Each question shows the correct answer and an explanation of why it is right
Shared file systems in PowerFlex allow data sharing across multiple nodes. True or False?
This refers to PowerFlex File (formerly PowerFlex NAS).
While the core PowerFlex product is a block storage solution (providing raw LUNs/Volumes which cannot be safely shared by two standard OS hosts without a cluster file system like VMFS or OCFS2), PowerFlex File introduces NAS nodes. These nodes format the block storage and present it via NFS or SMB protocols. These protocols are specifically designed to allow multiple clients to read and write to the same file system concurrently, enabling true data sharing across the network.
What is the minimum number of nodes required to create a Storage Data Server (SDS)?
3 Nodes: While you can technically install the SDS software on a single server, to create a functioning Storage Pool and a valid PowerFlex cluster that supports the standard 2-copy mesh-mirroring protection scheme, a minimum of 3 SDS nodes is required.
Why? Data is divided into chunks (Primary and Secondary).
Chunk A Primary goes to Node 1.
Chunk A Secondary goes to Node 2.
If Node 1 fails, the system needs a third node (Node 3) to rebuild the missing copy from Node 2 to restore redundancy. A 2-node cluster cannot rebuild data if one node fails (nowhere to put the copy), leaving it permanently degraded.
Which component is reconfigured when expanding metadata storage in PowerFlex?
Metadata in PowerFlex is not stored in the general user Storage Pools; it is managed and stored by the Metadata Manager (MDM) cluster.
When a PowerFlex cluster grows significantly (e.g., increasing from 1000 to 100,000 volumes, or adding hundreds of nodes), the metadata usage increases.
Expanding Metadata Capabilities: You do not 'expand' a metadata pool like you do a storage pool. Instead, you might reconfigure the MDM Cluster itself. This could involve moving from a 3-node MDM cluster to a 5-node MDM cluster to distribute the processing load, or replacing the MDM nodes with hardware possessing larger RAM and faster CPUs.
Therefore, the component being reconfigured to handle this growth is the Metadata Manager (MDM).
Which logical entity is used to group Storage Data Server (SDS) nodes for fault isolation and resource management?
The Protection Domain (PD) is the highest level of logical aggregation for storage nodes in PowerFlex.
Fault Isolation: The Protection Domain acts as a 'walled garden' for failures. If a catastrophic failure occurs (e.g., a power outage affecting a specific rack), the impact is contained within that Protection Domain. Data replication and rebuilding occur within the boundaries of the PD. An SDS in Protection Domain 1 cannot mirror data to an SDS in Protection Domain 2.
Resource Management: Administrators manage resources at the PD level to balance the cluster. For example, a cluster might have one Protection Domain for 'High Performance Flash' nodes and another PD for 'High Capacity HDD' nodes.
Differentiation:
Storage Pools exist inside a Protection Domain to group disks.
Fault Sets exist inside a Protection Domain to further granularize failure zones (e.g., preventing mirroring between nodes in the same rack).
An administrator wants to secure PowerFlex user accounts by integrating with LDAP. What steps should they follow? (Choose two).
Configure LDAP server details (Option A): The administrator must navigate to the Security settings and input the IP/Hostname of the LDAP/AD server, the Base DN (Distinguished Name), and the Bind User credentials. This establishes the connection.
Test LDAP integration (Option C): Before saving and relying on the configuration, it is essential to perform a 'Test' action within the interface. This verifies that PowerFlex can reach the LDAP server and successfully query the user directory. If this step is skipped and the config is wrong, users might be locked out.
Note: Option B is partially relevant but usually automated via 'LDAP Group Mapping' rather than defining individual local RBAC roles for every LDAP user.
