HP 815983-001 96W Smart Storage Battery With 145Mm Cable For Dl By Ml By Sl Servers

The HP 815983-001 is a 96W smart storage battery with a 145mm cable, intended for compatible DL, ML, and SL servers; it suits server owners or IT teams seeking this specific HP part.

Recommended For

• HPE ProLiant DL, ML, or SL Gen9 server owners replacing a failed or aging 96W Smart Storage Battery with the matching 145mm-cable part.
• Server administrators using a compatible HPE Smart Array controller with flash-backed write cache who need backup power to protect cached data during an unexpected power loss.
• IT teams restoring RAID-controller cache features after a battery fault, once they have confirmed that 815983-001 is the correct spare for their server and controller configuration.
• Operators with multiple compatible storage devices in one server who want a centralized backup-power source for supported controllers or NVDIMMs rather than separate batteries for each device.

Real-World Use Scenarios

• When a compatible Gen9 server is handling RAID writes, the battery supports flash-backed write cache, allowing the controller to use its cache while keeping a power-loss backup path available.
• If server power is unexpectedly lost while data is in the controller’s write cache, the battery supplies backup power so that the cache contents can be copied to flash; it does not keep the server running.
• In a compatible server with multiple drive controllers, one battery pack can provide flash-backed write-cache backup for all the server’s drive controllers, rather than requiring a separate pack for each controller.
• When a server is brought back into service after its battery has been discharged or stored for a long time, a POST alert may appear and the Smart Array cache may remain disabled until the battery has enough charge to enable caching.
