HPE P49745-001 800GB SAS 24Gbps 2.5″ MU SSD Hard Drive

P49745-001 is a spare-number reference for an HPE 800GB 24G SAS Mixed Use SFF SSD family, useful when an existing enterprise flash installation needs maintenance. The documented product family is 800GB, uses SAS 24Gb/s, and is described as a 2.5-inch SFF Mixed Use solid-state drive with Basic Carrier. This page focuses on service-led flash replacement, rather than repeating the purchasing description of other numbers in the same family. This spare number can anchor a replacement search for a supported 800GB 24G SAS Mixed Use SSD.

Maintaining 24G enterprise flash

An 800GB Mixed Use SSD is chosen for a balance of read and write activity, not simply for raw capacity. The workload and drive generation matter alongside the part number. The part number P49745-001 should be retained in inventory records alongside the server model and the identity visible on the installed unit. That makes future maintenance more straightforward and helps procurement distinguish a commercial option, a spare, an assembly and a model number.

Where Mixed Use flash fits

SAS 24Gb/s describes the drive interface generation. A supported controller and backplane are needed for the intended configuration; a drive should not be treated as a direct replacement for older Smart Carrier or SATA media merely because it fits a 2.5-inch bay. In practice, drive selection is a system-level decision: the bay, backplane, controller, firmware qualification and existing RAID design all influence suitability. The most useful product record describes the exact component family rather than only its capacity.

Working with an existing storage platform

A replacement project is often about preserving a known working configuration. For P49745-001, the interface and carrier provide useful clues, but the supported HPE server configuration remains the deciding factor. This is particularly important in mixed-generation estates, where two drives may share capacity yet differ in firmware, tray design or controller requirements.

The P18438-B21 listing illustrates a different identifier or storage family; matching the intended server generation is more useful than comparing capacity in isolation. The aim is to choose storage that fits the current platform and the required workload, rather than to change technology during a routine service event.

Keeping an accurate service history

Raw capacity is only the starting point for an enterprise storage plan. RAID protection, available drive bays, future expansion and backup requirements influence the usable result. For P49745-001, recording the installed part and the array to which it belongs is valuable during future repairs. The same record can support stock planning and reduce time spent identifying hardware when a maintenance window is short.

Why exact product identification matters

The interface name describes one part of the technology, but it does not identify every compatible server. A drive may be physically similar to another product yet use a different carrier or firmware family. Keeping the full P49745-001 reference, rather than only a generic capacity description, makes quotations and asset records more useful. It also supports a clearer distinction between an upgrade and a like-for-like replacement.

Balancing maintenance and future upgrades

A drive intended for active application data may have different priorities from one used for less frequently accessed information. Capacity, write activity, latency and resilience all matter. An established platform can benefit from retaining a known supported storage family, while a major capacity increase may be better handled as a planned storage refresh. Treating those as separate decisions can make purchasing more predictable.

Condition choices for established estates

A New P49745-001 can suit planned upgrades, spare holdings and compatible installations where unused stock is preferred. A Refurbished unit can offer a practical option for maintaining a server already using the same storage family. Actual condition, available health information and warranty should be evaluated for the item offered. The original HPE product-family warranty does not automatically describe a reseller-supplied refurbished drive.

Some are alternative identifiers within the same family, while others belong to a different capacity or interface generation. The relationship is useful for identifying components, not a claim that every linked drive is a direct substitute.

A useful reference for future maintenance

This spare number can anchor a replacement search for a supported 800GB 24G SAS Mixed Use SSD. For globally managed server estates, keeping the exact HPE identifier alongside the asset record can simplify future service and purchasing. It also helps teams in different locations understand which component was installed and why it was selected.

Source the documented drive family

Euroland IT Store can help source HPE P49745-001 in New or Refurbished condition where available. Share the relevant server and existing part number when requesting a matching storage component, so the enquiry can be handled against the intended platform.

Frequently Asked Questions About HPE P49745-001

What is the main use of HPE P49745-001?

It is a service-spare reference associated with an 800GB SAS 24G Mixed Use SFF SSD family. It is relevant when maintaining a supported HPE storage configuration that uses this interface generation.

What does Mixed Use mean for an 800GB enterprise SSD?

Mixed Use identifies an endurance profile intended for workloads that involve meaningful reads and writes. It does not mean every application will achieve the same performance or write life.

Is a SAS 24G SSD interchangeable with a SAS 12G drive?

Not automatically. Drive generation, carrier, server backplane and controller support all matter, even when both products use SAS and a 2.5-inch form factor.

Can this SSD be used for virtualisation or database storage?

Mixed Use flash can suit workloads with frequent reads and writes, including some virtualisation and database applications. The final choice depends on write volume, latency requirements and the supported server configuration.

What matters most when sourcing Refurbished P49745-001?

The actual drive's health, condition and remaining useful endurance matter. The warranty and included carrier should also be described for the specific unit.
