How to choose a host bus adapter
An HBA hands each drive straight through to the operating system, with no RAID layer. That is what ZFS, software-defined storage and hyperconverged stacks expect, and it is why administrators sometimes reflash or replace a RAID controller with one. Memory Clearance lists 3,869 Host Bus Adapter listings from 44 brands, led by Dell (937), HP (863) and QLogic (350) where shown online.
The category is not purely host bus adapters by name. Of the 2,638 listings with a stated product type, 2,318 are tagged Host Bus Adapter; the rest split across Ethernet Card (174), Fibre Channel Controller (44), SAS Controller (32) and Network Adapter (10), among others. A card typed as Ethernet or Network Adapter is an iSCSI or FCoE adapter, not a SAS or Fibre Channel HBA, so read the listing name before you buy.
Fabric decides the search first. SAS runs at 6, 12 or 24 Gb/s; Fibre Channel at 8, 16 or 32 Gb/s, with 64 Gb/s on the newest cards; iSCSI and FCoE ride ordinary Ethernet. Listing names here span that range, from HP's 4 Gb/s AE136A up through the 64 Gb/s SN1700Q, plus the Ethernet-typed adapters for iSCSI or FCoE. Match the fabric already wired into your array first: a 32 Gb/s Fibre Channel HBA is inert on a SAS-only backplane.
Port count and location matter almost as much. Of the 1,615 listings with a stated port count, 795 show 2 ports and 598 show 1, with 4, 8, 16 and 3-port cards behind those. An internal SAS HBA connects to a drive backplane with mini-SAS connectors; an external SAS HBA uses mini-SAS or mini-SAS HD copper connectors instead, while external Fibre Channel cards use SFP or SFP+ cages. Sample listings include PCIe 3.0 x8 and PCIe 4.0 x8 cards; a narrower slot than the card is wired for caps its speed. On Fibre Channel cards, an SR or LR suffix in the listing name marks the optic as installed; a card without one may need one bought separately.
Condition and price follow the same split as everything else here. 172 listings are marked New and 1,301 Refurbished; the catalogue records no condition on the other 2,396, so ask for it when requesting a quote. Refurbished is a normal condition for this part class: an HBA has no moving parts, so its specification is fixed by the part number rather than by age. 1,031 of the 3,869 listings carry an online price; the rest carry a Request for Quote button, and quotes are answered weekdays 8:00 am to 5:00 pm PST on (800) 733-1169.
Host bus adapter buying questions
What is the difference between an HBA and a RAID controller?
A RAID controller aggregates drives into one or more virtual volumes and hides the member disks from the operating system. A host bus adapter passes each drive straight through instead, which is what ZFS and software-defined storage expect. It is also why administrators reflash a RAID card into HBA, or IT, mode. Full comparison: RAID controller vs HBA guide.
Is a refurbished host bus adapter reliable?
1,301 of the 3,869 listings here are marked Refurbished, against 172 New; the catalogue records no condition on the rest, so ask for it at quote. An HBA has no moving parts, so its specification is fixed by the part number rather than by age. See condition grades.
Will a PCIe 4.0 host bus adapter work in an older PCIe 3.0 slot?
Yes. PCIe is backward and forward compatible: a PCIe 4.0 card negotiates down to PCIe 3.0 speed in an older slot, and a PCIe 3.0 card runs at full speed in a newer PCIe 4.0 or 5.0 slot. Lane width matters just as much: an x8 card in a slot wired for only x4 lanes is capped at half its rated bandwidth, even if the connector fits x8.
How do I find the right host bus adapter for my server?
Read the part number off the card you are replacing, or pull it from your server's hardware inventory, and search it directly. A Dell, HP or Lenovo number maps to a QLogic, Broadcom or Emulex equivalent behind it. If you only know the server model and fabric, send both with a quote request. See the part number guide.
