D-MSS-DS-23 Practice Test

Explanation:

When connecting Disk Array Enclosures (DAEs) to SAS ports on a Dell Unity XT DPE (Disk Processor Enclosure) with only two ports available on each SP (Storage Processor), the recommended order is DAE 1 to SAS Bus 0, DAE 2 to SAS Bus 1, and DAE 3 to SAS Bus 0. This configuration helps in balancing the load across the available SAS ports, ensuring optimal data flow and performance. Reference:Dell Unity XT Configuration Guide

Explanation:

SAS Flash 2 drives can be used in a FAST Cache pool configuration for Dell Unity XT solutions. FAST Cache (Fully Automated Storage Tiering Cache) allows frequently accessed data to be moved to high-performance SSDs, improving overall system performance. SAS Flash 2 drives are suitable for this purpose, providing a balance of performance, endurance, and cost. Reference:Dell Unity XT FAST Cache Overview

Explanation:

The "Quick Configuration" sizer option supports the configuration of a midrange solution with hybrid dynamic pools. This option allows for a streamlined setup process, making it easier to configure storage pools that combine both SSDs and HDDs for optimized performance and capacity.

Explanation:

Dell PowerStore supports media devices that carry a FIPS Type D certification to ensure data security and compliance with Federal Information Processing Standards (FIPS). The certified media devices include:

SAS SSD:Serial Attached SCSI (SAS) Solid State Drives are commonly used in enterprise storage solutions for their reliability and performance.

NVMe SSD:Non-Volatile Memory Express (NVMe) Solid State Drives offer high-speed storage access and are optimized for performance.

NVMe SCM:NVMe Storage Class Memory provides a new tier of storage that bridges the gap between DRAM and traditional SSDs, offering both speed and persistence.

NVRAM:Non-Volatile Random Access Memory combines the speed of RAM with the persistence of flash storage, ensuring data is retained even after power loss.

These devices are FIPS Type D certified, ensuring they meet stringent security standards for data protection.
