What is new in StruxureWare Data Center Operation 8.2.12

Change Request

This new functionality enables users to request changes to the data center through custom build change request forms called Change Request Templates.


Change Request requires StruxureWare Data Center Operation: Change License

Change request templates

Change request templates are managed by Administrators (users with permission "Planning Work Orders") to prepare a Request Form in the DCO web client using the Change Management > Change Request Templates option. The Request Form is then filled in by users to request changes in the data center.

Each template has a NameActivation state, and Form field to specify information about the change. Templates are flexible; multiple templates can be defined in the system. For example, you can create a template for adding equipment, another for moving items, and another for creating users or custom properties.

Administrators can create, edit, delete, activate, or deactivate a template. Only active templates can be used to create change requests.

Form fields that can be used in the template (and then in the change requests):

  • Text input
  • Numeric input
  • Date input
  • Multi-line text field
  • Email input
  • Checkbox
  • Select input (combo box)
  • Radio button
  • Header
  • Genome selector
  • Location selector
  • Blank space - separator

The Genome selector allows you to specify the equipment model from the Custom Catalogue. This is useful for creating a template for adding equipment. You can specify the kinds of equipment (PDU, UPS, Server) and/or mounting types to select in the field.

Three value fields are available for publishing properties from a work order task to an asset: BarcodeSerial number, and Name.

You can use the Location selector to select the existing LocationFloor Plan, or Room from the data set.

You can define basic validation on each field to prevent users from submitting a change request with incorrect or missing information. For example, each field can be made optional or required; text fields can have a minimum or maximum length. When you edit the template form, you can enter values into the fields to see how they work. These values are not persisted.

The Administrator can define the form layout for four different screen sizes to make the form adjustable to the user's screen size when they are creating or editing a change request.

Creation, deletion, and editing change request templates are logged by the Audit log and can be verified in the desktop client by running the report.

Change Requests

A change request can be created by all non-tenant users in DCO based on templates created by an Administrator (a user with permission "Planning Work Orders") in the DCO web client: Change Management > Change Requests

A typical scenario:

  1. A user creates a change request, and fills in the form. The change request can be saved as Draft.
  2. Draft or a newly created request can be Submitted if all fields are filled in according to the validation specified in the form.
  3. The Submitted request is read-only and waits for an Administrator to act. The request can be Unsubmitted by the author if some corrections need to be done, which puts it back into Draft.
  4. The Administrator can do one of three operations on a Submitted change request:
    • Approve: The Administrator has accepted and processed the request, for example, by creating a work order for executing the change.
    • Reject: Indicates the change is impossible to complete.
    • Require more information: The request status is changed to Need update. The author can modify the form data and resubmit the request.
    • Closed: The final step, used when the request has been executed. The request can then be deleted by the author or the Administrator.


Requests in Draft state are only visible to the author; they are not visible to other users.

Requests in other states are visible only to the author and Administrators.

If the author of a request is removed from the system, requests in Draft and Needs Update states are deleted. Requests in SubmittedRejected, and Approved states survive so administrators can act on them.

Requests in Approved state

If a request contains one Genome, the Admin can Copy Genome Properties to populate properties from the Genome in the request to an asset in an open work order. The values that are copied are: BarcodeSerial number, and Name. There is validation on the barcode to keep it unique in the model. 

Note: The work order must be created in the DCO desktop client.

You can comment on requests in states other than Draft to allow further communication between the author and the administrator.

When a request changes state, or a comment is posted, a notification email is sent to interested parties:

  1. If the change or comment is made by the author of the request, email is sent to all administrators.
  2. If the change or comment is made by an administrator, email is sent to the author of the request.

Email is sent in the user’s preferred language.

Note: You must configure mail settings with the Mail configuration REST web service.

Creating, deleting and changing the request state is logged in the Audit log. You can run a report in the desktop client to view the audit log.

Barcode lock feature

When you import data via ETL, you can configure the option to lock the bar code, serial number, and name fields to avoid data changing from a synchronisation.

Improvements to reports

The U-space report was updated to include full-depth U-space. Free front, rear, and full depth U-space is now included in the report.

The Forecast report now includes the power capacity for planned changes in a room based on work orders.

Server management options moved from Webmin to the web client

The management of backup and restore have been moved to the new Backup and Restore page in the web client. See the updated backup and restore documentation here Backup and Restore.

Server log files can now be downloaded from the Download Server Log files page in the web client.

ETL and Power Monitoring Expert integrations can now be configured from the web client. See the updated documentation here ETL configuration.

Other changes

  • ITO log files have been removed from DCO.
  • The ITO server must now be backed up separately.
  • The ZipSlip vulnerability (CVE-2018-7806) has been fixed. CVSS score: 6.6, CVSS vector: AV:A/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H. The issue affects all previous versions.
    • ZipSlip vulnerability allows authenticated users to upload malicious file which could contain path traversal file names, this could potentially allow for the arbitrary upload of files contained with the zip onto the server file system outside of the intended directory. See more on the StruxureWare Data Center Operation Software Vulnerability Fixes page.

What is new in StruxureWare Data Center Operation 8.2.7

 Extended power capacity information for rack mount PDUs in the web client

Extended power capacity information for rack mount PDUs in the web client

When you select a rack that contains items that report measured values, the Power tile displays the total of all the maximum values for a time specified in the desktop client. This is now labeled Theoretical Peak (Theo. Peak) rather than Measured Peak.

Click the Power tile to view the Power History and Power Path Items for the rack.

The Power Path Items section contains tiles for each rack mount PDU. No tiles are displayed for disconnected rack mount PDUs.

In the Power Path Items section, click the tile for the rack mount PDU, then click the Power tile to view its power capacity charts.

Note: This information is also available in the desktop client tool tips.

The Power chart shows calculated values per phase: measured peak power per phase, estimated load, and potential failover load. A bar indicates the physical limitations of the device.

The Power History charts shows the measured values in more detail. You click the items in the legend to show and hide values.

 User messages

User messages

Administration > User Messages option

In a Colocation environment, DCO admin users or operations users with a Colocation license can create messages to be displayed to tenants.

When you create a message, you choose the date and time you want the message to be active, and the recipients you want to see it. If you do not select recipients, all users will receive the message.

You can send a message to tenants in locations or groups you select, or only some tenants in the locations or groups you select. Use the list and the search field to narrow your selection and find the tenants you want to receive the message.

Your selections are highlighted with a green bar. Click Show selected to see the list of tenants you chose to receive the message.

When the tenant users log in, they will see the message bar at the bottom of the screen. Controls on the left side of the message minimize the message, scroll through multiple active messages, or zoom to display a long message.

 Desktop client not included with ISO

Desktop client not included with ISO

The desktop client is now hosted and is no longer included with the ISO. There is no longer a strict version number match between the server and client.

You do not always need to update desktop clients when you update your Data Center Operation server. If a client update is required, a message will appear when you start the client for the first time after updating your server. The desktop client now seamlessly handles new server versions by downloading the required files the first time it connects to the server. The desktop client stores files for each version and use the files corresponding to the server version it connects to. There is also an option to download the desktop client in your profile in the web client.

 Clustered environment is no longer available

Clustered environment is no longer available

Clustered Environments will no longer be available as an installation option in Data Center Operation starting with version 8.2.7. Performance, uptime, and stability, especially in scalable situations, has proven to be significantly better at one node than with several in a cluster.

There are two alternatives to achieve the same results as a cluster:

  • Use EcoStruxure IT Advisor
  • Disaster recovery in StruxureWare Data Center Operation

Note: Your clustered setup will not be saved when you upgrade to version 8.2.7. You must switch to one of these two alternatives.

Existing disaster recovery node setups must be reattached after updating to version 8.2.7.


 Other features

Other features

  • The ETL password is now encrypted.

  • Active Directory integration improvements including support for mutual trust between the child and parent domain controller.

  • Vizor is no longer supported and is no longer available in the app stores.

 Require work orders to follow a process

You can now require work orders to follow a selected process in Tools > Preferences.

 Enhanced Active Directory and LDAP support

You can now add details about your Active Directory or LDAP server in the Administration > Authentication Servers option in the web client. This enables you to search the authentication server for users and groups, and to send email to individual users in work orders (if the server has a valid email for that user).

When adding a group from the authentication server (AD or LDAP) all users in that group can login to Data Center Operation, it is no longer necessary to create separate users in Data Center Operation.

 Plan floor mounted equipment

The work order functionality has been extended, so you can record putting equipment on the floor. Coordinates are used to place it and reserve the space.

 Improved Rack ATS support

Rack ATS are now modeled much better. They can be part of the power path, and the power capacity calculations take them into account. They are also shown as power assets in the Genome Library.

 Web client: Barcode scanning on smartphones

You can now scan a barcode to view a device or rack.

On Android, you tap the icon and scan the barcode to view.
On iOS, you tap the icon to take a photo of the barcode. DCO then finds the barcode in the photo. You can also use photos you already have on your device.

Note: This feature is not supported on the Safari browser in iOS 11. Use Chrome with iOS 11 instead.


 Web client: Capacity overview for locations

You can now toggle the inventory view to show either the inventory or capacity overview for the selected location.

 Web client: Branding has moved

The branding path has moved:

  • Old: /opt/jboss-as/standalone/deployments/webclient.war/web/client/css/branding
  • New: /opt/jboss-as/standalone/deployments/webclient.war/web/resources/branding

Read more on branding here: Customizing web branding

 Web client: Optimized to run on your smartphone

You can run the DCO Web client on your smartphone.

The layout scales smoothly to scale and show layout items as lists on smaller size screens rather than tiles, for example to show rooms, floor and rack layouts as listed items rather than tiles, etc.

 Platform: Information about software packages and services now available in Webmin

In the DCO server management web interface (Webmin), you can see a list of installed software packages and services on the DCO server, including version specific information.

 Download new StruxureWare Portal 1.3.6 compatible with DCO 8.0.4

There's a new version of the StruxureWare Portal available for download here.

It is compatible with DCO 8.1 and includes a fix for adding markers to location maps.

 Download links for Mobile, ITO and Server Access

Download links to StruxureWare Data Center Operation: Mobile and StruxureWare Data Center: IT Optimize and Server Access are not available from the server's download page. They are available from the same location as the DCO .iso file. You can get these through technical support.

 DCO: Genome library version specification

The latest updates to the Genome Library at the time of the release are included with the release. However, the Genome Library is continuously updated and you don't need to wait for the next release to get these updates. Regular updates to the Genome Library are available for download independently of DCO releases.

It is now possible to see your current Genome Library version specified in Preferences and in Help>About.

It is shown as a timestamp, reflecting the time when the file was developed.

 DCO: Rack layout with network routes has been improved

The graphical representation of network routes in the rack layout has been improved. When right-clicking a network cable to use the Show route feature, you would see a complicated route across multiple racks. The order of the racks in the layout has been improved.

 DCO: Excel import of manual measurements

Support has been added for importing manual power measurements into DCO through ETL.


 DCO: Excel import, auto association of devices with UUID

The equipment's UUID is included in the Excel import file (hidden column). This functionality enables the system to identify the equipment when importing and automatically associating it with the corresponding DCO model item. This means you can skip the drag'n drop device association step in the DCO layout to associate the device with the modeled item.

The functionality also works for other ETL integrations. The UUID for equipment can be found in the ETL export database.


 DCO for Colo: Customer details added for Excel import

A customer column has been added to the Excel import to store data about which customer a device with measurements is assigned to.

 Support for DCO installation on RedHat Linux

You can install DCO 8.1 on either RedHat 7.x or CentOS 7.x. See instructions for installing on RedHat.

 Support for continuous Genome Library updates



Genome Library in DCO

 Support for AD user groups

In the DCO web client user group settings, you can have both DCO user groups or AD user groups.

 Estimated load reduced on not connected 3p server

The estimated load has been reduced for a three-phase server that has not been connected for power the DCO model.

In previous versions, a three-phase 1000 W server that was not yet connected for power would have an estimated load of 3000 W because the system would account for the phase uncertainty. In DCO 8.1, the estimated load value has been reduced to 1000 W (333 W on each phase) to reduce reservation of unneeded capacity and the remaining 2000 W (666 W on each phase) will be labeled as Power Supply Unit uncertainty.

Estimated load in 8.1

 Additional fixes and improvements
  • Security: SSH configuration was hardened
  • Capacity: If your solution included tags on capacity groups, upgrading DCO from a version prior to 8.0 could cause the upgrade to fail
  • ETL: Improvements to performance when importing data through ETL
  • Tenant Portal: Cage navigation has been restored
  • External system integration: Support added for VMware 6.5

Known issues in StruxureWare Data Center Operation 8.1.x - 8.2.12
