The HPE H221 Host Bus Adapter (HBA) is compatible with select HPE ProLiant Gen8 and Gen9 servers, and provides customers with the flexibility and speed they have come to expect from Hewlett Packard Enterprise. It features eight external SAS ports (two x4 external connectors) that now support HP SAS tape drives as well as 6Gb/s SAS and SATA hard drives. The H221 HBA has been optimized for connection to the HPE P2000 G3 SAS Modular Smart Array, D2000 and D6000 Disk Enclosures (only with Gen8 servers), and MSA2040 SAS storage and is designed to drive cost-effective and reliable scalability in today’s data centers.
