今天学习了一篇很有意义的帖子，特别是它的结论对我特别有帮助。帖子的原文地址：Reference Architectures that Scale: Citrix XenDesktop on FlexPod with Microsoft Private Cloud
下面是硬件的测试架构，使用的服务器是UCS 14刀，NatApp存储，Hyper-V，加载XenDesktop 5.6
The reference implementation achieved impressive results in our test runs, especially in comparison to previous testing with earlier generation Cisco blades. As a matter of fact, the tested configuration reduced the rack space needed to support 2000 users, decreasing it from 30 Rack Units (RUs) to 12 RUs. This density can help to lower power use, which directly translates into energy savings.
The results specifically showed that the Cisco UCS B230 M2 half-width blade (featuring dual-socket, 10-core processors and 256GB of memory) can support medium workloads up to 145 users per blade. A single FlexPod VDI design containing two Cisco UCS chassis units with 14 such blades can support at least 2000 virtual desktop workloads while maintaining acceptable response times. The results clearly demonstrated linear scalability of desktop workloads for this reference architecture. Detailed metrics are given below.

Microsoft, Citrix, Cisco, and NetApp successfully validated XenDesktop streaming 2,000 concurrent Windows 7 desktops to virtual machines hosted with Hyper-V. The deployment was built on a 16-node FlexPod with Microsoft Private Cloud infrastructure that comprises the hardware requirements in the Microsoft Private Cloud Fast Track program. The hardware, in conjunction with Windows Server 2008 R2 Enterprise SP1, Hyper-V, System Center 2012, and Citrix XenDesktop 5.6:
> > > * Validated that a single instance of Virtual Machine Manager and a single instance of the XenDesktop delivery controller successfully hosted 2,000 VDI workloads. > > * Verified single-server scalability: 143 Windows 7 desktops with 512 MB of dynamic memory (expandable to 2 GB) running knowledge worker load on a single Cisco UCS B230 M2 Blade Server with 20 cores and 256 GB of random access memory (RAM). > > * Validated a fully virtualized environment where all VDI components (such as Active Directory Domain Services, Microsoft SQL Server, VMM, XenDesktop, and Provisioning Server) were run in virtual machines. > > * _**Observed an 80 percent storage savings in comparison to a similar VDI environment without NetApp storage efficiencies.**_ >
