Dell SCv2020 LUN

We have a Dell SCv2020 as a main storage for all VMs.

I always think what will be the best way to recover if Dell SCv2020 dies all of a sudden.

We do have a backup of all VMs in NAS but in case Storage dies how can we get up and running in less time?

Is Dell SCv2020 replication to another SCv2020 is the solution?

Do we need replication license from Dell to have replication?

Many thanks.

  • The SCv2020 can replicated to any other SC in a "asynchron" best effort manner
  • You you need a Replication License
  • The SCv2020 have at least one dedicated (iSCSI) Replication port. Its near the MGMT port IIRC
  • Both replication partners should run the same version of SCOS

I have a customer where we replicate between SCv2020 and SCv3020

Note: All Dell SC is End of sale since 2 years.  Buying additional parts and software? will end in 8/2024.  There will be no vSphere 8 support.  Our SCv2020 are up to 7years old now and runs out of support. 

You should not spend money on a dead horse.

Change the LUN Used by a Volume/Server Mapping

The logical unit number identifies the volume to the server operating system.

  1. Expand the Dell Storage Manager menu, and then click Storage.
  2. In the SC Series tab, select a Storage Center.
  3. Click the Storage tab.
  4. In the Storage tab navigation pane, click the name of the volume you want to unmap from a server to open the Volume view.
  5. Click the Mappings tab.
  6. Select the server for which you want to modify mapping settings, then click Edit. The Edit Volume Mapping Settings dialog box opens.
  7. Configure the LUN settings:
    • To specify a specific LUN number, clear the Use next available LUN check box, then type the LUN in the LUN to use when mapping to Volume field.
    • To assign the next unused LUN for the server, select the Use next available LUN check box.
    • To make the volume bootable, select the Map volume using LUN 0 check box.
  8. When you are finished, click OK.....

Yes, Dell SCv2020 replication to another SCv2020 is a viable solution for disaster recovery and business continuity.  

Regarding the license:

Yes, you do need a replication license from Dell to enable replication functionality on your SCv2020 storage systems. This license typically covers features like asynchronous replication, synchronous replication, and data instant replay, which are essential for effective disaster recovery and business continuity.  

It's crucial to consult with Dell or your authorized Dell partner to determine the specific licensing requirements based on your exact replication needs and the number of volumes or LUNs you intend to replicate.

Additional Considerations:

  • Network Connectivity: Ensure reliable network connectivity between the two SCv2020 systems, including sufficient bandwidth and low latency.
  • Storage Configuration: Proper configuration of storage pools, volumes, and replication policies on both systems is essential.
  • Testing and Validation: Regular testing of the replication setup is crucial to verify its effectiveness and identify any potential issues.

By following these guidelines and obtaining the necessary licenses, you can effectively implement SCv2020 replication to safeguard your critical data and ensure business continuity.
