HPE AP731A Key Features

450GB Enterprise Storage Capacity

The AP731A provides 450GB of storage capacity, making it suitable for enterprise applications, shared storage, databases, virtualization environments, and other workloads running on compatible HPE EVA systems.

Its capacity is particularly useful for maintaining existing storage arrays where matching drive specifications and array compatibility are more important than simply choosing the highest-capacity modern drive.

10,000RPM Performance

With a 10,000RPM spindle speed, the AP731A is designed for faster rotational performance than conventional 7,200RPM hard drives.

The 10K RPM design helps provide responsive storage performance for workloads involving frequent data access, making the drive well suited to traditional enterprise applications and Fibre Channel SAN environments.

4Gbps Fibre Channel Interface

The drive features a 4Gbps Fibre Channel interface, designed for Fibre Channel storage architectures used by HPE StorageWorks EVA systems.

Fibre Channel provides dedicated storage connectivity and was widely adopted for enterprise SAN deployments requiring dependable, high-performance communication between servers and centralized storage.

3.5-Inch Large Form Factor

The AP731A uses a 3.5-inch Large Form Factor (LFF) design intended for compatible HPE storage enclosures.

Physical form factor is an important consideration when replacing an enterprise storage drive. A drive may have the correct capacity but still be unsuitable if its form factor, interface, firmware, or enclosure compatibility does not match the existing system.

Hot-Swap Capability

Hot-swap functionality allows compatible storage systems to replace a drive without shutting down the entire storage enclosure.

This is particularly valuable in enterprise environments where minimizing downtime is a priority. When a drive fails, an appropriate replacement can be installed while the storage system remains operational, subject to the array's configuration and maintenance procedures.

Compatibility With HPE StorageWorks EVA Systems

HPE EVA 4400

The AP731A is suitable for compatible HPE StorageWorks EVA 4400 configurations using the M6412A Fibre Channel drive enclosure.

For organizations still operating EVA 4400 infrastructure, a compatible 450GB 10K Fibre Channel drive can provide a straightforward replacement for failed or aging disks.

HPE EVA 6400

The drive is also intended for compatible HPE StorageWorks EVA 6400 environments.

Using a matching enterprise drive helps maintain the existing storage architecture without introducing an incompatible interface or form factor.

HPE EVA 8400

The HPE StorageWorks EVA 8400 is another compatible platform for this class of M6412A Fibre Channel drive.

Organizations maintaining EVA 8400 installations can use compatible replacement drives to keep existing storage arrays operational and extend the useful life of established infrastructure.

HPE M6412A Storage Enclosure

The M6412A is a Fibre Channel drive enclosure designed for HPE EVA storage environments. The AP731A's 3.5-inch LFF design, Fibre Channel interface, and enterprise storage characteristics make it suitable for compatible M6412A configurations.

Always verify the exact drive option, enclosure configuration, and storage-system requirements before installation.

Why Choose the HPE AP731A?

Ideal for Legacy Enterprise Storage

Modern storage environments increasingly use SSD and NVMe technology, but many organizations continue to operate established HPE EVA systems because of their reliability, existing configurations, and integration with business infrastructure.

Replacing individual drives can be considerably more practical than replacing an entire storage platform.

The AP731A provides a matching enterprise storage solution for compatible legacy EVA environments, helping businesses keep existing systems operational.

Designed for Fibre Channel SAN Environments

Unlike standard desktop or consumer hard drives, the AP731A is designed for an enterprise Fibre Channel storage environment.

Its 4Gbps Fibre Channel interface and 10,000RPM performance make it appropriate for traditional SAN applications where reliable storage connectivity and predictable performance are required.

Useful as a Replacement or Spare Drive

The AP731A can be used as a replacement for a failed drive or kept as a spare for planned maintenance.

Maintaining compatible spare drives is especially useful for organizations operating older storage equipment, where finding an exact replacement quickly can become increasingly difficult.

Enterprise Applications

Database Storage

The 10,000RPM spindle speed makes the AP731A suitable for compatible enterprise environments running database applications that require dependable disk access.

Virtualization

Legacy virtualization platforms can use Fibre Channel SAN storage for centralized virtual machine storage. A compatible AP731A can help maintain existing storage infrastructure supporting these environments.

Business File Storage

The drive can also support shared file storage and other business applications hosted on compatible HPE EVA arrays.

Enterprise SAN Infrastructure

With its Fibre Channel interface and hot-swap design, the AP731A is built around the requirements of traditional enterprise SAN environments where availability and centralized storage management are important.

AP731A vs. AP731B

Understanding the Part Numbers

When purchasing replacement HPE storage drives, you may encounter both AP731A and AP731B references.

These part numbers are associated with the 450GB 10K Fibre Channel drive used with the M6412A storage environment. The 518734-001 spare part number may also appear in listings for this drive.

Because enterprise hardware listings can use different option, spare, or assembly numbers, buyers should compare the complete specifications rather than relying on a single part-number match.

Before ordering, confirm the following:

• 450GB capacity
• 10,000RPM spindle speed
• 3.5-inch LFF form factor
• 4Gbps Fibre Channel interface
• M6412A compatibility
• EVA 4400, 6400, or 8400 compatibility
• Appropriate firmware and drive configuration

Installation Considerations

Confirm the Failed Drive

Before removing a disk, verify the exact physical drive identified by the storage management system. Removing the wrong disk from an active array can create unnecessary storage problems.

Check Drive Compatibility

Confirm that the replacement matches the existing EVA configuration. Capacity, interface, form factor, firmware, and supported drive type can all affect compatibility.

Follow Proper Hot-Swap Procedures

Although the AP731A is designed for hot-swap environments, drive replacement should always follow the storage system's recommended maintenance procedure.

After installation, monitor the array to ensure the replacement drive is recognized correctly and that any rebuild or reconstruction process completes successfully.
