What is Virtualization ?



Logical representation of resources not
constrained by physical limitations.

– Create virtual resources within single
physical device or combining multiple
devices.

– Reach beyond the box – see and
manage many virtual resources as one

– Dynamically change and adjust across
the infrastructure

A comprehensive platform to
help virtualize the infrastructure


Across the IT Industry , virtualization is used today as broad term :
Of that something refers to the abstraction of computer resources.

In Marketing Terms :
A Proven IT approach that pools and share resources to reduce costs , optimize
utilization and create an infrastructure in which supply can dynamically meet
demands.

In Technical Terms
Virtualization is decoupling of software from hardware . Hence , it is the abstracting of
the software from the underlying implementation.

In Original sense of the term
Virtualization is related to the creation of a virtual machine (VM) using a combination
of hardware and software.
A number of discrete identical execution environments ( VMs) deployed on a single
computer each running an operating system.


Virtualization Explained

Conventional Servers: Multiple Workloads, Multiple Servers

Low Utilization of Resources Low flexibility of resource allocation to workloads
Low Efficiency More to Manage
Add Costs Complicates Infrastructure

Virtualization Explained

Power Servers : Multiple Workloads, One Server!

Virtualization Concept

Virtual Resources
Proxies for real resources: same interfaces/functions, different attributes.
May be part of a physical resource or multiple physical resources.

Virtualization
Creates virtual resources and "maps" them to real resources.
Primarily accomplished with software and/or firmware.

Resources
Components with architected interfaces/functions.
May be centralized or distributed. Usually physical.
Examples: memory, disk drives, networks, servers.

Separates presentation of resources to users from actual resources
Aggregates pools of resources for allocation to users as virtual resources

• Hardware partitioning subdivides a server into fractions, each of which can run an OS
• Hypervisors use a thin layer of code to achieve fine-grained, dynamic resource sharing
• Type 1 hypervisors with high efficiency and availability will become dominant for servers
• Type 2 hypervisors will be mainly for clients where host OS integration is desirable

PowerVM delivers firmware-based security
Unlike x86-based products such as VMware, the PowerVM hypervisor
is secure by design. IBM is the only vendor that has designed the
virtualized environment from ‘bare metal’ through the hypervisor.

PowerVM hypervisor is part of the digitally-signed firmware with strong
cryptography which makes it impossible to remotely install a modified
fileset into the EPROMs of Power Systems.

There are zero vulnerabilities reported against PowerVM by US CERT
or by MITRE Corporation

PowerVM is certified at a CC Evaluated Assurance Level 4+

Remember, zero is a number too …
a very good number in the Security domain.

Positive Feedback: Analyst commentary on
PowerVM

“IBM’s clear leadership position in the
traditional Unix area — coupled with
its more advanced PowerVM
virtualization stack — will continue to
be the core reason to adopt IBM
technology. The PowerVM stack also
gives POWER7 advantages over
other hypervisor-based systems
alternatives and, most importantly, the
ability to equally support complex,
mixed-application workloads across
multiple operating systems.”
• Brad Day, Forrester Research
• (August 2010)

Approaches to Disk Virtualization


Why Disk Virtualization?
Disk virtualization complements server virtualization
– Both technologies help increase flexibility and speed responsiveness

Storage management used to be manually intensive, time-consuming
and disruptive to the business
Disk virtualization can help change that to automatic, time-saving and
non-disruptive to the business
Radically changes the way you think about and work with storage to
make it fundamentally more flexible than just storage boxes alone


In-Band Implementation
In Band (Symmetric)
–Software is in the data path
–All I/Os go through the software
Advantages
–Better management possibilities
–Apply functions across all managed storage
–Large caches can enhance performance
Disadvantages
–Some I/Os experience latency


Out of Band Implementation
Out of Band (Asymmetric)
–Control is outside the data path
–I/Os follow the data path
Control Advantages...
Path –Very little latency added to read/write activity
–Very scalable solution

Disadvantages...
–Some In-band intervention required, either at the host
Data or switch, such that all I/Os experience some amount of
latency
Path –Copy services are difficult to implement
–Performance is limited to speed of block device

Performance

SVC does not hamper performance
– Worst case, introduces minimal delay (50-60 microseconds or .05-.06
milliseconds)
– Some cases of improved performance, should plan on equivalent performance
• Increased cache, Increased Striping, etc.
Strenuously tested
– Independent SPC testing – approximately 70,000 IOPs per I/O Group (2145-
8G4s running V4.3 firmware)
http://www.storageperformance.org/results/#SPC1_Results
SVC is designed to scale linearly
– Two I/O groups offer 2X performance of one I/O group- up to four per cluster
– Can add additional clusters if needed
• Might do this for other technical reasons (some other maximum)
• Sometimes, business factors (“eggs in a single basket”, risk mitigation,
politics)
The choice to add performance without storage, or storage without performance
