Frequently Asked Questions

Is P64844-B21 interchangeable with P65193-001?

Yes — P64844-B21 is the option kit and P65193-001 is the spare part. Both are HPE 1.92TB NVMe PCIe 4.0 read-intensive U.3 SSDs with Basic Carrier — fully interchangeable in Gen10 Plus and Gen11 supported configurations.

Does P64844-B21 support PCIe 3.0 platforms?

PCIe 4.0 NVMe drives are backward compatible with PCIe 3.0 U.3 backplanes at reduced bandwidth. Full PCIe 4.0 performance requires Gen10 Plus or Gen11 with PCIe 4.0 NVMe backplane support.

What is the advantage of 1.92TB vs. 960GB for read-intensive workloads?

1.92TB doubles capacity per bay, reducing drives needed for large read-intensive datasets. For analytics, VDI, and content repositories, fewer 1.92TB drives replace more 960GB drives while maintaining the same total capacity with fewer bays consumed.

The HPE P64844-B21 1.92TB NVMe PCIe 4.0 U.3 option kit delivers high-capacity flash storage for HPE ProLiant Gen10 Plus and Gen11. Get it in stock at the best price — order today.
