The Power 770 model MMC enterprise server is designed to deliver outstanding price/performance, mainframe-inspired reliability and availability features, flexible capacity upgrades, and innovative virtualization technologies. The Power 770 model MMC features:
- Up to 64 POWER7 cores with four processor enclosures per server
- One IBM POWER7 processor card per processor enclosure: 16-core at 3.30 GHz or 12-core at 3.72 GHz
- Up to 4.0 TB of DDR3 memory with frequencies up to 1066 MHz, augmented with optional Active Memory Mirroring and Active Memory Expansion
- Enhanced I/O performance with two new, integrated POWER7 I/O controllers per processor drawer
- Optional Active Memory Mirroring
- Logical partitions -- up to 640 per system
The innovative IBM Power 770 server with POWER7 processors is a symmetric multiprocessing (SMP), rack-mounted server. This modular-built system uses one to four enclosures; each enclosure is four EIA units tall and is housed in a 19-inch rack. New to the model MMC server are two new, powerful POWER7 processor drawers. Each of the drawers contains a powerful POWER7 processor card, an enhanced POWER7 I/O backplane, and a new Integrated Multifunction Card. Each POWER7 processor card features 64-bit architecture designed with two single-chip module (SCM) POWER7 processors. Each POWER7 SCM enables either up to six or eight active processor cores with 2 MB of L2 cache (256 KB per core) and 32 MB of L3 cache (4 MB per core). Each POWER7 SCM processor is available at frequencies of 3.72 GHz with six cores or 3.30 GHz with eight cores. This new model server is available starting as low as four active cores and incrementing one core at a time through built-in Capacity on Demand (CoD) functions.
The POWER7 model MMC is a modular system that may be configured with one to four processor drawers. A system configured with up to four of these drawers using 6-core SCM processors will enable up to 48 processor cores running at frequencies up to 3.72 GHz. Or, a system configured with up to four drawers using 8-core SCM processors will enable up to 64 processor cores running at frequencies up to 3.30 GHz. A POWER7 system built with two or more model MMC processor drawers must be built with identical SCM POWER7 processors running at the same frequency.
Both of the above two processor drawers for POWER7 model MMC systems were designed with two integrated POWER7 I/O controllers that enhance I/O performance while supporting a maximum of six internal PCIe adapters and six internal small form-factor, SAS DASD bays. Also, both drawers are designed with a new Integrated Multifunction Card which provides four Ethernet ports (two 10 Gb and two 1 Gb),a serial port, and two USB ports. Virtualization of these Ethernet ports is provided through VIOS for AIX, IBM i, and Linux. Native (non-VIOS) usage of these ports is supported by AIX or Linux. The Integrated Virtual Ethernet or Host Ethernet Adapter is not used with the Power 770 model MMC.
Another design feature of POWER7 model MMC is the addition of 64 GB DDR3 DIMMs. These DDR3 DIMMs are available in both the POWER7 model MMC and MHC processor drawers, and each drawer supports up to 16 DIMM slots running at speeds up to 1066 MHz. When configured with four drawers, both POWER7 model MMC and MHC each support up to a maximum of 4.0 TB of DDR3 memory. All POWER7 DDR3 memory uses memory architecture that provides increased bandwidth and capacity. This enables operating at a higher data rate for large memory configurations. Also new with POWER7 model MMC is Active Memory Mirroring (AMM) for Hypervisor, which is available as an optional feature. Also available as an option is Active Memory Expansion, which enhances memory capacity.
