Nutanix SE Academy NCSE-Core Nutanix Study Notes

A. Data Locality:

The concept of data locality in Nutanix ensures that data is always kept close to the VM that uses it, typically on the same node. This reduces latency and provides high performance comparable to, or exceeding, traditional 16Gb Fibre Channel SAN solutions.

Data locality minimizes the need for data to travel over the network, effectively leveraging 10Gb Ethernet for low-latency and high-throughput operations, addressing the storage administrator’s concerns.

C. ABS (Acropolis Block Services):

Acropolis Block Services (ABS) enables Nutanix storage to be used by external servers, providing the performance and benefits of Nutanix’s distributed storage fabric while allowing the customer to continue using their existing investment in Oracle servers.

ABS allows the integration of all-flash storage with the existing Oracle environment, addressing the prospect's preference for all-flash arrays while leveraging Nutanix’s advanced storage capabilities.

Nutanix documentation on ABS describes its features and benefits, particularly its ability to integrate Nutanix storage with external servers and support high-performance applications like Oracle databases.

Relocating an AHV cluster to a new datacenter while maintaining the same IPs requires careful preparation to ensure minimal disruption and data integrity. The following steps are essential:

Stop all Nutanix Files clusters:

Nutanix Files clusters must be stopped to ensure that there are no ongoing file operations that could be disrupted during the relocation. This prevents data corruption and ensures a clean shutdown of file services.

Shut down all user VMs in the cluster:

Shutting down all user VMs ensures that there are no active workloads that could be interrupted. This step is crucial to prevent data loss and ensure a smooth transition when the cluster is powered up in the new datacenter.

Reconfigure IPMI and Relocate LDAP (Not Required):

Reconfiguring IPMI is not necessary if the IPMI interfaces are not affected by the physical relocation.

Relocating the linked LDAP server is also unnecessary unless the LDAP server itself is moving or changing its network configuration.

By following these steps, the administrator ensures that the cluster can be relocated safely with minimal risk of data loss or service interruption.
