D-ISM-FN-01 Exam Dumps : Dell Information Storage and Management Foundations v2 Exam

Astorage nodeis a component in a backup architecture that handles the actualdata movementduring the backup process:

Itorganizesthe backup data stream.

Itwritesthe data to the backup target (disk, tape, or cloud).

It does not manage policies or schedules (that’s the role of the backup server or management console).

Option A:Monitoring is done by the backup server or management tools.

Option C:Backup management (scheduling, policies) is also handled by the backup server.

Option D:Deduplication may be part of the process but is not theprimary roleof a storage node.

Storage Class Memory (SCM) bridges the gap between DRAM and NAND flash memory. It offers faster access times than flash memory but is still slower than DRAM. SCM provides non-volatile storage with performance characteristics closer to DRAM, making it suitable for applications requiring high-speed data access.

Storage Class Memory (SCM) represents a new class of storage technology that bridges the gap between traditional DRAM and NAND flash memory. SCM offers significantly lower latency and higher endurance compared to NAND flash, making it the highest-performing storage medium currently available. Due to its advanced technology and performance characteristics, SCM is also the most expensive among the listed options.

FC (Fibre Channel):A network protocol used for high-speed data transfer, not a type of disk device.

SATA (Serial ATA):Commonly used in consumer-grade storage; offers lower performance and cost.

SAS (Serial Attached SCSI):Offers better performance than SATA but still lags behind SSDs and SCM.

SSD (Solid State Drive):Provides faster data access than HDDs but is outperformed by SCM.

SCM (Storage Class Memory):Combines the speed of DRAM with the persistence of NAND, offering unparalleled performance.
