Lenovo 4XB0F28690 ThinkServer RAID 110i RAID 5 Upgrade Key

Purpose-built RAID 5 activation

This Lenovo ThinkServer RAID 110i upgrade key unlocks RAID level 5 on compatible controllers. It is intended for server administrators who need parity-based redundancy without replacing the existing RAID card. The licence applies specifically to the 110i firmware and enables the feature immediately upon installation. No additional hardware is required to activate the capability.

Capacity and headroom

The key activates RAID 5 across the drives already attached to the supported controller, providing stripe with distributed parity for usable capacity equal to N minus one drives. It does not increase the number of supported drives or the controller’s maximum array count beyond the base firmware limits. Performance scales with the underlying drives and backplane; the key itself imposes no throughput ceiling. Arrays larger than the controller’s native drive-count limit remain unsupported.

Build quality and day-to-day implications

Delivered as a new licence entitlement, the upgrade is applied through the server management interface or BIOS, requiring no physical card swap or cabling changes. Once activated, the RAID 5 configuration persists across reboots and firmware updates tied to the 110i platform. The electronic delivery method means no media handling, and the activation is bound to the server’s existing controller serialisation.
