Providing you with a secure ubiquitous office

NEC offers a Virtual PC Type thin client system called the Virtual PC Center (VPCC). As a result of centralizing assets, the client is extremely simple, serving as a user interface without resident data or applications. A new thin client system solution integrates and centralizes client assets, such as data and applications, entirely on servers in the data center in order to fulfill three requirements:

• Enhancing security in the client environment

• Reducing TCO

• Providing mobility and working efficiency

This product is designed to realize the next step in the future platform environment. In this model, operating systems and applications on multiple PCs used by end users are virtualized and then run concurrently on a single server. From the localized thin client terminals, end users can access their virtual PCs on a server using screen, keyboard and mouse. All of the data and applications are stored on the server, and there is no data on the client terminals.

Optimal Resource Allocation

One server can be shared by multiple virtual PCs, and it is also possible to optimally allocate server resources such as CPU and memory across multiple PCs. For example, when a user executes a high-load task, resources not being used in other PCs on the same server can be redirected automatically to this PC.

Moving a virtual PC from one server to another is a very effective function not only at the time of high resource needs, but also when failures are detected or during maintenance operation. Creating a new virtual PC is also a simple operation that can be done in about 10 minutes using a template from the management console in the server.

These are some of the unique benefits provided by VPCC using virtualization technology.

Preferential server resource distribution to high-load virtual PCs.

Resources can freely be distributed to each virtual PC in a server. When a virtual PC's load becomes high, unused CPU/memory in the server are preferentially distributed to a high-load virtual PC.

Automatic virtual PC transfer to low-load servers.

System detects high-load status if the status continue for a given length of time. A virtual PC is transferred to a low-load server to adjust load balance. The virtual PC transfer is performed at short times without stopping business.

Easy to add virtual PCs

Virtual PC addition is available at short times by GUI operation in the management screen.

TCO Reduction

TCO reduction, one of the benefits of using thin clients, is further improved by utilizing unique functions developed by NEC. Compared with the traditional desktop model virtual thin client system, our system has achieved further operation management cost reduction by two means.

1. By using Sigma System Center (SSC), NEC's unique central management software, the operation of physical servers and virtual PCs can be centrally managed. By monitoring each virtual PC, distributing software, the environment settings and management of sessions between thin client terminals and virtual PCs.

2. By providing a server with pre-installed virtual PC server platform, as well as Windows® operating system for virtual PCs, initial workload and cost during the implementation is also reduced greatly.

As a result, compared with TCO of owning traditional business PCs for three years, this system's cost is 40% lower.

Smooth Streaming Video

Smooth-streaming video, which was not possible on earlier thin client systems, is now possible. A newly developed system LSI adopted for the thin client terminal US100 processes video image commands on a server, so the video image performance is comparable to traditional business PCs.

As a result, increasing use of video content as well as video conferencing is now possible in the thin client environment.

Voice over IP Telephony

Responding to the rapid expansion of Voice over IP Telephony (VoIP), NEC separated the soft phone on a server from voice processing on terminals using the new LSI on the thin client terminal US100.

VoIP with a voice quality as high as desktop phone systems is now possible in a thin client environment.

By enhancing these multimedia functions, the system realizes for the first time a performance that is a match for traditional PCs.

Ubiquitous Work Environment

In a virtual desktop environment, a ubiquitous work environment is achieved.

End users can retrieve their own desktop environment, regardless of which thin client terminal they are using. By using NEC's US100, users can also use their personal phone numbers from any terminal. The system can provide a ubiquitous work environment where our own desktop and our own phone lines are accessible anywhere.

Many benefits can be drawn from there, including productivity improvement by enhancing individuals' mobility.

Ecology

Compared to a distributed use of traditional business PCs, this new system can cut energy consumption by about 60% using the thin client terminal US100, and servers in the data center.

As stated thus far, NEC Virtual PC Center is able to expand the conventional notions of thin client capabilities. The system delivers the same performance level as traditional PCs, while significantly reducing TCO and providing robust security measures.
