NetBackup Appliance version 3.1.2  

NetBackup Appliance version 3.1.1

Description: 

This EEB is for performance setting required on Netbackup Appliance. These settings are independent of hardware Model (5230/5330/5240). 

Action taken: 

When installed, the EEB will set below four parameters in sysctl.conf and one in spoold. Reload of sysctl.conf will be done at the end of this EEB install. Restart of NetBackup Service may occur depending on kernel.numa_balancing value. 

vm.min_free_kbytes 

vm.swappiness 

kernel.numa_balancing 

overcommit_ratio   

Note: overcommit_ratio will also be set in spoold to ensure value across reboots 

Below are the details for values set for these parameters: 

• vm.min_free_kbytes setting is based on memory the appliance server has. If the server has less than 256G, the EEB will set vm.min_free_kbytes to 2G. If the server has more than 256G the EEB will set the vm.min_free_kbytes to 4G.  Servers with more than 256G do not require a value greater than 4G.  
• overcommit_ratio =100  
• vm.swappiness =1 
• Kernel.numa_balancing =0 

During EEB installation a check will be done to determine kernel.numa_balance value.  If kernel.numa_balance is already set to 0, no change will be made to this parameter. If the kernel.numa_balance is set to anything other than 0, the EEB will change the value to 0. Restart of NetBackup services is needed to reflect this parameter change.
