The HPE Aruba CX 8325-48Y8C is a high-density 1U top-of-rack data center and storage switch running ArubaOS-CX. Engineered for 25GbE server access and 100GbE spine connectivity, it delivers 6.4 Tbps of line-rate throughput with high-capacity packet buffering to prevent frame drops in iSCSI, RoCE v2, and hyperconverged storage traffic. ArubaOS-CX provides cloud-native modularity with full REST APIs, the Aruba Network Analytics Engine (NAE) for on-switch telemetry, and VSX active-active redundancy. When evaluating used units, check fan tray airflow direction part numbers (port-to-power JL624A vs power-to-port JL625A) and test optical link establishment.

Works together

How the HPE Aruba CX 8325-48Y8C connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.

Buying a used CX 8325-48Y8C: what to check

Verify SKU part number for correct airflow direction: JL624A indicates port-to-power (front-to-back) and JL625A indicates power-to-port (back-to-front). Inspect NAE database functionality and reset console admin login.

FAQ

Can 100G QSFP28 ports be broken out into 4x 25G or 4x 10G?

Yes, each 100G port supports optical or copper DAC breakout cables into four 25GbE or 10GbE connections.

Does the 8325 support lossless storage networking?

Yes, it implements RoCEv2 with Priority-based Flow Control (PFC) and Explicit Congestion Notification (ECN) for storage fabrics.

What network operating system powers the Aruba CX 8325?

It runs ArubaOS-CX, a microservices-based operating system featuring real-time state database synchronization and integrated Python scripting.

Can the 100GbE QSFP28 ports be used for breakout connections?

Yes, each 100GbE QSFP28 port can be broken out into four 25GbE or four 10GbE links using supported DAC or optical splitter cables.
