Resizing Volumes

1.Log in to the CloudPlatform UI as a user or admin.

2.In the left navigation bar, click Instances, and click the VM name.

3.(KVM only) Stop the VM.

4.

 

Click the Migrate button

and choose the destination from the dropdown list.

Note

If the VM's storage has to be migrated along with the VM, this will be noted in the host list. CloudPlatform will take care of the storage migration for you.

5.Watch for the volume status to change to Migrating, then back to Running (or Stopped, in the case of KVM). This can take some time.

6.(KVM only) Restart the VM.

14.4.6. Resizing Volumes

CloudPlatform provides the ability to resize data disks; CloudPlatform controls volume size by using disk offerings. This provides CloudPlatform administrators with the flexibility to choose how much space they want to make available to the end users. Volumes within the disk offerings with the same storage tag can be resized. For example, if you only want to offer 10, 50, and 100 GB offerings, the allowed resize should stay within those limits. That implies if you define a 10 GB, a 50 GB and a 100 GB disk offerings, a user can upgrade from 10 GB to 50 GB, or 50 GB to 100 GB. If you create a custom-sized disk offering, then you have the option to resize the volume by specifying a new, larger size.

Additionally, using the resizeVolume API, a data volume can be moved from a static disk offering to a custom disk offering with the size specified. This functionality allows those who might be billing by certain volume sizes or disk offerings to stick to that model, while providing the flexibility to migrate to whatever custom size necessary.

This feature is supported on KVM, XenServer, and VMware hosts. However, shrinking volumes is not supported on VMware hosts.

Before you try to resize a volume, consider the following:

•The VMs associated with the volume are stopped.

•The data disks associated with the volume are removed.

•When a volume is shrunk, the disk associated with it is simply truncated, and doing so would put its content at risk of data loss. Therefore, resize any partitions or file systems before you shrink a data disk so that all the data is moved off from that disk.

To resize a volume:

1.Log in to the CloudPlatform UI as a user or admin.

2.In the left navigation bar, click Storage.

3.In Select View, choose Volumes.

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.
