Managing View Transfer Server - VMware View Manager 4.5 Admin Manual

Small Deployment with Minimal Capital Expenditure
You can reduce the number of ESX servers required for your deployment if you increase the number of virtual
machines on each server. An ESX 4.1 server can host up to 500 virtual machines if most are not powered on at
the same time.
Use the following recommendations to reduce the amount of bandwidth and I/O operations required by each
virtual machine and maximize the number of virtual machines on an ESX server.
Set a View policy so that end users must use their View desktops in local mode only. With this setting,
n
the virtual machines in the datacenter remain locked and powered off.
Set local mode policies so that end users cannot initiate desktop check-ins, rollbacks, or replication.
n
Do not set automatic replication intervals.
n
Configure View Connection Server settings so that deduplication and compression are not used for local
n
mode operations. These settings might be helpful only if replication of local desktop data occurs over a
slow network during a time when the end user might notice a performance reduction on their client
computer.
Configure View Connection Server settings so that SSL is not used for local mode operations or
n
provisioning.
Use View Composer to create linked-clone desktops, but do not use the recompose feature. Instead use
n
traditional software update mechanisms to deploy patches and updates directly to local desktops on end
users' computers.
If the performance of View Connection Server is affected by the number of local desktops, set the heartbeat
n
interval to be less frequent. The default is five minutes.

Managing View Transfer Server

View Transfer Server is the View component that supports data-transfer operations for local desktops.
Understanding View Transfer Server
View Transfer Server manages and streamlines data transfers between the datacenter and local desktops. View
Transfer Server is required to support desktops that run View Client with Local Mode.
View Transfer Server sends data between the remote and local desktops in several situations.
When a user checks in or checks out a desktop, View Manager authorizes and manages the operation.
n
View Transfer Server transfers the files between the datacenter and the local desktop.
View Transfer Server synchronizes local desktops with the corresponding desktops in the datacenter by
n
replicating user-generated changes to the datacenter.
Replications occur at intervals that you specify in local-mode policies. You can also initiate replications in
View Administrator. You can set a policy that lets users initiate replications from their local desktops.
View Transfer Server distributes common system data from the datacenter to local clients. View Transfer
n
Server downloads View Composer base images from the Transfer Server repository to local desktops.
If a local computer is corrupted or lost, the data that was replicated to the datacenter can be recovered.
n
An event such as a network outage or the removal of View Transfer Server from View Manager can interrupt
active data transfers. View Transfer Server resumes the paused transfers when the components are running
again.
