3.84 TB SAS SSD for 3PAR 8000

This HPE K2P91B solid-state drive delivers 3.84 TB of capacity in a 2.5 inch form factor. It uses a SAS 6Gb/s interface and multi-level cell NAND flash. The drive is designed for internal installation in HPE 3PAR StoreServ 8000 storage systems.

Upgrade from smaller 3PAR SAS drives

The drive replaces lower-capacity SAS SSDs inside a compatible 3PAR 8000 array. The capacity jump is worth it when the storage system needs more usable space for mixed workloads without adding extra drive bays. It fits the same SFF bay and uses the existing SAS backplane.

Limited to SAS 6Gb/s and 3PAR 8000 compatibility

The SAS 6Gb/s interface caps maximum throughput at the link speed of the backplane. The drive is qualified only for HPE 3PAR StoreServ 8000 storage systems and is not supported in other servers or arrays. Buyers who need a different interface or broader server compatibility cannot use this model.

Questions about this item

Does the 2.5" SAS drive fit a standard SFF bay in the HPE 3PAR StoreServ 8000?

Yes, the 2.5" form factor matches the small-form-factor bays used by the HPE 3PAR StoreServ 8000 storage system.

How is the K2P91B installed in the 3PAR 8000 enclosure, and what step is often missed?

Slide the drive into an empty SFF slot until the carrier clicks; the step often missed is engaging the release lever fully so the SAS connector seats on the backplane.

When will the 3.84 TB MLC SSD need replacement under typical 3PAR 8000 workloads?

The MLC NAND is rated for mixed-use endurance; replacement timing depends on actual write volume, so monitor SMART wear indicators in the 3PAR management console.
