Build-your-own (BYO) server prerequisites and hardware requirements to configure universal shares

The following are prerequisites for using the universal share MSDP build-your-own (BYO) server feature:

  • The universal share feature is supported on an MSDP BYO storage server with Red Hat Enterprise Linux 7.6 or later.

  • The universal share feature is not supported on SUSE Linux.

  • You must set up user authentication for the universal share.

    See Configuring universal share user authentication.

  • NFS services must be installed and running if you want to use the share over NFS.

    Ensure that the nfs-utils is installed:

    • Red Hat: yum install nfs-utils -y

  • Samba services must be installed and running if you want to use share over CIFS/SMB.

    Ensure that the Linux samba and samba winbind packages are installed.

    • yum install samba samba-common samba-winbind samba-winbind-clients samba-winbind-modules -y

  • You must configure Samba users on the corresponding storage server and enter the credentials on the client.

    See Configuring universal share user authentication.

  • Ensure that the xfsprogs is installed:

    • Red Hat: yum install xfsprogs -y

  • Ensure that the following commands are run to grant permissions to the SMB shares:

    • setsebool -P samba_export_all_rw on

    • setsebool -P samba_export_all_ro on

  • Install and run NGINX. The minimum recommended NGINX version is 1.24.0.

  • After NGINX is installed, the HTTP web service at port 80 is enabled by default. Remove /etc/nginx/conf.d/default.conf or edit the file to disable the HTTP web service if it is not needed.

  • Ensure that the /mnt folder on the storage server is not directly mounted by any mount points. Mount points should be mounted to its subfolders.

  • Ensure that you configure the storage server for MSDP. If you configure the universal share feature on BYO after storage is configured or upgraded without the NGINX service installed, run the command on the storage server:

    /usr/openv/pdde/vpfs/bin/vpfs_config.sh --configure_byo

  • Ensure that the required network ports are open.

    See "NetBackup media server ports" in the NetBackup Network Ports Reference Guide.

Table: Hardware configuration requirements for universal shares on a Build Your Own (BYO) server

CPU

Memory

Disk

  • Minimum 2.2-GHz clock rate.

  • 64-bit processor.

  • Minimum 4 cores; 8 cores recommended. For 64 TBs of storage, the Intel x86-64 architecture requires eight cores.

  • Enable the VT-X option in the CPU configuration.

  • 16 GB (For 8 TBs to 32 TBs of storage - 1GB RAM for 1TB of storage).

  • 32 GBs of RAM for more than 32 TBs of storage.

  • An additional 500MB of RAM for each live mount.

Disk size depends on the size of your backup. Refer to the hardware requirements for NetBackup and Media Server Deduplication Pool (MSDP).

If a system has multiple data partitions, all the partitions must be the same size. Example: If a BYO server has a first partition at 4TB, all additional data partitions must be at 4TB in size.

NetBackup upgrades

You must unmount all the NFS mount points on the client side before you upgrade to NetBackup to avoid issues when accessing the universal share on the client side over NFS.

Note:

The CIFS/SMB shares do not require these operations.

  1. Unmount all the universal share that were mounted on the Linux UNIX client.

  2. Upgrade to NetBackup.

  3. Start the NetBackup services.

  4. Mount the universal share again on the Linux UNIX client.
