My Buying Guides on Lsi Sas 9300 8i
When I was looking to upgrade my storage setup, the LSI SAS 9300-8i caught my attention because of its strong reputation for reliability and performance. If you’re considering this RAID controller, here’s what I learned and what helped me make an informed decision.
Understanding What the LSI SAS 9300-8i Is
The LSI SAS 9300-8i is a host bus adapter (HBA) designed to connect multiple SATA or SAS drives to your system via PCIe. What I liked is that it supports 12Gb/s SAS speeds, which means faster data transfers compared to older models. It’s commonly used in servers, workstations, and high-performance desktops.
Compatibility and Interface
Before buying, I checked if my motherboard had a compatible PCIe slot. The 9300-8i uses a PCIe 3.0 x8 interface, so make sure your system supports that for optimal speeds. It supports up to 8 internal SAS or SATA drives, which was perfect for my storage needs.
Performance and Features I Found Useful
- 12Gb/s SAS Speed: This was a huge plus for me because it significantly improved my read/write speeds.
- Firmware and Driver Support: LSI (now Broadcom) provides solid firmware updates. I made sure to download the latest firmware to avoid compatibility issues.
- IT Mode and IR Mode: The card supports both, but I preferred IT mode for simple HBA passthrough to my ZFS setup. If you want RAID functionality, IR mode would be more suitable.
Number of Ports and Expandability
The 9300-8i has two SFF-8643 connectors, each supporting 4 lanes, so you get 8 ports total. I appreciated this because it allowed me to connect multiple drives or expand using SAS expanders if needed.
Power and Cooling Considerations
From my experience, the card runs cool, but since it’s often used in dense server environments, proper airflow is essential. I made sure my case had good ventilation to avoid thermal throttling.
Pricing and Value
When I researched prices, the LSI 9300-8i was reasonably priced for its performance class. It’s a great value if you want enterprise-grade reliability without paying for excessive features you might not use.
Installation Tips from My Experience
- Make sure to update the firmware before installation to ensure compatibility with your OS.
- Use quality SAS cables to avoid connection issues.
- Check your BIOS settings to enable the PCIe slot and configure boot priorities if necessary.
Final Thoughts
The LSI SAS 9300-8i proved to be a robust and reliable solution for my storage needs. If you need a high-performance SAS HBA with solid support and compatibility, this card is worth considering. Just be sure to verify your system’s compatibility and plan your storage layout before purchasing.
