IBM p5 550 Express

IBM p550 Express servers 550, 550Q

The 550Q express uses up to 8-core scalability using Quad-Core Module technology powered by IBM?s latest Quad-Core Module (QCM) 1.65 GHz POWER5+ processor cores 64-bit CPU.� The System p5 550 Express platform is a 2- or 4-core database server with 2.1 GHz POWER5+ dual-core processor modules.�

The 550 and 550Q p550 Express servers utilize logical partitioning (LPAR) technology implemented via optional IBM Virtualization Engine? systems technologies and the operating system. LPAR allows the processors to run separate workloads in different partitions on the same server, thereby helping lower costs. Partitions are shielded from each other to provide a high level of data security and increased application availability. Dynamic LPAR allows clients to dynamically allocate many system resources to application partitions without rebooting, enhancing availability.

Built for attachability, the 550 and 550Q p550 Express servers offer tremendous configuration flexibility to meet most capacity and growth requirements. Clients have extensive growth potential in choice of 19-inch rack-mount or deskside packages with up to 64GB of DDR2 memory, up to eight optional I/O drawers resulting in 31.2TB of disk storage and up to 59 hot-plug PCI-X slots.

The System p5 550 and 550Q Express servers are designed to give clients the flexibility to run the AIX 5L and Linux operating systems concurrently in micro-partitions.
