About the C8R23A

C8R23A is the official HPE 4-pack of 10Gb Short Range iSCSI SFP+ optical transceivers designed for Modular Smart Array (MSA) storage systems. Enabling cost-effective IP SAN block storage networking at 10 Gb/s, they provide low-latency host connectivity to virtualized hypervisors over multimode fiber infrastructure.

Compatibility

Compatible with all HPE Modular Smart Array (MSA) storage controllers equipped with SFP+ host interface ports configured for iSCSI operation, including HPE MSA 1040, MSA 2040, MSA 1050, MSA 2050, and MSA 2052 SAN storage arrays. Plugs directly into controller SFP+ host interface slots.

How to identify a genuine unit

SFP+ optical transceiver module featuring a ruggedized metallic housing, beige extraction bail clasp, and standard duplex LC connector optical receptacle. Printed label clearly displays option part number C8R23A, spare part number 733803-001, and assembly part number 720998-001.

Buying used

Inspect optical bores for dirt, dust particles, or scratching on internal optical components. Verify that the transceiver clasp locks firmly into the controller SFP+ slot. Confirm via MSA SMU that optical power levels register within normal operational thresholds.

Works together

How the HPE C8R23A connects to servers, storage and the network: 3 ways, with the hardware 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.

Storage

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.

FAQ

Can C8R23A transceivers be mixed with 16Gb FC transceivers in the same MSA controller?

Yes, on Converged SAN Controllers (such as MSA 2050 SAN), each port pair can be configured independently for 16Gb FC or 10Gb iSCSI mode.

What cable type is required for C8R23A?

Multimode optical fiber patch cables with duplex LC connectors (OM3 or OM4) are required.
