When configuring disk groups for Oracle ASM using XtremlO as the storage array, what is the recommended redundancy type for the ASM disk groups?

Show Suggested Answer Hide Answer
Suggested Answer: C

When using XtremIO storage arrays for Oracle ASM disk groups, the recommended redundancy type is typically external redundancy. This is because XtremIO arrays are built with inherent data protection and redundancy features that eliminate the need for additional mirroring at the ASM level1.

External Redundancy: With external redundancy, Oracle ASM does not mirror data within the disk group. Instead, it relies on the underlying storage system to provide redundancy and data protection. XtremIO's unique data protection scheme, XDP (XtremIO Data Protection), provides such redundancy1.

XtremIO Features: XtremIO arrays are designed with high levels of fault tolerance and include features like SSD failover and advanced error correction. These features ensure data integrity and availability, making external redundancy a suitable choice1.

Performance Considerations: Choosing external redundancy can also lead to better performance since it avoids the overhead of additional mirroring at the ASM level, which is unnecessary given XtremIO's capabilities1.

Best Practices: Dell EMC recommends using external redundancy for ASM disk groups when using storage arrays like XtremIO that provide their own robust data protection mechanisms1.

In summary, for Oracle ASM disk groups using XtremIO storage arrays, external redundancy (OC) is the recommended setting, as it leverages the array's built-in redundancy features and optimizes performance1.

D) Normal is the correct answer. It's the standard redundancy type for ASM with XtremIO, no need to get fancy.

I practiced a similar question, and I think "High" redundancy is the safest option for critical data, but I might be mixing it up with another topic.

I believe "External" redundancy is typically used when integrating with certain storage solutions, but I’m not confident if it applies here.

I'm confident the answer is C) External. ASM doesn't need to manage the redundancy when using an external storage array like XtremlO, so that's the recommended option.

I remember learning about the different ASM redundancy types, but I'm drawing a blank on which one is best for XtremlO. I'll have to review my notes before answering this one.

Okay, let me see. XtremlO is an external storage array, so the redundancy would need to be handled at that level, not within ASM. I'm pretty sure the answer is External.
