EMC D-PWF-DS-23 Exam Dumps - Actual Questions Answers

For a PowerFlex system that requires compression, the necessary components include NVDIMMs and a storage pool with fine granularity. Here’s why these two components are required:

• NVDIMMs: Non-Volatile Dual In-line Memory Modules (NVDIMMs) provide high-speed DRAM performance coupled with flash-backed persistent storage. They are used specifically for compression on PowerFlex storage-only nodes. At least two NVDIMMs per server are required if storage compression is active1.
• Fine Granularity Storage Pool: Inline compression in PowerFlex is enabled when using the fine-granularity data layout for storage pools. This granularity level allows for more efficient data compression and storage optimization2.

These components work together to enable compression in the PowerFlex system, ensuring efficient storage utilization and performance. The use of NVDIMMs for compression enhances the system’s ability to handle the additional workload associated with compressing data, while the fine granularity storage pool provides the necessary structure for data layout that supports compression12.

The maximum number of Storage Data Servers (SDSs) per protection domain in a PowerFlex rack is 1283. This is specified in the PowerFlex specification sheet and ensures that each protection domain can provide data protection for a significant number of SDSs, allowing for scalability and resilience within the PowerFlex infrastructure.

The correct sequence of steps to set up remote replication on the PowerFlex system is as follows:

• Install target PowerFlex system: Before replication can be set up, there must be a target system in place to receive the replicated data1.
• Exchange root certificates: This is a security measure to ensure that communication between the source and target systems is secure1.
• Add a Replication Peer: This involves configuring the target system as a replication partner in the source system’s configuration1.
• Configure replication volumes: Finally, specific volumes on the source system are configured to replicate to the target system1.

Setting up remote replication in a PowerFlex system involves a series of steps that establish the necessary components and configurations for the replication process. The sequence begins with the installation of the target PowerFlex system, which will serve as the destination for the replicated data. Next, root certificates are exchanged between the source and target systems to ensure secure communication. The target system is then added as a Replication Peer within the source system’s configuration. Lastly, the volumes intended for replication are configured on the source system to complete the setup process. This sequence ensures that the replication is secure, reliable, and correctly configured to maintain data integrity and availability across both systems1.
