• Total Storage Pools

  Provides the number of storage pools in the resource group. If the resource group has storage pools, PowerFlex Manager also lists the granularity setting and acceleration pool for each storage pool.

  In PowerFlex, the storage pools enable the generation of different storage tiers. A storage pool is a physical storage device in a protection domain. Each storage device belongs to one (and only one) storage pool.

  The resource group deployment results in the creation of a separate storage pool for each type of disk (SSD/NVMe or hard drive) found in the nodes. The deployment process adds the disks from the nodes to the appropriate storage pools based on the expected types for each pool.

• Protection Domain

  In PowerFlex, a protection domain is a logical entity that contains a group of Storage Data Servers (SDSs) that provide backup to each other. Each SDS belongs to one (and only one) protection domain. Each protection domain is a unique set of SDSs. It may also contain SDTs and SDRs.

View the following information about the CloudLink Centers participating in the resource group:

• Health
• Hostname
• Management IP
• Machine Group
• Keystore

When a resource group is deployed, if CloudLink has clustered CloudLink Centers, PowerFlex Manager shows all CloudLink Centers on the Resource Group Details page. PowerFlex Manager ensures that the resource group deployment succeeds as long as at least one CloudLink Center in the cluster is working.

• iDRAC IP/Hostname
• PowerFlex Mode

  The mode for each node is one of the following:

  • Hyper-converged includes both SDS and SDC components.
  • Storage Only includes only the SDS component.
  • Compute Only includes only the SDC component.
• MVM Hostname

  For a hyperconverged resource group, PowerFlex Manager adds IP addresses for the MVM to the node IP list. PowerFlex Manager appends (MVM) to all network names for the MVM. If there are no MVM hostnames, the MVM Hostname column is not shown.

• Associated IPs
• MDM Role

  The MDM role is the metadata manager role. The MDM role applies only to those nodes that are part of a PowerFlex cluster. The MDM role is one of the following:

  • Primary: The MDM in the cluster that controls the SDSs and SDCs. The primary MDM contains and updates the MDM repository, the database that stores the SDS configuration, and how data is distributed between the SDSs. This repository is constantly replicated to the secondary MDMs, so they can take over with no delay.

    Every PowerFlex cluster has one primary MDM.

  • Secondary: An MDM in the cluster that is ready to take over the primary MDM role if necessary.
  • Tie Breaker: An MDM whose sole role is to help determine which MDM is the primary.
  • Standby MDM: A standby MDM can be called on to assume the position of a manager MDM when it is promoted to be a cluster member.
  • Standby Tie Breaker: A standby node that is prepared to take over as a tiebreaker.
• Fault Set: A logical group of SDSs within a protection domain that defines by the way it is grouped where the copies of data exist. If there is no fault set, this column is not shown.
