[All D-XTR-OE-A-24 Questions]

Which non-optimal configuration may have a significant effect on write operations on a Linux server connected to XtremIO?

Show Suggested Answer Hide Answer
Suggested Answer: D

To provision XtremIO volumes to servers, the following steps are typically required:

Host Configuration: This involves setting up the host with the necessary drivers and tools to communicate with the XtremIO storage system. It may include installing HBA drivers, multipathing software, and configuring host parameters to optimize performance1.

SAN Connectivity: Establishing SAN connectivity is crucial for the host to access the XtremIO volumes. This step involves zoning in the SAN switches to ensure that the host can see the XtremIO storage controllers1.

Initiator Group: An initiator group is a collection of host initiators (WWNs or IQNs) that are allowed to access a set of volumes. Creating and configuring an initiator group in the XtremIO system is necessary to control access to the volumes1.

Volumes Mapping: The final step is to map the volumes to the host. This is done by associating the volumes with the initiator group that contains the host's initiators. Once mapped, the volumes will be accessible to the host for data storage and retrieval1.

The other options, such as RAID groups (OA), creating pools (OB), and encryption (OC), are not directly related to the provisioning process of XtremIO volumes to servers. RAID groups and pools are typically managed within the storage system itself, while encryption is a data security feature that may be configured as part of the overall storage setup1.

Misaligned data? What is this, a poetry contest? I just want to know how to make my server go faster, not write a sonnet!

I'm no storage expert, but I'm pretty sure the right answer is Option D. 16k just seems like a nice, round number that could cause some trouble.

I think you might be onto something with Option D. It does sound like it could cause some trouble.

Ha, misaligned data to the 8k boundaries? What is this, Windows? Linux is all about the 4k these days!

I'm leaning towards option C, 32k. That's a common file system block size, and I bet it could really mess things up on an XtremIO system.

Hmm, I think it's got to be misaligned data to the 4k boundaries. That's the standard block size for Linux, right?

User 2: Yeah, that's the standard block size for Linux, so it makes sense.

I believe misaligned data to the 32k boundaries could also have a significant impact on write operations. It's important to align data properly for optimal performance.

I agree with Erin. Misaligned data to the 4k boundaries can cause performance issues on the Linux server connected to XtremIO.
