Adaptec Series 7 Family

Microsemi Adaptec Series 7H
Host Bus Adapters (HBAs)

8- and 16- port PCIe Gen3 HBAs offer high-performance I/O and low latency with broad device compatibility, scalability and flexibility

The Series 7H family of Microsemi Adaptec SAS/SATA host bus adapters (HBA) offers the ideal high performance solution for data centers requiring maximum I/O connectivity and low latency.

Flexible, Scalable, Customizable
Utilizing Microsemi's 16x6G SAS protocol controller, Series 7H HBAs support both Serial Attached SCSI (SAS) and Serial ATA (SATA) interfaces to provide the flexibility to use cost effective, high-capacity SATA drives and/or high-performance SAS drives.

The Series 7H HBAs feature a low-profile MD2 form factor and mini SAS HD connectors that facilitate easy installation and cable connections in dense server environments.

Series 7H HBAs can directly connect up to 16 high-performance SSD/HDD devices without expanders to offer the highest performance and lowest latency I/O connection.

Up to 16 SAS/SATA ports allow for maximum I/O throughput, and the OS drivers use MSI-X to leverage all available host CPU cores to achieve maximum performance and utilize full PCI Gen3 bandwidth.

New mini SAS HD Connectors and SAS HD Cables
These connectors allow for greater flexibility in configuration options by supporting up to 16 native SAS/SATA ports in a Low-profile MD2 form factor. The new connectors can be combined with a wide range of Adaptec SAS HD cables, including straight connectors or Adaptec's first to market right angle connectors.

Compatibility, Reliability, and Support
Series 7H HBAs have been extensively tested with third-party systems and devices to deliver the utmost in compatibility. These HBAs are equipped with both uEFI and legacy BIOS options as well as a CTRL-A configuration utility and HII-based BIOS tools.
