Background:
Shanghai XX company is specialized in machinery automation integrated control equipment design, manufacture and installation of small manufacturing business services. Enterprise IT environments are divided into design and office environments, where design environment consists of workstation design, PDM server designed document encryption server, the office environment, including PC and OA office server.
(1) design environment mainly in the service design, design workstation using Autodesk solutions, including professional 3D design software Inventor Vault design data tracking and collaboration management software. To meet the configuration requirements to run Inventor of the high hardware, while the hardware configuration flexibility to adjust to the operational needs of the design and software upgrades meet the needs of different types of design, businesses have adopted lease workstation way. Vault encryption software and service software runs on Taiwan Dell r730 server.
(2) non-office environment to support the needs of designers, including office PC platform software and OA, OA software running on Taiwan Dellr430 server.
In addition, the company currently file backup and restore program using TS-421 NAS system, OA office design documents and files backed up over the network to the TS-421 encrypted.
Issues and Challenges:
After the IT environment on the line to run for one year, and the problem should be solved gradually exposed.
First, rent workstations in performance can not meet the gradually emerging designers to design increasingly complex computing needs, it has begun to affect the efficiency of designers. There are currently two types of corporate design, assembly design one for staff, responsible for core components and assembly equipment design work; two for process design, simple components responsible for the design and design proofs work. Inadequate performance workstation designers to use the assembly is especially the case, originally hoped to rent to buy hardware upgrades rapid expectations, also due to high rents new hardware is difficult to obtain adequate budgetary support.
Secondly, companies do not set up a dedicated IT operation and maintenance jobs, but operated by the personnel department outsourcing IT service management approach. 12 units rented design workstations, 35 Taiwan office PC, two Dell servers, a NAS system, office network, coupled with the daily operation and maintenance work on multiple software platforms, so overwhelmed by the personnel department. At the same time outsourcing personnel and peacekeeping operations also design documentation possible leakage of high risk points.
After a comprehensive analysis of various IT-building programs on the market comparison, companies decided to move the entire IT environment to the cloud platform, design workstations, office PC, back-end servers do P2V (physical machine to virtual machine) after the conversion to move to cloud platform to run on a virtual machine form, to the maximum extent of building reuse existing IT hardware.
Construction practice:
Yung edge technology, cost-effective cloud platform for building programs ultimately selected. Cloud platform design plan, only buy a new station Dell R740 server, and the original R730 server hardware configuration upgrade, keep the original R430 server (using reserved for expansion) and NAS systems, the use of existing office network, to build hardware infrastructure cloud platform.
（1）新增的1台R740服务器运行12个3D设计云桌面：4个高配置云桌面和8个中等配置云桌面，分别满足装配设计人员和工艺设计人员的工作需求。R740服务器上配备NVIDIA M60显卡来提供所有云桌面运行所需的GPU资源。M60配置有16G显存和2颗GPU芯片，每颗GPU芯片上采用独立的vGPU划分方案，其中一颗GPU芯片划分为4个vGPU分配给高配置云桌面组，另一颗划分为8个vGPU分配中等配置云桌面组。实际运行中这两种vGPU模式下的图形计算能力方面完全满足两款设计云桌面运行Inventor设计软件的性能要求。榕力云平台可根据后续设计工作需求的变活，灵活地调整GPU配置。
（2）升级硬件配置后的R730服务器运行35个办公云桌面、1个Vault软件虚机、1个加密服务软件虚机、1个文件服务虚机和1个OA软件虚机。
在R730升级硬件配置之前，将原来在R730服务器和R430服务器（运行有Vault软件、加密服务软件、OA软件）上的物理磁盘分区通过Disk2VHD工具转换成虚拟磁盘镜像文件并导出，从而实现物理服务器到虚拟服务器的转换，即P2V转换。R730服务器完成硬件配置升级后，加入由榕力RLCenter软件统一管理的云平台。在R730服务器上创建虚机，并导入之前P2V过程中生成的VHD虚拟磁盘文件，最终完成业务系统从物理服务器到云平台的迁移。Vault服务、加密服务、OA服务顺利地从物理服务器迁移到榕力云平台上。
（3）云平台搭建完成后，TS-421 NAS系统继续作为存储备份系统是用。榕力为企业定制的虚机磁盘镜像定时自动备份程序，连同NAS系统自带的文件目录备份程序，为企业IT环境提供了系统级和文件级的双重恢复机制。即使发生重大硬件设备故障，也可以保证企业IT环境的连续运行。
价值收益
（1）强大的图形计算引擎保证Inventor专业3D设计软件的运行效果
榕力云平台借助NVIDIA GRID GPU，在每位设计人员启动云桌面后自动分配独享的GPU内核单元和显存，为Inventor专业3D设计软件运行提供相当于专业图形工作站的强大GPU计算能力的支撑，带来极致流畅的3D设计桌面体验；在关闭云桌面后又自动回收GPU资源；并且根据设计运算需求灵活调整GPU资源分配模式，提升设计人员工作效率。
（2）实现IT环境统一、高效运维，降低运维成本
榕力RLCenter云平台配置中心以图形界面的方式实现对云桌面平台的统一管理，包括虚拟机管理、云平台服务器管理、用户管理等，让企业IT运维管理变得轻松高效。云平台能够灵活地应对持续扩展的IT需求；在此之前IT硬件的淘汰更新需要支付大额的成本支出，而租用模式也不够灵活；使用云平台之后，企业通过调整云桌面和虚拟服务器的虚拟资源配置，就能实现IT硬件资源的最大利用率，IT硬件支出真正做到按需购买。
（3）IT环境安全可靠
在云平台方案中，设计软件运行在云服务器上，仅有桌面图像传送到设计人员操作的云终端，设计文档始终驻留在云服务器上，从而保证设计文档的隔离保护；并可配置云终端U盘类设备的读写权限，避免企业设计文档资料泄露，提升系统安全性。此外，云平台上实现了虚拟VLAN划分，设计云桌面、Vault虚拟服务器及加密软件虚拟服务器，和办公云桌面、OA虚拟服务器，分属不同VLAN，实现更安全的网络隔离。
