5.Repeat step 4 on every host.

6.On the storage server, run this command to get a unique ID for the new SR.

#uuidgen

The output should look like this, although the specific ID will be different:

e6849e96-86c3-4f2c-8fcc-350cc711be3d

7. Create the FiberChannel SR. In name-label, use the unique ID you just generated.

# xe sr-create type=lvmohba shared=true

device-config:SCSIid=360a98000503365344e6f6177615a516b

name-label="e6849e96-86c3-4f2c-8fcc-350cc711be3d"

This command returns a unique ID for the SR, like the following example (your ID will be different):

7a143820-e893-6c6a-236e-472da6ee66bf

8.To create a human-readable description for the SR, use the following command. In uuid, use the SR ID returned by the previous command. In name-description, set whatever friendly text you prefer.

#xe sr-param-set uuid=7a143820-e893-6c6a-236e-472da6ee66bf name-description="Fiber Channel storage repository"

Make note of the values you will need when you add this storage to CloudPlatform later (see Section 7.7, “Adding Primary Storage”). In the Add Primary Storage dialog, in Protocol, you will choose PreSetup. In SR Name-Label, you will enter the name-label you set earlier (in this example, e6849e96-86c3-4f2c-8fcc-350cc711be3d).

9.(Optional) If you want to enable multipath I/O on a FiberChannel SAN, refer to the documentation provided by the SAN vendor.

8.9. iSCSI Multipath Setup for XenServer (Optional)

When setting up the storage repository on a Citrix XenServer, you can enable multipath I/O, which uses redundant physical components to provide greater reliability in the connection between the server and the SAN. To enable multipathing, use a SAN solution that is supported for Citrix servers and follow the procedures in Citrix documentation. The following links provide a starting point:

•http://support.citrix.com/article/CTX118791

•http://support.citrix.com/article/CTX125403

You can also ask your SAN vendor for advice about setting up your Citrix repository for multipathing.

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.
