XCP SMB uses Windows client host systems to generate parallel I/O streams and fully use available network and storage performance.

Configure storage

XCP SMB transitions and migrations have the following user login requirements:

  • XCP host system: An XCP host user must have administrator privilege (the user must be part of the "BUILTIN\Administrators" group on the target SMB server).

  • Add the migration or XCP host user to the audit and security log policy for Active Directory. To locate the 'Manage Auditing and Security Log' Policy on Windows 10, follow these steps:

    1. Open the Group Policy Editor dialog box.

    2. Go to Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment.

    3. Select Mange auditing and security log.

    4. To add an XCP host user, select Add User or Group.

      For more information, see: Manage auditing and security log.

  • Target storage system: XCP host user must have read and write access.

  • Source storage system:

    • If the user is part of the “Backup Operators” group in the source storage system, the
      members of this group can read files while bypassing the security rules,
      regardless of any permissions that protect those files.

    • If the user is not part of “Backup Operators” group in source system, the user
      must have read access.

Note Write permission is required in the source storage system for supporting the XCP option - preserve-atime.

  • Add the destination storage box and the source storage box to the host file:

    1. Navigate to the following location: (C:\Windows\System32\drivers\etc\hosts)

    2. Insert the following host entries to the file in the following format:

      <Source data vserver data interface ip> <Source cifs server name>
      <Destination data vserver data interface ip> <Destination cifs server name>
