remote access, local access, file sharing, mobile devices, WAN performance, it can be daunting.
Today users want to be able to access their data and applications from anywhere, with any device. The concern is how to create a safe environment, sharing and accessing files from a desktop enables a virtual desktop, a virtual application or even a mobile device. When users work in an office, then the concern of WAN performance
Citrix provides Citrix Workspace Suite IT to help tackle all these problems The Citrix Workspace Suite consists of ..:
- XenDesktop -. may provide the only hybrid cloud-enabled platform that Windows applications and devices on any device
- XenApp -. the industry-leading solution for virtual application deployment
- XenMobile - provides mobile device and application management and enterprise-class productivity apps for users on any mobile device
- Share File -. provides a secure enterprise file sync and share services for mobility, collaboration and data security, while meeting the requirements of enterprise business. It is the only virtual desktop optimized industry solution
- NetScaler -. Application Delivery Controller to optimize, secure and control the delivery of enterprise and cloud services
- Cloudbridge -. Application Delivery and WAN speeds up performance of companies to branch office connectivity.
More about all of these factors can be found under www.citrix.com.
with a new use of Citrix Workspace getting started helping Suite, Citrix Solutions Lab has a starter guide created the "Citrix Workspace Suite Reference Architecture" means. The following chart provides an architectural view of the surroundings.
The original design was to support 00 and XenDesktop XenMobile users, with 500 of these users in a branch be IPSec tunnel in NetScaler and Application Acceleration with Cloudbridge. All of this was used in vShpere 6 and is documented in the reference architecture.
The use shows some unique features such as Citrix PVS (provisioning server) RAM cache capacity with disk overflow. For each VM on the carrier physical host a small write cache file is created, but RAM is reserved for caching. Any correspondence which would normally go to the write cache on the hard drive have been cached in RAM. This strongly the IOPs and space requirements reduced, and when properly configured, IOPs would reduce the write cache files as little as1 IOP in many cases. The second advantage of Citrix was to use SSL on the VDA ability of XenDesktop to secure data exchange.
Since we are in a lab, we are always more opportunities to test things, and we just happened an additional 32 servers lying around, so we decided from 00 users to expand to 5,000 users, to see what it would require. To this we achieve:
- vShpere Used 6 to the servers
- Provisioned additional Hosted shared desktop VMs to physical servers
- Created the necessary delivery groups with XenDesktop
- Ran a 5,000 user test
We changed or added anything to the infrastructure. The delivery controller / broker, PVS servers, stores and NetScalers had no problem keeping up with the additional 3,000 users (got some nice charts and graphs in the reference architecture). If we could had additional physical servers lying around, we supported almost 10,000 users without modifications to our first infrastructure design. Our initial calculation of 5,000 users thought was to express our existing environment to about 80% of the hardware capacity.
