Detaching and Moving Volumes

14.4.4. Detaching and Moving Volumes

Note

This procedure is different from moving volumes from one storage pool to another as described in Section 14.4.5, “VM Storage Migration”.

A volume can be detached from a guest VM and attached to another guest. Both CloudPlatform administrators and users can detach volumes from VMs and move them to other VMs.

If the two VMs are in different clusters, and the volume is large, it may take several minutes for the volume to be moved to the new VM.

If the destination VM is running in the OVM hypervisor, the VM must be stopped before a new volume can be attached to it.

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

2.In the left navigation bar, click Storage, and choose Volumes in Select View. Alternatively, if you know which VM the volume is attached to, you can click Instances, click the VM name, and click View Volumes.

3.

Click the name of the volume you want to detach, then click the Detach Disk button.

4. To move the volume to another VM, follow the steps in Section 14.4.3, “Attaching a Volume”.

14.4.5. VM Storage Migration

Supported in XenServer, KVM, and VMware.

Note

This procedure is different from moving disk volumes from one VM to another as described in Section 14.4.4, “Detaching and Moving Volumes”.

You can migrate a virtual machine’s root disk volume or any additional data disk volume from one storage pool to another in the same zone.

You can use the storage migration feature to achieve some commonly desired administration goals, such as balancing the load on storage pools and increasing the reliability of virtual machines by moving them away from any storage pool that is experiencing issues.

On XenServer and VMware, live migration of VM storage is enabled through CloudPlatform support for XenMotion and vMotion. Live storage migration allows VMs to be moved from one host to another, where the VMs are not located on storage shared between the two hosts. It provides the option to live migrate a VM’s disks along with the VM itself. It is possible to migrate a VM from one XenServer resource pool / VMware cluster to another, or to migrate a VM whose disks are on local storage, or even to migrate a VM’s disks from one storage repository to another, all while the VM is running.

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.
