VSP DATA CENTER PRODUCT LINE 
The SIMtone VSP product line allows service providers, enterprise organizations and small- and medium-sized businesses to easily transform existing application and desktop infrastructures into “cloud computing-enabled” infrastructures, highly manageable and securely accessible on-demand and on-the-fly from any LAN, WAN or Internet access point.
The SIMtone VSP enables multiple and diverse operating systems and applications hosted in virtual environments, terminal servers and blade PCs, as well as on existing distributed desktop computers, to be aggregated, managed, migrated and provisioned as end-users' cloud services very simply.
The SIMtone VSP provides a simple, inexpensive yet flexible path towards virtualization, offering enterprises and small/medium businesses a smooth, continuous and failback-safe migration from distributed to virtual-desktop environments, flexibly and securely manageable in stealth, non-addressable IP environments, in-house or in external hosting facilities.
SIMtone-based desktop and application services provide a powerful, cost-effective and secure alternative to solutions such as Citrix, enabling businesses to consolidate, virtualize and cloud-enable their desktop and application infrastructures inexpensively, delivering to users full and secure access to their computing environment on demand from any LAN or Internet access point, without requiring a computer.
SIMtone VSP products are available in three versions: Business, Enterprise and Service Provider editions.
All VSP service products allow the management, migration aggregation and service profiling of existing physical and virtual desktop and application infrastructures into cloud services easily and securely accessible by end users from anywhere.
SIMtone VSP products include a GUI-based administration console to easily provision, activate and manage virtual guest machines, terminal servers, blade PC and distributed PC-based desktops on-the-fly. This provides an extremely simple transition to virtual-desktop environments, while leveraging existing investments in IT infrastructure to instantly cloud-enable desktop services.
VSP products support secure, stealth, private and multi-tenancy hosting, automated SIMtone USP access-services registration and activation and SIMtone USP XAS service-management features.
SIMtone VSP products support any combination of VMware Server and ESX, Windows XP, Vista and Terminal Server hosts.
VSP Enterprise offers multi-zone network security deployments.
VSP Service Provider Edition (VSP SPE) offers automated subscriber-based provisioning, user-activity-driven, peak-capacity-based guest-machine management, load balancing, and failure recovery, radically reducing virtual datacenters real-estate and power requirements.
