Adaptive Flash Cache (AFC) is a feature in HPE 3PAR StoreServ arrays that improves performance for random reads by using flash storage as an extended cache. This feature is especially beneficial for workloads with high random read activity, as it accelerates read operations by storing frequently accessed data in the flash cache, reducing latency and improving overall performance.

HPE Storage Performance Features

When using HPE InfoSight with VMVision to analyze end-to-end latency in a VMware vSphere environment connected to HPE storage solutions, the following components are displayed:

iSCSI network (SAN): InfoSight with VMVision provides insights into the performance of the storage area network (SAN) layer, specifically the iSCSI connections that are used for data transfer between the storage array and the compute infrastructure.

Storage: The storage component of the stack, which includes the HPE Nimble HF-series array, is monitored for performance metrics such as latency, throughput, and IOPS. InfoSight analyzes these metrics to identify potential bottlenecks and optimize storage performance.

Host: The host component refers to the VMware vSphere hosts running on the HPE Synergy frames. InfoSight provides detailed visibility into the performance of these hosts, including CPU, memory, and I/O operations, helping administrators to identify and resolve performance issues at the host level.

These components are critical for comprehensive performance management and troubleshooting, ensuring optimal operation of the entire solution stack.

HPE Nimble Storage with InfoSight

For a customer needing a centralized storage solution accessible by Windows-based laptops and other personal devices, file-oriented storage accessed over SMB (Option D) is the most appropriate recommendation. SMB (Server Message Block) is a network file sharing protocol that allows files to be shared among devices running on a Windows network.

File-oriented storage solutions, like HPE's StoreEasy or Nimble with file services, are designed to serve files over the network using SMB, providing easy and secure access to departmental data.
