What function does the storsrvd daemon support?

  1. Manages Composite Groups and Device Groups
  2. Provides centralized gatekeeper device management
  3. Provides replication consistency protection
  4. Listens for SYMAPI sessions and management requests

Answer(s): D

Explanation:

The storsrvd daemon is a critical component of the Solutions Enabler (SYMCLI) software suite used to manage Dell PowerMax and VMAX storage arrays. Its primary function is to:

Listen for SYMAPI Sessions: It acts as a communication endpoint, listening for incoming SYMAPI sessions from clients or management tools like Unisphere.

Handle Management Requests: When a client connects, storsrvd receives and processes SYMAPI commands and requests, forwarding them to the appropriate components within Solutions Enabler for execution.

Essentially, storsrvd acts as an intermediary between SYMCLI clients and the storage array, facilitating communication and management operations.

Why other options are incorrect:

A . Manages Composite Groups and Device Groups: This is handled by other components within Solutions Enabler.

B . Provides centralized gatekeeper device management: While storsrvd plays a role in device management, it's not the sole component responsible for it.

C . Provides replication consistency protection: This is a function of SRDF (Symmetrix Remote Data Facility) and related components.

An administrator is using the Workload Planner feature in Unisphere for PowerMax

How does the Planner calculate if the Storage Group workload is stable?

  1. One of the calculated values is within 10-20% of the SL-defined response time
  2. Both calculated values are within a 10-15% threshold of the SL-defined response time
  3. One of the calculated values remains within the SL-defined response time
  4. Both calculated values are within the SL-defined response time.

Answer(s): D

Explanation:

Step by Step Comprehensive Detailed

The Workload Planner in Unisphere for PowerMax helps you analyze and predict the performance impact of adding new workloads to your storage array. It uses sophisticated algorithms to calculate how the addition of a new workload will affect the existing workloads and whether it will violate any service level objectives (SLOs).

To determine if a Storage Group workload is stable, the Planner considers two key calculated values:

Read Response Time: The predicted read response time of the Storage Group after the new workload is added.

Write Response Time: The predicted write response time of the Storage Group after the new workload is added.

The Planner compares these calculated values against the service level (SL) defined for the Storage Group. If both the calculated read and write response times fall within the defined SL response time, the Planner considers the workload to be stable. This means that the new workload can be added without negatively impacting the performance of the existing workloads or violating the SLOs.

Why other options are incorrect:

A . One of the calculated values is within 10-20% of the SL-defined response time: Both read and write response times must be within the defined SL, not just one.

B . Both calculated values are within a 10-15% threshold of the SL-defined response time: The threshold is not fixed at 10-15%. The calculated values must be within the actual SL-defined response time.

C . One of the calculated values remains within the SL-defined response time: Again, both read and write response times need to be within the defined SL.

When using TimeFinder SnapVX technology, what is the maximum number of target volumes that can be linked to a snapshot on a single source volume?

  1. 255
  2. 256
  3. 512
  4. 1024

Answer(s): A

Explanation:

Step by Step Comprehensive Detailed

TimeFinder SnapVX is a snapshot technology in PowerMax that allows you to create point-in-time copies of data.
When using SnapVX, you can link target volumes to a snapshot to create writable copies of the data at that specific point in time.

The maximum number of target volumes that can be linked to a single snapshot on a source volume is 255. This limitation ensures efficient management and performance of the SnapVX snapshots and linked targets.

Why other options are incorrect:

B . 256, C. 512, D. 1024: These numbers exceed the maximum limit of linked targets per snapshot.

Which tasks can a storage administrator manage from the Data Protection menu in the Unisphere for PowerMax?

  1. Convert front-end ports to SRDF ports
  2. Configure and manage SRDF groups
  3. Configure Data Protection for z systems
  4. Review the audit log for unwanted logins

Answer(s): B

Explanation:

Step by Step Comprehensive Detailed

The "Data Protection" menu in Unisphere for PowerMax provides a centralized location for managing various data protection features and functionalities. Specifically, it allows storage administrators to:

Configure and manage SRDF groups: SRDF (Symmetrix Remote Data Facility) is a key technology for disaster recovery and data replication in PowerMax. The Data Protection menu enables administrators to create, modify, and monitor SRDF groups, establish replication relationships between devices, and control replication settings.

Why other options are incorrect:

A . Convert front-end ports to SRDF ports: This is typically done through the "System > Hardware" or "Connectivity" sections of Unisphere, where port configurations are managed.

C . Configure Data Protection for z Systems: While PowerMax supports mainframe environments, the specific configuration for z Systems might involve specialized tools or interfaces.

D . Review the audit log for unwanted logins: Audit logs and security-related events are usually found in the "Monitoring" or "Security" sections of Unisphere.
