HPE 632429-003 400GB Enterprise Performance SSD

The HPE 632429-003 is a 400GB Small Form Factor (2.5-inch) enterprise-class solid state drive that uses a Serial Attached SCSI (SAS) interface rated at 6.0 Gbps. Built and supplied as an Enterprise Performance (EP) SSD, this part is designed for mission-critical workloads where predictable I/O, low latency, and endurance are required. The drive is commonly supplied as a hot-pluggable SFF module compatible with HPE ProLiant servers spanning multiple generations, making it a straightforward upgrade or replacement option for administrators managing mixed-generation server estates. :contentReference[oaicite:0]{index=0}

Form factor, interface and compatibility

This SSD follows the 2.5-inch Small Form Factor (SFF) standard and is delivered either with or without the smart carrier/drive tray depending on the vendor listing. The use of a 6Gb/s SAS interface ensures backward compatibility with legacy SAS controllers while delivering enterprise-class signalling for consistent throughput under mixed read/write patterns. That combination of SFF packaging and SAS 6Gb/s makes the 632429-003 widely compatible with HPE ProLiant G4–G7 (and often referenced against G8/G9 product families in reseller catalogs) server bays that expect hot-pluggable SFF SmartDrive modules. For procurement and inventory clarity, vendors often list the OEM part number (632429-003) alongside alternate HPE model identifiers like EO0400FBRWA or 632494-B21 in cross-reference tables.

Performance profile and workload fit

As an Enterprise Performance-class drive, the 632429-003 is optimized for mixed I/O workloads that require both sustained throughput and high IOPS. This makes the drive suitable for database log partitions, virtual machine datastores, OLTP workloads, metadata volumes, and other I/O-sensitive tiers. The combination of the SLC/enterprise-grade NAND (as listed by some resellers for similar part numbers) and enterprise firmware yields low latency under queue depth, consistent write performance, and a focus on endurance metrics important to datacenter operators. Drive behavior under heavy mixed read/write load tends to be more predictable than consumer-grade SSDs because enterprise drives include power-loss protection, capacitors or firmware safeguards, and tailored garbage collection/over-provisioning strategies.

Endurance, reliability and enterprise firmware

Enterprise-class HPE SSDs are engineered to sustain demanding write cycles and to maintain performance stability over long service windows. Although exact endurance figures (e.g., drive writes per day or total terabytes written) may vary by batch and firmware, the 632429-003’s positioning as an EP-class drive signals higher-rated endurance than mainstream client drives. Administrators should pair SSD selection with expected workload intensity and consider over-provisioning, RAID level, and drive spare strategies to maximize longevity. Additionally, genuine HPE drives carry vendor-validated firmware and serial numbers which help ensure predictable behavior in a ProLiant environment, and also simplify support interactions with HPE or authorized resellers.

Power-loss protection and data integrity features

Enterprise SSDs aimed at server use typically include mechanisms to minimize data loss during sudden power events, such as on-drive capacitors and firmware routines that flush write caches in the correct order. While the product pages and reseller listings for the 632429-003 emphasize “mission critical” and “enterprise class” credentials, explicit details about power-loss protection and the internal DRAM/backup architecture should be verified on vendor datasheets or HPE technical documentation for the exact SKU you purchase. Choosing drives that explicitly list power-loss protection and end-to-end data path protection will reduce the risk of partial write corruption in high-transaction environments.

Deployment scenarios and best practices

For administrators deploying the HPE 632429-003, the most common scenarios are as follows: replacing failed OEM drives in older ProLiant servers, standardizing on enterprise SAS SSDs across a mixed-generation fleet, and creating high-performance tiers within SAN or direct-attached server arrays. Because the drive fits hot-pluggable 2.5-inch SFF bays, it can be used in RAID arrays managed by HPE Smart Array controllers, or as individual volumes for hypervisor datastores. When deploying these drives, it’s important to ensure your server’s firmware, RAID controller firmware, and HPE system ROM are within validated versions to avoid compatibility or SMART reporting issues that can occur when mixing legacy controllers and newer drive firmware revisions.

Capacity planning and tiering strategies

At 400GB capacity per drive, the 632429-003 is well-suited for I/O-heavy tiers where capacity-per-dollar is less important than IOPS-per-dollar and latency predictability. Use these drives for smaller, high-performance volumes such as database transaction logs, VM boot volumes, and caching layers. For bulk capacity requirements, combine these EP-class 400GB drives with higher-capacity, lower-cost SATA/SAS HDDs in tiered arrays so that hot data is served from the SAS SSD tier while colder, less latency-sensitive data stays on HDD tiers. This hybrid approach balances performance and cost while extending the practical value of each SSD in the storage topology.

Hot-swap replacement and firmware considerations

Because the 632429-003 is commonly offered with a hot-pluggable SmartDrive carrier, field replacement is straightforward in HPE ProLiant chassis designed for 2.5-inch drives. When replacing drives, swap in identical or firmware-compatible parts where possible to maintain RAID resiliency and predictable rebuild times. Keep a record of firmware versions, and where applicable, use HPE’s Service Pack for ProLiant (SPP) or vendor tools to update system ROM and controller firmware before or after replacement. If you’re integrating third-party or refurbished units, verify that the drives report proper serial numbers and firmware identifiers that are acceptable to your monitoring tools and HPE support policy.

Interoperability with HPE ProLiant generations and controller compatibility

Reseller listings and product cross-references show that 632429-003 has been marketed for ProLiant G4–G7 server families, and similar part numbers appear in catalogs for G8/G9 contexts as well. This broad compatibility stems from the standard SFF form factor and SAS interface, but practical interoperability depends on the exact controller and chassis firmware level. HPE Smart Array controllers and many third-party SAS HBAs accept 6Gbps SAS SSDs generically, but for full SmartDrive identification, health reporting, and integrated drive firmware management you should match the OEM part number or use HPE-certified alternatives. If uncertain, consult HPE’s official compatibility matrix or contact HPE support with the exact server model and controller SKU to confirm support for the 632429-003 in your configuration.

Monitoring, SMART data and proactive maintenance

Enterprise SSD maintenance is continuous: monitor SMART attributes, endurance counters, and controller-level drive health reports. HPE’s management interfaces (such as iLO and HPE Insight) along with Smart Storage Administrator tools provide early-warning telemetry about impending failures and predictive spare usage. Regularly reviewing drive health will help you spot abnormal wear, firmware anomalies, or manufacturer recalls. Maintain a drive replacement pool and hot spares proportionate to your RAID groups so you can restore resiliency quickly without impacting production workloads.
