Configuring Onboard Sata Software Raid - Lenovo ThinkServer TS460 User Manual And Hardware Maintenance Manual

Notes:
• For server models with more than four HDDs or models that use SAS HDDs, a RAID card must be
installed.
• When the CPU utilization is high, it is recommended that you install a RAID card instead of using the
integrated software RAID controller for RAID 5 configuration.
• The ThinkServer EasyStartup program simplifies the process of configuring supported RAID and installing
supported operating systems and device drivers.
Before configuring RAID for your server, observe the following precautions:
1. Use HDDs that have the same capacity within a single RAID array.
2. Use HDDs that are of the same type (SATA or SAS) within a single RAID array.
3. Depending on the operating system, the primary RAID might be limited to 2 TB total drive capacity.
