About the R0Q21A

R0Q21A is the genuine HPE 4-pack of 10Gb Short Range iSCSI SFP+ optical transceivers for 6th generation Modular Smart Array (MSA) storage systems. Enabling high-throughput IP SAN connectivity at 10 Gb/s, they provide reliable network connectivity between MSA storage arrays and enterprise Ethernet switches.

Compatibility

Compatible exclusively with 6th generation HPE MSA storage systems, including HPE MSA 1060, MSA 2060, and MSA 2062 arrays configured with 10GbE iSCSI host controller canisters. Plugs into controller SFP+ host ports for direct switch or server host attachment.

How to identify a genuine unit

Standard SFP+ 10GbE optical transceiver with zinc die-cast metal housing, blue/beige extraction latch, and duplex LC optical connector receptacle. Product label displays option part number R0Q21A, spare part number R3B11A, and assembly part number P10315-001.

Buying used

Inspect optical transceiver ferrule receptors for signs of debris or damage. Confirm that the latch mechanism secures the transceiver in the cage. Verify via MSA SMU that the link establishes at 10 Gb/s Full Duplex with zero frame drops or CRC errors.

Works together

How the HPE R0Q21A connects to servers, storage and the network: 3 ways, with the hardware on each path.

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.

File storage (NFS and SMB): how it fits together

Hyperconverged cluster

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