Challenges With Desktop Computing

The “thick-client” PC has been the workhorse of desktop computing. It has offered the best available combination of price, performance, and capabilities. However, for many use cases thick-client PCs are less than an ideal solution. Among their drawbacks:•Difficult to manage•High total cost of ownership•Difficult to protect and secure data•Inefficient resource utilization

Securing the Infrastructure: A Simple Checklist

• Standard security infrastructure

• Harden the platform based on the respective technologies

• User Authentication and User Profiling

• Clear boundaries of management

• End Client Protection

• Access Control policies

• And finally ….Monitoring & Compliance

Cisco Datacenter Optimization for Desktop Virtualization

Simplified Management• Embedded single point of management and provisioning • Visibility and control across datacenter organizations• Infrastructure policy management and compliance

Scalability and Rapid Deployment

• Massive Scalability: Scales to 320 servers (Thousands of Virtual Desktops)

• Simple Operation: Start in Minutes, Scale in Seconds• (Cisco Service Profiles)

Built for Virtualization• Fine-grained control, portability, and visibility

of network, compute, and storage attributes• More than double the memory capacity of competing systems

(60% more virtual desktops per blade)

Unified Fabric Infrastructure• Wire once, low latency FC and Ethernet• Less than half the normal number of adapters, switches (LAN

and SAN), cables (1/3 less infrastructure cost)

Cisco UCS - Ideal Platform for Desktop

VirtualizationThe Cisco UCS is designed to dramatically reduce datacenter total cost of ownership while simultaneously

increasing IT agility and responsiveness.
