Lenovo ThinkSystem RAID 5350-8i Controller

The ThinkSystem RAID 5350-8i is an entry-level 12 Gb SAS/SATA internal RAID adapter designed for Lenovo ThinkSystem servers. It provides a cost-effective RAID solution for small to medium business customers. The cacheless adapter supports RAID levels 0, 1, 10, 5 and 50. It includes support for Lenovo management tools.

Suits budget-focused internal storage arrays

This adapter suits administrators building internal SAS or SATA arrays who need hardware RAID without cache overhead. It works for direct-attached drive configurations using supported RAID modes. Buyers who require cache protection, higher port counts or external connectivity should select a different controller model.

Cacheless 12 Gb SAS/SATA RAID adapter

The defining specification is the cacheless design combined with 12 Gb SAS/SATA interface support. This determines the performance ceiling and data protection level for the supported RAID levels. Verify that your server chassis and drive backplane match the internal connector layout before purchase.

Questions about this item

How do I install the ThinkSystem RAID 5350-8i into a server, and what step is often missed?

Insert the adapter into a compatible PCIe slot, connect internal SAS cables to the eight ports, then enable the controller in the system BIOS before creating arrays.

What maintenance or replacement will the 5350-8i need over time?

As a cacheless design it has no battery or super-capacitor to replace; only firmware updates via Lenovo management tools are required.

What limit appears first on the 5350-8i during sustained heavy I/O?

Without onboard cache the write throughput is bound directly to the attached SAS or SATA drives, so drive latency becomes the bottleneck.
