Virtualization


Virtualization started as a means of server consolidation, but IT needs are evolving as data centers are becoming service providers. An isolated hypervisor cannot provide the speed and time to market required to deploy a complete application stack. To realize the full benefits of virtualization, organizations must look beyond simple consolidation and choose application-driven virtualization solutions that are integrated with the applications and infrastructure.

Why Aspire Virtualization?

Aspire offers the industry's most complete and integrated virtualization, from desktop to the data center. Going far beyond simple consolidation, Aspire enables you to virtualize and manage your full hardware and software stack.

Benefits of Virtualization

Virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate. Additional benefits include:

  • Reduce capital and operating costs.
  • Minimize or eliminate downtime.
  • Increase IT productivity, efficiency, agility and responsiveness.
  • Provision applications and resources faster.
  • Enable business continuity and disaster recovery.
  • Simplify data center management.
  • Build a true Software-Defined Data Center

ACCELERATE

Accelerate virtualization of business critical applications by increasing visibility and control across application tiers, improving storage I/O performance and availability and unifying backup and recovery across physical and virtual domains ֠all while maintaining security and compliance you can trust.

BUILD

Build resilient and secure private cloud services on your existing infrastructure and take your virtualized data center to the next level of resource optimization.

SECURE

As your IT business delivery model transforms from a static physical deployment, to consolidated virtual workloads, to on-demand service delivery ֠Symantecӳ VMware-integrated virtualization security solutions can help you to achieve the high levels of security and trust you need.


HOW IT WORKS

Virtualization 101

IT organizations are challenged by the limitations of today’s x86 servers, which are designed to run just one operating system and application at a time. As a result, even small data centers have to deploy many servers, each operating at just 5 to 15 percent of capacity—highly inefficient by any standard.
Virtualization uses software to simulate the existence of hardware and create a virtual computer system. Doing this allows businesses to run more than one virtual system – and multiple operating systems and applications -- on a single server. This can provide economies of scale and greater efficiency.

The Virtual Machine

A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host”.

A thin layer of software called a hypervisor decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.

Key Properties of Virtual Machines

VMs have the following characteristics, which offer several benefits.

Partitioning

Run multiple operating systems on one physical machine
Divide system resources between virtual machines

Isolation

Run multiple operating systems on one physical machine
Divide system resources between virtual machines

Encapsulation

Save the entire state of a virtual machine to files
Move and copy virtual machines as easily as moving and copying files

Hardware Independence

Provision or migrate any virtual machine to any physical server

Server Consolidation

Using server virtualization, a company can maximize the use of its server resources and reduce the number of servers required. The result is server consolidation, which improves efficiency and cuts costs.

It’s Not Cloud Computing

Cloud computing is not the same thing as virtualization; rather, it’s something you can do using virtualization. Cloud computing describes the delivery of shared computing resources (software and/or data) on demand through the Internet. Whether or not you are in the cloud, you can start by virtualizing your servers and then move to cloud computing for even more agility and increased self-service.

Server Virtualization Products

Designed for efficiency and optimized for performance, Aspire's server virtualization products support x86 and SPARC architectures and a variety of workloads such as Linux, Windows and Aspire Solaris. In addition to solutions that are hypervisor-based, Aspire also offers virtualization built in to hardware and Aspire operating systems to deliver the most complete and optimized solution for your entire computing environment.


Most servers operate at less than 15 percent of capacity, leading to server sprawl and complexity. Server virtualization addresses these inefficiencies by allowing multiple operating systems to run on a single physical server as virtual machines, each with access to the underlying server's computing resources.

The next step is to aggregate a server cluster into a single consolidated resource – which improves overall efficiency and reduces cost. Server virtualization also enables faster workload deployment, increased application performance, and higher availability.

Data Center Virtualization Solutions

With users demanding access to applications and services 24/7, IT needs are evolving. Data center solutions need to support these stringent service levels while keeping the costs low. The integration of Aspire VM with Aspireӳ leading enterprise software and hardware solutions offers significant advantages to data centers that support the most demanding customers.

Desktop Virtualization Products

Aspire desktop virtualization provides secure, anywhere access to Aspire Applications and other enterprise software and enables virtualized operating systems on standard client devices. It can be used to securely access nearly any application over the network from standard PCs, Macs, and iPad.

It can also be used to run multiple operating systems on laptops and desktop PCs for development and testing. Deploying desktops as a managed service gives you the opportunity to respond quicker to changing needs and opportunities. You can reduce costs and increase service by quickly and easily delivering virtualized desktops and applications to branch offices, outsourced and offshore employees and mobile workers on iPad and Android tablets.

Network Virtualization

Organizations need an easy way to connect with their ecosystem of internal and external customers, business units, partners, and branches. Aspire's software-defined networking (SDN) solution enables distributed enterprises to deliver trusted connectivity services with less complexity, in significantly less time, and at greatly reduced cost.

Network virtualization is the complete reproduction of a physical network in software. Applications run on the virtual network exactly the same as if on a physical network. Network virtualization presents logical networking devices and services—logical ports, switches, routers, firewalls, load balancers, VPNs and more—to connected workloads. Virtual networks offer the same features and guarantees of a physical network with the operational benefits and hardware independence of virtualization.
