Virtualization solutions from PacSoft
A Glance at Virtualization
Everyone is thinking about and implementing virtualization of one sort or another within their IT environment. To PacSoft, virtualization is more than just a buzzword. We can help you to determine your virtualization needs and put together a road map that will take your system on a path to greater efficiency and utilization. Virtualization simply put means that people, applications and hardware can interact with the virtual devices as if they were a single resource in the environment.
If you’re thinking you really don’t know where to begin when it comes down to where to start, you’re not alone. There are a lot of IT people out there who want to implement some sort of virtualization in their environment, but just are’t sure how to go about it. Whether you’re thinking about storage virtualization or are looking at partitioning a server into smaller virtual servers, PacSoft can help you plan and implement a solution for your organization.
Virtualization is the highest impact trend changing infrastructure and operations through 2012. It will change
how you manage, how and what you buy, how you deploy, how you plan, and how you charge .

Desktop Virtualization
PacSoft’s desktop virtualization solutions can help your company reduce total cost of ownership (TCO), increase business agility and continuity, enable anywhere access, and improve security and compliance. For companies new to desktop virtualization, deploying desktop virtualization as a first step can provide immediate cost savings.
Desktop virtualization offers a broad portfolio of solutions that empower companies to choose the technologies that best address their unique business and IT challenges while preserving their existing IT investments. PacSoft delivers desktop virtualization offerings for a wide range of situations—from always connected workers to those requiring more flexibility such as mobile workers. For connected workers, PacSoft and its partners deliver a Virtual Desktop Infrastructure (VDI) solution that allows organizations to centrally manage desktops in the datacenter while providing a personalized desktop experience for end users.
There's been a lot of buzz among small and medium-sized businesses (SMB’s) about the benefits of desktop virtualization. And it's no surprise -- desktop virtualization is an outstanding technology option that makes it easy for your business’ IT infrastructure to grow as your business changes and expands. Scalability is an important factor in any IT investment, but desktop virtualization offers a variety of other benefits.
Desktop Virtualization Saves Time
The option to save time during your workday is something most people wouldn't pass up. For those who would benefit from some extra time, one appealing aspect of desktop virtualization is its ability to do just that — save you time. Compared to the hours it can take to set up a personal computer with the appropriate hardware, software and updates, deploying a virtual desktop can be done in a matter of minutes.
But saving time continues well after the initial desktop deployment. End users can access their desktop from any remote location, allowing business to continue even when employees are physically out of the office. Not only can desktop access increase, maintenance tasks are reduced because support techs can deploy upgrades, updates, hot fixes and patches to all virtual desktops simultaneously.
Desktop Virtualization Saves Money
Not only do virtual desktops save time — they also save money. For the small or medium-sized business interested in reining in IT costs, deploying a virtual environment will be far less costly than deploying a slew of networked PCs. Why? Because you can make use of less-expensive thin client machines rather than costly personal computers.
Desktop virtualization can also save crucial funds by reducing the time spent by IT staff on routine desktop maintenance. With desktop virtualization, the IT department can more easily manage day-to-day maintenance and support tasks, allotting those newly found hours to projects that are more directly tied to business profits.
Desktop Virtualization Offers Security
Desktop virtualization also offers outstanding data security. Because no data is stored on the end user's computer, sensitive data stays protected on the company server. This means that a laptop left in an airport or rendered useless by an accidental fall will be an inconvenience, but not a major security issue.
A virtual desktop environment also offers an additional level of protection against malware and viruses. Because end users have no local hard drives and only have access to the network via the virtual desktop, the chance of them knowingly or unknowingly passing along a virus, Trojan horse or other malware to the network is greatly reduced, if not eliminated.
Desktop Virtualization Makes Computing Convenient
Certainly, deploying a virtual desktop environment makes day-to-day management easier and more convenient for your IT staff, but they're not the only ones who can benefit. End users will benefit from the convenience of desktop virtualization as well.
Desktop virtualization provides businesses with the opportunity to give end users access to their desktops, no matter where they are. Whether your employee is sitting in his office or is sitting with his laptop in an airport in Italy, as long as he has Internet access and the proper login credentials, he'll be good to go. With the number of traveling and telecommuting employees continuing to rise, the convenience of logging in to a virtual desktop is undeniable.
Server Virtualization
Server virtualization is one piece of the overall virtualization trend in today's IT environment. Server virtualization can be used to eliminate server sprawl - essentially making more efficient use of server resources, improving server availability, assisting in disaster recovery, testing and development and centralizing server administration. Server virtualization also allows you to realize a cost savings associated with hardware, power consumption, cooling and physical space utilization.
A basic definition of server virtualization is the masking of server resources, including the number and identity of each physical server, processor and operating system, from server users. Use of a software application divides one physical server into multiple virtual environments. Currently there are three popular approaches to server virtualization.
3 Approaches to Server Virtualization
Virtual Machine Model (VMM) – A host/guest paradigm where each guest runs on a virtual imitation of the hardware layer. The individual guest operating system is able to run without modifications and can run a variety of operating systems because each guest has no knowledge that it is not operating on real hardware. VMware and Microsoft Hyper-V are examples of the virtual machine model.
Paravirtual Machine Model (PVM) – This model is also based on the host/guest paradigm with the difference being that the PVM model DOES alter the guest system's code. This modification is called porting and supports the virtual machine monitor so it can utilize privileged systems calls sparingly. Citrix Xen and UML both utilize this model.
Virtualization at the OS level – This is not a host/guest paradigm as in the virtual or paravirtual models. In the OS level model, the host runs a single OS kernel as its core and exports operating system functionality to each of the guests. Guests must use the same operating system as the host, although different distributions of the same system are allowed. This distributed architecture eliminates the systems calls between layers, reducing the CPU usage overhead. Each partition must remain strictly isolated from its neighbors in order that a failure or security breach in one partition doesn't affect any of the other partitions. Virtuozzo and Solaris Zones are examples of virtualization at the OS level.
So- Why use Server Virtualization?
- Saves money
- Saves resources
- Makes migration, backup and recovery easy and manageable.
