Which I/O modules does the Unity 380/380F system support?

  1. 12 Gb/s SAS
    2-Port 100 GbE
  2. 32 Gb/s Fibre Channel 10 GbE Base-T
  3. 12 Gb/s SAS 10 GbE Base-T
  4. 32 Gb/s Fibre Channel 2-Port 100 GbE

Answer(s): C

Explanation:

The Unity 380/380F system supports two types of I/O modules: 12 Gb/s SAS back-end and 10 GbE Base-T front-end. The 12 Gb/s SAS back-end module provides connectivity to the disk drives and expansion enclosures, while the 10 GbE Base-T front-end module provides network connectivity to the hosts and clients. The Unity 380/380F system has four I/O module slots, two for each SP. The 12 Gb/s SAS back-end module must be installed in slot 0 of each SP, and the 10 GbE Base-T front-end module can be installed in slot 1 of each SP. Therefore, the correct answer is C. 12 Gb/s SAS 10 GbE Base-T.

Multiple I/O modules must be installed in Dell Unity XT 680 storage.
Which module must be installed in slot 0?

  1. 4-Port 25 Gbps Ethernet
  2. 4-Port 16 Gb Fibre Channel
  3. 4-Port 10 Gbps Ethernet
  4. 12 Gb/s SAS back-end

Answer(s): D

Explanation:

The Unity XT 680 system supports four types of I/O modules: 12 Gb/s SAS back-end, 4-Port 16 Gb Fibre Channel, 4-Port 25 Gbps Ethernet, and 4-Port 10 Gbps Ethernet. The 12 Gb/s SAS back-end module provides connectivity to the disk drives and expansion enclosures, while the other three types of modules provide network connectivity to the hosts and clients. The Unity XT 680 system has six I/O module slots, three for each SP. The 12 Gb/s SAS back-end module must be installed in slot 0 of each SP, and the other modules can be installed in slots 1 and 2 of each SP. Therefore, the correct answer is D. 12 Gb/s SAS back-end.

In an asynchronous replication, what is the maximum number of replicated NAS servers supported for the Dell Unity XT 380 series?

  1. 64
  2. 90
  3. 126
  4. 256

Answer(s): C

Explanation:

The maximum number of replicated NAS servers supported for the Dell Unity XT 380 series in an asynchronous replication is 126. This is the same as the maximum number of NAS servers supported for the Dell Unity XT 380 series in general. Asynchronous replication is a method of replicating data between two Dell Unity systems with a configurable recovery point objective (RPO). It allows the source system to continue normal operations without waiting for the destination system to acknowledge the completion of the replication.

What is a benefit of using vVols?

  1. They enable the automatic import of capability profiles from vSphere to Unisphere.
  2. All VMs on a datastore are snapped simultaneously.
  3. Individual VMs on a datastore can be snapped.
  4. They enable the assignment of isolated file storage partitions.

Answer(s): C

Explanation:

A benefit of using vVols is that individual VMs on a datastore can be snapped. vVols are virtual volumes that are stored on a storage array and managed by vSphere. They enable granular control and management of VM storage. With vVols, each VM has its own set of virtual disks that are mapped to corresponding storage objects on the array. This allows the array to perform snapshot operations on individual VMs without affecting other VMs on the same datastore.
