HPE P9D93A — StoreFabric SN1100Q 16Gb Single-Port Fibre Channel HBA (PCIe 3.0, Low-Profile)

What it is: A single-port 16Gb Fibre Channel host bus adapter for HPE ProLiant (and other) servers. It drops into a PCIe 3.0 slot, presents one 16G FC port, and auto-negotiates to 8G/4G for mixed fabrics. Ideal for connecting servers to MSA / Alletra / Nimble / 3PAR or other FC SANs.

Why buyers pick P9D93A (plain English)

• Fast, simple SAN connectivity: light up a 16G FC link with low CPU overhead and predictable latency.

• Backwards-friendly: works on 8G or 4G fabrics while you upgrade the rest.

• Enterprise features you expect: Boot-from-SAN, NPIV, large queue depths, optional SR-IOV support on modern OSes.

• Fits tight racks: low-profile form factor with standard and LP brackets.

60-second spec box (P9D93A)

Host interface

• PCI Express 3.0 x8 (backwards compatible with PCIe 2.0)

FC port(s)

• 1 × 16Gb Fibre Channel (auto-negotiates 16/8/4G)

• SFP+ (FC) cage; uses standard LC-duplex FC optics/cables

Performance & features

• Line-rate 16G throughput on a single port

• NPIV, boot from SAN, T10 DIF/PI (end-to-end data protection), fabric login offloads

• Multi-pathing with native OS MPIO frameworks

Form factor / power

• Low-profile PCIe adapter (full-height bracket commonly included)

• Typical board power: single-digit watts (varies slightly by firmware/driver)

OS support (typical)

• VMware ESXi, Windows Server, RHEL, SLES (use current vendor driver/firmware matrix)

Cabling/optics

• Pairs with 16G/8G SW-LC SFPs for OM3/OM4 runs; LW optics for long-wave if your fabric uses them

What’s in the box

• HBA, bracket(s), quick start; optics and LC cables sold separately

Warranty

• Option-kit warranty (regionally 1–3 years; aligns with HPE terms)

Where it fits (and when to choose something else)

• Perfect for: ProLiant hosts that need a reliable FC uplink to an MSA/Alletra/Nimble/3PAR fabric for VM clusters, databases, VDI, or backup networks.

• Choose dual-port (e.g., SN1100Q 2-port) if you want host-level port redundancy on one card.

• Choose 32G FC if your core/arrays already run Gen6 FC and you want higher throughput and future-proofing.

Quick design tips (no-regret)

• Two paths minimum: for true HA, use two HBAs or a dual-port card, cabled to two independent FC switches.

• Match optics to fabric: 16G short-wave SFPs for OM3/OM4 intra-DC; long-wave for campus spans.

• MPIO everywhere: enable native MPIO (or DSMs) and set your array’s preferred pathing policy.

• Firmware/driver hygiene: align adapter firmware and OS driver with your SAN vendor’s interoperability guide.

TL;DR

P9D93A is the single-port 16G FC HBA you drop in to give a server rock-solid SAN connectivity—PCIe 3.0, NPIV, boot-from-SAN, low-profile bracket, and backwards-compat with 8G/4G while you modernize the fabric.
