• Up to two GX+ slots (4-core 520)
• Up to 2700 GB of disk storage in the system unit
• One media bay for DVD-ROM or DVD-RAM
• One media bay for tape drive

The Power Systems 520 Express server includes EnergyScale technology that provides features such as power trending, power-saving, capping of power, and thermal measurement. The Power 520 Express can be configured to incorporate a 1-, 2-, or 4-core processor, up to 64 GB of system memory, five PCI adapters, and multiple media devices, as desired. This flexibility is made available through the many optional features for the Power 520 Express.

IBM Power 550

The IBM 8204 Power 550 Express deskside and 4U rack-mount server (8204-E8A) supports up to four POWER6 processor cards and 2-, 4-, 6-, and 8-core configurations. The POWER6 processors in this server are 64-bit, dual-core modules on a single processor card with 32 MB of L3 cache, and 8 MB of L2 cache, and eight DDR2 memory DIMM slots. The Power 550 Express server offers four processor card slots that can contain 2-core IBM POWER6 processor cards running at either 3.5 or 4.2 GHz.

The Power 550 Express features:

• Powerful POWER6 processors
• 2-, 4-, 6-, and 8-core configurations
• Tower or rack-mount configuration
• Integrated 10/100/1000 dual-port Virtual Ethernet with optional 10/100/1000 quad-port or dual-port 10 Gb Virtual Ethernet
• EnergyScale technology
• Up to 256 GB of memory with four 4.2 GHz processors installed
• Five I/O slots in the system unit
• Two GX+ slots (one slot usable in 2-core 550)
• Up to 2700 GB of disk storage in the system unit
• One media bay for DVD-ROM or DVD-RAM
• One media bay for tape drive

The POWER6 processors available in the Power 550 Express server operate at a frequency of 3.5 or 4.2 GHz. The DDR2 DIMMs run at speeds up to 667 MHz. A full 8-core system can contain up to 256 GB of memory. The Power 550 Express server contains EnergyScale technology that provides features such as power trending, power-saving, capping of power, and thermal measurement. These features, enabled via IBM Systems Director Active Energy Manager^tm for Power software, allow the customer to measure the energy of the system and direct policies toward the energy-efficient operation of the server, while the underlying hardware automatically adjusts to deliver the desired operating solution. Also available in this model is a choice of quad gigabit or dual 10 Gb integrated host Ethernet adapters. These native ports can be selected at the time of initial order. Virtualization of these integrated Ethernet adapters is supported.

The Power 550 Express system unit contains six 3.5-inch SAS DASD bays, which can accommodate up to 2700 GB of disk storage. All DASD are direct dock and hot pluggable. A slim media bay is available for a DVD-ROM or DVD-RAM, and a half-high media bay is available for a tape drive.
