Overview HPE P49735-001 1.92TB SAS Read-intensive SSD

The HPE P49735-001 1.92TB SAS 24Gbps Read Intensive 2.5-inch SFF solid state drive is engineered for modern Gen10 and Gen10 Plus server environments where high read throughput, low latency, and platform-level compatibility are critical. Built to Hewlett Packard Enterprise specifications and shipped with a hot-plug tray, this multi-vendor, digitally-signed firmware SSD provides predictable performance for read-dominant workloads such as virtualization, database read caches, analytics, content delivery, and large-scale file servers. The drive’s SAS 24Gbps interface makes it a natural fit for enterprise storage controllers and HPE server backplanes that require robust error handling, compatibility with RAID controllers, and advanced enterprise features not available on consumer NVMe or SATA drives.

Firmware and signed image advantages

Digitally-signed firmware provides several operational advantages for enterprise environments:

• Trusted platform validation: Controllers can verify firmware signatures so unauthorized or incompatible images are rejected.
• Simplified lifecycle management: HPE systems management tools recognize the drive for inventory, firmware updates, and support workflows.
• Reduced field incompatibilities: Signed firmware aligns drive behaviors (error handling, SMART reporting, power management) with HPE hardware expectations.

Hot-plug tray and serviceability

The P49735-001 ships with a hot-plug tray designed for HPE bays, enabling tool-less maintenance and rapid replacement. Hot-plug capability minimizes downtime in production environments and is essential for large server farms and data centers practicing quick-swap policies. The tray also includes proper caddies and handle ergonomics to match HPE Gen10 and Gen10 Plus chassis, preventing accidental engagement issues and ensuring proper seating in high-density enclosures.

Serviceability benefits

• Fast replacement during drive failure with minimal service interruption.
• Compatibility with drive activity LEDs, carrier latch mechanisms, and server-level hot-swap controls.
• Ease of inventorying and labeling at rack level — consistent part numbers simplify procurement and spares management.

Reliability, endurance, and data protection

Although classed as read-intensive, the P49735-001 includes enterprise features geared toward data integrity and reliability. Typical enterprise reliability features include robust error correction, power-loss protection mechanisms, thermal throttling and reporting, SMART telemetry, and background garbage collection tuned for read-priority workloads.

Endurance expectations

Read-intensive drives have endurance ratings that reflect fewer write cycles compared to mixed-use or write-intensive drives. For administrators, this means the P49735-001 is optimal in environments where writes are relatively low and predictable. Proper capacity planning and tiering policies (placing heavy-write workloads on write-optimized SSDs or HDDs) will maximize the life of the drive and preserve predictable performance.

SMART and telemetry

The drive supports vendor SMART attributes and telemetry reporting suitable for predictive failure analysis and drive health monitoring. HPE systems commonly surface these attributes through iLO and storage management interfaces where admins can build alerts and automated replacement workflows.

Data protection features

• Enterprise-grade ECC (error correcting code) to maintain data integrity
• Power-loss protection or write-buffer protection for critical metadata
• End-to-end data path protection where supported by controller and BIOS

Use cases and deployment patterns

Understanding where the HPE P49735-001 shines helps IT teams apply it properly within a storage hierarchy. Typical deployment patterns include:

1. Read caching and acceleration

Deploy as a read cache tier in hybrid arrays or inside server-local caching layers to accelerate repetitive reads and reduce backend latency for slower media.

2. Virtual desktop infrastructure (VDI)

In VDI scenarios that drive many read operations (boot storms, profile loads), read-intensive SSDs provide quick boot times and responsive session start without paying for the higher endurance overhead of write-intensive drives.

3. Content delivery and media streaming

For content repositories, video-on-demand servers, and content delivery points, the drive’s sequential read capability ensures smooth, concurrent reads and streaming for multiple clients.

4. Large scale databases (read-dominant)

Analytic databases and reporting platforms that rely heavily on read queries benefit from the drive’s optimization for read throughput and low-latency random reads.

Capacity planning and density considerations

At 1.92TB per 2.5-inch drive, the P49735-001 enables high-capacity, high-density storage configurations when deployed across multiple drive bays. Administrators should calculate usable capacity after RAID overhead, hot spares, and reserved overprovisioning to align spike handling and endurance. Typical strategies include:

• Using RAID configurations optimized for read performance (RAID 10, RAID 6 with read-optimized controllers).
• Pairing with higher endurance write-tier disks for mixed workloads.
• Building tiering policies so frequently-read data resides on the SAS SSD layer for best cost-to-performance ratio.

Rack and bay density

Because the drive is a 2.5-inch SFF device, it is ideal for servers and arrays that prioritize higher drive counts per chassis. This helps increase raw capacity per chassis while keeping power and cooling more favorable than some 3.5-inch solutions.

Comparisons and decision guidance

When architecting systems, teams often compare the P49735-001 against other SSD classes. Below are practical comparisons and decision criteria.

Read-Intensive SAS vs. Mixed-Use SAS

• Read-Intensive: Lower endurance (fewer DWPD), optimized firmware for read throughput and consistent read latency — better cost per GB for read workloads.
• Mixed-Use: Higher endurance and greater write tolerance — preferred where write operations are frequent and unpredictable.

SAS 24Gbps vs. SAS 12Gbps vs. NVMe

• SAS 24Gbps: Higher backplane throughput than 12Gbps SAS; enterprise features and controller compatibility; ideal for SAS controller ecosystems.
• SAS 12Gbps: Widely deployed and cost-effective, but with lower aggregate throughput compared to 24Gbps in multi-drive arrays.
• NVMe: Offers significantly lower latency and higher parallelism for single-drive performance but may require different chassis, controllers, or mezzanine cards and lacks SAS-level controller compatibility in older systems.

HPE P49735-001 vs. consumer SATA/enterprise SATA SSDs

SAS enterprise drives provide features rarely found on SATA consumer drives: enterprise-grade error handling, power-loss protection, bulk controller compatibility, and signed firmware. For data center environments requiring predictable behavior under controller management, SAS enterprise drives are preferable.

Supply-chain and procurement considerations

When procuring, ensure you’re buying genuine HPE P49735-001 units with matching trays and HPE product labeling. Multi-vendor compatibility may allow use in third-party systems but always validate signed firmware compatibility and HPE warranty/support terms. Keep a spares pool sized to expected mean-time-to-repair (MTTR) targets for your environment.

Real-world deployment checklist

1. Confirm server model and backplane accept 2.5-inch SAS 24Gbps drives.
2. Verify controller firmware and HPE compatibility lists for P49735-001 before procurement.
3. Plan RAID and tiering strategies aligned to read-intensive workloads.
4. Order matching hot-swap trays and spare units for quick replacements.
5. Establish SMART telemetry collection and alert thresholds in monitoring systems.
6. Schedule controlled firmware update windows and maintain rollback plans.
7. Document RMA and support procedures with HPE and resellers.
