Helping Hand Questions for NCSE-Core

C. ABS (Acropolis Block Services):

Nutanix ABS (Acropolis Block Services) provides the ability to use Nutanix storage with external servers while leveraging the benefits of Nutanix’s distributed storage fabric.

This feature is particularly beneficial for Oracle environments where the organization has invested significantly in servers to save on licensing costs. ABS allows these existing servers to utilize Nutanix's all-flash storage without moving workloads entirely onto Nutanix nodes.

ABS can provide high performance and low latency storage which is critical for Oracle databases and helps address the customer's preference for all-flash arrays.

B. Review budgetary pricing:

The Sizer BOM (Bill of Materials) provides a breakdown of the components and their costs, allowing the SE to review budgetary pricing and ensure the solution fits within the prospect’s financial constraints.

C. Review workload sizing details:

The Sizer BOM includes detailed workload sizing information, which helps the SE verify that the proposed solution meets the performance and capacity requirements for the SQL Server workload running on Cisco C240 M4 servers.

Nutanix Sizer tool documentation explains how to use the BOM for reviewing pricing and workload sizing details.

For highly active SQL workloads that write I/Os in 2 MB chunks to a vDisk, compression is the most suitable storage optimization technology. Compression works well with larger I/O sizes and can significantly reduce the storage footprint, providing better capacity optimization. This approach ensures that the large chunks of data are compressed efficiently, maximizing storage utilization and performance​​.

A. Data Locality:

Nutanix's data locality feature ensures that data is kept close to the VM that uses it, typically on the same node. This reduces latency and improves performance by minimizing the need for data to travel over the network.

This feature is crucial in a hybrid configuration as it ensures that frequently accessed data remains on the faster SSD tier, thus enhancing overall performance.

E. Automatic Data Tiering:

Nutanix employs automatic data tiering to move data between different types of storage (e.g., SSD and HDD) based on usage patterns. Frequently accessed data is kept on faster SSDs, while less frequently accessed data is moved to HDDs.

This ensures optimal performance by leveraging the speed of SSDs for active data while utilizing the capacity of HDDs for less critical data, thereby addressing the storage administrator's concerns about performance in a hybrid setup.

The Nutanix Bible and other technical documentation explain these features in detail, emphasizing how they contribute to high performance and efficient storage management in Nutanix clusters.
