HPE B-Series SAN Switches - Refurbished, Used, New

Best Selling

HPE B-Series SAN switches are 1U Fibre Channel switches that connect servers to storage arrays. This collection carries the SN3000B, SN3600B and SN6600B in new, refurbished and used condition, along with the SN3000B power supply and fan assembly and the AJ716B 8Gb shortwave SFP+ transceiver. Refurbished and used units are tested before they ship.

Which HPE B-Series switch do I need?

The choice comes down to speed, port count and power redundancy. The SN3000B is a 16Gb switch with 24 ports, 12 of them active on the QW937B. The SN3600B runs at up to 32Gb per port and has 24 ports, sold with either 8 or 24 active. The SN6600B is also 32Gb, with 48 SFP+ ports plus 4 QSFP ports and 24 active ports on the Q0U58B.

Power is the other deciding factor. HPE builds the SN3600B with one integrated power supply and does not offer a redundant supply for it. The SN3000B ships with one power supply and accepts an optional second, hot-swappable supply (QW939A). The SN6600B has two redundant, hot-swappable power supplies. If the fabric needs dual power feeds, look at the SN6600B or an SN3000B fitted with a second QW939A.

What speeds do SN3600B ports run at?

The switch supports 4, 8, 16 and 32Gb Fibre Channel. Port speed depends on the optic: HPE states that a 32Gb optic auto-negotiates to 32, 16 or 8Gb, and a 16Gb optic to 16, 8 or 4Gb. Check the listing for which optics, if any, are included.

Which way does air flow through these switches?

All three models use back-to-front airflow, meaning port-side exhaust. HPE describes the SN3000B as port-side exhaust and the SN3600B and SN6600B as back-to-front with non-port-side intake. Plan rack orientation so the port side faces the hot aisle.

What is the QW939A?

It is the optional hot-swappable power supply for the SN3000B. On this switch the cooling fans are built into the power supply, so a second QW939A adds both power and fan redundancy.

Will the AJ716B work in an SN3000B?

Yes. HPE lists the AJ716B 8Gb Short Wave B-series SFP+ as a transceiver option for the SN3000B, and notes that the older AJ716A is not supported in that switch.
