HPE 462918-001 P411/1G PCIe x8 Controller

HPE 462918-001 Smart Array P411 PCIe x8 SAS RAID Controller

The HPE 462918-001 is a Smart Array P411 storage controller board designed for selected HPE ProLiant servers. It provides external SAS connectivity through two Mini-SAS ports and supports RAID configurations for compatible disk enclosures.

This PCI Express 2.0 x8 controller supports SAS transfer rates of up to 6Gb/s and SATA transfer rates of up to 3Gb/s. It is particularly relevant for businesses maintaining legacy HPE storage environments or replacing an existing P411 controller.

Important: HPE lists 462918-001 as the controller board without cache memory or backup power. A 1GB flash-backed write cache configuration requires the appropriate additional components.

HPE 462918-001 Technical Specifications

Connecting External SAS Storage

The Smart Array P411 is designed to connect a compatible server to external SAS storage enclosures.

Its two external Mini-SAS ports allow the controller to communicate with supported disk enclosures using the appropriate cables.

Unlike an internal storage controller, the P411 is primarily intended for external storage connectivity.

This makes it useful when a business needs to maintain an existing disk enclosure or replace a failed controller without changing its complete storage infrastructure.

Understanding the P411 Cache Options

The P411 controller supports different cache configurations, including battery-backed write cache (BBWC) and flash-backed write cache (FBWC).

HPE offered several P411 controller kits:

• 462830-B21: P411 controller with 256MB cache.
• 462832-B21: P411 controller with 512MB BBWC.
• 572531-B21: P411 controller with 1GB FBWC.

The spare part number 462918-001 identifies the controller board itself. The installed cache module, battery or capacitor must be confirmed separately.

If your existing controller uses a 1GB FBWC module, check whether the replacement board is compatible with the original cache hardware and whether the required components are included.

RAID Features and Storage Protection

The Smart Array P411 supports RAID 0, RAID 1 and RAID 1+0 configurations.

Additional RAID levels, including RAID 5, 5+0, 6 and 6+0, depend on the installed cache configuration and applicable feature licensing.

RAID can help provide storage redundancy when correctly configured, but it is not a replacement for maintaining independent data backups.

When replacing an existing RAID controller, confirm the array configuration, firmware compatibility and condition of the connected drives before making changes.

New and Refurbished HPE 462918-001

New HPE 462918-001

A New or unused controller may suit businesses maintaining older ProLiant servers and external SAS storage systems. Confirm whether the product is supplied as a bare board or with additional cache components.

Refurbished HPE 462918-001

A Refurbished P411 controller can be a cost-conscious replacement for supported legacy storage environments.

Before ordering, ask whether the controller has been tested for hardware detection, external SAS connectivity and controller functionality.

For both conditions, confirm the bracket type, supplied accessories, warranty and UK delivery arrangements.

What to Check Before Replacing a P411 Controller

Before purchasing HPE 462918-001, verify:

• The existing controller’s part number and hardware revision.
• The server’s PCIe slot and controller compatibility.
• The connected external SAS enclosure model.
• The required Mini-SAS cables.
• Whether the existing controller uses BBWC or FBWC.
• Whether cache modules and backup power components are included.
• The firmware and operating system requirements.

These checks can help avoid purchasing an incomplete or unsuitable replacement.
