Persistent and lengthy desktop virtualization is a hard road to struggle with.

Combined with http://www.aliyun.com/zixun/aggregation/14402.html in hospital clinical care "> Desktop virtualization What are the uses? In fact, by combining desktop virtualization technology, Doctors and nurses spend 45 minutes a day in logging in and out of the workstation.

Speed is not a strong point for desktop virtualization (people in it tend to spend time on management and funding). The hospital's vice President Hughes and Wes Wright CTO are planning to replace the existing Wyse company's 0 client desktop workstations and laptops, using Cisco's unified Computing system. and VDI Then adopt Citrix's XenDesktop and XenApp technology.

"When the ipad comes out, people are already used to it." The characteristic of the instantaneous connection exposes the defects of the existing system of the hospital. We had to convince hospital clinicians to spend 3-5 minutes a day on our new PC. At the doctor-Patient Safety Forum, it was agreed that such slow logons would affect the safety of patients. For us, Desktop virtualization does not reflect our return on investment, and ultimately cost savings and standardization should be based on "speed."

Initially, the average time to log on to the Desktop virtualization 0 client is 43-45 seconds. If you work with multiple workstations, you only need to log in one day. This will greatly reduce the logon time. In one months, 3000 users can reduce the number of logons 10,000 times when they work across workstations.

"Clinically, we need less than 15 seconds of connection time, not clinical we need less than 10 seconds of connection time," Wright said. This saves time and saves money. You can sum up, do not have to reload the program again, do not have to enter the username and password again, this will save how much time ah. From the user experience, 15 seconds of Time VDI is the best choice.

"Over 400 applications are now virtualized, and it architects are planning to move these applications into VDI within 4 years." "said Hughes. User acceptance requires a process in which all applications and data in the datacenter need to migrate from a fat client to a thin client.

In the datacenter, redundant code is everywhere. Data is running in a VDI environment, and you need to make sure that these applications are still available when there is a problem with the network.

In addition, the IT department needs structural adjustment. "The servers that have been working need to be reassigned. They need to work based on the user experience rather than on the server. Hughes explained.

However, the infrastructure itself has been optimized for many years, and applications that used to be on the desktop are now moving to the data center. "These depend on the scalability of the data center, rather than buying a workstation." Now we need to have a change of mind to control the data center by changing the model we can use. "said Hughes.

Scalability is a major factor in user purchase. "When the xendesktop is used in the existing blade system, the full load of the system may affect the user's use." "said Hughes. When using XenDesktop on Cisco's UCS, the full load of the system will not affect the user's use.

"Moving applications to XenApp requires XENDESKTOP environment support, which is a continuous and lengthy process that takes 1 years to slow down," Wright said. This is a major project, in the actual deployment phase, about six months still have 400 to 500 applications waiting to be virtualized. ”
