1
In View Administrator, click View Configuration > Servers.
2 In the View Servers panel, select a View Connection Server instance and click Edit.
3 Select security and optimization settings for data transfers and local desktop operations.
Optimizing Data Transfers Between Local-Desktop Host Computers and the
Datacenter
You can reduce the amount of data that is sent over the network during transfer operations between the client
computers that host local desktops and the datacenter. You use deduplication and compression to optimize
data transfers.
Table 13-3 shows the deduplication and compression settings for data transfers.
Transfer operations include checking in and checking out desktops, replicating data from local desktops to the
datacenter, and downloading system images to local desktops.
You can determine the impact of deduplication and compression on data transfers by reading the View Client
with Local Mode logs. See “Determining the Effects of Deduplication and Compression on Data Transfers,”
on page 234.
Table 13-3. Deduplication and Compression Settings for Data Transfers
Setting
Description
Use deduplication for Local Mode operations Prevents redundant data from being sent from client
computers to the datacenter. Deduplication operates on
transfers from the client computer to the datacenter,
including replications and desktop check-ins. Deduplication
does not take place when desktops are checked out.
With deduplication, the client computer detects identical
blocks of data and sends a reference to the original block
instead of sending the entire block again.
Deduplication is valuable on slow networks because it saves
network bandwidth. However, deduplication can add to the
CPU workload on the client computer when it checks for
identical data blocks and to the I/O workload on View
Transfer Server when it reads duplicate blocks from disk. On
fast networks, it might be more efficient to disable
deduplication.
The default is not to use deduplication.
Use compression for Local Mode operations Compresses system-image and desktop files before sending
them over the network.
Like deduplication, compression saves bandwidth and
speeds up transfers over slow networks. However, View
Transfer Server uses additional computing resources to
compress files. When you decide whether to use
compression, you must weigh the benefits in network
performance against the cost in server computing.
The default is not to use compression.
Setting Security Options for Local Desktop Operations
You can set the level of security of transfer operations by using SSL encryption and tunneled connections
between the client computers that host local desktops and the datacenter.
Table 13-4 shows the security settings for local desktop operations.
Not using SSL or tunneled connection increases data-transfer speed at the expense of secure data
communication.
