How many 10GbE access ports does the HPE JH390A provide?

The HPE FlexFabric 5940 48SFP+ 6QSFP28 Switch JH390A provides 48 SFP+ interfaces, designed for 10GbE connectivity. This allows you to connect up to 48 10GbE servers or network devices per switch using SFP+ optics or direct attach cables, which is useful for dense top of rack deployments.

What uplink options are available on the HPE FlexFabric 5940 JH390A?

The switch includes 6 QSFP28 uplink interfaces. These QSFP28 ports are intended for high‑bandwidth inter‑switch links, for example to aggregation or core switches. This uplink capacity helps ensure that traffic from the 48 SFP+ 10GbE access ports can be carried efficiently into the rest of the data center network.

Is the HPE JH390A suitable for Layer 3 routed environments?

Yes, the HPE FlexFabric 5940 48SFP+ 6QSFP28 JH390A is classified as a Layer 3 managed switch. This means it is designed for deployments that require routing and segmentation between different network segments, making it suitable for data center environments where Layer 3 functionality at the access or aggregation layer is needed.

What type of environments is the HPE FlexFabric 5940 JH390A designed for?

This switch is positioned as a data center level device. With 48 SFP+ 10GbE access ports and 6 QSFP28 uplinks, along with Layer 3 managed capabilities, it is intended for roles such as top of rack or server access, and can also support aggregation in structured data center network designs.

Can the HPE JH390A be used where 10GbE is the standard access speed?

Yes, the HPE FlexFabric 5940 48SFP+ 6QSFP28 JH390A is well aligned with 10GbE access environments. Its 48 SFP+ ports are designed for 10GbE connectivity, allowing you to standardize server and device connections on 10GbE while using the 6 QSFP28 uplinks to connect into higher tiers of the network.
