Overview Citrix® XenServer™ Dell™ Edition with its 64-bit open-source Xen hypervisor at the core, is a powerful virtualization solution that enables efficient resource consolidation, utilization, dynamic provisioning, and integrated systems management. XenServer Dell Edition has a small footprint and is optimized to run from an internal flash storage in Dell PowerEdge™ systems. For added flexibility, you can also install XenServer Dell Edition on a hard drive.
• High Availability — XenServer Dell Edition supports several features to guarantee service uptime in the event of infrastructure failure. You can configure resource pools for automated high availability. For example, in the case of individual host failures, you can move VMs running on the failed hosts to the next available system in the resource pool and restart them.
• Improved XenServer updates — To improve reliability of software upgrades, the XenServer Dell Edition image contains a primary and secondary copy of the XenServer file system. At any time when an update is applied, only the secondary copy is updated, leaving the primary copy in a known good state. The secondary copy now becomes the primary image. You can update the XenServer host by using the XenServer local console or XenCenter. NOTE: You can upgrade the XenServer host to release 5.5.
Citrix XenServer Dell Edition is pre-installed on PowerEdge systems. You require a license key to enable Citrix Essentials for XenServer Dell Enterprise Edition. If you purchased Citrix Essentials for XenServer Dell Enterprise Edition, you must redeem the activation code from the license card you received with your system. You must redeem your authorization code(s) for Enterprise license files from the Citrix Dell Edition Product Gallery website at citrix.com/xenserver/dell.
In general, when you install VMs, ensure that you follow the memory and disk-space guidelines of the operating system and any relevant applications that you want to run. For information on the recommended memory and disk-space guidelines, see the XenServer Virtual Machine Installation Guide available on the Citrix XenServer Dell Edition website at citrix.com/xenserver/dell.

Systems Management Using Dell™ OpenManage™ Dell OpenManage Systems Management software suite is a suite of system management applications for managing Dell PowerEdge™ systems. This section lists the features available in OpenManage that are supported in Citrix® XenServer® Dell Edition. This section also points out specific tasks that are not supported. For more information on each of these features, see the Dell Systems Management: OpenManage website at dell.com/openmanage.
There are several sub-components in OpenManage Server Administrator which are described below. • Instrumentation Services — Provides hardware instrumentation and configuration information. • Storage Management — Provides monitoring and instrumentation of the storage connected to the Dell PowerEdge RAID Controller (PERC) and Serial Attached SCSI (SAS) families of controllers.
Dell Systems Build and Update Utility The Dell Systems Build and Update Utility provides functionality to update and deploy Dell systems. It contains basic functionality provided by OpenManage Server Update Utility and OpenManage Deployment Toolkit. The Dell Systems Build and Update Utility can be used to update the system firmware, configure system components such as DRAC and iDRAC, and configure RAID groups through a graphical interactive wizard.
IPMI Baseboard Management Controller IPMI Baseboard Management Controller (BMC) provides a standard interface for monitoring and managing Dell systems. Using Dell OpenManage in Citrix XenServer Dell Edition Environment Dell OpenManage Server Administrator components are pre-installed in Citrix XenServer Dell Edition and cannot be uninstalled or reinstalled. By default, all installed OpenManage Server Administrator services start when the XenServer host boots.
To connect to the XenServer host and access the OpenManage Server Administrator web-based interface, type the following web address in a supported browser window from a client system: https://:1311 NOTE: 1311 is the default port used by the OpenManage Web server. The XenServer host firewall is pre-configured to allow ports used by OpenManage Server Administrator, so no additional firewall configuration is required.
Using ITA in a Citrix XenServer Environment ITA can be used for discovery, monitoring, and management of XenServer hosts. ITA uses Simple Network Management Protocol (SNMP) to manage Dell systems running Citrix XenServer Dell Edition. To manage XenServer hosts using ITA, follow the steps below: 1 Specify SNMP community name: Log in to the XenServer local console shell and edit the following entries in the /etc/snmp/snmpd.
Change Management in XenServer Dell Edition Dell Update Packages for supported PowerEdge systems are available for download from the Dell Support website at support.dell.com. ITA provides a centralized software update capability. You can load Dell Update Packages and System Update Sets (system bundles) into the ITA repository, either from the Dell Server Updates media or from the Dell Support website. You can also apply updates individually on each XenServer host.
You can also upload the update package to the XenServer host using a file transfer program and then run the package. Log in to the XenServer host as a root user and perform the following steps: 1 Upload the update package (*.BIN file) to /var/tmp. 2 Login to the XenServer local console shell. 3 Run the BIN file that you downloaded. 4 Follow the instructions provided by the update package. 5 Reboot the system if required by the update package.
Configuring Storage Local Storage Repository (SR) Configuration A local storage repository (SR) is a storage for virtual machines (VMs) on the local hard disk drives of a Dell™ PowerEdge™ system. Depending on the storage configuration of the system, a local SR may be automatically created during the Citrix® XenServer® Dell™ Edition first boot.
Creating a Volume Using Dell OpenManage Server Administrator Storage Management You can create a new storage volume or virtual disk on the disks attached to Dell PowerEdge RAID Controller(PERC) or Serial Attached SCSI (SAS) storage controllers, as illustrated in Figure 5-1, using OpenManage Server Administrator Storage Management. To create a new virtual disk, follow the steps in the Dell OpenManage Server Administrator Storage Management User's Guide available on the Dell Support website at support.dell.
Figure 5-1. Create Virtual Disk Using Dell Open Manage Storage Manager Figure 5-2.
Deploying XenServer Dell Edition With Dell Storage Arrays This section describes deployment steps to use the Dell PowerVault™ and Dell EqualLogic™ storage arrays with Citrix XenServer Dell Edition. Dell PowerVault MD1000 and PowerVault MD1120 Storage Enclosure • The PowerVault MD1000 storage enclosure is capable of housing up to fifteen 3.5-inch disk drives. This direct-attached storage enclosure supports both SAS and Serial ATA (SATA) disk drives.
PowerVault MD3000 RAID Enclosure The PowerVault MD3000 RAID enclosure is designed for high availability, offering redundant access to data storage. It features dual active or active RAID controller modules, redundant power supplies, and redundant fans. The PowerVault MD3000 RAID enclosure is designed for high-performance environments that includes either of the following: • Two-node fully redundant XenServer hosts • Multi-host storage access for up to four servers.
Creating an SR on a PowerVault MD3000 RAID Enclosure Follow the steps below to create an SR on a storage volume on a PowerVault MD3000 RAID enclosure. 1 Create and configure a virtual disk using the PowerVault MD3000 MDSM software (installed on your management station). Ensure that the newly-created virtual disk is controlled by the RAID controller to which your XenServer hosts have access. 2 Map the newly-created virtual disk to the XenServer hosts.
Note the SCSI device name (/dev/sdX) and find the corresponding disk ID in the output of the following command: # ls -ltr /dev/disk/by-id The output of this command is similar to one below: scsi-36001c23000c967da00000bae47ecaeeb -> ../..
XenServer Dell Edition comes pre-installed with the open-iSCSI initiator that can be used to connect to PowerVault MD3000i storage arrays. Alternatively, a software iSCSI initiator inside a virtual machine (VM) can be used to add a storage volume from PowerVault MD3000i storage array. By default, the physical network interface on which the XenServer management interface is configured is chosen to route the IP storage traffic.
4 Run the Modular Disk Storage Manager and manually add the XenServer host(s) based on the new iSCSI IQN entered in step 1. After opening the MDSM and selecting the PowerVault MD3000i storage array to be configured, select the Configure tab. NOTE: In the examples to follow the storage array “sg23_training” is a PowerVault MD3000i storage array with virtual disks already configured using the Create Virtual Disks selection. The new system being added to an existing host group is named Valhalla.
8 Select Yes: This host will share access to the same virtual disks with other hosts and determine which of the following two options applies to your host group: a If you want a new host group, select the radio button for that option and enter a name for your host group using standard host naming conventions. For example, no spaces. b If you have already created one or more host groups, select the radio button enabling selection from a drop-down menu that lists the existing host groups.
10 Select Finish to confirm the new host definition. This initiates the wizard configuration of the new host. 11 On completion, select Yes to proceed to the next host you wish to configure, or select No to end the configuration wizard. 12 Return to XenCenter and create a new SR by connecting to the desired XenServer host and clicking on its Storage tab. 13 Click Add, choose the iSCSI radio button for Virtual disk storage, and click Next. 14 Enter the name for the new SR in the Name field.
can be configured to segregate storage traffic from management traffic. See "High Availability Configuration and IP Storage Traffic Segregation" on page 49 for more details on specific configuration steps. Creating a Storage Repository on Dell EqualLogic PS Series Arrays With XenServer, two types of SRs can be created on PS Series arrays: • LVM Over iSCSI (lvmoiscsi) SRs utilize the Linux Volume Manager (LVM) to create a logical volume per virtual disk image (VDI).
6 Click Discover IQNs to perform target discovery. Each volume on an EqualLogic array has a unique target name with LUN ID set to "0". 7 Select the appropriate IQN and then click Discover LUNs to discover the LUN associated with the target. 8 Select the LUN and click Finish to create a new SR. Creating an EqualLogic (Equal) SR NOTE: To use an EqualLogic SR, the firmware version of the PS Series array must be 4.0.1 or higher.
7 Click Thin Provisioning for all volumes associated with the new SR, if desired. 8 Click Finish to create the new SR. For more information on using the XenServer EqualLogic Storage Adapter, see Using Dell EqualLogic PS Series Arrays with XenServer available on the Dell- Virtualization with Dell and Citrix website at dell.com/xenserver.
Resizing An SR After Changing the Size of An LVM-Based Storage Volume If you change the size of a LVM-based volume (SAS, iSCSI, or Fibre Channel)—for example, if you increase the size of the volume on your iSCSI storage array—the size of the SR on that volume does not get updated. To adjust the size of the SR: 1 Turn off all virtual machines on the SR. 2 Note the universally unique identifier (UUID) of the SR. Run the xe sr-list command on the XenServer host and identify the SR by its name label.
6 Find the physical volume device SCSI device mapping name on which the SR exists. Identify the volume group (VG) corresponding to the SR. Run the following command on the XenServer host: # pvs The output of this command is similar to the output given below: PV Fmt VG Attr PSize PFree /dev/sdd VG_XenStorage-058e9a1d-9b7e-71bc7a4c-5b78d6e30bcb lvm2 a80.00G 38.00G /dev/sde VG_XenStorage-4684b6c6-be6d-6267b7b5-834a1fd30f65 lvm2 a59.99G 45.99G The volume groups (VG) are named as VS_XenStorage-.
Recovering the Citrix® XenServer™ Host Whenever possible, leave the installed state of Citrix XenServer Dell™ Edition unaltered. Treat the XenServer hosts as if they are appliances and do not install any additional packages or start additional services on them. XenServer uses a per-host database to store metadata about virtual machines (VMs) and associated resources, such as storage and networking.
4 You are prompted to provide a filename for the backup. Type the desired filename and press . The backup file is written to the selected media. 5 Remove the media with the backed-up file and store it in a safe place. When required, you can use this media to recover the XenServer state.
Restoring the XenServer Database After you restore the XenServer host to the factory-default configuration, restore the backed-up XenServer database to regain your VMs and the particular network and storage configuration. This process differs depending on whether you have a single host or a resource pool, and whether the restored XenServer is to be a member or master of the pool. For the default case, you can use the XenServer local console.
Recovering XenServer After a Board Replacement In the event of a motherboard change in your XenServer host, the system service tag must be reset to its original value for XenServer to function. Download the latest asset.com utility from ftp.us.dell.com/utility. In the DOS prompt, type asset.com /s . Resetting the Root Password If you lose or forget the root password, you can reset it using the XenServer Dell Edition Recovery Media.
Best Practices High Availability Configuration and IP Storage Traffic Segregation • High Availability — Use Citrix® XenCenter® to create a network interface bond using two NIC ports. This provides high availability for storage traffic. • IP Storage Traffic Segregation — To segregate IP storage traffic, create a new host interface. In XenCenter, click on the host and select Management Interfaces.

In the Run field, enter the path to the batch file followed by the hostname or IP address, username, and password.
Using Storage Array Snapshots for LVM-Based Storage Repositories Using storage array snapshot features available on the Dell™ PowerVault™ MD3000, MD3000i and Dell EqualLogic® storage arrays, a point in time copy of the Logical Volume Manager (LVM) based storage repositories can be taken for tasks such as backup, data mining, reporting, testing software upgrades, etc., in the virtual machines (VMs). A typical operation involves: • Taking a snapshot of the storage repository (SR).
Shut Down VMs Before a Snapshot In scenarios where you cannot achieve application consistency using frameworks such as Microsoft VSS or VDS, etc., you can create a snapshot or clone of an SR when VMs are powered down and ensure a volume recovery that is clean. Scenarios where all virtual disks of a VM are virtualized through the XenServer domain fall into this category.
3 Take a snapshot of the SR and the Suspend SR if it is different from the SR for which the snapshot was created. 4 Power on the VMs on the primary XenServer host. 5 Attach the snapshot of the SR and Suspend SR if it is different from the SR for which the snapshot was created on the secondary XenServer host. 6 Restore the VM metadata to the recovered VMs. 7 Boot the VMs on the secondary XenServer host.
Attach the SR Snapshot to the Secondary XenServer Host Make the snapshot volume available to the secondary XenServer host by attaching the SR. For snapshots of iSCSI volumes, just attach the SR to the XenServer host using XenCenter. If the snapshot resides on a Dell PowerVault™ MD3000 RAID enclosure, follow the steps below to attach the snapshot as an SR to a XenServer host. 1 Note the universally unique identifier (UUID) of the SR for which the snapshot was created.
Restoring VM Metadata to Recover VMs from a Snapshot To restore the VM metadata to recover VMs from a Snapshot: 1 Access the Backup, Update and Restore menu in the local console on the XenServer host or pool master. 2 Perform a metadata restoration operation using the Restore Virtual Machine Metadata menu option.
Adjusting SCSI Timeouts for the PowerVault MD3000i Storage Arrays If the XenServer host is connected to the PowerVault MD3000i storage arrays, on the XenServer host, you can change the SCSI timeout value for the SCSI device(s) on the PowerVault MD3000i storage arrays. Follow the steps below: 1 Create a new udev rule file with name 96-md3000i-sto.rules at /etc/udev/rules.
Appendix Citrix® XenServer™ Dell™ Edition Local Console Menu Items The host local console can be used to configure the Citrix XenServer Dell Edition and to set up storage repositories (SRs) for virtual machines (VMs).
