The **LSI 9286-8EHA MR SAS 6Gb/s RAID Controller** is a high-performance, enterprise-grade solution designed for storage-intensive environments. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros**
1. **Enterprise-Grade Performance**
The 9286-8EHA is built on LSI s proven SAS 6Gb/s architecture, delivering high throughput and low latency. It supports up to **8 ports** (4 internal 4 external via the bracket), making it suitable for large-scale storage arrays, NAS systems, or server expansions. The **Multi-Path (MR) mode** ensures redundancy and failover capabilities, which is critical for data integrity in mission-critical applications.
2. **RAID Functionality**
It supports **RAID 0, 1, 5, 6, 10, 50, and 60**, allowing for optimized performance, redundancy, and data protection. The ability to configure RAID levels on-the-fly (via the LSI MegaRAID Storage Manager) provides flexibility for different workloads, from high-speed caching (RAID 0) to fault-tolerant storage (RAID 6).
3. **Compatibility and Expansion**
The card is designed for **PCIe 2.0 x8 slots**, which is widely supported in enterprise servers (e.g., Dell PowerEdge, HP ProLiant, Supermicro, and custom builds). The included **bracket** allows for easy installation in a server s SAS backplane, enabling connections to SAS/SATA drives, SSDs, or other storage devices. It also supports **hot-swappable drives**, reducing downtime during maintenance.
4. **Software and Management Tools**
LSI provides robust management software, including:- **MegaRAID Storage Manager (MSM)**: A GUI-based tool for RAID configuration, monitoring, and troubleshooting.
- **Command Line Interface (CLI)**: For advanced users who prefer scripting or automation.
- **BIOS/UEFI Integration**: Allows RAID configuration during system boot (pre-boot environment).
The software is well-documented and supports remote management via IPMI or similar tools.
5. **Reliability and Support**
LSI (now part of Broadcom) has a strong reputation for storage controllers, with extensive driver support and firmware updates. The card is often used in data centers, suggesting a high level of reliability. Additionally, it is a **non-RAID "MR" model**, meaning it lacks onboard cache (unlike the "MR0" or "MR1" variants), which can reduce the risk of data loss in power failures (though battery backup units are still recommended for critical data).
6. **Cost-Effective for High-End Needs**
Compared to proprietary enterprise RAID cards (e.g., Dell PERC, HP Smart Array), the 9286-8EHA offers similar performance at a lower cost. It is a popular choice for DIY server builds, homelabs, or small-to-medium businesses looking for enterprise-grade RAID without the vendor lock-in.
7. **Backward and Forward Compatibility**
The card supports **SAS 6Gb/s** and can work with older **SAS 3Gb/s** drives (though performance will be limited). It also supports **SATA drives**, making it versatile for mixed environments. Future-proofing is limited, however, as it does not support NVMe or newer SAS speeds (e.g., 12Gb/s).
8. **Low Power Consumption**
As a passive or low-power active card (depending on the model variant), it does not significantly increase server power draw, which is beneficial for energy efficiency.
---
### **Cons**
1. **No Onboard Cache (MR Model)**
The **MR (Multi-Path Read) variant** lacks onboard cache, which means:- No write-back caching (data is written directly to disk, increasing risk during power loss).
- No battery backup unit (BBU) support, which is a critical feature for write caching in enterprise environments.
- Slightly slower write performance compared to models with cache (e.g., MR0 or MR1).
If write caching is required, you would need to pair this with a separate BBU or use a different variant (e.g., 9286-8i MR0).
2. **Limited to SAS 6Gb/s**
While 6Gb/s is sufficient for most SAS/SATA drives, it is not future-proof. If you plan to upgrade to **SAS 12Gb/s** or **NVMe drives**, this card will not support them. For modern high-performance workloads (e.g., databases, virtualization), a newer controller (e.g., LSI 9407-8i or Dell PERC H740) may be preferable.
3. **No Native NVMe Support**
The card does not support **NVMe over Fabrics (NVMe-oF)** or **PCIe-based NVMe SSDs**. If you are using NVMe drives, you would need a separate NVMe controller or host-based NVMe support (e.g., via the motherboard).
4. **Driver and Firmware Dependencies**
LSI controllers require **proper drivers** to function correctly. While the drivers are widely available, compatibility issues can arise with:- Older operating systems (e.g., very old Linux kernels or Windows versions).
- Custom or non-standard server builds (e.g., non-Dell/HP motherboards may require additional tweaks).
Firmware updates are important for security and performance, but some users report occasional compatibility quirks.
5. **No Native iSCSI or FC Support**
This is a **SAS/SATA-only** controller. If you need **iSCSI or Fibre Channel (FC) connectivity**, you would need a separate adapter (e.g., LSI 9207-8i for iSCSI or a dedicated FC HBA).
6. **Potential Overkill for Small Setups**
If you only need **basic RAID 1 or RAID 5** for a few drives, a simpler solution (e.g., a motherboard-integrated RAID controller or a software RAID) might suffice. The 9286-8EHA is best suited for **larger arrays (8 drives)** or **high-reliability needs**.
7. **No Native ZFS or Other Advanced Features**
Unlike some enterprise controllers (e.g., Dell PERC with ZFS support), the 9286-8EHA does not natively support **ZFS, Btrfs, or other advanced filesystem features**. It relies on the host OS for filesystem management.
8. **Physical Size and Installation Constraints**
The card is **full-height, full-length**, which may not fit in all server chassis (especially smaller or low-profile cases). The included bracket is standard, but some users report compatibility issues with non-standard backplanes.
9. **No Native Power Loss Protection**
Without a BBU, the card does not protect against data corruption during sudden power loss. While SAS drives have some write caching, it is not as robust as a BBU-equipped controller.
10. **Limited Vendor Support Outside Enterprise**
While LSI/Broadcom provides drivers and firmware, support for this card in **non-enterprise environments** (e.g., home labs, small businesses) may be limited compared to proprietary solutions (e.g., Dell PERC, HP Smart Array).

### **Conclusion**
The **LSI 9286-8EHA MR SAS 6Gb/s RAID Controller** is a **highly capable, cost-effective solution** for users who need **enterprise-grade SAS/SATA RAID functionality** in a **DIY server, NAS, or small-to-medium business environment**. Its strengths lie in **performance, reliability, flexibility (via RAID levels), and compatibility** with a wide range of hardware. It is particularly well-suited for:
- **Large storage arrays** (8 drives).
- **High-reliability applications** (e.g., backups, media servers, database storage).
- **Users who want to avoid vendor lock-in** (e.g., Dell PERC or HP Smart Array).
- **Budget-conscious buyers** who still need enterprise features.
However, it is **not ideal** for:- **NVMe or 12Gb/s SAS environments**.
- **Workloads requiring write caching** (without a BBU).
- **Small setups with fewer than 4 drives** (where a simpler solution may suffice).
- **Users needing iSCSI, FC, or advanced filesystem support**.
