Best practices
The fol owing best practices will help ensure a secure and stable environment:
• Keep the write filter enabled when you are not performing necessary configuration.
• Monitor and modify the RAMDisk as necessary (see Memory management for more information).
• When instal ing large applications, increase the size of the RAMDisk or temporarily change the environment variables TMP
and TEMP to point to C:\Temp (create the folder first, if needed). Be sure to change environmental variables back to
their default settings after instal ation.
Note
A more detailed procedure might be available in the Administrator Guide for your operating system (see For more
information).
Memory management
For the most part, the easiest RAM partition to manage is the UMA frame buffer. The size can range from 32 MB to 1 GB. The
target size depends on how much video is used in day-to-day operations. If the thin client is used to connect to a remote
session for general office work, then the video buffer can be lower since video operations will not be performed very often.
On the other hand, if there is a lot of video streaming in the remote session, the video memory might need to be increased
because often some of the rendering is left to the client device.
The same is the case with the RAMDisk. For more intense work, even in a remote session, the RAMDisk should be set to a
larger size because there would be more I/O request packets (IRPs). For general office work, a smal er size would fulfill the
need.
In all cases, it would be best to start with the default values and progressively adjust them as needed. Remember that
increasing or decreasing the size of these two partitions has a direct relation to main system memory, which could have an
impact on how many or even the type of programs that the system wil be able to run.
One of the best memory management techniques is simply to reboot the thin client. Doing this will clear out al memory
caches and gives the system a fresh start. As the memory fil s up, the system wil start to destabilize. When this happens,
random errors can appear, or the system might even just crash. If possible, HP recommends performing a daily reboot on al
thin clients. For environments where a daily reboot is not feasible, HP recommends performing reboots as often as possible.
There are also certain functions that could have a detrimental effect on the thin client, so these best practices should be
followed to minimize problems:
• Scheduled tasks—Often, in an enterprise environment, there are tasks set to maintain personal systems such as
desktops and notebooks. However, these same tasks can harm the flash drive on the thin client and should not be run.
One example is Disk Defragmenter. Not only would Disk Defragmenter have no real value on an SSD, it would write
directly to disk and shorten the life of the flash drive. Other reoccurring tasks, such as Windows Update and WinSat
should also be avoided so the flash drive is not subjected to excessive writes.
• Image builds
– When building an image, it is best to turn off the write filter and redirect the Temporary Internet Files and TEMP
directories to the C: drive. Often, the RAMDisk does not have enough free space for application installers, so it could
cause various issues during application instal ation. Building an image in this way avoids these problems and is as close
to building an image in full Windows as possible. Instal al necessary applications, make sure that al necessary
reboots are performed (some applications require more than one) and then redirect the Temporary Internet Files and
TEMP directories back to the RAMDisk. Then, turn on the write filter and test the system with the image.
– It is important to make sure that none of the applications instal ed require, or even attempt to configure, a page file, as
this is not supported.
– When building or cloning an image, do not take up al of the space on the flash drive. A smal amount of space should
be left for the EWF volume, which is created by the operating system. 10 MB of space wil al ow plenty of room for the
volume.
