The Envisage Advantage

With the speed of business today, your enterprise needs a higher level of scalability without compromising stability or cost and performance efficiency. Envisage provides just that through virtualization technologies that help you optimize your technology resources and costs and achieve unprecedented utilization rates.

Benefits of Virtualization Include:
- Hardware consolidation reduces capital expenditures and energy costs
- Standardization of operating systems reduces errors
- Rapid provisioning improves time-to-market
- Automation reduces staffing costs
- Physical servers are made more interchangeable
- Portability improves availability, recovery, and flexibility

Envisage Virtualization Advantages:
- Automated delivery of IT infrastructure for the rapid scaling of solutions
- Best-practice OS builds and patching
- Private-network connectivity, ideal for hypervisor management
- Network storage based on iSCSI SAN and Fibre Channel SAN for virtual machine storage to enable high-end virtualization features
- Virtual Private Racks to allow integrated network performance
- Use of enterprise virtualization technologies such a VMware ESX and Citrix XenServer

VMware ESX
Envisage provides VMware ESX managed by VMware vSphere 4, a next-generation virtualization hypervisor and management solution. ESX operates directly on top of a physical server’s bare metal hardware to enable multiple virtual machines (VMs) to be created and operated on the single physical machine. Each VM can run an independent operating system—Windows, Linux and others. ESX also provides integrated management tools to manage both physical and virtual machine resources.

VMware ESX provides unique advantages and benefits, such as:
- Broad OS Support—simultaneously running diverse Operating Systems (including 32-bit and 64-bit)
- Symmetric Multiprocessors (SMP) Support—emulating up to 8 processors per VM
- Live Virtual Machine Snapshot—improving overall backup and recovery
- DRS – automatically assigns VM’s to physical servers with the lowest load, balancing performance
- vStorage Motion—migration of running VMs data between storage devices and physical servers with zero downtime
- Fault Tolerance – using unique vLockstep technology we can assure 100% uptime even in the case of complete node and storage failure.

Citrix XenServer
Envisage offers Citrix XenServer, a powerful, open, and easy-to-use server virtualization solution. XenServer is powered by the popular Xen® hypervisor, which operates directly on top of a physical server’s bare metal hardware to enable multiple virtual machines (VMs) to be created and operated on the single physical machine. XenServer also provides an industry-leading, easy-to-use management console that can provision and manage any number of physical and virtual machines across a distributed data centre environment.

XenServer provides unique advantages and benefits, such as:
- Unique Management Architecture - eliminating single points of failure and providing detailed monitoring
- Industry-leading Low Overhead - offering near bare metal performance
- Plug and Play Storage Architecture - allowing control over advanced storage functions
- Dynamic Workload Management - workload streaming from the network to both physical servers and VMs
- High availability - allowing VMs on a failed host to automatically restart on another physical server
- XenMotion Live Migration - migrating VMs between physical servers with zero downtime
