Product identity

This is a refurbished Lenovo ThinkServer RAID 500 PCIe adapter, part number 4XB0G45758, designed as a SAS controller for ThinkServer RD350 and RD450 platforms. It provides hardware RAID 0, 1 and 10 with a dedicated I/O controller supporting 6Gb SATA and SAS drives.

Who this suits

IT teams maintaining Lenovo ThinkServer RD350 or RD450 systems who need a PCIe RAID adapter for up to eight SATA or SAS disks with RAID 0, 1 or 10. Buyers who require RAID 5 must purchase the separate RAID 5 upgrade option, and those needing AnyRAID form-factor cards or higher-end RAID 710, 720i or 720ix features should look at other models in the same family.

Deciding specification

The adapter connects through a standard PCIe slot and presents a SAS controller interface with 6Gb SATA and SAS support for up to eight drives, making the host interface and drive count the key factors when confirming compatibility with your server chassis and backplane.

Questions about this item

Does the 4XB0G45758 RAID 500 PCIe Adapter fit the ThinkServer RD350 and RD450 chassis?

The adapter is designed for the ThinkServer RD350 and RD450 systems and installs into a compatible PCIe slot on the server motherboard.

How is the RAID 500 PCIe Adapter installed, and what step is often missed?

Insert the card into an available PCIe slot, connect the SAS cables to the backplane, then apply the RAID 500 RAID 5 Upgrade key (4XB0G45759) in the management utility to enable RAID 5 — this software activation step is frequently overlooked.

What maintenance or replacement will the RAID 500 PCIe Adapter need over time?

The adapter supports up to 8 SAS or SATA drives; plan to replace any failed drive and, if the onboard battery-backed cache module loses capacity, replace that cache module to maintain write performance.
