Overview

The LSI Logic LSI00278 MegaRAID 9265-8i is a high-performance PCI Express SAS RAID controller designed for enterprise servers and workstations that demand fast, reliable access to large storage arrays. With 8 internal SAS ports operating at 6Gb/s, this controller can directly connect to multiple SAS or SATA drives and — through the use of SAS expanders — scale to manage up to 240 drives in a single configuration. It supports a comprehensive set of RAID levels including 0, 1, 5, 6, 10, 50, and 60, giving storage administrators the flexibility to prioritize performance, redundancy, or a balance of both depending on the workload.

The onboard cache memory is a key feature for environments running databases, virtualization platforms, or other I/O-intensive applications, as it buffers frequently accessed data to reduce latency. For production deployments, pairing the controller with an optional battery backup unit is recommended to protect cached write data in the event of an unexpected power loss. The 9265-8i has established itself as a dependable component in data center and enterprise storage builds where consistent throughput and data integrity are non-negotiable.

Pros & Cons

👍 Pros

  • Supports RAID 0, 1, 5, 6, 10, 50, and 60 for flexible data protection configurations.
  • 6Gb/s SAS interface provides high throughput for demanding storage workloads.
  • 8 internal ports with expander support for scaling up to 240 drives.
  • Compatible with both SAS and SATA drives, offering deployment flexibility.
  • Onboard cache memory accelerates random I/O performance for databases and virtual machines.

👎 Cons

  • PCI Express form factor requires a compatible server or workstation with an available x8 slot.
