QUESTION 53
Which tool must a Solution Architect use to check compatibility of a new storage solution with an existing infrastructure?

Live Optics

E-Lab Navigator

Atlas

DTM Assist

The tool that a Solution Architect must use to check the compatibility of a new storage solution with an existing infrastructure is E-Lab Navigator. E-Lab Navigator is a comprehensive online database provided by Dell that includes compatibility information for various hardware and software configurations. It helps ensure that new storage solutions are compatible with existing infrastructure, reducing the risk of integration issues.

QUESTION 54
What is the minimum number of drives in a RAID 6 dynamic pool?

QUESTION 55
A systems administrator has deployed a Dell Unity XT 380F system with 15x 1.92 TB SSD drives, in a RAID 5 dynamic pool. Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density. What will happen if the administrator adds 4x 3.84 TB SSD drives?

The full capacity of the drives will be available.

Only half of the capacity of the new drives will be available.

Three of the drives will be added with a fourth reserved as spare.

The mixing of drive types is not supported, and the operation will fail.

When the administrator adds 4x 3.84 TB SSD drives to a RAID 5 dynamic pool in a Dell Unity XT
380F system, the full capacity of the new drives will be available. Dell Unity XT systems support mixing different drive sizes within a dynamic pool, allowing administrators to expand the storage capacity seamlessly.

The failover process is automatic and transparent to the hosts accessing the data, and it helps to maintain the high availability of the NAS services.

QUESTION 62
How many writes per day are SAS Flash 3 drives rated at?

SAS Flash 3 drives(also known asRead-Intensive (RI)SSDs in Dell Unity XT environments) are typically rated at3 Drive Writes Per Day (DWPD).
#What does 3 DWPD mean?
It means that these drives are designed to safely handle writingthree times their entire capacity every dayover their warranty period (usually 5 years).
For example, a 1TB SAS Flash 3 drive can handle up to3TB of writes per daywithout exceeding its endurance specification.
#Why is this important?
The DWPD metric is a crucial factor in determining whether a drive’s endurance matches the expected workload.
3 DWPDstrikes a balance betweenenduranceandcostin most general-purpose storage workloads.
#Where is this documented?
TheDell EMC Unity XT Best Practices Guideand theDell EMC Unity XT Drive Specification Guidedetail the DWPD ratings for different flash drive types, including SAS Flash 3 drives.
