What is the recommended order for connecting DAEs to SAS ports when only two ports are available on each SP of a Dell Unity XT DPE?
- A. DAE 1 to SAS Bus 1 DAE 2 to SAS Bus 0 DAE 3 to SAS Bus 1
- B. DAE 1 to SAS Bus 0 DAE 2 to SAS Bus 0 DAE 3 to SAS Bus 1
- C. DAE 1 to SAS Bus 0 DAE 2 to SAS Bus 1 DAE 3 to SAS Bus 0
- D. DAE 1 to SAS Bus 1 DAE 2 to SAS Bus 1 DAE 3 to SAS Bus 0
Answer: C
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

NEW QUESTION # 54
A company has a Dell Unity XT 880 at its Boston site providing file storage for a business production application. The company has a second remote site 8 km (5 mi) away in Cambridge. A third site is in New York (342 km (213 mi) from the Boston site). How can the same production data be protected against system outage with a zero RPO and a maximum of 15 minutes RPO data recovery?
- A. Synchronous replicate from Boston to Cambridge Synchronous replicate from Cambridge to New York
- B. Synchronous replicate from Boston to Cambridge Synchronous replicate from Boston to New York
- C. Synchronous replicate from Boston to Cambridge Asynchronous replicate from Boston to New York
- D. Asynchronous replicate from Boston to Cambridge Asynchronous replicate from Cambridge to New York
Answer: C
Explanation:
Dell Unity XT offers both synchronous and asynchronous replication to protect data and ensure business continuity.
Synchronous replication is used for zero RPO, ensuring no data loss, but it is typically limited to shorter distances due to latency concerns.
Asynchronous replication is suitable for longer distances and provides near real-time data protection with a minimal RPO.
Distance Considerations:
The distance between Boston and Cambridge (8 km) is suitable for synchronous replication, providing zero RPO.
The distance between Boston and New York (342 km) is better suited for asynchronous replication due to latency, ensuring data recovery with a minimal RPO, such as 15 minutes.
Optimal Replication Strategy:
Synchronous replication from Boston to Cambridge ensures zero RPO for critical data protection.
Asynchronous replication from Boston to New York provides additional data protection with a 15-minute RPO, suitable for longer-distance disaster recovery.
Dell Midrange Storage References:
Dell Unity XT documentation and best practices provide detailed guidelines on configuring synchronous and asynchronous replication.
Community forums and support resources from Dell Technologies offer insights into real-world implementation strategies.

NEW QUESTION # 58
What is the maximum RPO that can be configured on a Dell Unity XT block-asynchronous replication session?
- A. 48 hours
- B. 24 hours
- C. 14 days
- D. 7 days
Answer: D
Explanation:
Asynchronous Replication in Dell Unity XT:
Asynchronous replication provides data protection over longer distances with flexible RPO settings.
Maximum RPO:
The maximum Recovery Point Objective (RPO) that can be configured for a block-asynchronous replication session in Dell Unity XT is 7 days.
This allows for up to a week's worth of data to be replicated asynchronously, balancing data protection and replication overhead.
Other Options:
24 hours, 48 hours, 14 days: These options do not align with the maximum configurable RPO of 7 days for asynchronous replication in Dell Unity XT.
