- Minimum number of nodes for production workload is seven for a PowerFlex two-layer configuration in a VMware environment.
- Homogenous node types are recommended for predictable performance. With homogeneous compute nodes and homogeneous storage nodes, compute, and storage do not must be the same.
- Change the passwords for all default accounts.
- Ensure PowerFlex rack is compliant to an RCM. For more details, see PowerFlex specification sheet.
- Enable secure network protocol options only (for example, HTTPS and Secure Shell (SSH).
- Number of SDS threads set to 12 for all the SO nodes
- Separate management and data traffic from production application traffic. You can provide this separation by using VLANs.
- Separate VMware vSphere vmotion traffic from application traffic according to PowerFlex standards
- Change the following Linux grub settings for Skylake processor to comply with performance best practices and rebuild the grub boot image:
rd.lvm.lv=rhel/swap rhgb intel_idle.max_cstate= 1 intel_pstate=disable quiet"
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg
- When PowerFlex SSD drives are used, it is recommended to use noop for Linux I/O scheduler on SDC hosts. To make the changes persistent through boot add elevator=noop to GRUB_CMD_LINUX line and rebuild the grub boot image. For example:
rd.lvm.lv=rhel/swap rhgb quiet elevator=noop"
