Dell PowerFlex 4.5.x Technical Overview
PowerFlex management platform improvements
PowerFlex 4.5 now supports several management improvements.
Stronger security
Use SSH keys and non-root users through sudo in management aspects. For more information about configuration guidelines, see the Dell PowerFlex 4.5.x Install and Upgrade Guide and Dell PowerFlex 4.5.x Administration Guide.
Webhooks
PowerFlex 4.5 enables Webhooks support by sending alerts to Webhooks servers such as BigPanda.
PowerFlex management platform deployment time
Optimization of the PowerFlex management platform installer run time to 60 minutes. In PowerFlex 4.0.x, the installer run time was 3 hours.
Multi-subnet and multi-VLAN for PowerFlex appliance and PowerFlex rack
PowerFlex 4.5 allows defining multiple subnets and VLANS in a single network. The most common implementation example is with a management or vMotion network that spans multiple racks. Each rack is its own subnet and VLAN.
NOTE:This capability is supported on all networks except for the following:
- PowerFlex data
- vSAN and NSX overlay network
- NSX external networks
Higher flexibility of fault sets
PowerFlex 4.5 defines a subset of nodes in a rack as part of a fault set during deployment and expansion operations. For example, a rack with 20 nodes can have four fault sets, one for every five nodes, for easier maintenance support. Another option is using fault sets in a full rack configuration, such as one fault set per rack.
PowerFlex management controller self-awareness on PowerFlex appliance and PowerFlex rack
PowerFlex 4.5 allows self-awareness of its underlying controller system. Upgrade from end to end and receive alerts from issues in the PowerFlex management controller infrastructure.
Modular (single) component upgrade
PowerFlex 4.5 changes the package in the PowerFlex rack or PowerFlex appliance catalogs to newer or older versions. This upgrade depends on customer cases that want to deviate from the Release Certification Matrix or Intelligent Catalog.
NOTE:By default this feature is turned off and can only be enabled through an RPQ process. If applicable, contact your account team for details.
