Primary Storage Setup for OVM | Citrix Systems 4.2 guide

Chapter 12. Installing Oracle VM (OVM) for CloudPlatform

4. Repeat for any additional hosts that will be part of the OVM cluster.

Note

After ISO installation, the installer reboots into the operating system. Due to a known issue in OVM Server, the reboot will place the VM in the Stopped state. In the CloudPlatform UI, detach the ISO from the VM (so that the VM will not boot from the ISO again), then click the Start button to restart the VM.

12.4. Primary Storage Setup for OVM

CloudPlatform natively supports NFS, iSCSI and local storage. Each iSCSI LUN can be assigned to exactly one OVM cluster as the cluster's primary storage device. Following is a summary of the steps that you need to do. For details, see Oracle documentation on preparing storage repositories at http:// download.oracle.com/docs/cd/E15458_01/doc.22/e15444/storage.htm#sthref65.

1.Map your iSCSI device to the OVM host's local device. The exact steps to use depend on your system's peculiarities.

2.On every host in the cluster, create the same softlink name so CloudPlatform can use a consistent path to refer to the iSCSI LUN from any host. For example, if the softlink name is /dev/ovm-iscsi0:

ln -s /dev/disk/by-path/<output of previous command> /dev/ovm-iscsi0

Make a note of your softlink name. You will need it later.

3.Exactly once on any ONE host in the OVM cluster, format the OCFS2 file system on the iSCSI device.

12.5. Set Up Host(s) for System VMs

Before proceeding to install the CloudPlatform Management Server, you need to install a non-OVM hypervisor on at least one host that will run the CloudPlatform System VMs (which are not supported by OVM).

1.Install the non-OVM hypervisor on at least one host by following one of the instructions below, depending on which hypervisor you want to use:

•Chapter 8, Installing XenServer for CloudPlatform

•Chapter 9, Installing KVM for CloudPlatform

•Chapter 10, Installing VMware for CloudPlatform

2.When you set up the pod that will contain the OVM cluster, remember to include this non-OVM host in its own cluster along with the OVM cluster in the same pod.

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.
