Emulex LightPulse 21000 10 Gbit/s HBA

The Emulex LightPulse 21000 is a single-port Fibre Channel host bus adapter that delivers 10 Gbit/s connectivity over an LC interface. It targets server administrators who need to add or replace a Fibre Channel link in a PCI-X 1.0a slot for SAN access.

PCI-X 1.0a bandwidth and single-port limit

The card uses the PCI-X 1.0a host interface, which constrains total throughput to the capabilities of that bus generation rather than newer PCI Express standards. Only one Fibre Channel port is provided, so the adapter cannot support multipath configurations or port redundancy without installing a second card.

Plug-in card installation in legacy servers

The low-profile plug-in card measures 4.4 inches by 9 inches and fits standard PCI-X slots found in older rack or tower servers. Installers must verify that the motherboard still offers an available PCI-X 1.0a slot and that the operating system includes a driver for the LightPulse 21000, as modern distributions may no longer bundle support for this interface generation.

Questions about this item

Should I pick the single-port LP21000 or a dual-port version?

This model provides one LC port for a single Fibre Channel link; if you need two independent connections, a dual-port adapter is required.

What does the 10 Gbit/s rate mean once the card is installed?

It delivers up to 10 Gbit/s Fibre Channel throughput over the single LC port using FCoE on 10 Gb/s Ethernet.

What does the PCI-X 1.0a interface limit in practice?

The card plugs into a PCI-X 1.0a slot, so bus bandwidth and slot availability determine the maximum sustained transfer rate.
