard: spare parts, expertise, performance

FCoE: Fibre Channel over Ethernet

FCoE integrates FC storage traffic over Ethernet

� FC traffic shares Ethernet links with other traffics

� Requires a lossless Ethernet fabric

� Servers - storage network over Ethernet

FCoE benefits are the same of any I/O consolidation solution

� Both FC block and Ethernet traffic co-exist on same cable

Fibre Channel

Traffic

Ethernet

� Both FC block and Ethernet traffic co-exist on same cable

� Fewer adapters needed, less spare parts, Ethernet standard based expertise

� Overall less power and more Throughput

Plus additional advantages of being FC

� Seamless integration with existing FC SANs, no need for additional “gateway” device

Ethernet: Priority Flow Control

Priority Flow Control (PFC; formerly Class Based Flow Control)

� PFC will be limited to Data Center BCN domain

� A new PAUSE function that can halt traffic according to priority tag while

allowing traffic at other priority levels to continue

� Creates lossless logical circuits and QOS

ESX Server: Network Port Virtualization

Each Virtual Machine has its own virtual I/O interfaces

Network: Virtual NIC with its own MAC address

� ESX Server contains an Ethernet switch implemented in software

� Actual hardware Ethernet port behaves like a switch port

� Network operates transparently

Storage: Virtual disk controller

� VMware maps OS volumes (LUNs) to� VMware maps OS volumes (LUNs) to

storage resources

� VMware ESX contains a volume manager

and a cluster file system (VMFS)

� Can use storage from many places

� SAN, iSCSI, internal storage

� NAS - Can store volume as a file

� Storage operates transparently

Examples: - physical server pool management- ability to add/remove servers in minutes

Physical Server Pools

DRS

• DRS optimizes the resource allocation through the use of resource pools within same cluster• Ability to add or remove server to or from a resource pool• To shift compute load and provide capacity from one ESX pool to another •
