HPE 873566-001 400GB SAS 12G 2.5″ SSD

HPE 873566-001 400GB SAS 12G 2.5in SSD

The HPE 873566-001 is the maintenance spare version of HPE’s 400GB 12G SAS small form factor SSD, the part number that appears on service labels and in HPE parts documentation when this drive family needs replacing in a ProLiant server. Euroland IT Store holds 873566-001 in UK stock, available new and refurbished, with same-day dispatch on most orders placed before our cut-off.

Administrators generally meet this part number one of two ways: a predictive failure alert from iLO, or a physical drive fault that has left an array running degraded. In both cases the job is to fit a like-for-like replacement quickly, and HP Spare 873566-001 does exactly that. The drive arrives in the correct hot-plug carrier with genuine HPE firmware, so the Smart Array controller identifies it, accepts it into the existing logical drive and starts the rebuild without manual intervention.

Beyond break-fix work, this 400GB SAS SSD is a practical building block in its own right. Its 12G interface and flash endurance suit transaction logs, caching volumes, hypervisor boot devices and other roles where write consistency beats raw capacity. Organisations standardising older ProLiant estates often buy several 873566-001 units at refurbished pricing to retire the last spinning disks from performance-sensitive arrays.

The corresponding factory option kit is 873359-B21, useful to know when reconciling asset registers that mix installation and service part numbers. As dedicated suppliers of HPE parts, we can confirm which number matches your installed drives from a photo of the label or your server serial number, then quote for exactly what you need, whether that is one drive or a dozen.

Benefits

Exact-match replacement is the cheapest form of risk management in server storage. Fitting 873566-001 keeps the array homogeneous, avoids firmware mismatches and gets a degraded RAID set back to full protection in the shortest possible time. Compared with keeping ageing drives in service, proactive replacement with tested flash also cuts the likelihood of a second failure mid-rebuild, the scenario every administrator wants to avoid.

Refurbished stock brings the price of that insurance down considerably, and every unit is tested before dispatch; new drives are available where policy dictates. Volume pricing applies when you are refreshing multiple bays.
