HPE 873351-B21 400GB SAS 12G SFF 2.5in SSD

The HPE 873351-B21 is a 400GB SAS 12G solid state drive in the 2.5 inch small form factor, sold as an HPE option kit for ProLiant server deployments. Euroland IT Store supplies 873351-B21 new and refurbished, shipped quickly from UK stock to businesses, public sector buyers and resellers.

Smaller capacity SAS SSDs like this one earn their keep in roles where write performance and endurance matter more than raw space. Typical uses include database log volumes, caching tiers, write-heavy application partitions and fast boot or scratch volumes in ProLiant rack and tower servers. The 12G SAS interface provides dual-port connectivity and deeper command queuing than SATA, so the drive holds its performance under the sustained mixed I/O that enterprise workloads generate.

As a B21 option kit, HPE 873351-B21 arrives ready to install in a hot-plug drive bay, presenting to the Smart Array controller with correct HPE firmware and full integration into iLO health monitoring. This makes it straightforward to add flash performance to an existing server estate without introducing unqualified hardware. The equivalent HP Spare number for maintenance replacements is 873563-001, which we also stock, so you can match whichever part number your asset system or HPE documentation references.

For procurement teams, the choice between new and refurbished comes down to policy and budget. Refurbished 873351-B21 drives are tested before dispatch and priced well below list, while new units suit projects that require unused stock. Either way, our team can confirm compatibility with your specific ProLiant generation before you commit, and quote for single drives or full-array quantities.

Benefits

Deploying 873351-B21 gives a ProLiant server the storage response times that databases and busy applications demand, without the cost of populating every bay with large drives. Because it is a genuine HPE part, warranty position, firmware behaviour and monitoring all stay predictable, and a matched drive avoids the array rebuild issues that third-party media can trigger.

Refurbished units offer a cost saving that is hard to ignore when you are buying several drives, and each one is tested before it leaves us; new stock is on hand where required. Keeping a spare in the cupboard is cheap insurance for production arrays.
