Lenovo ThinkSystem 930-4i - storage controller (RAID) - SATA / SAS 12Gb/s - PCIe 3.0 x8

The Lenovo ThinkSystem 930-4i Storage Controller (RAID) is a high-performance RAID-on-chip (ROC) adapters. This adapter supports RAID levels 0/1/10/5/50/6/60 as well as JBOD, and includes an extensive list of RAS and management features. The 930-4i features two channels and supports up to four internal SAS and SATA drives. MegaRAID FastPath software provides high-performance I/O acceleration for SSD-based virtual drives by using a low latency I/O path to increase the maximum I/O per second (IOPS) capability of the controller. It boosts the performance of applications with a highly random data storage access pattern.

• MegaRAID flash cache protection to avoid the possibility of data loss or corruption
• Auto-resume on array rebuild or array reconstruction after the loss of system power
• Online Capacity Expansion (OCE) allows the capacity of a virtual disk to be expanded
• Fast initialization quickly writes zeros to the first and last sectors of the virtual drive
