Data Protection Strategy The below image is a representation of the capabilities that the Nutanix solution offers across the entire data protection spectrum. Nutanix offers a natively integrated solution for data protection and continuous availability at VM granularity. It gives administrators an affordable range of options to meet the recovery point objectives (RPO) and recovery…
Synchronous Replication is a feature where data is synchronously replicated between two sites in metro availability configuration. In an event of a disaster on any one site, real-time data is available on the other site. The protection domain can be configured for metro availability or for synchronous replication depending on the following: Metro availability: The…
After completing the NCP, the NCAP was the next goal on my list. I began to prepare for this in a similar fashion to how I did with the NCP. The first step was of course, to download the Exam Blueprint. As with the NCP guide, a big credit again goes to Steven Poitras, and…
You configure a protection domain by using Async DR feature (up to 1-hour RPO) or NearSync DR (up to 1-minute RPO ) by defining a group of entities (VMs and volume groups) that are backed up locally on a cluster and optionally replicated to one or more remote sites. See the DR best practices guide from https://portal.nutanix.com/#/page/solutions for guidance…
A remote site is the target location to store data replications for protected domains. The remote site can be either another physical cluster or a cluster located in a public cloud. To configure a remote physical cluster that can be used as a replication target, do the following: Network and vStore Mappings are used to…
After a protection domain is replicated to at least one remote site, you can carry out a planned migration of the contained entities by failing over the protection domain. You can also trigger failover in the event of a site disaster. Failover and failback events re-create the VMs and volume groups at the other site,…
NearSync Building upon the traditional asynchronous (async) replication capabilities mentioned previously; Nutanix has introduced support for near synchronous replication (NearSync). NearSync provides the best of both worlds: zero impact to primary I/O latency (like async replication) in addition to a very low RPO (like sync replication (metro)). This allows users have a very low RPO…
I have always been a fan of leveraging community resources when studying for certification exams. The VCAP study guides here, and here were invaluable when I was studying for those exams. When I began preparing for the Nutanix NCP, I was a little bummed out when I couldn’t find any community resources like these. I…
