A customer has three Dell PowerStore 1000Ts in a cluster and wants to add a PowerStore 5000X.
What must they do?

  1. Create a cluster with the 5000X.
  2. Use the PowerStore CLI to add the appliance.
  3. Reconfigure the existing cluster.
  4. Use the PowerStore Manager to add the appliance.

Answer(s): A

Explanation:

PowerStore Clustering:

PowerStore appliances can be clustered to form a single management entity. However, adding different models within the same cluster follows specific guidelines.

Cluster Compatibility:

PowerStore 1000T and 5000X are different models with potentially different hardware configurations and capabilities.

Dell recommends creating a new cluster with the PowerStore 5000X instead of mixing models within an existing cluster to ensure compatibility and optimal performance.

Adding Appliances:

Using the PowerStore CLI or PowerStore Manager to add appliances within the same model range is common, but mixing models generally requires creating a separate cluster.

Which tool can be used to migrate file data for Windows hosts from a legacy VNX array to a new Dell Unity XT array?

  1. SANCopy
  2. Rsync
  3. Robocopy

Answer(s): C

Explanation:

File Data Migration Tools:

Migrating file data from legacy systems to new arrays requires reliable tools that can handle large volumes of data efficiently.

Robocopy for Windows Hosts:

Robocopy (Robust File Copy) is a powerful command-line tool in Windows that supports extensive options for copying and synchronizing files and directories.

It is well-suited for migrating file data from a legacy VNX array to a new Dell Unity XT array, ensuring data integrity and consistency.

Other Tools:

SANCopy: Used for SAN data migration and not specific to file data.

Rsync: Commonly used for Linux/Unix systems rather than Windows hosts.

Dell Midrange Storage


Reference:

Dell Unity XT documentation and migration guides provide detailed instructions on using Robocopy for file data migration.

Community forums and support resources from Dell Technologies offer additional insights and best practices.

Which Dell Unity XT DPE front-end port connectivity can support to 45000 IOPS/port and up to 1500 MB/s?

  1. 16 Gb FC and 25 GbE iSCSI
  2. 25 GbE iSCSI
  3. 16 Gb FC
  4. 10 GbE iSCSI and 16 Gb FC

Answer(s): A

Explanation:

Dell Unity XT DPE (Disk Processor Enclosure) front-end port connectivity options that can support up to 45000 IOPS per port and up to 1500 MB/s include both 16 Gb Fibre Channel (FC) and 25 GbE iSCSI. These connectivity options provide the necessary performance and bandwidth to handle high IOPS and throughput demands:

16 Gb Fibre Channel (FC): Known for high performance and low latency, 16 Gb FC ports are widely used in enterprise storage environments to support high IOPS and bandwidth.

25 GbE iSCSI: 25 Gigabit Ethernet iSCSI ports offer high-speed connectivity for IP-based storage networks, capable of supporting high throughput and IOPS requirements.

Which describes cascade replication on the Dell Unity XT platform?

  1. Synchronous replication of a block resource from Sites A to B, then B to C, then C to D
  2. Synchronous replication of a file resource from Sites A to B, then B to C, then C to D
  3. Asynchronous replication of a file resource from Sites A to B, then B to C, then C to D
  4. Asynchronous replication of a block resource from Sites A to B, then B to C, then C to D

Answer(s): D

Explanation:

Cascade replication on the Dell Unity XT platform describes the process where a block resource is replicated asynchronously from one site to another in a sequential manner. Here's how it works:

Site A to Site B: The block resource is first replicated asynchronously from Site A to Site B.

Site B to Site C: After the replication from A to B is complete, the resource is then replicated from Site B to Site C.

Site C to Site D: Finally, the resource is replicated from Site C to Site D.

This cascade replication method allows for efficient data protection and disaster recovery across multiple sites.
