Virtualization Introduction

Definition - Virtualization• Wikis - http://en.wikipedia.org/wiki/Virtualization
> Virtualization is a term referring to the abstraction of computing resources
• About.com http://cplus.about.com/od/glossar1/g/virtualization.htm> Virtualization is a technique for hiding the physical
characteristics of computing resources to simpllify the way in which other systems, applications, or end users interact with those resources.
> Virtualization lets a single physical resource (such as server, OS, application or storage device) appear as multiple logical resources; or making multiple physical resources (such as storage devices or servers) appear as a single logical resource.

The Need for Virtualization• Consolidation multiple hosts and services• Leads to …
> Increased hardware utilization(Mostly, avg util < 15% or 20%)
> Increased resource allocation flexibility> Reduced power requirements> Reduced management cost> Lower cost of ownership

Network Virtualization
13
Network Virtualization• Combining h/w network resource, s/w network
resources into a single administrative unit.• Goal
> Efficient, controlled, secure sharing of the networking resources
• End product – Virtual Network> External → VLAN> Internal → On a single host,
Network Resource Allocation. Building an Internal Virtual Network.
14
Crossbow Network Virtualization• Crossbow – Project Name in OpenSolaris for
Network Virtualization - http://www.opensolaris.org/os/project/crossbow/
• Carve up hardware NIC into multiple virtual NICs• NIC Virtualization functionality is provided by the
MAC layer and VNIC pseudo driver• MAC layer: core virtualization, rsource partitioning
and virtual switching, leveraging hardware classification
• VNIC driver: expose virtual NICs which appear to the system as regular NICs
15
Why it is important• Virtualized Environment
> Partitioned Applications> Partitioned Hosts> By itself, it is another Eco-System
● Required Virtualized Networking Infrastructure
• Challenge> One virtual host dominates the Physical NIC> Virtual Host to Virtual Host communication – Security
Concern > TCP/UDP packets from getting into NIC > etc...

Storage Virtualization
21
What is Storage Virtualization• Storage virtualization is the pooling of multiple physical
storage resources into what appears to be a single storage resource that is centrally managed.
• Storage virtualization automates tedious and extremely time-consuming storage administration tasks
• Hides the physical complexity• Technology
> RAID 0,1,5,6,...> Solaris 10 – Zetta File System (ZFS)> Open Storage & Unified Storage> ...
22
Storage Complexity
• Pool of disks• Tier of Storage
> SATA, SAS, FC, SSD, (RAM),...• Access Path & Standards
> NFS, FC, iSCSI, CIFS,...• Volumes• RAID Level• Replication• Snapshot / Cloning• etc...

24
What is ZFS?A new way to manage data
The world's first 128-bit file system
With check-summing and copy-on-write transactions
A pooled storage model –no volume manager
Especially architected for speed
End-to EndData Integrity
Huge Performance Gains

Solaris Containers • Workload isolation features
> Privileges> Zones
• Resource Management Tools> Guarantee minimum CPU use (FSS)> Limit maximum CPU use (pools, processor sets)> Limit physical memory use (resource capping daemon)> Limit virtual memory use (projects, capped-memory)> Limit network bandwidth use (ipqos, crossbow)
34
Resource Control• By default, all zones use all CPUs
> Also, tools like prstat base %'s on all CPUs

Desktop Virtualization
39
Desktop Virtualization• Server-Centric computing model – designed to host
and centrally manage desktop virtual machines in the data center while giving end users a full PC desktop experience
• Technologies> VNC> Citrix> Remote Desktop (RDP)> Terminal Server
• Virtual Desktop Infrastructure (VDI)
