RAID radič Lenovo 4Y37A72483 PCI Express x8 12 Gbit/s SAS SATA

The Lenovo RAID controller 4Y37A72483 is an internal PCI Express x8 adapter that supports 12 Gbit/s SAS and SATA drives and implements multiple RAID levels including 0, 1, 5, 6, 10, 50 and 60. Designed as a RAID-on-chip (ROC) solution, the controller provides hardware RAID functionality, compatibility with Lenovo management tools and is intended for use in server and storage systems that require fault-tolerant and high-throughput disk arrays.

Advantages

The controller offers a high-speed 12 Gbit/s SAS/SATA interface over PCI Express x8, support for a wide range of RAID levels (including RAID-6 and RAID-60) for improved data protection and flexible array configurations, and integration with Lenovo management utilities for monitoring and configuration. As a RAID-on-chip adapter, it reduces CPU overhead compared with software RAID and is suitable for environments where hardware RAID is preferred.

Suitable for

• Enterprise and data center servers requiring hardware RAID
• Storage arrays that need RAID-6 or RAID-60 for enhanced redundancy
• Systems using SAS and SATA drives with PCI Express x8 expansion
