The Lenovo 81Y4484 is a server RAID controller designed for System x servers, offering a straightforward path to improved storage performance and reliability. It plugs into a standard PCI Express slot and brings 512MB of dedicated cache memory, so frequently accessed data moves through the system quickly and steadily.
