NEW QUESTION # 21
A company's storage administration team wants to receive e-mail notifications when the XtremlO cluster detects an issue of major severity. The administration team hassuccessfully configured and tested the e-mail server in the XtremlO web interface. However, the e-mail server is not receiving the expected notifications when major severityissues appear.
What is the cause of this issue?

  • A. Private reports have not been defined
  • B. Event handlers have not been defined
  • C. Alert definitions have not been defined
  • D. ESRS must also be configured

Answer: C

Explanation:
* If the email server is not receiving notifications for major severity issues, it is likely because alert definitions have not been defined.
* Alert definitions specify the conditions under which notifications are sent, and without these, the system will not trigger email alerts.
* Ensuring proper configuration of alert definitions is essential for timely notifications of critical events.

NEW QUESTION # 22
In a heterogeneous environment, what is a recommended setting when multiple storage arrays are connected to VMware vSphere in addition to XtremIO X2?

  • A. Disk.SchedNumReqOustanding = 32
  • B. Disk.SchedQuantum = 64
  • C. fnic_max_qdepth = 128
  • D. XCOPY = 256

Answer: B

Explanation:
* In a heterogeneous environment with multiple storage arrays connected to VMware vSphere, setting Disk.SchedQuantum to 64 is recommended.
* This setting optimizes the scheduling of I/O requests and helps in balancing the load across different storage arrays.
* Proper configuration of Disk.SchedQuantum enhances the performance and efficiency of the storage environment.

NEW QUESTION # 23
In addition to HBA driver configuration, file system queue depth, and data alignment, what other host configuration should be verified when connecting new hosts to XtremIO arrays?

  • A. SSD bandwidth
  • B. Snapshot size
  • C. Path bandwidth
  • D. Volume size

Answer: C

Explanation:
When connecting new hosts to XtremIO arrays, it is essential to verify the path bandwidth in addition to HBA driver configuration, file system queue depth, and data alignment. Path bandwidth refers to the capacity of the data paths between the host and the storage array, which can significantly impact overall performance.
* Path Bandwidth: This is the amount of data that can be transferred between the host and the storage array within a certain time frame.Ensuring that the path bandwidth is sufficient is crucial for maintaining
* high performance and avoiding bottlenecks in data transfer1.
* HBA Driver Configuration: The Host Bus Adapter (HBA) drivers must be correctly configured to support the connection to the XtremIO array.This includes setting the appropriate parameters and ensuring that the latest drivers are installed1.
* File System Queue Depth: This setting determines how many I/O operations can be queued at the file system level.It should be optimized based on the storage array's capabilities and the expected workload1.
* Data Alignment: Proper data alignment is necessary to ensure efficient access to the storage array.Misalignment can lead to performance degradation and increased latency1.
* Volume Size (OA): While volume size is an important consideration, it is not typically a host configuration setting that needs to be verified for connectivity purposes.
* SSD Bandwidth (OB): SSD bandwidth is more related to the storage array's internal performance rather than a host configuration setting.
* Snapshot Size (OC): The size of snapshots is managed within the storage array and does not directly impact host configuration for connectivity.


NEW QUESTION # 24
Which key components within XtremlO X1 provide an enterprise level of continuous availability?

  • A. Data Protection and Snapshots
  • B. Thin Provisioning and Snapshots
  • C. Inline Data Deduplication and Inline Compression
  • D. Thin Provisioning and Data Protection

Answer: A

Explanation:
XtremIO X1 provides continuous availability through a combination of data protection mechanisms and snapshot capabilities:
* Data Protection: XtremIO X1 uses a unique data protection scheme known as XtremIO Data Protection (XDP), which offers better efficiency and rebuild performance compared to traditional RAID configurations.XDP provides high levels of fault tolerance and ensures data integrity, which is essential for continuous availability1.
* Snapshots: XtremIO's snapshot technology allows for the creation of instant, space-efficient copies of data volumes.These snapshots can be used for various purposes, including backup and recovery, testing, and development, without impacting the performance of the primary system1.
* Continuous Availability: The combination of XDP and snapshots enables XtremIO X1 to provide an enterprise level of continuous availability by ensuring that data is protectedagainst hardware failures and that operations can continue uninterrupted during maintenance or in the event of a disaster1.
XtremIO's approach to data protection and snapshots is designed to meet the demands of enterprise environments where downtime is not an option, and data must be accessible at all times1.
