The IBM 1726HC4 DS3400 Dual Controller FC is a refurbished Fibre Channel storage controller assembly designed for IBM System Storage DS3400 environments. Built for SAN connectivity, it supports Fibre Channel host attachment and dual-controller operation to help maintain availability and predictable access to shared storage in data center and server room deployments.
This controller option is typically used for controller replacement, lifecycle extension, or maintaining spares for installed DS3000-series arrays. When planning a DS3400 refresh or repair, it is often sourced alongside related IBM components such as SYSTEM BOARD, expansion parts, and other platform-specific modules to keep configurations consistent across sites.
Key Features
Key technical characteristics for storage maintenance and integration in DS3400-based Fibre Channel SAN setups:
- Dual-controller DS3400 configuration support to help maintain access to volumes during controller maintenance or failure scenarios.
- Fibre Channel (FC) host connectivity to integrate with SAN fabrics and FC-capable servers and HBAs.
- Compatibility with IBM System Storage DS3400 arrays to support like-for-like controller replacement in existing installations.
- Designed for DS3000 family deployments (for example DS3400) to simplify spares strategy across similar IBM storage platforms.
- Controller-level management and monitoring functions to support operational visibility and fault isolation in enterprise storage environments.
- Support for multipath/high-availability storage designs (when implemented in the host and fabric) to reduce the impact of component failures.
- Hot-serviceable design expectations for DS3400-class arrays to reduce planned downtime during controller swaps (array procedures apply).
- Enterprise-grade build intended for 24/7 operation to fit continuous workloads in data centers and comms rooms.
Refurbished Quality and Warranty
This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished controllers are a practical way to extend the lifecycle of installed DS3400 storage, reduce electronic waste, and control budget compared to buying new.
All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware shipping worldwide from Denmark; for broader platform maintenance you can also source complementary items such as MEMORY and RAID CONTROLLER for related IBM infrastructure where applicable.
