HPE AG804A at a Glance

Enterprise Storage Built Around Performance

The AG804A combines several characteristics that made high-speed Fibre Channel storage valuable in enterprise environments: 15,000RPM rotational performance, dual-port connectivity, 2/4Gbps Fibre Channel support, hot-swap capability, and a 3.5-inch 1-inch-height form factor.

Its 450GB capacity may appear modest compared with modern storage devices, but capacity is only one consideration in a legacy SAN. Compatibility, rotational speed, interface technology, enclosure support, and drive firmware can be equally important when maintaining an established enterprise storage array.

Designed for HPE EVA Infrastructure

The AG804A belongs to the HPE StorageWorks EVA drive ecosystem. HPE's compatibility information specifically separates the AG804A/AG804B family for EVA 4000/6000/8000 systems from the AG803A/AG803B family used with EVA 4400/6400/8400 and M6412 enclosures.

That distinction is important when purchasing a replacement drive. Two HPE Fibre Channel drives can have similar capacity and performance specifications while being intended for different EVA enclosures or platforms.

450GB Capacity for Enterprise Storage

A Practical Capacity for Legacy SANs

The 450GB storage capacity provides a useful balance for older enterprise storage arrays where multiple disks operate together as part of a larger storage pool.

Within an EVA environment, individual drives do not necessarily operate as isolated storage devices. They contribute to the overall storage architecture, where capacity, redundancy, availability, and performance are managed across the array.

The AG804A can therefore be useful as a replacement disk for an existing array rather than simply as a standalone 450GB hard drive.

Ideal for Maintaining Existing Storage

Replacing individual disks can be much more practical than replacing an entire SAN platform. Organizations with established EVA systems may have applications, configurations, management processes, and infrastructure built around their existing storage environment.

A compatible AG804A can help keep that infrastructure operational while reducing the disruption associated with a complete storage migration.

15000RPM Performance

Built for High-Speed Disk Access

The AG804A features a 15,000RPM spindle speed, placing it among the faster traditional enterprise hard drives of its generation.

A higher rotational speed reduces the time required for the platter to rotate to the desired position, helping improve access responsiveness. This characteristic made 15K Fibre Channel HDDs particularly attractive for workloads involving frequent random storage operations.

Suitable for Performance-Oriented Workloads

The drive is well suited to compatible enterprise applications where fast conventional disk performance is important. Potential workloads include database environments, transactional applications, virtualization storage, shared enterprise data, and other SAN-based applications.

While modern SSDs offer substantially higher performance, a 15K Fibre Channel HDD remains useful when maintaining an older storage platform that was designed around this technology.

Dual-Port Fibre Channel Connectivity

2/4Gbps Fibre Channel Support

The AG804A provides 2/4Gbps Fibre Channel connectivity, allowing it to operate within the Fibre Channel architecture used by compatible HPE EVA storage systems.

Fibre Channel was designed specifically for enterprise storage networking, providing dedicated connectivity between storage systems and the servers accessing them.

For organizations maintaining legacy Fibre Channel SANs, matching the original interface remains essential. A modern SATA or SAS drive cannot simply be substituted for a Fibre Channel drive because the interface and storage architecture are fundamentally different.

Dual-Port Design

Dual-port connectivity is an important feature in enterprise storage because it supports redundant paths between the drive and storage infrastructure.

Redundant connectivity helps reduce dependence on a single path and fits naturally into the highly available architecture traditionally associated with enterprise SAN environments.

3.5-Inch Large Form Factor Design

Compact 1-Inch Drive Height

The AG804A uses a 3.5-inch Large Form Factor with a 1-inch drive height. This specification is important when matching the drive to its intended enclosure.

Enterprise storage hardware is highly dependent on physical compatibility. A drive can have the correct capacity and interface but still be unsuitable if its physical dimensions or carrier configuration do not match the enclosure.

Designed for Compatible HPE Enclosures

The AG804A is associated with the M5314 Fibre Channel drive enclosure for compatible EVA environments. HPE compatibility information identifies AG804A as the appropriate 450GB 15K drive family for EVA 4000/6000/8000 systems.

This makes it especially important to check the existing enclosure before ordering a replacement.

Hot-Swap Enterprise Storage

Simplifying Drive Replacement

Hot-swap capability is one of the most useful characteristics of enterprise storage drives. In a compatible storage environment, a failed disk can be replaced without shutting down the entire storage system.

For businesses running critical applications, minimizing downtime is essential. Hot-swappable drives allow storage administrators to respond to hardware failures more efficiently while keeping the broader infrastructure operational.

A Valuable Spare for Older EVA Systems

As enterprise hardware ages, sourcing an exact replacement can become increasingly difficult. Keeping compatible AG804A drives available as spares can help organizations respond quickly when a disk fails.

A spare drive can be particularly valuable for storage environments that contain important business data and cannot afford prolonged hardware replacement delays.

HPE EVA Compatibility

HPE StorageWorks EVA 4000

The HPE EVA 4000 is one of the primary platforms associated with the AG804A.

The drive provides the Fibre Channel interface, rotational speed, capacity, and physical characteristics expected by compatible EVA storage configurations.

HPE StorageWorks EVA 6000

The HPE EVA 6000 is another key platform for the AG804A. HPE support information specifically identifies AG804A/AG804B as the 450GB 15K drive family for EVA 4000/6000/8000 systems.

This makes the AG804A a relevant replacement option for organizations maintaining EVA 6000 infrastructure.

HPE StorageWorks EVA 8000

The HPE EVA 8000 also supports this drive family in compatible configurations.

For older EVA 8000 installations, using a drive designed for the platform can be a straightforward way to maintain existing storage capacity and performance without undertaking a complete system replacement.

AG804A and AG803A: Why the Difference Matters

Similar Specifications, Different Storage Environments

The AG804A and AG803A can cause confusion because both are associated with 450GB 15K Fibre Channel storage and have very similar specifications.

However, the platform and enclosure compatibility differ. HPE's drive matrix identifies AG804A/AG804B for EVA 4000/6000/8000, while AG803A/AG803B are associated with EVA 4400/6400/8400 and M6412 shelves.

This is a crucial distinction when ordering a replacement.

For example, an HPE community discussion specifically advises using AG804A for an EVA 6000 and distinguishes it from AG803A, which is intended for the M6412 enclosure environment.

Always match the drive to the actual EVA model and enclosure rather than selecting a drive solely by capacity or spindle speed.
