Know before you buy
Yes, the SAS 9300-8i is backward compatible with previous generations of SAS and SATA drives, allowing you to integrate older hardware into your current storage setup.
Yes, it features a low-profile form factor and includes both a low-profile and a full-height bracket, making it compatible with a wide range of server chassis.
While the card has eight physical ports, it supports up to 1024 SAS or SATA devices when used in conjunction with SAS expanders.
This adapter uses two SFF-8643 mini-SAS HD connectors. You will need cables that feature an SFF-8643 connector on the controller end and the appropriate connector for your specific drive backplane or individual drives.
The SAS 9300-8i is a Host Bus Adapter (HBA) designed primarily for pass-through connectivity. It does not provide hardware RAID functionality, so it is best suited for software-defined storage solutions like ZFS or unRAID.
The card supports transfer rates of up to 12Gb/s for SAS drives and 6Gb/s for SATA drives, utilizing an eight-lane PCIe 3.0 interface to ensure high throughput.
