Chapter 14. Working With Storage

Select the volume name in the Volumes list, then click the Resize Volume button

5. In the Resize Volume pop-up, choose desired characteristics for the storage.

a.If you select Custom Disk, specify a custom size.

b.Click Shrink OK to confirm that you are reducing the size of a volume.

This parameter protects against inadvertent shrinking of a disk, which might lead to the risk of data loss. You must sign off that you know what you are doing.

6.Click OK.

14.4.7. Reset VM to New Root Disk on Reboot

You can specify that you want to discard the root disk and create a new one whenever a given VM is rebooted. This is useful for secure environments that need a fresh start on every boot and for desktops that should not retain state. The IP address of the VM will not change due to this operation.

To enable root disk reset on VM reboot:

When creating a new service offering, set the parameter Volatile VM to True. VMs created from this service offering will have their disks reset upon reboot.

14.4.8. Volume Deletion and Garbage Collection

The deletion of a volume does not delete the snapshots that have been created from the volume

When a VM is destroyed, data disk volumes that are attached to the VM are not deleted.

Volumes are permanently destroyed using a garbage collection process. The global configuration variables expunge.delay and expunge.interval determine when the physical deletion of volumes will occur.

•expunge.delay: determines how old the volume must be before it is destroyed, in seconds

•expunge.interval: determines how often to run the garbage collection check Administrators should adjust these values depending on site policies around data retention.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
