Which data savings technique utilizes stripes and parity calculation in a Nutanix cluster?

Show Suggested Answer Hide Answer
Suggested Answer: C

According to the Nutanix Support & Insights web search result1, erasure coding is a data savings technique that utilizes stripes and parity calculation in a Nutanix cluster. Erasure coding increases the usable capacity on a cluster by reducing the replication factor of data blocks. Instead of replicating data, erasure coding uses parity information to rebuild data in the event of a disk or node failure.Erasure coding can save up to 50% of storage space compared to replication factor 2, and up to 75% compared to replication factor 32.

Erasure coding? Really? That sounds complicated!

Wait, are you sure it's not Deduplication?

Compression doesn't use parity, so that's out.

Compression and deduplication don't really use parity, so I guess that leaves us with either C or B, but I'm leaning towards C.

I practiced a similar question last week, and I believe it was about erasure coding too. It seems to fit the description best.

I remember studying about different data protection techniques, and I feel like parity strip was mentioned, but it doesn't sound quite right for this question.

I think the answer might be C, Erasure coding, since it involves both stripes and parity, but I'm not entirely sure.

I've got this! Erasure coding is the data savings technique used in Nutanix clusters. It stripes data across multiple nodes and calculates parity to provide redundancy. That matches the details given in the question.

Okay, let me see. Compression and deduplication are more general data savings techniques, not specific to Nutanix. Parity strips and erasure coding both use redundancy, so I'm leaning towards one of those as the answer. I'll review my notes on Nutanix to try to figure out the difference.

Hmm, I'm a bit unsure about this one. Parity strips and erasure coding both involve some kind of redundancy, but I'm not totally clear on the differences. I'll have to think this through carefully.

I'm pretty sure this is asking about erasure coding, which uses parity calculations to provide data redundancy. That seems like the most relevant technique for a Nutanix cluster.

I'm a little confused by this question. I'll need to review my notes on network security to make sure I understand the potential issues with a BYOD exam setup.

C) Erasure coding, no doubt! I can already hear the Nutanix marketing team high-fiving each other over this one. It's like the duct tape of data storage.
