4 IBM Power 750 and 760 Technical Overview and Introduction
The Power 760 server supports a maximum of 64 DDR3 DIMM slots, 16 per 0/12-core
processor DCM. Memory features (two memory DIMMs per feature) supported are 8, 16, 32,
and 64 GB and run at a speed of 1066 MHz. A system with four DCMs installed has a
maximum memory of 2048 GB. Also, the optional Active Memory Expansion can enable the
effective maximum memory capacity to be much larger than the true physical memory.
Innovative compression and decompression of memory content using processor cycles can
enable memory expansion up to 125% for AIX partitions. A server with a maximum of
2048 GB can effectively be expanded to greater than 4 TB. This can enhance virtualization
and server consolidation by allowing more partitions or running more work with the same
physical amount of memory.
The Power 760 server offers great I/O expandability. In addition to the six PCIe Gen2 slots in
the system unit, up to four 12X-attached I/O drawers (FC 5802 or FC 5877) add up to 40 PCIe
Gen1 slots. This set of PCI slots can deliver extensive connectivity to LANs, switches, SANs,
asynchronous devices, SAS storage, tape storage, and more. For example, more than 64 TB
of SAS disk storage is supported.
The Power 760 server includes six SFF SAS bays. This offers up to 5.4 TB HDD capacity or
up to 3.6 TB SSD capacity. All SAS disks and SSDs are 2.5-inch SFF and hot swappable. The
six SAS or SSD bays can be split into two sets of three bays for additional configuration
flexibility using just the integrated SAS adapters.
Two new SSD packages offer ordering convenience and price savings for a new server order.
Each 6-pack SSD feature (FC ESR2 or FC ESR4) for the EXP30 Ultra SSD I/O Drawer can
provide up to 140,000 I/O operations per second (IOPS) in just one-fifth of a 1U drawer. The
4-pack SSD feature (FC ESRA, FC ESRB, FC ESRC, and FC ESRD) can provide up to
90,000 IOPS. A 6-pack or 4-pack SSD must be ordered with the server, not as a later MES
order.
Other integrated features include:
򐂰 Enhanced I/O bandwidth with PCIe Gen2 slots compared to the PCIe Gen1 and PCI-X
slots of the POWER7-based Power 750
򐂰 Enhanced I/O redundancy and flexibility with two new, integrated POWER7 I/O controllers
򐂰 One hot-plug, slim-line SATA media bay per enclosure (optional)
򐂰 Choice of Integrated Multifunction Card options (maximum one per system):
– Dual 10 Gb Copper + Dual 1 Gb Ethernet (FC 1768)
– Dual 10 Gb Optical + Dual 1 Gb Ethernet (FC 1769)
– Dual 10 Gb Copper + Dual 1/10 Gb (RJ45) Ethernet (FC EN10)
– Dual 10 Gb Optical + Dual 1/10 Gb (RJ45) Ethernet (FC EN11)
򐂰 One serial port on the Integrated Multifunction Card
򐂰 Two USB ports on the Integrated Multifunction Card plus another USB port on the base
system unit
򐂰 Service processor
򐂰 EnergyScale technology
򐂰 Two SPCN ports and two hardware management console (HMC) ports (HMC is optional)
򐂰 Redundant and hot-swap AC power supplies
򐂰 Redundant and hot-swap cooling
򐂰 4-pack and 6-pack SSD features that can be ordered with a new server
