P49743-001 HPE 15.36TB SAS 12GBPS Read Intensive Sff SSD.

HPE P49743-001 15.36TB Product category overview

The HPE P49743-001 15.36TB Read-Intensive 2.5" SFF SAS 12Gb/s Multi-Vendor BC Hot-Swap SSD with Tray sits in the enterprise storage category for mission-critical servers and array upgrades. This category targets data centers, virtualization hosts, database appliances, analytics platforms, and any infrastructure that demands high capacity, low latency, and read-optimized endurance. Although the model number and vendor branding are specific to Hewlett Packard Enterprise (HPE), the broader category covers enterprise 2.5-inch SAS solid-state drives (SSDs) — particularly read-intensive, dual-port SAS 12Gb/s devices that support multi-vendor backplane compatibility and hot-swap trays for easy serviceability.

Choose a 15.36TB read-intensive SAS SSD

Enterprises select a 15.36TB read-intensive SAS SSD when they need:

• Large usable capacity in a compact 2.5" small-form factor (SFF).
• Predictable read performance for read-dominant workloads like OLAP, content delivery, and cache layers.
• SAS 12Gb/s connectivity for backward compatibility with enterprise controllers and high throughput.
• Hot-swap tray compatibility to keep service windows short and downtime minimal.
• Multi-vendor compatibility so the drive works across different server and storage OEMs, easing procurement and replacement.

Key specifications and what they mean

Form factor — 2.5" SFF

The 2.5-inch SFF (small form factor) design packs high capacity in a small footprint. This is ideal for dense server racks and blade chassis where maximizing capacity per bay matters. SFF drives are standard in modern enterprise servers and storage arrays.

Interface — SAS 12Gb/s (dual-port)

SAS 12Gb/s (Serial Attached SCSI) is the enterprise interconnect standard providing full-duplex, high-bandwidth, and dual-port redundancy. Dual ports allow multipath I/O and failover between controllers, improving resilience in storage networks. Compared with SATA, SAS offers better error handling, zoning, and enterprise features favored by data centers.

Capacity — 15.36TB

At 15.36 terabytes, this SSD provides a large block of hot storage for big data sets, VM libraries, and read caches. High density reduces the number of drives needed, lowering power, cooling, and management overhead.

Workload class — Read-Intensive (RI)

Read-intensive SSDs are optimized for workloads where read operations significantly outweigh write operations. They offer a balance of endurance, capacity, and cost — delivering solid read IOPS and throughput while providing adequate write endurance for caching, indexing, or log-streaming scenarios.

Multi-Vendor Backplane Compatibility

“Multi-vendor BC” implies the drive has firmware and mechanical specifications designed to operate correctly across different server/backplane vendors. This reduces compatibility hassles when installing the drive into non-HPE chassis or when mixing parts from multiple OEMs.

Hot-Swap Tray included

A hot-swap tray (carrier) enables tool-less insertion and removal while the host remains powered — critical for enterprise uptime. Trays often include positive retention and LED activity indicators for easier system maintenance.

Endurance and data reliability

Endurance on a read-intensive SSD is lower than on mixed-use or write-intensive drives, but still sufficient for the intended workload. Endurance is commonly expressed as drive writes per day (DWPD), terabytes written (TBW), or a warranty period tied to a specified TBW. Key reliability features include:

• Power loss protection (PLP) to flush volatile buffers and protect user data in the event of sudden power failure.
• End-to-end data path protection (ECC, CRC) to ensure data integrity through the controller and interface.
• Wear leveling & bad block management to maximize usable life of NAND flash.
• SMART telemetry and predictive failure logs for proactive monitoring and replacement planning.

Comparing read-intensive vs mixed-use vs write-intensive SSDs

Choosing the right class depends on I/O patterns:

• Read-Intensive (RI): Best for read-heavy databases, caches, content delivery, and boot volumes. Lower endurance, better capacity-to-cost ratio.
• Mixed-Use (MU): Balanced read/write workloads such as general VM hosts, smaller databases, and application servers.
• Write-Intensive (WI): High logging, heavy transactional DBs, and analytics ingest where writes dominate; highest endurance and cost.

Use cases and workload examples

Virtualization hosts and VDI

Read-intensive SSDs excel in virtual desktop infrastructure (VDI) environments where many VM images perform simultaneous read requests for boot storms and application launches. A 15.36TB SSD helps house many VM images on fewer spindles with lower contention and latency.

Database read replicas and analytics

Analytical query nodes and read replicas benefit from low latency and high throughput for scanning large tables and serving read requests. Using read-optimized SSDs for replicas reduces the load on primary storage while keeping query responsiveness high.

Cache and tiering layers

High-capacity SSDs are ideal for cache tiers in hybrid storage architectures. They serve hot data quickly while cheaper HDD tiers store cold data. The drive’s endurance supports caching patterns where reads dominate and writes are bounded by cache eviction policies.

Content delivery and media libraries

Streaming platforms and media asset libraries require high sustained read throughput. A dense pool of 15.36TB SAS SSDs reduces the number of drives and spindles necessary to deliver consistent streaming performance.

Buying considerations and procurement checklist

When procuring HPE P49743-001 or similar 15.36TB read-intensive SAS SSDs, follow a checklist to ensure you get the right product for your environment:

1. Confirm part numbers: HPE part numbers can have multiple SKUs (with/without tray, different firmware). Verify the exact SKU matches your need.
2. Check firmware baseline: Make sure firmware is compatible with your server models and controller firmware.
3. Validate physical carrier: Ask whether the drive comes with an HPE tray and whether it fits your chassis bays.
4. Warranty and RMA terms: Confirm warranty duration, on-site vs return, and RMA SLAs that meet your operational tolerance.
5. Price vs endurance tradeoff: Read-intensive drives cost less per GB than write-intensive models — select based on your workload profile.
6. Bulk discount and lifecycle refresh: Plan drive replacement cycles and negotiate volume pricing for fleetwide upgrades.

Vendor and third-party distribution

Purchasing through authorized HPE channels ensures factory-backed warranty and support. However, multi-vendor compatibility often allows buying equivalent enterprise SAS SSDs from third-party distributors. When using third-party parts, ensure:

• Product authenticity and serial number traceability.
• Clear warranty handoff (manufacturer vs distributor).
• Availability of firmware update images and support documentation.

Comparison checklist: HPE P49743-001 vs Enterprise SSD

• Effective capacity (after overprovisioning).
• Endurance rating (DWPD/TBW).
• Read and write IOPS under typical queue depths.
• Sequential throughput.
• Included tray/carrier and its compatibility.
• Security features (SED, secure erase).
• Warranty terms and RMA procedures.

Price-to-performance and density

A 15.36TB read-intensive drive offers excellent price per usable gigabyte for read-heavy workloads. Calculate TCO not just on purchase price but energy, rack density, and administrative overhead — fewer drives usually mean lower power and simpler maintenance.

Additional resources and next steps for buyers

Buyers should request sample drives for validation in their environment, confirm RAID/controller compatibility, and plan a pilot to measure real workload behavior before a large rollout. Engage vendor support for firmware recommendations and to register serial numbers for warranty coverage.
