Description

The Dell Unity 2×4 Port IO 32 Gb FC Upgrade (Part Number 405-ABBH) delivers a high-performance Fibre Channel connectivity option designed for the Dell Unity family of storage arrays. Whether you’re expanding your SAN footprint or looking to boost throughput for demanding workloads, this upgrade module offers 8 ports of 32 Gb/s Fibre Channel connectivity (2×4 ports) to deliver enterprise-class I/O performance.

With modern storage infrastructures requiring faster back-end connectivity, the phrase “Unity IO module 32 Gb FC” captures the essence of this upgrade. This module is especially useful in SAN environments where latency, throughput and redundancy are paramount. The “Dell Unity 32 Gb FC upgrade” keeps your infrastructure aligned with future demands.

From an e-commerce perspective, this part is frequently marketed under “Unity storage system expansion” or “32 Gb Fibre Channel upgrade” keywords, both of which serve procurement teams wanting to increase storage interconnect density without replacing the base storage system. According to pricing sources, the 405-ABBH lists around US $11,051 in upgrade form. 

Installation is straightforward: this is a plug-in I/O module for Unity arrays (such as Unity XT), and the process involves removing filler modules, installing the new module, and committing I/O ports through Unisphere.  After installation, you can map the ports for host connectivity and reap the benefits of 32 Gb Fibre Channel performance.

Key Features

  • 8 ports at 32 Gb/s Fibre Channel total (2×4 ports) for high-throughput SAN link-capacity
  • Designed specifically for the Dell Unity storage platform—ideal for “Unity storage system expansion”
  • Supports full-height PCIe / I/O module architecture in Unity enclosures
  • Enables upgrade path to 32 Gb Fibre Channel performance, preserving existing hardware and infrastructure
  • Enterprise-grade Dell support and compatibility with Unity arrays

Compatibility

This upgrade module is compatible with the Dell Unity family of storage arrays, such as Unity XT models, and leverages the I/O module slots in each Storage Processor (SP). According to Dell documentation, the Unity family supports a range of I/O module options, including 16 Gb and 32 Gb Fibre Channel modules. 

When installing this module, ensure you perform operations in pairs—one module per SP—to maintain HA configuration. The official “How to add a Unity IO Module” video details this process. 

Usage Scenarios

In enterprise SAN deployments where host applications require high bandwidth and low latency, upgrading to 32 Gb Fibre Channel through the “Dell Unity 32 Gb FC upgrade” module provides significant performance gains. This is relevant for databases, virtualization clusters, and streaming workloads where storage back-end traffic is heavy.

If you are planning a “Unity storage system expansion,” this module offers a cost-effective path to bolster I/O without replacing the entire array or disrupting live environments. The high-port count and speed make it ideal for consolidating multiple hosts or VMware clusters onto high-speed storage fabrics.

For e-commerce procurement, the listing often appears under “Unity IO module 32 Gb FC” or “32 Gb Fibre Channel upgrade”—terms buyers use when searching for upgrade-friendly parts compatible with existing arrays. It suits service providers, enterprise IT departments, and storage resellers offering upgrade options to their clients.

Whether you’re running a mid-tier Unity array or scaling an all-flash cluster, this module helps future-proof the system for next-generation Fibre Channel demands, aligning with larger SAN designs and higher-speed fabrics.

Frequently Asked Questions (FAQs)

1. Does the 405-ABBH module require matching modules in both storage processors (SPs)?

Yes. For full redundancy and HA configuration in a Dell Unity array, identical I/O modules should be installed in each SP (SP-A and SP-B). The upgrade process documentation recommends installing modules in pairs. 

2. Will upgrading to 32 Gb Fibre Channel require changes to my host HBA cards?

Yes. While the module provides the 32 Gb/s ports in the Unity array, hosts must have 32 Gb/s Fibre Channel HBAs to fully benefit from the speed. Using slower HBAs will limit throughput to the host side.

3. Is a firmware or code upgrade needed when installing this IO module?

In most cases, you should verify that your Unity OE code version supports the module. Dell’s upgrade paths documentation and module compatibility guide should be consulted. 

4. Can I mix this 405-ABBH module with existing 16 Gb Fibre Channel modules?

Yes, you can mix port speeds in some configurations, but you should ensure that host connectivity and zoning are managed accordingly. Also, performance will default to the lowest common speed for that link unless otherwise configured.
