When designing an Intelligent Resilient Framework (IRF) stack for a Nimble storage solution using HPE FlexFabric 5900CP switches with iSCSI connectivity, the IRF stack typically supports up to two switches for optimal performance and redundancy. This limitation ensures that the iSCSI traffic is managed effectively without overcomplicating the network topology, which could potentially introduce latency or complexity in managing the stack.

Utilizing more than two switches in an IRF stack when connecting to storage could result in diminished returns in performance or increased management overhead, which is why HPE typically recommends limiting the IRF stack to two switches in such configurations.

For optimizing an iSCSI-based storage system, especially in environments handling large data volumes such as video streaming, enabling jumbo frames is recommended. Jumbo frames allow the transmission of larger data packets over the network, reducing the overhead caused by smaller packets and improving overall network efficiency. This is particularly important in video streaming, where continuous, high-bandwidth data transfer is required. Enabling jumbo frames across all components, including switches, network interface cards (NICs), and storage devices, can significantly improve performance.

HPE SPOCK (Single Point of Connectivity Knowledge) is the authoritative source for information on supported configurations, firmware levels, drivers, and operating systems for HPE storage products. It provides detailed compatibility matrices and reference documents for ensuring that all components in the HPE storage environment, including storage arrays, SAN switches, servers, and operating systems, are compatible and supported.

SPOCK is regularly updated with the latest information, making it an essential tool for planning upgrades and ensuring a stable, supported configuration in HPE storage environments.
