This is all about service levels:
• Non-disruptively move data between
servers, applications, storage
• Virtual application provides single

Virtualization Promise: IT Agility and AutomationOther Applications
• Data warehouse
• Requires Tier 2 or 3 storage
Critical Applications
• Financial data
• Requires Tier 1 storage

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 •
